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

Heattinstallations, 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. 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

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.

INSTALLATION

Carton contains the following components. See Fig. 2 for TP--PRH--A or Fig. 3

for TP--NRH--A.

Thermidistat Control Location

Thermidistat 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.

Thermidistat 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.

Install Thermidistat Control

ELECTRICAL OPERATION HAZARD

Failure to follow this warning could result in personal injury

or death.

Before installing Thermidistat Control, turn off all power to

equipment. There may be more than 1 power disconnect.
