A thermostat is a control device used to control temperature. In a spa, it uses the set temperature (set point) that you determine as the target temperature that it keeps the water at.
For example, when you set the temperature to 38 Degrees, the thermostat controls the heating or cooling system to maintain 38 degrees.
There are three main parts to the thermostat:
The interface where you set the desired temperature set point. This can be a knob or a keypad as examples.
The sensing device. This is the way that the temperature of the water is determined.
The actuator. This is basically a switch, normal or electronic, that controls the heat, heat pump, gas heater or circulation pump when the water reaches or deviates from the set point.
