Zone communicator

(VT.ZC8.0) The zone communicator is used to transmit signals (on/off) from room thermostats to the servo drives of thermostatic valves that control the flow of coolant through the circuits.

The use of the communicator facilitates the installation of automation and makes it possible to group thermostats and servos (servos of one group are switched on by the signal of one thermostat). Communicators can be combined among themselves in blocks to increase the number of managed channels.

The communicator has a relay output for controlling the circulation pump of the heating system. If there is no request for heating (all the thermostatic valves are closed), the pump automatically turns off, thereby saving electricity and extending the life of the pump.

Number of channels – 8, the number of communicators, united in one block – 3, supply voltage – 24 or 220, V, type of servo units – NC and NO.
