About the Nu-Heat System
System startup
Description
Underfloor heating works by pumping warm water through special plastic tubing
embedded in the floor. This warms the floor and maintains the room at a
comfortable temperature.
Benefits
In particular, underfloor heating systems:
•
Provide a more comfortable heated environment,
•Permit unlimited interior design options,
•Increase the useable space within a property.
Moreover, all these benefits are available from a system which can be significantly
less expensive to run than a conventional, radiator-based system.
Underfloor heating
Locate the main components of your
installation: the boiler, hot water cylinder,
underfloor heating pump/Optiflo
manifold assembly(s), thermostats,
timeclocks, underfloor heating
wiring box.
Electricity supply
Ensure that the electrical installation is
complete and that the heating system
is turned on. The location of the main
supply on/o switch may vary but is
often positioned next to the boiler.
There may be additional switches located
at each underfloor heating wiring box
which also need to be on.
Water supply
Ensure that the water is turned
on ready for domestic hot water
operation, check that a high flow of
water is available from the cold taps.
If there is poor flow or none at all,
check that the stop-cock for the
property is fully open.
Once your system has been commissioned it should be fully operational. To initially
check that your system is turned on and working please follow these simple steps:

Operation
Your underfloor system is designed for
performance and economy. Each heating
zone is controlled by its own wall-mounted
thermostat. If a room has no thermostat
it will be connected to, and controlled
by, an adjacent zone.
UNDERFLOOR HEATING
Unlike traditional dial thermostats
controlled by a timeclock,
programmable thermostats do not
work on the basis of ON and OFF
times. Instead dierent temperatures
are set at dierent times throughout
the day. If the property is to be
unoccupied during the day, for example,
then the temperature can be set low
(setback temperature), whereas during
the morning and evening it can be set
at the desired comfort temperature.
The best way to find the optimum
temperature setting is to set a low
comfort temperature (e.g.18°C) and
then turn it up by 1°C each day until the
temperature is right.
Consideration should be given to the
dierent floor constructions and
finishes used in your property, as these
factors will aect the time the system
will take to achieve comfort conditions.
However, the neoStat incorporates
Optimum Start, a self-learning feature
that enables it to manage when the
heating should be switched on, in order
to hit the target temperature that has
been programmed. This means that the
thermostats can be set to the comfort
temperature at the times
that heating is required. It will then
automatically manage the varying floor
response times, and bring the heating
on in time.
The Optimum Start feature will need to
be set up in the thermostat – for details
see page 13.
The temperature chosen as the setback
temperature will depend upon the
situation:
•
For new build properties this will
generally be 4-6°C lower than the
comfort setting, although again, this
can be experimented with.
•
Renovated properties may work best
with a lower setback temperature,
in order that the heating remains o
outside of the times at which the
comfort temperature is selected.
The fast response time of LoProMax
™
makes this method particularly
suitable.
•
Less thermally responsive floors, in
particular screed floors greater than
65mm thick, will achieve comfort
temperatures more quickly when
the setback temperature is closer
to the comfort temperature.
Boiler Plus legislation
Following a report called Heat in Buildings, published in October 2017, Boiler Plus
legislation came into force in April 2018. It staes that:
Time and temperature controls must be installed with any new boiler, if not already
present

HOT WATER CONTROL OPTION
A supplementary neoStat can be configured as a timer to control your hot water.
See page 16 for details of how to set this up.
Each room thermostat combines the functions of a room
thermostat, timeclock and set-back thermostat.
For enhanced heating performance and eciency the unit also provides
self-learning Optimum Start in the morning.
To comply with Boiler Plus legislation with a new gas combi boiler, select the
Optimum Start feature on all thermostats during installation.
Four adjustable time/temperature zones are available for the days of the week, and
a further four during the weekend as standard, giving enhanced heating control.
A 7-day mode is also available.

SmartPhone (systems with neoHub+)
PAIRING THE NEOHUB+
PAIRING THE NEOSTATS
The next step is to pair each neoStat to the neoHub+, starting with the neoStat located nearest to the neoHub+.
To add a neoStat, follow these steps:
WHAT IS A MESH NETWORK?
NeoStats work using a mesh network, meaning neoStats have
the ability to send and receive signals via other thermostats
on the network. This signal is relayed from one thermostat to
another until it reaches its destination. This communication
method extends the communication range whilst oering
increased network stability when compared with standard
RF thermostats.
The MESH symbol is shown when the device is communicating
with the neoHub, if the mesh symbol disappears this
indicates connection to the neoHub+ has been lost.
To pair the neoHub+ with the neoApp, follow these steps:
1
Connect the power supply to the neoHub+.
2 Connect the neoHub+ to your router with the Ethernet
cable provided. The router will automatically assign an IP
address to the neoHub+, the ‘Link’ LED will light up RED
once the neoHub+ has connected to your network.
Once connected to the cloud server, the Link LED will
turn GREEN.
3
Connect your smartphone or tablet to the same WiFi
network as your router.
3
Download the FREE Nu-Heat neoApp from the Apple App
Store, Google Play Store or Windows Phone App Store
and register an account.
4
Once you have registered your account, press SIGN IN
then press ADD LOCATION.
5
Press the CONNECT button on the neoHub+to add the
location to your account.
6
When successfully connected, enter a title for the new
location (e.g. Home).
1 From the neoApp, select ADD NEOSTAT, enter a zone
title and press NEXT.
2
You now have two minutes to pair the neoStat to the
neoHub+.
3
On the neoStat, use the < / > keys to select setup and
press POWER. Press and hold 3.
4
SETUP will be highlighted, now press the 3 key once.
5
Feature 01 is displayed on the screen.
6 Press the Tick key once again to pair the neoStat to the
neoHub
7
The MESH symbol appears flashing on the display.
8
When the neoStat successfully connects to the neoHub
the MESH symbol will be permanently displayed.
9
Press ADD ANOTHER for addtional zones or press FINISH
to complete setup.
Please note, you only have to pair the hub to your account once. To pair any additional neoStats, select ZONES, edit, then
ADD ZONE.
APPROACH SENSOR
The neoStat V2 uses proximity to detect when you are about
to use the touch keys. As you approach the neoStat V2, the
touch keys and backlight will light up.
This can be useful if you need to adjust the set temp or timer
in a dark room.

General system checks
The expansion vessel and filling loop is
usually positioned near the boiler.
Adjust the temperature of the boiler water
by turning the boiler control thermostat.
Never set the boiler water temperature
lower than the cylinder thermostat.
System pressure
The majority of heating systems are
sealed and include an expansion vessel
which maintains the system pressure.
This red vessel would normally be
found positioned near to the boiler.
If you have a combination boiler or
system boiler the main pump and
expansion vessel will be inside the
boiler. The best way to identify this
is that the boiler will have a pressure
gauge on its panel.
You will need to check the system
pressure regularly as it is normal for
a system to lose a small amount of
pressure. The gauge should read
approximately between 1 and 2 bar
depending on whether the system is
cold or hot.
If the pressure is below 1 bar, top the
pressure up to 1 bar by opening the
valve on the filling loop connected to
the red vessel (or boiler if no red vessel
is fitted). Only top up when the system
is cold. If your system rapidly looses
pressure you need to consult a heating
engineer.
If there is no red expansion vessel or
gauge on the boiler then your system is
not sealed but open vented and will be
topped up automatically by a feed tank
and ballcock in the loft.
Boiler thermostat
The temperature of water generated by
your boiler is altered by adjusting the
boiler control thermostat dial.
If you have a hot water cylinder it
is important that the boiler water
temperature is always at least 5˚C
above the temperature of your
cylinder thermostat.

General sequence of operation
Every time heat is required in a room the following sequence is initiated:
If the heating is in an on period and the room requires heating, the room
thermostat will call for heat :–
1 A flame symbol will appear on
the display.
The floor pump, either on the
Optiflo manifold serving that zone,
or on the remote-mounted pump
module will be switched on.
The actuator on the Optiflo
manifold circuit connected to the
zone will open, indicated by the button
on top of the actuator head rising.
The flow gauge on this circuit will
indicate flow and the flow pipe will
get warm.
Over a period of time as the room
comes up to temperature, the return
pipe will warm up as well.
For standard systems with conventional
boilers/cylinders or combination boilers
the boiler and boiler pump are turned
on to supply and circulate heat.

Seasonal adjustments
Leaving the property unoccupied
in winter
Rather than turning the heating system
o, it is possible to leave background
heating on as frost protection.
Each room/zone can be set to frost
protection individually. Please refer
to the instructions (Frost Protection
on page 11), which detail how the
thermostat can be put into a hold
mode and the required frost protection
temperature adjusted.
Instant hot water and heated
towel rail
Hot water and heated towel rails will
be available all year round regardless
of your requirement for underfloor
heating.
If you require to turn the heating o (for example when servicing) always use the
main heating isolation switch.
Underfloor heating can be left active
all year round as it is thermostatically
controlled by the room temperature. In
warm weather it will simply not come on.

Geo-Location
UNDERSTANDING & SETTING UP GEOLOCATION
Geo Location is a feature that makes use of a smart phone’s location services to
turn the heating o when the homeowner is out and back on for their return.
It works by the setting of a Leave and Return Trigger distance along with a required
temperature. When the triggers are activated, Neo will automatically adjust the
temperature in the home. It also works with multi users, so will only adjust the
heating when the last person leaves and the first person arrives home.
Ideal uses for the Geo Location
•
Automatically turn the heating o when you’re out, perfect for weekends when
you may have your heating programmed to be on all day.
•
Always return to a warm home. For those occasions when you return home
outside a programmed heating period, Geo Location will automatically turn the
heating on and then turn it o when you leave.
Note: Geo-Location works well for radiators and for LoPro™Max, which respond
quickly. However, for other UFH floor constructions, with longer response times,
Geo-Location will not necessarily give the desired performance and comfort.

Things to remember
1
Account per User – To use Geo Location – each user in the home must have
their own Share Account.
2
Enable Location Services – Geo Location uses your phones location services,
so you must have this enabled for the Geo Location feature to work.
3
Enable WiFi – Geo Location uses WiFi to get a more accurate lock on your
position. Your phone doesn’t need to be connected to a WiFi network for this to
work, your phone will constantly scan available networks and use this data to
more accurately determine your location.
4
Last Out – First Home – Remember that Geo Location will only turn the
heating o when the last person has left and back on when the first person
arrives home. You will receive a notification on your phone if the temperature
in your home has been adjusted because of your location.
5
Location Services – If you setup a 1 mile leave trigger, your phone will send
a signal to your neoHub+to reduce the temperature in your home once your
phone’s location services indicates to the neoApp that you have passed this
point. Your phone will determine how often to update your location – it does
this to reduce the impact on battery performance. Therefore, you should expect
a slight delay after passing the trigger point before Neo adjusts the temperature in
your home.
Privacy
• Neither Nu-Heat nor the manufacturer ever knows or stores your home
location or your current position.
• Only your mobile phone knows your home location and your current
position. Using this data it calculates when you have passed the configured
trigger points.
• The state (Home/Away) is stored on the neo Server per user, and this is used to
calculate when everyone has left home therefore allowing neo to reduce the
temperature or to calculate when the first person is arriving home.

System adjustments
To do this:
When the system is operating, turn the
thermostat up in that room.
Identify from the pipe markings at the
manifold which actuator head serves
the zone you want to change.
Note: If the zones are not clearly
marked turn o all the other room
stats. The zone that is operating will be
shown by a raised button on the top of
the actuator (1) and the flow gauge will
indicate a flow reading (2).
Please note that the button can take up
to 3 minutes to respond.
To adjust flow rates on the flow gauge
(see diagrams below):
a
Remove red collar
b Undo the black locking nut
c Adjust the flow rate as required, by
turning the gauge with the red ‘key’
d Re-tighten the black locking nut
e Replace red collar
f Zone can be isolated by winding
flow gauge all the way down
g Re-open zone by winding flow
gauge up until stopped by the
locking nut
Note: Adjust a little at a time to suit
your requirements. Increasing the flow
to one zone may decrease the flow to
others. There is a limit to how much
extra flow can be achieved and if, after
adjusting one or several zones, further
action is required the flow temperature
can be increased.
To do this:-
With the system running note the
water flow temperature on the gauge
(3) on the top rail of the manifold. This
temperature can be increased (see 4a
and 4b below).
Note: Adjust a little at a time to suit
your requirements.
If additional heat is required in a selected room or rooms the
water flow rate(s) serving these areas can be increased.
