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 pro

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 term

A07052 Fig. 1 − PCB Breakout Jumper 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 re

! 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 compress

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 singl

Exposed to direct light or heat from a lamp, sun, fireplace, or other temperature −radiating objects which could cause a false reading. Close to or in direct airflow from supply registers and return −air registers. In areas with poor air circulation, such as behind a door or in an alcove. 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

! CAUTION UNIT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. Improper wiring or installation may damage Thermidistat Control. Check to make sure wiring is correct before proceeding with installation or turning on power. 1. Turn off all power to equipment. 2. If an existing Thermidistat Control or thermostat is being replaced: a. Remove existing control from wall. b. Disconnect wires from existing thermostat, 1 at a time. c. As each wire is dis

! CAUTION ENVIRONMENTAL HAZARD Failure to follow this caution may result in environmental damage. Mercury is a hazardous waste. Federal regulations require that Mercury be disposed of properly. Two −Piece Installation The following steps should be followed for the installation of the two −piece configuration. NOTE: The 2 −wire pigtail is not intended to support the weight of the Display Module. Do not hang the Display Module from the Equipment Control Module screw terminals. 1. Remove mounting

2. Route wires through large hole in mounting base. Level mounting base against wall (for aesthetic value only—Display Module need not be leveled for proper operation) and mark wall through 4 mounting holes. To avoid unintended bending of wall plate plastic, use all 4 screws and anchors. See Fig. 6. A07165 Fig. 6 − Backplate Mounting 3. Drill four 3/16 −in. mounting holes in wall where marked. Thermidistat Control may be mounted to a standard junction box, if desired. Hole pattern on Thermidista

6. Match and connect equipment wires to proper terminals of each connector block, being careful not to over tighten the screws. Correct polarity must be observed when connecting the two wires from the Equipment Control Module to the Thermidistat Control mounting base. If wires are connected incorrectly, the Display Module will not operate. See Fig. 7, 8 and 9. A08072 Fig. 7 − Control Module Wiring Guide Red is V+ Black is Vg 15
