Based on the room temperatures, the master ensures optimum operation of boilers, pumps, and – on the digital master, water temperature control. It is especially important that operating temperatures are optimised as these are of crucial importance for energy consumption, and system service life.
The master is universal and can be used for wireless communication if a receiver is connected. Sensors with either wireless or cable communication can be combined in the same system.

Cooling functions
In addition to controlling heating, all WLM2 masters have the ability to control the system for cooling.
To enable the cooling function an interface module WLAC and humidity sensor WLH have to be connected.
By using the humidity sensor the system limits the formation of condensation on floor surfaces due to high humidity.
If cooling is being limited due to high humidity a dehumidifier can be enabled by the master.
When cooling is enabled the cooling set point will be pre-determined by the master and will override any settings in any room controller to ensure optimum energy efficiency.
