Operation

Setup/Operation of the T600HPx-4 or
T600HPx-4+PIR Series Thermostat Controller
Once the thermostat controller is configured via the
Installer Configuration Menu, set up its operating
parameters via the Main User Menu. Access this menu
by pressing the MENU key during normal thermostat
controller operation. The Main User Menu contains the
basic operating features of the thermostat controller.
The Main User Menu also uses Auto Help, which is
displayed automatically in the menu when there is a
pause in setup activity. To exit Auto Help, continue with
the setup selection. When the thermostat controller is
in the Main User Menu and is left unattended for
45 seconds, the menu reverts to the Status Display
Menu.
Follow the steps in Table 3 to set up the thermostat
controller.
T600HPx-4 and T600HPx-4+PIR Series Heat Pump Thermostat Controllers Installation Instructions
Selection Options
(on): In the heating mode only. If the heat pump is not able to satisfy
the heating setpoint, the auxiliary heat is energized and the heat
pump is shut off. This typically applies when the air handler heat
pump coil is installed after the auxiliary heat. There is a 2-minute
delay to restart the heat pump after the auxiliary heat is shut down.
(off): In the heating mode only. If the heat pump is not able to satisfy
the heating setpoint, the auxiliary heat is energized at the same time
as the heat pump stage. This typically applies when the air handler
heat pump coil is installed before the auxiliary heat (all electric
systems).
