Heating or cooling module

• Function: The heating or cooling module controls the heating or cooling in four zones or rooms.

The module has four outputs to operate control valves (e.g. electronic valves at 230 V AC or 24 V DC), pumps, electric heating units or individual cooling units (e.g. air-conditioning units or fan convectors) in four different zones or rooms. This allows you to apply different heating or cooling settings to each one of the four zones or rooms fitted with a Niko Home Control thermostat. The module uses one output to control the heating or cooling system. When the module receives a heating or cooling request from the Niko Home Control thermostat in one of the zones or rooms, the H/C contact of all the modules will be closed which then activates the central boiler or cooling unit. The most centrally located boilers or cooling units are fitted with an input contact (e.g. a telephone or boiler contact) for this purpose. If not, a special regulation module will be added to the central boiler or cooling unit. In installations with a hot water reservoir, the circulation pump will be activated. To avoid conflict in the installation, the module takes into account the opening and closing times of the electronic valves as well as the lag time of the heating or cooling system .

When the module is functioning properly, the STATUS LED will light up in TEST mode only. If one or several errors occur, the LED will blink to indicate the error code of the error with the highest priority.
