installation
setting up which room sensor is paired with which thermal actuator
Each room sensor can be set to operate a specific output which in turn controls a thermal actuator on
the manifold. A selector can be accessed under the front cover of the unit where the number of its output
(i.e. its channel number) can be set with a screwdriver (see fig. 10). Up to 14 channels can be set on the
selector, and there are two auxiliary channels with special functions. A WLM3 master has 8 outputs and
additional slave modules, each with 6 outputs, can be connected creating a system of 14 individual zones.
NOTE: Channels 10 through 14 are marked as A through E on the selector.
A room sensor set for channel 1 will activate the thermal actuator connected to output 1 on the master.
The channel number can be set before power is connected to the system. The channel set on the room
sensor can be changed afterwards if needed. If two room sensors are placed in the same room and set to
the same channel, temperature will be controlled by the average of the temperature recorded by both units.
Channel 0:
Each Room sensor is delivered with the switch in position 0. It must therefore be set to operate correct
channel output. Channel 0 can also be used for a room controller which is only used to control a group
(area) of room sensors without actually controlling the room in which it is installed (e.g. a controller in
the kitchen which is only used to control sensors located in other rooms). Setting the room controller to
channel 0 means that times and temperatures must be set on the WLCT3 for the group (area). The WLCT3
will not, however, control a specific output itself.
Channel 15 (F):
Special function. See “Special Features” for further instructions.
setting the room sensors to learning mode
Standard room sensors without display: Remove the front cover and push the small leaning mode button
for approx. 2 seconds until the room sensor beeps.
Room controller with display: Press the clock symbol for 2 seconds until “init” is shown on the display.
The room sensor will now transmit its unique code for the next 30 seconds, and the system has been set
up.
setting the master to receive signals from room sensors
(wireless only)
To set the master to learning mode, set DIP-3 to “ON”.
The master will now look for new room sensors that are also in learning mode. Remember to set DIP-3
back to “OFF”. ...RF LEARNINGMODE.. will be shown in the display if the master has one.
