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