Bryant T2-PAC installation instructions Check Thermostat Operation

Step 4 — Check Thermostat Operation

The Legacy Series thermostats have a built-in installer test capability. Use it to check thermostat and equipment operation without delays or setpoint adjustments to force heating or cooling.

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 St on the right for the programmable model, or InS in the smaller display for the non-programmable model. The MODE will be OFF. The MODE key (upper left) can now be used to select heat, cool, or emergency heat, if this is a HP thermostat. Selecting one of the available modes will immediately command the equipment to turn on in that mode. It will run for 3 minutes and then return the mode to off. With HP thermostats (having 2 stages of heating), the test will run for 3 minutes on each stage. If the thermostat is programmable, the clock display counts down from 180 seconds while each stage operates. 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
off	off
cool	cool on
heat	heat on, aux heat on
Em Heat	aux heat on

To terminate the Installer Test mode press the DONE or FAN button. If the thermostat is left in Installer Test mode, it will revert back to normal operation after 15 minutes.
