INTRODUCTION
The Base Series thermostat is an electronic 24VAC,
non--programmable, manual changeover wall mount thermostat.
This thermostat uses a single setpoint to maintain and control room
temperature in both the heating and air conditioning modes. The
thermostat is designed to maintain +/-- 2_F accuracy. No batteries
are required; temperature, fan, mode, and installer configuration
settings are preserved with power off.
INSTALLATION CONSIDERATIONS
Air Conditioner Model
TB--NAC, Base Series Model air conditioner thermostat, may be
wired with or without connecting a common wire between the
indoor equipment and the thermostat. However, it is recommended
to use a common wire whenever possible. Without a common wire
this thermostat becomes “power stealing.” This means it will need
to steal a small amount of power from the equipment to which it is
connected.
NOTE: Not all HVAC equipment is compatible with power
stealing type thermostats. All Carrier equipment is directly
compatible with this thermostat except the Thermostat Conversion
Kit, Part #TSTATXXCNV10. For all non--Carrier equipment,
consult the system equipment Installation Instructions before
applying this thermostat in a power stealing manner.
Heat Pump Model
TB--NHP, Base Series Model heat pump thermostat, is compatible
with all Carrier heat pump systems. It is NOT power stealing and
