System Ref:
Please read this manual fully before fitting your Nu-Heat OneZone®floor heating
system. It assumes a basic knowledge of electrical wiring, and of common terms
used.
Attention to the advice given in this manual will help to ensure a trouble-free and
eective installation. The requirements of the relevant British Standards and other
Regulations should always be met.
In line with the company policy of product development, Nu-Heat reserves the
right to supply dierent components to those shown.
Please ensure that this manual remains with the homeowner when installation
is complete. It is a companion manual to the OneZone®Installation Manual, which
shows details of the plumbing components and floor construction.
This manual is the copyright of Nu-Heat. All rights reserved. No part of this
publication may be reproduced, stored in a retrieval system, or transmitted
in any form or by any means electronic, mechanical, photocopying, recording

Electrical components
neoAir wireless thermostat
NeoAir is a wireless, battery powered
programmable thermostat that is
capable of upgrade to smart control
(see neoHub below). The room/zone is
individually programmed for
temperature and times of use. This can
be independent control or in
conjunction with an existing radiator
system. For screed and floating floor
systems, allowance should be made for
the longer warm-up time of underfloor
heating. With LoPro®Max systems
response time is similar to that of a
traditional radiator system.
In order to comply with wiring
regulations bathroom zones must have
the thermostat fitted outside the room,
i.e. next to the door at light-switch
height.
RF Switch
This is the wireless base receiver, to be
fitted near to the OneZone®wiring
centre.
OneZone®wiring centre
The wiring centre can either be fitted
beside or remotely from the heating
components. It can be wired to suit
individual system requirements.
neoHub
The neoHub connects to a home
broadband router and wirelessly to
the neoAirs in a home. Simply plug into
a router, connect to your Nu-Heat
neoApp on an Android or iOS device
and take control of the underfloor
heating from anywhere.
neoPlug
neoPlug is a simple smart plug that
(with neoHub) enables on/o control
of a household appliance. It also acts as
a signal booster between the neoAir
and the RF Switch.

Planning the installation
1 Read this Installation Manual
carefully.
2Decide which control method is to
be used for the OneZone®under-
floor heating system (see opposite).
3Agree the position for the wiring
centre and thermostat with the
homeowner.
41st fix all electrical equipment as per
the chosen method of control.
5After the underfloor heating
pipework is installed, 2nd fix the
electrical components.
6Commission the underfloor
heating and test its operation.
7Explain the operation of the
OneZone®underfloor heating
system to the homeowner and
hand over this User Guide
for reference.

System control options
There are two ways to connect the system:
B – Connection is at the boiler
This arrangement gives optimum performance. It allows time and
temperature settings for the OneZone®underfloor heating system to be
independent of other areas of the home. It also enables use of a set-back
temperature facility to reduce warm-up times. Pipework is connected back
to the boiler side of any control valves.
What type of heating system do you have?
Combination boiler
Refer to page 10 for wiring details.
S Plan
The system has two 2-port zone
valves, one controlling the radiator
circuit and the other controlling
the cylinder. Refer to page 11 for
wiring details.
Boiler & cylinder
What type of system
control do you have?
W or Y Plan
The system has a 3-port zone valve
controlling both the cylinder and
radiator circuits. This system type
requires an additional 2-port zone
valve to be fitted. Refer to pages
12–13 for wiring details.
Don’t know
Please consult your heating
engineer or electrician.
Please consult your heating
engineer or electrician.
Don’t know
OR
A – Connection is to the radiator circuit
Pipework is connected directly to the radiator circuit meaning that time
settings will correspond to the radiator circuit and set-back operation is
not possible. With screed and floating floor constructions, heating operation
times for the whole system may have to be altered to allow for the
longer warm-up time of underfloor heating compared to radiators. With
LoPro®Max systems response time is similar to that of a traditional radiator
system.
Refer to pages 9 for wiring details.

REMOTE TEMPERATURE SENSORS
All OneZone®systems are supplied with a remote floor temperature sensor for
use with sensitive floor coverings such as engineered hardwood, vinyls (including
Amtico) and linoleums.
Note applying to all wiring diagrams:
All new electrical works must comply with IEE Regulations and health and safety
requirements, and be tested by a competent person before connection to mains
voltage.
