Herz Space Heating Manifold Temperature Sensor Signal Distribution to Thermomotors 230V, Black (3f79803)

The electric distributor is utilised with an underfloor-heating distributor and serves as a distributor for the power supply, for the individual positioning signals and for a shared time programme (max. 2 channels). The distributor communicates the room controller command and the decrease signal to the thermal actuators. Terminals A and B serve as time channels for decreasing the set temperature. The time programme can be defined either using HERZ 3 F799 15-18 or via an external timer. The corresponding connection can be used to reduce all the other zones depending on the time. A pump can be activated directly via the two terminals provided. The pump logic is used to activate the pump according to requirements. The pump starts operating as soon as an actuator is active. So if none of the connected actuators are activated (i.e., valves are closed), the pump is switched off. A temperature limiter can be connected via the two TB terminals. The thermal actuators are switched off when the water temperature is too high or the dew point has been reached. The pump continues running.
