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 Edge Thermidistat 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’ Go settings
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
Heat 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.

WARNING
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.
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.
6
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
Wire length should be no more than 250 ft (76 m). Use 22 AWG or larger for
normal wiring applications. Continuous wire lengths over 100 ft (30.5 m) should
use 20 AWG or larger.
