7. Installation
The controller is designed to fit onto most single gang back boxes. Do not use a recessed metal box for the
installation. The controller can be powered by either mains 240VAC 50Hz or 12VDC. The power consumption is less
than 1W. Do not connect mains voltage to 12V terminals, this will damage the controller. The maximum size wire
that can be used is 1mm2, this can be twin and earth or standard flex . Do not overtighten the connector screws.
Take care not to damage the components when connecting the cables. damage the components when
connecting the cables.
WARNING, this controller is not compatible with single gang metal back box with 4 fixing lugs.
6. Choosing a position in a room
The SLVT 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. Damp areas or areas where SLVT can be mechanically
damaged should also be avoided. 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 trough the walls or other objects. The range can be also
affected where the controller is mounted close to power cables, motors or equipment producing 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 and N wires to the connectors marked as L and N.
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 17 edition of the IEE Wiring
Regulations, (BS.7671), and any relevant Local Authority Bye-Laws. This heater is fitted with a 3-core mains supply
cable and should be permanently connected to the electricity supply via a double pole switch having 3mm gap
on each pole. A switched Fused Connection unit to BS.1363. Part 4 is a recommended mains supply connection
accessory to ensure compliance with safety requirements applicable to fixed-wiring installation.
10. Self Diagnostic
Powering the controller with 12Vdc
allows the controller to be installed in a
zone 2 area, however, the installation
must comply with the Separated Extra
Low Voltage (SELV) requirements. When
powered by 12VDC, please ensure that
the power supply is suitable for 12V 0.1A.
For 12VDC power connect positive wire
to terminal 12V and negative to
terminal marked –12V.
Please note: A 12Vdc power supply does
not come with this controller, however, a
standard 12Vdc constant voltage LED
driver could be used.
9. Connection to 12V DC
The controller is equipped with a self diagnostic software that will check functionality of all main components. If
there is a fault with any part of the controller or controller is operating outside of the temperature limits, the 4
indicators will flash red . If this happens, controller will not function in order to protect itself and the heaters.
11. Pairing with heaters
In order to pair your appliance with the controller you must:
·
Ensure that the controller must be in OFF position (the light segments off or red).
·
Turn power to the appliance ON.
·
Within 20 seconds, press and hold the ON button on the controller until the orange segments light up in a
sequence.
·
After the pairing is finished, the light segments will change to green.
·
If the pairing was successful, the appliance should emit heat. It can take up to 4 seconds.
·
After 4 seconds, the appliance will be switched off.
·
The appliance is now ready to be used.
