8/5 Loops Zone Central Heating Controller Floor Hot Water System Pump Valve Actuator Heating Controller Accessories Features: CCT-25/CCT-28 is a multi-zone central heating system intelligent hub controller 5/8 channel concentrator with indicator. The thermostat corresponds to the zone valve, which is indirectly connected to the actuator. Up to 3 NC actuators can be connected to 1 zone. In the zone heating system, the actuator opens and closes the valve according to the thermostat setting of the zone. Each thermostat controls the heating independently to heat different areas of the house. The intelligent multi-zone central heating system controller is a 5/8 channel thermostat controller with indicator light. This unit is used to centrally process floor heating or thermostat signals, transmit 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. Specifications: Part name: Heating controller Material: ABS Color: White Size: 177*110mm Power supply: 100-240VAC, 50/60Hz 10A Passive output (boiler): 8A Circulation pump output: 250VAC, 8 (5) A No electrical connection: 1 normally open (common terminal) Number of circuits: 8 loops or 5 loops.
