Temperature control for comfort and setback periods can be used individually or together. This can also be used in
conjunction with the timer mode options.
The temperature control feature will effectively maintain the set room temperature.
The target temperature can be set using the knob marked COMF located at the
back of the controller as shown below. The range is 15ºC - 35ºC. Once the room
temperature reaches the set temperature, the indicator will change from green to
yellow. When the room temperature drops, heating will became active and the
indicator will change to green.
In this mode, the controller will set heating active when the room temperature drops
below the set temperature. This feature can be used for frost protection or in situations
where a minimum room temperature must be maintained. The setback temperature
can be set using the knob marked SETB mounted on the back of the unit as shown
above. This can be set from 0ºC - 15ºC.
Temperature control for Setback period
For this mode, the switches are set as shown below.
If the heating is active in the setback mode, the indicator will illuminate blue.
Temperature control for Comfort period (where being used for an internal application)
For this mode, switches are set as shown below.
4. Temperature Control Mode
The temperature and/or timer settings can be changed after installation. It is important to switch the power off to
the controller before the changes are made. After the changes are made and the power is restored the new
settings will take effect.
5. Changing temperature or timer settings after installation
The controller can be switched off using any external device with voltage free contacts. For
example, timers or a building management system.
If this function isn’t used, a wire link across the external input connectors must be used.
When the external input connection is open, the indicator will illuminate red and the heating
will be disabled. However, setback mode will still operate at low temperature.

7. Choosing a position in a room
The SLPBWP controller should be fixed to the wall. Avoid areas with draught or direct sun. Do not position the
controller above or close to the heaters or other heat sources. Avoid installing the controller in areas where there
are metal objects between the heater and the controller. This will reduce the RF range. The RF range in ideal
conditions can be up to 20m however this can be reduced when the signal is passing through the walls or other
objects. The range can be also affected where the controller is mounted close to power cables, motors or
equipment producing a strong electromagnetic field. If the temperature control feature is used it is necessary to use
one controller for each room or zone.
8. Connection to the Main Supply
For the mains power, connect L, N & E wires to the connectors marked as L, N & E.
Electrical installation should be carried out by a competent installer, preferably registered with NICEIC (National
Inspection Council for Electrical Installation Contracting) in accordance with the 18 edition of the IEE Wiring
Regulations, (BS.7671), and any relevant Local Authority Bye-Laws.
