INTRODUCTION
The Base 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 ma/-- 2
_
F accuracy. No batteries are required;
temperature, fan, mode, and installer configuration settings are
preserved with power off.
INSTALLATION CONSIDERATIONS
Universal Model
The P700U--21NHP Base thermostat may be configured for either
AC models or HP models. When configured as an AC model, it
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.
When configured for HP units, 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.
