Carrier PTACSTAT-NP-HP Installation & Operating Manual page 17

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
off
cool
heat
Em Heat (HP only)
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.
Checklist
1. Run equipment through several heating and cooling cycles to ensure
