• Connect the hot water sensor to the controllers sensor terminals.
• Connect the hot water zone valve to an output on the WLM master and set the channel number
on the hot water controller to the corresponding number.
Note: When the WLCT/HW calls for heat it does not start the circulation pump on the under floor
heating system
Radiator control:
It is possible to control a radiator circuit room temperature with a special Room controller (WLCT/R) to
ensure optimum energy saving.
The Room controller measures the temperature in the room, and a zone valve is then controlled via the
WLM master, which in turn activates the boiler on demand.
• The WLCT/R must be fixed in a convenient position for the user, but which is representative
of the room or area temperature.
• Connect the Room controller to the WLM master using the sensor/controller bus.
• Connect the radiator zone valve to an output on the WLM master and set the channel number
on the Room controller to the corresponding number.
Note: When the WLCT/R calls for heat it does not start the circulation pump on the under floor heating
system
2 step heating:
It is possible to control a of a secondary heat source in a room (e.g. a backup radiator), use the
spesial mode in the WLCT/2 Room controller. In addition to the primary underfloor heating output,
this WLCT/2 room controller is able to control a second output as a boost function, witch will be
activated only if the temperature cannot be schieved by the underfloor heating within a preset time
period.
• The WLCT/2 must be fixed in a convenient position for the user, but which is representative of the
room or area temperature.
• Connect the Room controller to the WLM master using the sensor/controller bus.
• Set the channel number on Room controller to correspond with the output on the WLM master that
is connected to the underfloor heating actuator.
• The next numerical output on the WLM master MUST be used for the secondary/boost function.
Note: To avoid overloading the WLM master, we recommend that the secondary output is used as a
signalling function for a remote relay.
