9. Push any excess wire into wall and against backplate.
Seal hole in wall to prevent air leaks. Leaks can affect
operation.
10. Attach thermostat to backplate by inserting tab on bottom
edge and hinging up until top snap secures.
11. Turn ON power to unit.
When power is applied, all display icons are lit for 2 sec-
onds to test the display. Following this, the equipment type for
which the thermostat is configured is displayed for an addition-
al 2 seconds. Equipment type will be either HP, AC, H, C or 35
(for WSHP) (for explanation see Option 01 below).
NOTE: If a common wire has not been connected, two AA
batteries must be used to power the thermostat.
CONFIGURATION
Configuration options enable the installer to configure the
thermostat for a particular installation. These configuration op-
tions are stored to the internal memory so they are retained
through a power outage. The availability of some configuration
options will be dependent upon other conditions in the thermo-
stat. For example, the backlight configuration is not available
unless full 24 vac power is connected. See Table 1.

Configuration Options
OPTION 01 — EQUIPMENT TYPE — This option deter-
mines the control method of the thermostat. It should match the
type of equipment used.
OPTION 02 — REMOTE SENSOR SELECTION — A re-
mote thermistor can be connected to the S1 and S2 screw ter-
minals to sense either remote space, outdoor air, supply or re-
turn air temperature.
NOTE: Carrier sensors 33ZCT55SPT, 33ZCSENDAT,
33ZCSENSAT, and 33ZCSENOAT may be used for standard
space temperature sensor averaging. Sensors must be used as a
single sensor, 4 sensors or 9 sensors, with total sensor wiring
not to exceed 1,000 ft.
OPTION 03 — ENGLISH/METRIC — This configuration
selects between Fahrenheit (F) and Celsius (C) operation.
OPTION 04 — FAN (G) ON WITH W OUTPUT — This
configuration is not available if the thermostat is configured as
Cool Only in Option 01. This selection determines whether fan
(G) output is to be on or off when the W is energized in AC,
HP, H or 35 (WSHP) configurations, and when the O/B output
is energized in the AC or H (heat only) configurations.
OPTION 05 — SPACE TEMPERATURE SENSING —
This selection determines which sensor the control will use for
measuring space temperature. Space temperature can be
