radiator Mode
Where a radiator circuit is used, it is possible to control room temperature using a special WLCT3 mode
called Radiator Mode, thus optimizing energy savings.
The controller measures the temperature in the room, and a zone valve is then controlled via the WLM3
master, which in turn activates the boiler on demand.
• For information on programming, see “Advanced Settings and Read-outs”.
2-step mode
A special WLCT3 mode called 2-Step Mode is capable of controlling an additional heat source in a room.
In addition to the primary underfloor heating output, 2-step mode is able to control a second output as a
boost function. This output will only be activated if the required temperature cannot be achieved by the
underfloor heating alone within a preset time period.
The room controller is used as a standard WLCT3.
If required, the settings for when the second heating output is needed can be changed by your service
engineer.
• For information on programming, see “Advanced Settings and Read-outs”.
Hot water mode
It is possible to control domestic hot water temperature with a special WLCT3 mode called Hot Water
Mode, thus optimizing energy savings.
A sensor is connected to the controller and measures the temperature in the hot water storage cylinder.
• For information on programming, see “Advanced Settings and Read-outs”.
