It acts as a thermostat by sensing temperature, therefore, when the set temperature is too high, it turns on heating or cooling equipment. It has great flexibility of operation in terms of temperature working between 100°F to 240°F and it can be widely used in industrial heating and cooling. The remote bulb, which is connected to the control by a 20” capillary tube, is placed where the temperature is to be controlled. The control unit has a temperature sensor that receives temperature from the remote bulb. The control unit turns on or off the equipments connected to the HVAC as soon as the unit notices an increase or decrease in temperature so that it can achieve the optimum temperature.
