SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Follow all local electrical
codes during installation. All wiring must conform to local and national electrical
codes. Improper wiring or installation may damage Thermidistat Control.
Recognize safety information. This is the safety-alert symbol . When you see
this symbol on the equipment and in the instruction manual, be alert to the potential
for personal injury.
Understand the signal words DANGER,WARNING,andCAUTION.These
words are used with the safety- alert symbol. DANGER identifies the most serious
hazards which will result in severe personal injury or death. WARNING signifies a
hazard which could result in personal injury or death. CAUTION is used to identify
unsafe practices which may result in minor personal injury or product and property
damage. NOTE is used to highlight suggestions which will result in enhanced
installation, reliability, or operation.

INTRODUCTION
Carrier’s 7- day, 5/2- day, 1- day programmable and non- programmable
Performance Series Thermidistat 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 EdgerThermidistat 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 Thermidistat Control 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 Thermidistat Control can also be user configured as a
non- programmable Thermidistat Control. When operating as non- programmable,
the Edge Thermidistat Control will still have both temperature and humidity
control.
The non- programmable Thermidistat Control features Touch ’N’ Gotsettings for
quick and easy temperature change without complicated programming schedules.
The non-programmable Edge Thermidistat 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, 1- or 2- speed compressor, and for Hybrid Heatt
installations, allowing it to be used in place of all Carrier thermostats.
Programmable Thermidistat Controls may be configured as non- programmable if
user desires.
Humidify Equipment and Connections
The humidify output connects directly to 24VAC operated humidifiers. An isolation
relay may be required when using powered humidifiers. No other connection or
interlock is required. Any of several installer- selectable operating modes are
available.

ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or death.
DO NOT connect furnace HUM terminal directly to Thermidistat
Control HUM terminal. This will bypass furnace safety controls. See
Low Voltage Wiring Diagrams and notes for proper connection.
!WARNING
Dehumidify Equipment and Connections
The dry contact output connects to the dehumidify input on variable- speed
furnaces and fan coils. Additional dehumidification is done by controlling the
compressor. A variety of operating modes are available. The dry contact must be
configured for dehumidification in setup Option 19. See Wiring Diagrams for more
information.
Outdoor Temperature Sensor (TSTATCCSEN01- B)
Outdoor air temperature sensor is included in the box with the Thermidistat Control.
Optimum performance is obtained when an outdoor temperature sensor is used with
the Thermidistat 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 control 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 model, where it
is desirable to install the Thermidistat Control 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 Thermidistat Control Configuration
The Performance Series Thermidistat Control can be installed in one of two
configurations. The control may be installed as a single- piece Thermidistat Control
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
Module 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.
The model numbers on the Display Module and the Equipment Control Module
(ECM) must match or unpredictable results may occur.
Two-wire pigtail replacement part number is TX- 2WR05.
Wiring
For all wiring applications, use 22 AWG or larger wire. Continuous wire lengths
over 100 ft. (30.5 m) should use 20 AWG or larger. Wire lengths are not to exceed
250ft.(76m)perrun.

INSTALLATION
UNIT DAMAGE HAZARD
Failure to follow the recommended wiring practices could result in
damage to the wall control and personal property.
Improper wiring or installation may damage Thermidistat Control.
Check to make sure wiring is correct before proceeding with
installation or turning on power.
CAUTION
!
Installation Notes:
SNo part of the control should be installed directly outdoors or in a cabin-
et outdoors.
SNever remove the thermostat board from the plastic housing. Doing so
could warp and damage the components on the board.
SThe control assembly should be mounted before wires are attached.
SDuring thermostat installation, provide sufficient excess wiring behind
the mounting plate. Coil the wiring, creating a service loop, and place in
mounting box or behind the wall to remove strain against the terminal
strip. See Fig. 2.
