Domestic hot water control
It is possible to control the domestic hot water temperature with a special version of the WLCT2, called
WLCT2-X9/HW) to ensure optimum energy saving.
A hot water sensor is connected to the controller and measures the temperature in the storage cylinder.
• To change the temperature of the domestic hot water, just change the set point in
the WLCT2-X9/HW by using the up or down button.
• The 4-event system in the WLCT2-X9/HW can be used to save energy when hot water
is not needed..
radiator control
It is possible to control a radiator circuit room temperature with a special version of the WLCT2 called
a WLCT2-X9/R) to ensure optimum energy saving.
The controller measures the temperature in the room, and a zone valve is then controlled via the WLM2
master, which in turn activates the boiler on demand.
• To change the temperature of the radiator circuit , just change the set point in the WLCT2-X9/R
by using the up or down button.
• The 4-event system in the WLCT2-X9/R can be used to save energy when heat is not needed.
2 step heating
A special version of the WLCT2 called WLCT2-X9/2 is capable of controlling an additional heat source
in a room. In addition to the primary under floor heating output, the room controller is now able to
control a second output as a boost function, which will be activated only if the temperature cannot be
achieved by the primary under floor heating output within a preset time period.
The Room Controller is used as a standard WLCT2.
If required the settings for when the second heating output is needed can be changed in the service
menu in the WLCT2-X9/2.
An additional Menu entry “2 st” can be found.
In this menu two parameters can be changed:
Temp:
If the actual room temperature is higher than the setpoint minus this setting, the second
output will not be activated.
Time:
This parameter decides how long the actual temperature is allowed to remain below the
setpoint minus the TEMP setting before the second output is activated.
