Installation sequence Description(only for type VMN3) The heating circuit module (control) is a temperature The process is controlled by gradually opening and controller for the heating medium in the system. It is closing the valves at specified time intervals. The valve equipped with a mixing valve with a servomotor.
Installation sequence Connection(only for type VMN3) The control unit exchanges information about operating parameters with the master appliance (boiler). Configuration parameters are set in the configuration menu. To connect the control unit to the master appliance, a unique identification number must be assigned (see section 4.2 in configuration mode).
