Setting up Which Room sensor Should Work With Which Thermal Actuator
Each Room sensor can be selected to operate a specific output which in turn controls the thermal
actuators on the manifold. Under the front cover of the Room sensor, a selector can be accessed,
and the number of its output (its CH channel) 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. (see later). A WLM
master has 8 outputs and additional slave module 6 outputs, and can be connected creating a
system of 14 individual zones.
Please note that channels 10 to 14 are marked as A through E on the selector,
A Room sensor set for CH1 will activate the thermal actuator connected to output 1 on the master.
The channel number can be selected without any power connected to the system. The channel of
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, the temperature
control will work according to the average temperature of both Room sensors.
Channel 0:
Each Room sensor is delivered with the switch in position 0 ensuring that it must be set to operate
correctly. Channel 0 can also be used for a Room controller controlling a group of Room sensors
where the control position should be somewhere central, e.g. the kitchen, rather than in the area
where the Room sensors are installed. Setting it to Ch 0 means that times and temperatures are
set on the WLCT for the group, but that the WLCT will not control a specific output itself.
Channels 1..14:
A Room sensor set for channel 1 will activate the thermal actuator connected to output 1 on
the master. If several Room sensors are set to the same channel number, they will control in the
following way,
- The actual room temperature is calculated as an average.
- The room temperature set point is calculated as an average.
- If a limit sensor is connected to the Room sensors
The lowest value of any Limit sensor is taken as the MIN Limit Temperature.
The highest value of any Limit sensor is taken as the Max Limit Temperature.
