CONTROLLING MULTIPLE RADIATORS FROM A SINGLE PROGRAMMER
To control a series of radiators from a single programmable thermostat, some changes need
to be made to the DIP switches and jumpers in order to adjust the RF address code setting.
Each receiver unit can only respond to RF transmissions from a programmable thermostat
that has the same RF address code setting.
Disconnect AC power to the receiver
unit and remove batteries from the
programmable thermostat before
attempting any adjustments of the RF
address code switches and jumpers. If
you are not sure how to carry out this
procedure correctly, please contact a
qualified electrician or heating
engineer.
To adjust the RF address code of any
receiver unit, simply push up one or
more of the five DIP switch levers on
the DIP switch bank which is located
on the back of the receiver unit. The levers are labelled 1-5 from the bottom to top, as shown
in the picture above. To avoid confusion, make a note of the setting of each switch.
To adjust the RF address code of the programmable thermostat, remove one or more of the
jumper caps located on the back of the unit (labelled 1,2,3,4,5 and shown in the picture
below) so that the jumper settings match the settings made on the receiver unit.
For example, if the DIP switches on the
receiver were set as follows:
1 - ON
2 – OFF
3 – OFF
4 – OFF
5- ON
Then you would need to remove jumper
caps 2, 3 and 4 on the programmable
thermostat to make sure that the codes
match. Retain all jumper caps for future
use. RESET must be pressed after
making any changes.
TESTING THE SETUP
Upon completion of the installation it is necessary to test each receiver unit. If any one unit
seems to function abnormally, try changing the RF address code of the corresponding
programmable thermostat, making sure that the new RF address code is different to all
others in the installation. The programmable thermostat sends On/Off signals every 10
minutes to ensure that the receiver is in the correct state. If, for some reason, the first RF
signal is interrupted, you may notice the programmable thermostat has stopped or started
calling for heat but the receiver hasn’t switched. Simply wait 10 minutes until the next signal
and the receiver should then switch correctly.
