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
MUST have both the R and C terminals connected to operate

properly. This thermostat uses a green LED to indicate auxiliary
heat and emergency heat operation.

INSTALLATION

Step 1 — Thermostat Location

Thermostat should be mounted:

S

Approximately 5 ft (1.5m) from floor.

S

Close to or in a frequently used room, preferably on an
inside partitioning wall.

S

On a section of wall without pipes or duct work.

Thermostat should NOT be mounted:

S

Close to a window, on an outside wall, or next to a door
leading to the outside.

S

Exposed to direct light and heat from the sun, a lamp,
fireplace, or other heat--radiating object which may cause

a false reading.
