In summer, plug your cooling fan in the socket COOL (FAN) and adjust room temperature controller to required temperature, say 20C. If the room temperature is up to 20C or above, the electric fan which is plugged into the socket COOL (FAN) outlet on the Thermal Controller unit will be automatically switched on. When the room temperature is dropped below 20C, the fan will be automatically stopped!
The stainless steel temperature sensor pole should be always kept away from the cooling device, and measures external free air and room temperature.
In winter, plug your heating device in the socket WARM (HEATER) and adjust room temperature controller to required temperature, say 20C. If the room temperature is below 20C, the electric heater which is plugged into socket WARM (HEATER) outlet on the Thermal Controller unit will be automatically switched on.
