INSTALLATION REQUIREMENTS
• Unpack and dispose of packaging materials.
• This thermostat is a wall mounted, low-volt-
age thermostat that maintains room tem-
perature by controlling the operation of the
PTAC/PTHP. Batteries are not required—
temperature and mode settings are pre-
served with the power off.
• This is not a 2-stage heat pump thermostat
with emergency heat selection. The PTAC/
PTHP turns on the electric heat automati-
cally based on the outdoor coil temperature,
which is influenced by the outdoor tempera-
ture and humidity conditions.
• Chassis must be installed before installing
remote thermostat.
IMPORTANT: Improper wiring or installation
may cause the thermostat not to function. Wir-
ing must conform to local and national electri-
cal codes.

REMOTE WALL THERMOSTAT INSTALLATION
LOCATION REQUIREMENTS
For best performance, thermostat should be
mounted:
• Approximately 5 ft (152.4 cm) from floor.
• Close to or in the room with the PTAC/PTHP,
preferably on an inside partitioning wall.
• On a section of wall without pipes or duct
work.
For best performance, do not mount thermo-
stat:
• Close to a window, on an outside wall, or
next to a door leading to the outside.
• Exposed to direct light and heat from a lamp,
the sun, a fireplace, or other heat source.
This may cause a false reading.
• Close to or in direct airflow from the PTAC/
PTHP.
• In areas with poor air circulation (behind a
door or in an alcove).

Replacing Existing Thermostat
1. Disconnect power to avoid product dam-
age during removal of existing thermostat.
2. Disconnect wires from existing thermo-
stat, one at a time. Do not allow wires to fall
back into the wall.
3. As each wire is disconnected, record wire
color and terminal marking.
4. Remove existing thermostat from wall.
5. See “Installing The New Thermostat.”
