TEMPERATURE SWING
A thermostat works by turning your heating or cooling system on and off whenever the room
temperature varies a certain number of degrees from the set-point temperature. This variation is the
“swing.”
Your system should cycle on about 3 to 6 times per hour. A smaller swing number increases the
number of cycles, so room temperature is more constant. A larger swing number decreases the
number of cycles, to save energy in most cases.

To protect your home from freezing in the event you have inadvertently left the unit switched OFF,
or its batteries have been drained, your PSPH521 will energize the thermostat’s heating
terminals as necessary to control the temperature at approximately 40°F. Please call our technical
assistance department if your application requires that this feature be disabled.
