We recommend the preparation of an area schedule chart on the backside of the user manual before
commencing the installation. This identifies piping circuits to specific rooms and enables the correct
allocation of a channel number in the WLM system.
Mount the Master and AO modules in the correct way on the wall in accordance with electrical
regulations.
Connect the AO-module, using the special cable included in the box.
Mount the Room sensors/controllers in the rooms, and set the channel switches to correspond with
the number of the actuator controlling that room.
For hardwired Room sensors/controllers now connect the 2-wire bus to the master or the AO module,
maintaining continuity of positive + and negative - connections.
For wireless Room sensors/controllers now insert the batteries.
If the Room sensors/controllers are of wireless type connect the receiver (WLRC-19) using the special
cable enclosed with the receiver.
NB: For Room sensors with floor temperature limiting sensors, please refer to separate instructions
included with Room sensors/controllers.

SETTING UP THE SYSTEM
Turn on the power supply.
Set the clock on any WLCT room controller:
a. If the hour digit is not flashing, press the small pinhole button with the clock symbol, otherwise..
b. Adjust the hours and press OK.
c. Adjust the minutes and press OK.
d. Adjust the day number (1 = Monday) and press OK.
In addition to its own room, the WLCT room controller can be used to set the operating times and temperatures of other Room sensors
(channels).
To achieve this, do the following on the WLCT room controller:
a. Enter the “InFo” menu by pressing the up and down button simultaneously for 4 seconds.
b. Find the “ArEA” menu with the down button and press OK.
c. The display shows “CH 1” (channel 1).
- Press OK button.
- Select “On” if this channel (Room sensor) should be controlled by the WLCT room controller, or “OFF” if not.
- Now press OK button to get to the next channel (CH 2) and repeat this step until all required channels have been selected “On”.
d. After all channels are set up, find the “ESC” menu entry and press OK.
NB: If different times and temperatures are required for other channels (Room sensors) within the system, more than one WLCT room controller can
be used. Care must be taken to ensure that the action of selecting a channel “On” is not made on more than one
WLCT room controller.
Switch on DIP-3 to activate learn mode:
All wireless Room sensors now have to be initialized:
- Analogue Room sensor (TA,TD,TM,TP) by pressing the internal
init button (Button learning mode) until a beep is heard.
- Digital Room sensor (CT) by pressing the pin hole button with the
clock symbol until a beep is heard.
Switch off DIP-3 to de-activate learn mode:

TESTING THE SYSTEM:
1. Switch on DIP-3 to activate learn mode: - power light will blink quickly
2. Each red channel light on the master should now be lit if a Room sensor is present on that
channel.
3. Switch off DIP-3 to de-activate learn mode again – power light stops blinking.
4. Turn all adjustable temperature settings on the Room sensors to minimum.
5. Switch on DIP-1 on the master to activate install mode (Install mode will be active for 2 hours
- Pumps, boiler, mixing valve and actuators should now be off)
6. Turn the temperature setting on the adjustable Room sensor in room 1 to maximum. The red
channel 1 light should be lit and the actuator on output nr. 1 will be activated, and will open
after 1-3 minutes, depending on the type of actuator.
Important: If the Room sensor is of a wireless type a delay of up to 5 minutes may occur
before the channel light becomes illuminated .
7. Check that the UHF pump is running and the mixing valve (only FS master) opens .
8. Repeat step 6 on all rooms.
9. Boiler test function:
Switch on DIP-2.
This closes the boiler start relay contacts for 1 minute.
10. To end all tests:
- Switch off DIP-1 to deactivate install mode.
Switch off DIP-2 to deactivate boiler test.
- Set all temperature knobs to default positions
Room sensors (TA,TD,TM,TP) to zero (center position).
Room controllers (CT) recommended to 21˚C.
- Set all override switches on TM and TD Room sensors to automatic position (clock symbol).
11. The system is now operating automatically.
NB: Other important settings can be found in the User manual on the pages shown bellow:

Problem Possible cause & solution
Make sure the power light is fast blinking. If not then put DIP-3 to ON position.
2-wire bus may be incorrectly connected. Voltage at each Room sensor should not be
lower than 4.0V (check for + & - continuity and short circuits)
For wireless Room sensors, please check that the batteries have been inserted correctly.
Has the init button been pressed ?
For wireless Room sensor check that the WLRC-19 (receiver) is correctly connected.
For channel 9-14, is the AO module correctly connected to the Master.
Make sure the Room sensor in that room is set to the correct channel number.
The channel selector on the Room sensor may be slightly out of position, try rotating and
the set it again.
Channel light is not coming on.
(When in Learn mode)
(When in Install mode, when the Room
sensor is activated (set to maximum))
Master is not in install mode – after 2 hours the master automatically de-activates install
mode – please reset the DIP-1.
Make sure the Room sensor in that room is set to the correct channel number. (two Room
sensors could be crossed over)
The actuator on the manifold has not
opened after 3 minutes.
Check the red channel light is illuminated.
The actuator for the room is not connected to the correct output on the master.
Bad electrical connection between actuator and terminals.
Actuator may be faulty or manually locked.
UFH Pump not starting in install mode Bad electrical connection between pump and terminals.
Install mode is not activated.
Pump may be faulty.

p. 9
QUICKGUIDES
Room is too hot
(After running for at least 48 hours)
This could be caused by draughts within the wall cavities.
The Room sensor is placed in a position that does not represent the general temperature in the
room.
If the room is controlled by a CT Room sensor, check that the time and temperatures are set
correctly.
If the Room sensor has got an override switch (TM or TD), the switch may be set in the “day”
position.
For rooms with fl oor sensors, the minimum fl oor limit setting could be increasing the room
temperature above the desired setting.
Solar gain or extraneous heat source.
Room is too cold.
(After running for at least 48 hours)
The Room sensor is placed in a position that does not represent the general temperature in
the room. E.g. mounted on external wall or near an extraneous heat source.
If the room is controlled by a CT Room sensor, check that the time and temperatures are set
correctly.
If the Room sensor has got an override switch (TM or TD), the switch may be set in the “off”
or “night” position.
For rooms with fl oor sensors, the maximum fl oor limit setting could be preventing the room
reaching the desired temperature.
Insuffi cient heating capacity of the system.
Bad insulation creating large heat loss.

Appliances with this label must not be disposed off with the general waste. They must be collected
separately and disposed off according to local regulations.
Recycling of obsolete appliances
Each master module is capable of controlling 8 heating zones, each of which may use one or more
loops of piping, with one or more thermal actuators.
These zones are referred to later in this instruction as channels 1 to 8. If you wish to control more
than 8 zones, it is necessary to install ADD ON (AO) modules, each of which can provide another 6
outputs. The first AO module then controls channels 9 to 14,
