Setting Thermostat User Options
The default user options are compatible with most systems and applications. They are normally
set at the time of installation and usually do not require modification under normal operating
conditions. If you desire to change these settings, simply follow the instructions below.
NOTE: The temperature differential settings are the same for both the heating and
cooling systems.
The default setting is 0.5˚ F (0.25˚ C). The room temperature must change 0.5˚ F (0.25˚ C) from
the setpoint temperature before the thermostat will initiate the system in heating or cooling.
NOTE: Once you have finished setting the temperature differential you can wait 15
seconds and the thermostat will automatically return to the normal operation mode.
Otherwise, you can press the RETURN button again to set the Residual Cooling Fan Delay.
