SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Follow all local electrical
codes during installation. All wiring must conform to local and national electrical
codes. Improper wiring or installation may damage thermostat.
Recognize safety information. This is the safety--alert symbol . When you see
this symbol on the equipment and in the instruction manual, be alert to the
potential for personal injury.
Understand the signal words DANGER,WARNING,andCAUTION.These
words are used with the safety--alert symbol. DANGER identifies the most
serious hazards which will result in severe personal injury or death. WARNING
4
signifies a hazard which could result in personal injury or death. CAUTION is
used to identify unsafe practices which may result in minor personal injury or
product and property damage. NOTE is used to highlight suggestions which will
result in enhanced installation, reliability, or operation.
INTRODUCTION
Carrier’s PTAC ComforttSeries non--programmable thermostat is a
wall--mounted, low--voltage thermostat which maintains room temperature by
controlling the operation of a heating and/or air conditioning system. Both heat
pump and air conditioner models are available. A variety of features are provided
including battery operation, memory in case of power interruption, separate
heating and cooling setpoints, backlighting, and built--in installer test.
This Installation Instruction guide and owners manual covers installation,
configuration, start up and operation of the PTAC specific Comfort Series line of
thermostats.
INSTALLATION CONSIDERATIONS
Models
There are two models for the PTAC Comfort Series non--programmable thermostat,
AC and HP versions. The model PTACSTAT--NP--HC--x is designed for AC
systems, controlling one stage of cooling and one stage of heating. It will not operate
a heat pump. Model PTACSTAT--NP--HP--x is designed for HP systems, controlling
one stage of cooling and two stages of heating. The HP thermostat model can be
converted to an AC unit. Select the appropriate model for the intended application.
Power
All Comfort Series models are dual powered. They can operate from batteries
(optional) or 24VAC power. Operation from 24VAC is preferred, if available.
5
Batteries
Battery operation is available for installations where there is no common (C)
wire available at the thermostat. For battery operation, install two alkaline AA
batteries. The thermostat is designed to operate up to one year on a set of
batteries. A battery indicator on the display warns when battery replacement is
needed. If batteries are installed and the thermostat is operated from 24VAC
power, battery operation will occur only when 24VAC power is not present. The
changeover between 24VAC power and battery power is automatic.
For HeatCool system, 5 wires are needed for 24VAC operation and 4 wires are
required for battery operation.
For HP system, 6 wires are needed for 24VAC operation and 5 wires for battery
operation.
When battery operation is used, the C terminal does not need to be connected.
NOTE: Batteries are not required when there are enough wires for proper
operation.
INSTALLATION
Mounting to a horizontal junction box.
For those installations requiring it, mounting hole locations for the
non--programmable are spaced to fit a horizontal junction box.
Step 1 — Thermostat Location
SApproximately 5 ft (1.5m) from floor.
SClose to or in a frequently used room, preferably on an inside
partitioning wall.
SOn a section of wall without pipes or duct work.
6
Thermostat should NOT be mounted
SClose to a window, on an outside wall, or next to a door leading to the
outside.
SExposed to direct light or heat from the sun, a lamp, fireplace, or other
temperature--radiating objects which could cause a false reading.
SClose to or in direct airflow from the unit.
SIn areas with poor air circulation, such as behind a door or in an
alcove.
Step 2 — Install Thermostat
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing thermostat, turn off all power to equipment.
There may be more than 1 power disconnect. Lock out and
tag switch with a suitable warning label.
!WARNING
1. Turn OFF all power to unit.
2. If an existing thermostat is being replaced:
a. Remove existing thermostat from wall.
b. Disconnect wires from existing thermostat, 1 at a time. Be careful not
to allow wires to fall back into the wall.
c. As each wire is disconnected, record wire color and terminal marking.
d. Discard or recycle old thermostat.
7
ENVIRONMENTAL HAZARD
Failure to follow this caution may result in environmental
damage.
Mercury is a hazardous waste. Federal regulations require that
Mercury be disposed of properly.
CAUTION
!
3. Open thermostat (mounting base) to expose mounting holes. The base
can be removed to simplify mounting. Press the thumb release at the top
of the thermostat and snap apart carefully to separate mounting base from
remainder of thermostat.
4. Route thermostat wires through large hole in mounting base. Level mounting
base against wall (for aesthetic value only—thermostat need not be level for
proper operation) and mark wall through 2 mounting holes. See Fig. 1.

5. Drill two 3/16--in. mounting holes in wall where marked.
6. Secure mounting base to wall with 2 anchors and screws provided
(additional anchoring holes available for more secure mounting, if
needed) making sure all wires extend through hole in mounting base.
7. Adjust length and routing of each wire to reach proper terminal and
connector block on mounting base with 1/4 in. of extra wire. Strip only
1/4 in. of insulation from each wire to prevent adjacent wires from
shorting together when connected. See Fig. 2.

8. Match and connect wires from the PTAC unit to proper terminals on the ther-
mostat connector blocks (see Fig. 3). Do not remove factory--installed jumper
wire from Rc and Rh terminals. The R wire from the PTAC can be connec-
ted to either position.

ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
Improper wiring or installation may damage the thermostat.
Check to make sure wiring is correct before proceeding with
installation or turning on unit.
CAUTION
!
9. Push any excess wire into wall and against mounting base. Seal hole in
wall to prevent air leaks. Leaks can affect operation.
10. Snap case back together. Attach thermostat to backplate by inserting tab
on bottom edge and hinging up until top snap secures. See Fig. 4.
