Smart WIFI Thermostat for Water Floor Heating System - Gas Boiler Controller

**Product Description:**

Introducing the CCT-25/CCT-28, a smart multi-zone heating system controller designed specifically for water floor heating setups, including connections to gas boiler systems. This advanced 5/8-channel thermostat controller features clear indicators and is engineered to manage multiple zones efficiently.

The CCT-25/CCT-28 centralizes the processing of water floor heating signals, allowing for precise control over the opening and closing of floor heating electric valves. It also facilitates zone control by managing electric actuators, ensuring that the heating elements work in harmony with the heat pump, boiler, and external water pump (mixing center).

The CCT-25 and CCT-28 are compatible only with water heating controllers and normally closed actuators, providing intelligent control for heating, not cooling. It operates through a connected Wi-Fi model, enabling you to manage your heating system remotely.

**How Zone Heating Works:**

In a zone heating system, each actuator is controlled by its corresponding thermostat, which adjusts the heating based on the desired temperature for that specific area. This setup allows homeowners to heat only the sections of the home that require warmth, thus optimizing energy consumption.

For example, when the thermostat in one zone signals for heat, the associated valves open, directing hot water to the radiators or in-floor pipes within that zone. If no zones require heat, the boiler shuts off, which conserves energy.

**Differences Between CCT-25 and CCT-28:**

- **CCT-25:** Connects up to 5 temperature controllers, with one thermostat per zone valve and up to 3 NC actuators per zone.

- **CCT-28:** Connects up to 8 temperature controllers, maintaining the same configuration for zone valves and actuators.

**Normally Closed Actuator:**

The normally closed actuator gradually opens based on the temperature controller’s signals, modulating the water flow accordingly. Once the indoor temperature reaches the set level, the boiler ceases heating, and the actuator slowly closes to halt the water flow.

**Application:** Ideal for water manifold heating systems, featuring an M30 x 1.5 connection ring and a power consumption of only 2W, this controller is an essential addition for effective and energy-efficient heating management in your home.
