CONNECT:

The indicator lights and areas connected are corresponding. If you connect the thermostat to the corresponding indicator light, you need to connect the actuator to the corresponding area.

Product Description:

CCT-28-X Wireless Heating Controllers is used in water underfloor heating system. It can control zone valves, or boiler thermostats. As central control unit, it can also control boiler and circulating pump. According to user’s set temperature, controller can control to open or close boiler, circulating pump and electric actuators, to achieve the purpose of comfort and energy consumption saving.

Connect the thermostat:

Up to 8pcs BOT-R7X-NR and BOT-R6X-NR can be connected to 1pcs CCT-28-X.
Each zone can only be connected to one thermostat, but a thermostat can be connected to up to 8 zone.

How many rooms can one CCT-28-X control the temperature of at most?

A CCT-28-X can control the temperature of up to 8 rooms. If you want multiple rooms to have the same temperature, you only need one temperature controller connected to multiple zones on a CCT-28-X.
If you want to control different rooms separately, you need multiple temperature controllers to control different rooms separately.

Wiring diagram:

“N, L (INPUT).” connect the 220V AC power supply.
“COM, NO” connection to dry contact boiler (a small portion connected to COM, NC）
“Pump” connect to the water pump.
"ZONE 1-8" is connected to the normally closed actuator.
The thermostat is connected to each zone of CCT-28-X via RF.

Distance of thermostat controller:

The control distance of the thermostat can reach 30 meters when there is wall obstruction indoors
In the absence of obstruction outdoors, the control distance is 200m

The meaning of each indicator light:

LED11: Power indicator light. LED11 remains on when the device is powered on.
LED10: Boiler output indicator light. The light comes on when the boiler is heated, and goes off when the boiler is not heated
LED9: Water pump output light. When the circulation pump is working, the light comes on, and when the circulation pump stops working, the light goes out.
LED1-LED8: Temperature controller output indicator light. When the temperature controller shows heating, The LED light will light up; When the thermostat shows no heating, The LED light will turn off; When the thermostat is pairing, The LED light will flash.

Controlled by temperature controller:

The CCT-28-X and temperature controller are connected wirelessly through 433HZ.
The thermostat can be connected to a mobile phone, which controls the thermostat. The thermostat further sends signals to CCT-28-X to control the operation of the entire system.

Temperature controller power supply method:

BOT-R6X-WIFI-NR and BOT-R7X-WIFI-NR can both be powered by battery or USB.

Features of thermostat:

【Programmable】There are three programming modes, and multiple time periods of temperature can be set on weekdays.
【APP Control】Connect Tuya and the Smart Life App.
【Voice Control】Work with Alexa,Google Home,Alice.
【Child Lock】
【Anti-Freeze】

Actuator:

Type: Normally closed thermostat
