Installer Configuration Menu
The thermostat controller comes from the factory with default settings for all configuration parameters. The UI
menu navigation and default settings are shown in Table 10. Before any outputs turn on, the controller must be
configured for the equipment connected. You need to start from the home screen to perform any of the following
tasks.

The current screen returns to the home screen if the current screen is not touched for 3 minutes.
Selecting Rooftop or Heat Pump Mode
By default, the thermostat controller is configured for Rooftop mode. This mode is used for up to two discrete
stages of heating (W1, W2) and up to two discrete stages of cooling (Y1, Y2). Certain heat pumps do not require an
O/B input and instead take standard W and Y commands as heat or cool commands, internally sequencing the
equipment. For these type of heat pump units, leave the controller in Rooftop mode.
When in heat pump mode, the TEC controls up to two stages of compressors (Y1, Y2) for both heating and cooling.
O/B is controlled through the W1/OB output and one stage of supplemental heat is controlled through the W2/SUP
output. To configure heat pump mode:
1.
Press the
Menu
icon.

and set appropriately for the O/B input on the equipment based on if the
equipment is normally cooling until the thermostat output is activated or normally heating (typically, Normally
Heat for O and Normally Cool for B).
