Features: CCT-25 is a multi-zone central heating system intelligent hub controller 5 channel concentrator with indicator. The thermostat corresponds to valve, which is indirectly connected to the actuator. Up to 3NC actuators can be connected to 1 zone. In heating system, the actuator opens and closes the valve according to the thermostat setting of . Each thermostat controls the heating independently to heat different areas of . The intelligent multi-zone central heating system controller is a 5 channel thermostat controller with indicator light. This unit is used to centrally process floor heating or thermostat signals, mit instructions to control the opening or closing of floor heating electric valves, and realize zone control. While controlling the electric actuator, the passive connection of the heat pump host, boiler and external water pump (mixing center) can be controlled.
