TSTATXXCNV10{ Thermostat Conversion Kit (4 to 5 Wire) — 10 Pack
* Do not use in zoning heat pump applications.
** Outdoor temperature sensor is an accessory for all Bryant 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 HybridHeatt (dual fuel) 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.
The outdoor air temperature sensor is included with the Thermidistat Control and HybridHeatt (dual fuel) thermostat.

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 using MotorMasterr
2. Compressor Start Assist -- Capacitor and Relay
Start capacitor and relay gives a ”hard” boost to compressor
motor at each start up.
Usage Guideline:
Required for reciprocating compressors in the
following applications:
Long line
Low ambient cooling
Hard shut off expansion valve on indoor coil
Liquid line solenoid 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.
3. 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.
4. 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.
Usage Guideline:
Required in low ambient cooling applications.
Required in long line applications.
Suggested in all commercial applications.
