In a cooling tower, the cooling fan runs for hours without any stops. Even when the cooling is achieved, it remains ON. So, there is more consumption of electricity which could be saved by using this energy saver.
The energy saver stops the fan when effective cooling is achieved. The fan starts again when the temperature gradually starts increasing above (SET+HYS) and if the time delay is over. It will start again if any of the two conditions are not fulfilled.
There is an in built ON delay timer that allows us to avoid instant start of motor. As long as the safety timer remains ON, the last digit of the temperature display will blink.
A time totalizer is provided that will allow you to record the total OFF or ON hours of the fan.
