CHOICE RSTAT9
Digital RF Programmable
Room Thermostat
with wall mounted receiver
Introduction
The Choice RSTAT9 comprises of a portable battery
powered thermostat (transmitter) for accurate
temperature control and a separate wall mounted mains
relay box (receiver). The transmitter is located in the main
living area and the receiver is mounted close to the boiler.
This programmable room thermostat has been designed
to bring you comfort and energy economy. It allows you
to program and regulate your heating system using up to
6 programmable events per day.
The thermostat provides clear feedback to the user of
the current time and temperature and depending on the
program settings transmits RF signals to the wall mounted
receiver to switch the boiler or zone valve appropriately.
To ensure its correct operation the thermostat should be
mounted or situated approximately 1.3m above the floor
and away from direct sunlight, heat sources and drafts.

Installation
This product must be installed by a competent
person in line with the latest IEE regulations.
Isolate mains before commencing installation of the
product.
As these products communicate using RF technology, it
is important to consider location of the RF components
as well as the building structure as they may influence
performance of the RF system. It is important to take
into consideration that walls and ceilings will reduce the
RF signal. The two products should communicate reliably
within a 30m range.
Receiver
Loosen the supplied wall plate from the receiver and
secure in the desired position in an open space away
from any metal objects including wall boxes and the boiler
housing.
Route wires through rear entry hole and connect wiring in
accordance with information printed on receiver.
Example circuit diagrams for typical installations are
shown below. For reasons of space and clarity not every
system can be shown
Insert Batteries
With the fascia unclipped from its backplate, fit supplied
AA batteries into the battery compartment shown. All LCD
data will flash. Press SET to stop the flashing.
Refit fascia to backplate by first locating bottom catches
and closing into position at the top.
Test Process
Check that the transmitter and receiver reliably communi-
cate in their installed positions.
Hold “TEST” button for 3 seconds, heating symbol
will alternate on or off every 5 seconds and it will last
2 minutes, whilst checking the receiver will be on or off
accordingly.
User Instructions
What is a programmable room thermostat?
...an explanation for householders.
A programmable room thermostat is both a programmer
and a room thermostat. A programmer allows you to
set ‘ON and OFF’ time periods to suit your lifestyle. A
room thermostat works by sensing the air temperature,
switching on the heating when the air temperature falls
below the thermostat setting and switching it off once the
set temperature has been reached.
So, a programmable room thermostat lets you choose
what times you want the heating to be on, and what
temperature it should reach while it is on. It will allow you
to select different temperatures in your home at different
times of the day (and days of the week) to meet your
particular needs.
Turning a programmable room thermostat to a higher
setting will not make the room heat up any faster. How
quickly the room heats up depends on the design of the
heating system, for example, the size of the boiler and
radiators. Neither does the setting affect how quickly
the room cools down. Turning a programmable room
thermostat to a lower setting will result in the room being
controlled at a lower temperature, and saves energy.
The way to set and use your programmable room
thermostat is to find the lowest temperature settings that
you are comfortable with at the different times you have
chosen, and then leave it alone to do its job. The best
way to do this is to set low temperatures first, say 18ºC
and then turn them up by one degree each day until you
are comfortable with the temperatures. You won’t have
to adjust the thermostat further. Any adjustments above
these settings will waste energy and cost you more money.
If your heating system is a boiler with radiators, there
will usually be only one programmable room thermostat
to control the whole house. But you can have different
temperatures in individual rooms by installing thermostatic
radiator valves (TRVs) on individual radiators. If you
don’t have TRVs, you should choose a temperature that
is reasonable for the whole house. If you do have TRVs,
you can chose a slightly higher setting to make sure that
even the coldest room is comfortable, then prevent any
overheating in other rooms by adjusting the TRVs.
The time on the programmer must be correct. The RSTAT9
automatically adjusts between spring and autumn at
the changes between Greenwich Mean Time and British
Position the receiver to the wall plate by locating onto the
top locating tabs and closing over and securing via the 2
fixing screws at the bottom.
Transmitter
Using a screwdriver release locking tab at the top and
separate the back plate from the fascia.
Install or Position Transmitter
The transmitter may be wall mounted or secured to its
table stand so it is portable. Use the test process below to
confirm operation.
