Introduction
The clock thermostat type WLCT is part of the underfloor heating system type WLM. The thermostat can be set to control one single room, or it can be set
as a master to control a group of thermostats / rooms/zones.
All the thermostats that are part of that group will follow the times and temperatures programmed into the clock thermostat. For example, if the temperature
programmed in the clock thermostat is 22°C, all the thermostats / rooms belonging to that group will then also be controlled at 22°C. Depending on the
types of thermostats used you can adjust the temperature + or -4°C in different rooms, giving a possible room setpoint of +18 to +26°C.
The clock thermostat can be programmed to work at different temperatures during the day allowing lower temperatures during times that the room is
unoccupied. Lower temperatures will lower your energy costs without reducing the comfort. All thermostats that are part of the group will follow any new
time or temperatures programmed in the clock thermostat.
When it leaves the factory, the thermostat has a preset program suitable for most installations.
You only need to set the clock and day, and define the thermostats / rooms that should belong to the group.
The thermostat has a pin button marked R (see fig. 1), allowing you, at any time, to reset the thermostat to the factory settings. These are listed at the end of
this manual with space for you to record your own weekly schedule.
