Programmable RF thermostat type RFWRT
IntroductionIntroductionIntroduction
This thermostat can replace any standard room thermostat, and is designed for use with gas or oil heating systems. If you
wish to control electric heating note that the current rating of the receiver is 3A resistive.
The transmitter is battery-powered and designed for wall mounting, using the backplate supplied. The receiver requires a
230V 50Hz supply and provides a volt-free contact to switch any load up to 3A @ 230V 50Hz.
The transmitter can be installed wherever you would normally fit a room thermostat.
The receiver should be wall-mounted close to the boiler.
The transmitter and receiver communicate with radio frequency signals.
Radio Frequency CommunicationRadio Frequency CommunicationRadio Frequency Communication
1)The factory default code for RF communication is 000. This should be changed if more than one control set is being
installed in any premises, or if unwanted operation occurs due to interference from any other radio frequency device.
See ‘F1: RF address code setting’ on the next page.
2)Ensure that different addresses are assigned to each thermostat set within the same installation. Note that there should
be a gap of at least one metre between receiver units to avoid RF interference.
3)During normal operation the transmitter sends signals at 10 minute intervals to ensure the receiver is in the correct
state. If for any reason a signal is ‘missed’ there will be a 10 minute delay until the next signal is sent. Alternatively you
can increase or decrease the temperature temporarily by pressing the up or down arrow keys. The temporary setting
will remain active until the next program time is reached.
Set time and weekday:Set time and weekday:Set time and weekday:
Insert the batteries into the transmitter; make sure that the batteries are inserted with polarity as indicated in the battery
compartment. Press and hold the select and set buttons for 3 seconds. The hour will flash—adjust with the up or down
arrow button, confirm with select button. Adjust the minute and the weekday in the same way. Press the Set button to
return to normal running mode.
Function and wiring of the receiverFunction and wiring of the receiverFunction and wiring of the receiver
1. All wiring should be carried out by a skilled person. Disconnect power before wiring. Fit a 3 Amp fuse to the receiver
supply.
2. Install the receiver adjacent to the heat source. The area should be free from any damp, or sources of electrical / mag-
netic interference (e.g. hi-fi speakers). The receiver should not be screened by any metal object(s).l
3. If required, change the RF address code—see ‘F1: RF address code setting’ on the next page.
4. The receiver’s red LED illuminates to confirm a mains supply is present. The green LED illuminates when the output is
on, following a demand signal being received from the transmitter.
Test the RF communicationTest the RF communicationTest the RF communication
It is important to site the transmitter and receiver in suitable locations, such that the RF signal cannot be interrupted. The
range within buildings is 20—25 metres, but this can be affected by e.g. thick stone walls, foil backed plasterboard, metal
objects such as kitchen appliances etc.
Test the set in the following way:
1. The default temperature display shows the current room temperature. Press the up button until the set temperature is 2
degrees higher than the current room temperature.
2. Wait for a few seconds. The animated flame symbol should be seen in the bottom left-hand corner of the display.
3. Check the receiver. The green LED should be visible, and (if connected) the heating system should be running.
4. Press the down button on the transmitter to reduce the temperature below the current room temperature. Wait for a few
seconds. The animated flame symbol should disappear, and the green LED at the receiver should switch off.
5. If responses do not occur as expected during steps 1—4 above, press the reset button on the transmitter and repeat
steps 1 – 4.

tional heating installations, connections will be required to terminals 1— 4 only. Terminal 5 can be ignored.
