Final answer:
Thermostats and pressure sensors are automatic controls that can maintain condenser temperature.
Step-by-step explanation:
The types of automatic controls that can maintain condenser temperature are thermostats and pressure sensors.
A thermostat is a device that senses the temperature of the condenser and can automatically adjust the operation of the compressor to maintain a desired temperature. For example, if the condenser temperature goes above a set limit, the thermostat can signal the compressor to increase its cooling capacity.
A pressure sensor is another type of automatic control that can maintain condenser temperature. It measures the pressure of the refrigerant in the condenser and can adjust the operation of the compressor accordingly. If the pressure gets too high, the pressure sensor can signal the compressor to reduce its cooling capacity.
