* Do not use in zoning heat pump applications.

† This plate is designed to cover surrounding wall area located behind thermostat.

‡ Thermostat conversion kit is a 24-vac accessory that can turn a 4-wire thermostat application into a 5-wire application. This kit can also be used to replace

a broken thermostat wire, or add an extra wire when needed.

** Outdoor temperature sensor is an accessory for all Carrier electronic thermostats, except the non-programmable air conditioner version and builder's

thermostats. It allows the temperature at a remote location (outdoors) to be displayed on the thermostat.

The outdoor air temperature sensor must be used with the dual fuel thermostat.

The outdoor air temperature sensor is included with the Thermidistat Control and dual fuel thermostat.

Accessory usage guideline

ACCESSORY

Crankcase Heater

Evaporator Freeze Thermostat

Compressor Start Assist — Capacitor and Relay

Puron Low Ambient Pressure Switch

Wind Bafﬂe

Support Feet

Puron Hard Shutoff TXV

Puron Liquid-Line Solenoid Valve for Heating

* For tubing line sets between 50 and 175 ft and/or 20 ft elevation difference between indoor and outdoor units, refer to the Application Guideline and Service Man-

ual—Air Conditioners and Heat Pumps Using Puron® Refrigerant.

† Required for all applications.

Accessory description and usage (Listed alphabetically)

1. Ball-Bearing Fan Motor

A fan motor with ball bearings which permits speed reduction while maintaining bearing lubrication.

Usage Guideline:

Required on all units when MotorMaster®—Low-Ambient Controller is installed.

2. Coastal Filter

A mesh screen inserted under the top cover and inside the base pan to protect the condenser coil from salt damage without restricting airflow.

3. Compressor Start Assist – Capacitor and Relay

Start capacitor and relay gives a "hard" boost to compressor motor at each start up.

Note:

Heat pumps with Puron-refrigerant and a reciprocating compressor have capacitor and relay factory supplied.

Usage Guideline:

Required for single-phase reciprocating compressors in the following applications:

Long line

Low ambient cooling

Hard shut off expansion valve on indoor coil

Required for single-phase scroll compressors in the following applications:

Long line

Low ambient cooling

Suggested for all compressors in areas with a history of low voltage problems.

4. Compressor Start Assist — PTC Type

Solid state electrical device which gives a "soft" boost to the compressor at each start-up.

Usage Guideline:

Suggested in installations with marginal power supply.

5. Crankcase Heater

An electric resistance heater which mounts to the base of the compressor to keep the lubricant warm during off cycles. Improves compressor lubrication on

restart and minimizes the chance of liquid slugging.

Note:

Some heat pumps are factory supplied with a crankcase heater. See accessory list for units that come standard with a crankcase heater. For units that do

not, use the guideline below.

Usage Guideline:

Required in low ambient cooling applications.

Required in long line applications.

Suggested in all commercial applications.
