Pressure switch and thermostat with two control outputs and two stages, operating in pressurization, depressurization, refrigeration, heating, or alarm modes. It can also be used for water level control. It is able to control two loads up to 1 HP directly and has two digital inputs that allow using external devices to protect the controlled system. The hourmeter stores the number of hours the compressor operates and indicates when the compressor needs servicing. By using temperature sensors together, it also monitors dynamic and adiabatic condensation, dynamic evaporation, superheating and subcooling, promoting greater energy efficiency in the system.
