MANIFOLDS AND ACCESSORIES Junction box VT.ZC6
The VT.ZC6 zone communicator is used to transmit the control signal (on/off) from the room thermostat to the actuator of the thermostatic valve, which controls the supply of coolant through the heating circuit. The use of a communicator simplifies the control scheme, allowing you to group thermostats and servo drives (group servo drives are turned on by a signal from one thermostat).
Additionally, the communicator has a relay output to control the circulation pump. If there is no heating demand in the room, turn off the pump. This saves energy and extends the life of the pump. Compatible with thermostats VT.AC609, VT.AC701, VT.AC710 without installing additional equipment, and servo drives VT.TE3041.0.024
