To enter the Installer Test mode, use the same process as is used to enter Installer Configuration, only hold the FAN key longer. More specifically, press and hold the FAN for about 15 seconds until the display reads In on the left and S in the smaller display. The MODE will be OFF. The MODE key (upper left) can now be used to select heat, cool, or emergency heat (HP only). Selecting one of the available modes will immediately command the equipment to turn on in that mode. The request will stay active for 3 minutes and then return the mode to off. With HeatPump thermostats (having 2 stages of heating), the request will be active for 3 minutes on each stage.

Changing the mode to OFF will terminate any running test immediately.

During any test, the display icons will be displayed the same as for normal operation of that stage, as follows:

SELECTED MODE

DISPLAY ICONS

To terminate the Installer Test mode, press the up or down temperature buttons. If the thermostat is left in Installer Test mode, it will revert back to normal operation after 15 minutes.
