The CCT-25/28 itself does not have WiFi, only the temperature controller connected to the WiFi model can control the entire system through WiFi.

Note: CCT-25 and CCT-28 can only connect to water heating ontrollers and normally closed actuators, and the entire system intelligently controls heating but not cooling.

Product Description:

The CCT-25/CCT-28 is Multi Zone Central Heating System Smart Controller 5/8-Channel thermostat controller with Indicators.

This unit is used for the centralized processing of water floor heating or thermostat signals, and transmits instructions to control the open or close of the floor heating electric valve and performs zone control.
At the same time controlling the electric actuator, it can control the passive linkage of the heat pump host, the boiler and the external water pump(mixing center) .

Specifications:

Power supply: 100-240VAC, 50/60Hz 10A
Passive output (Boiler): 8A
Circulating pump output: 250VAC, 8 (5)A
No power linkage: 1 normally open（common terminal）
Number of circuits: 8 loops or 5 loops The max number of actuators in a circuit: 3pcs Output delay: 200s

How does Zone Heating work?

In the zone heating system, an actuator opens and closes the valve based on the thermostat setting for that zone.
Each thermostat controls heating independently in order to heat different areas of the house. Zoned systems save energy by allowing homeowners to only heat the part of the home that they need, instead of the whole house.

For example, when one zone needs heating, that zone’s valves open, guiding the hot water to the radiators or in-floor pipes in that area of the home. When all zone valves aren’t calling for heat, the boiler turns off, saving energy.
