When the thermostat controller is in the Installer
Configuration Menu and left unattended for
approximately 8 seconds, the thermostat controller
reverts to the Status Display Menu.
Configuring Inputs BI1, BI2, and UI3
When BI1 and BI2 are configured for an alarm
condition, an alarm condition displays locally when the
input closes. An alarm message is included on the
scrolling Status Display Menu and when the message
is displayed, the backlight momentarily lights up.

Configuring the Sequence of Operation
(SeqOpera)
Choose the appropriate sequence of operation. The
modes presented are user-dependent on the sequence
of operation selected. For two-pipe applications using a
changeover sensor, choose the selection option
(0): Cooling Only. Changeover occurs between
Cooling Only and Heating Only. See Figure 16
through Figure 21 for sequence of operation examples.
