1.0 Introduction
1.1 Introduction
1.The kit consists of a Programmable
Room Thermostat Transmitter (Fig. 1) and
a Receiver Unit (Fig. 2) operated by radio
frequency, various fixings, 3 x AAA
batteries and a warning label.
2.TheTransmitter constantly monitors the
temperature of the room in which it is
installed. It can be operated in three
temperature modes,‘Lo’,‘Hi’ and ‘Frost
Protection’ or left in ‘Automatic’ to
operate as programmed.
3.TheTransmitter must be located as
described in the next section.
4.The Receiver can be fitted anywhere in
the property relative to the appliance as it
is wired directly to the appliance switched
live, providing good radio frequency
communication will be maintained.

2.0 Locating the Transmitter
2.1 Location
1.To ensure optimum operation of the
appliance and to achieve the desired
comfort levels the Programmable Room
Thermostat Transmitter must be correctly
located (Fig. 3):-
• In the main room of occupation
• Away from sources of
heat/light/draught
• On an internal wall at a height of
approx. 1500mm*
*Alternatively the Transmitter can be fitted
with the supplied plinth to allow free
standing on, for example, a sideboard or
shelf. It is recommended that the
Transmitter is operated free standing for a
period in several locations to determine the
best position.
2. It is important that no large metal objects
or mirrors are placed between the
Transmitter and Receiver, as they may
interfere with the Radio Frequency signal.
This could prevent the appliance working or
cause intermittent operation.
2.2 Fitting (Fig. 4)
1. Remove the cover by inserting a
screwdriver and twisting as shown.
2. Remove the batteries and insulating strip.
3. Select a suitable position for fitting and
mark the wall through the backplate, or fit
the free standing plinth (see above).
4. Once the optimum position has been
established drill & plug the wall (if wall
mounting). Secure the Transmitter with the
screws supplied and refit the batteries.
Replace the cover.
