SPECIAL INSTRUCTIONS FOR DUAL FUEL APPLICATIONS

When the T-32-P is used with dual fuel systems, an outdoor sensor is recommended for balance
point control (Model T-32-S1). The sensor is wired to the TT terminals on the thermostat. In the

default low balance point setting. High balance point is adjustable from OFF to 32° F - 122° F and low
balance point is adjustable from OFF to 14° F - 77° F. When the outdoor temperature rises above the
high balance point setting, only first stage heat pump will be allowed to energize. When the outdoor
temperature falls below the low balance point setting, only the auxiliary heat will be energized and the
heat pump will be locked out. Typical settings might be 30° F Low Balance Point and 55° F High
Balance Point. High and low balance point control can also be used in conventional heat pump
applications.
The high balance point must be greater than the low balance point and there should be at
least a 5° F spread between the two.

ACTIVATING THE BATTERY

The T-32-P contains a 3 volt Lithium cell battery that maintains
the time of day in the event of a power failure. To activate the
battery, carefully remove the white tab. (Figure 4)

SETTING THE SYSTEM SWITCHES

The T-32-P contains a set of eight system switches located on
the thermostat printed circuit board. The switches are used to
match the thermostat with the specific type of HVAC system and
user preferences. Refer to the system switch functions to
properly configure the thermostat. (Figure 5)
