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 Edger 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’ Got 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 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.

!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.
