INTRODUCTION
Carrier’s 7--day, 5/2--day, 1--day programmable and non--programmable
Performance Series Thermostat Control is a wall--mounted, low--voltage control
which combines temperature and humidity control in either a single unit or a
two--piece unit. In two--piece configuration, the relays are located near the
equipment and a two--wire connection is used between the Display Module and
the Equipment Control Module. Single--piece installation requires more wiring
and results in a higher profile. The EdgetThermostat has no need for batteries
to store user--configured settings in memory. During power loss its internal
memory saves settings for unlimited time, and the clock continues to run for at
least 24 hours. An extension of Carrier’s proven line of thermostats; it provides
separate setpoints for heating and cooling in addition to humidification and
dehumidification.
In the Edge Thermostat Control’s programmable configuration, different heating
and cooling setpoints and times are programmable for 4 periods per day or 2
periods per day. Programming can be done for 7 days per week, 5/2 days per
week, or 1 day. The programmable Thermostat Control can also be user
configured as a non--programmable Thermostat Control. When operating as
non--programmable, the Edge Thermostat Control will still have both
temperature and humidity control.
The non--programmable Thermostat Control features Touch ’N’ Gotsettings
for quick and easy temperature change without complicated programming
schedules. The non--programmable Edge Thermostat Control will still have both
temperature and humidity control. And, its Touch ’N’ Go technology enables the
user to switch between three different user--configurable settings through
intuitive buttons located just below the display.

INSTALLATION CONSIDERATIONS
Power
This control is powered by 24VAC only. It requires 24VAC (Rh and/or Rc and C
terminals) of the low--voltage transformer to be connected to it for proper
operation. It will not operate without these 2 connections. Rh and Rc are
connected via PCB breakout jumper. See Fig. 1. For applications using two
24VAC transformers, one in the indoor unit and one in the outdoor unit, connect
the common from each to the C terminal. Connect R from the indoor unit to the
Rh terminal. Connect R from the outdoor unit to the Rc terminal. Then, break
jumper on the circuit board. The W and HUM signals are taken from the Rh
power and the G signal is taken from the Rc power. If Thermidistat Control has
been installed in a two--transformer application that is later changed to a
single--transformer installation, installer must install a field supplied jumper
between Rc and Rh. Depending on the installation, up to 14 wires may be
required. Installation as two--piece unit is recommended. Only 2 wires are
required for connection between Display Module and Equipment Control
Module. These two wires (V+ and Vg) do not provide ordinary 24VAC. They
carry a combination of power and communications data that is unique to these
products.

Models
There are programmable and non--programmable models for all applications.
They can be configured for AC or HP installations, allowing it to be used in
place of all Carrier thermostats. Programmable thermostats may be configured as
non--programmable if user desires.
Outdoor Temperature Sensor
The outdoor air temperature sensor is not included with the AC/HP Control. It is
available as an accessory, part number TSTATCCSEN01--B. Optimum
performance is obtained when an outdoor temperature sensor is used with the
AC/HP Control. Plan installation so that 2 wires can be run from Equipment
Control Module to an outdoor location, preferably on the north side of the house
or refer to Installation Instructions included with the outdoor temperature sensor
for simplified connection. Sensor can be mounted to outdoor unit and existing

6
dedicated sensor wires may be used for its connection. Details are provided in
sensor instructions.
Remote Indoor Temperature Sensor
A remote temperature sensor may be used with the programmable heat pump
and programmable air conditioner thermostats where it is desirable to install the
thermostat in a limited access location while measuring the temperature in the
living space. The remote room sensor may be used as a stand alone or average
with local sensor.
Two--Piece Thermostat Configuration
The Performance Series AC/HP Control can be installed in one of two
configurations. The control may be installed as a single--piece thermostat or it
may be split into two pieces and mounted in separate locations. As a single--piece
unit, all required wiring must be brought to the Equipment Control Module for
connection to the terminal strip. In two--piece configuration, the Display Module
can be mounted in the living space while the Equipment Control Module may be
mounted near the indoor furnace or fan coil. Connection from the display to the
Equipment Control Module requires only two wires. All other control wires are
connected to the Equipment Control Module from the HVAC equipment. This
configuration results in a slimmer display and locates the Equipment Control
Module containing the switching relays away from the main living space where
relay clicking will not be heard.

AC/HP Control Location
AC/HP Control should be mounted:
SApproximately 5 ft (1.5m) from floor.
SClose to or in a frequently used room, preferably on an inside parti-
tioning wall.
SOn a section of wall without pipes or duct work.

9
AC/HP Control should NOT be mounted:
SClose to a window, on an outside wall, or next to a door leading to the
outside.
SExposed to direct light or heat from a lamp, sun, fireplace, or other
temperature--radiating objects which could cause a false reading.
SClose to or in direct airflow from supply registers and return--air regis-
ters.
SIn areas with poor air circulation, such as behind a door or in an al-
cove.
Installer should determine whether control will be installed as single--piece or
two--piece. In single--piece configuration, as many as 14 wires may need to run
to wall mounting location for connection to the control. In two--piece
configuration, the Display Module and Equipment Control Module are
connected by two wires.
