BOT-R6X-NR and BOT-R7X-NR: Only the controller, no receiver, pay attention to the model before purchasing.
Product Description:
CCT-28-X Wireless Thermostat Controllers are used in water underfloor heating systems. It can control zone valves or boiler thermostats. As a central control unit, it can also control the boiler and circulating pump. According to the user’s set temperature, the Heating controller can control to opening or closing of the boiler, circulating pump, and electric actuators, to achieve the purpose of comfort and energy consumption.
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 zones.
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.
How many actuators can be connected to a zone?
CCT-28-X can only connect normally closed actuators, and a maximum of 8 normally closed actuators can be connected in one zone.
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” connects 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 paired, The LED light will flash.
