Programmable Thermostat - Carrier 52S Architects And Engineers' Manual

ORDERING DATA (cont)

Programmable Thermostat

Part No.: TSTATCCPAC01-B (for heat/cool models)
Part No.: TSTATCCPHP01-B (for heat pump models)
This microcomputer-controlled, programmable wall
thermostat has enhanced features that provide auto-
matic changeover control for both heat pumps and
heating/ cooling units. It is used only on wall thermo-
stat control (RC) models.
NOTE: Be sure to connect reversing valve wiring to
the B connection of the thermostat for heat pump
applications.
Replacement Filters
Part No.: AIR-FILTER-25PK
The Carrier 52S model replacement air filters come in
packages of 25. The filters save energy by preventing
the evaporator coils from being plugged with dirt and
lint. These economical and sturdy mesh filters may be
washed, vacuumed, and reused. Carrier's filters meet
original equipment specifications and are factory-
authorized replacement parts.
Energy Management Kit
Part No.: EM-KIT
This field-installed accessory kit allows individual
units to be turned on and off from a remote location.
When installed at a hotel front desk, the kit can help to
conserve energy by allowing hotel staff to easily turn
off units when rooms are not occupied.
The kit incorporates Carrier's Freeze Guard protection
that prevents rooms from freezing during extreme or
extended cold periods. Under these conditions, the
Freeze Guard automatically disables front desk control
and allows the unit to maintain a temperature of at
least 50 F in the room. When the room reaches 65 F,
the Freeze Guard feature returns the unit control to the
front desk.
This kit interfaces to most energy management sys-
tems. When installed in locations other than the front
desk, the kit can control unit operation by receiving
signals from field-supplied devices such as motion
sensors or heat sensing detectors.

Easily Replaceable Filters
Energy Management Kit
Control devices connected to the Energy Management
Kit must have normally open sets of contacts (when
the switch is open, the unit operates). A 24-volt trans-
former must be field supplied and connected to the
Energy Management Kit. (See typical wiring diagram
on page 40.)
