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 AC/HP 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, and CAUTION. 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 Thermostat Control is a wall-mounted, low- voltage temperature 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 Edget Thermostat 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 the Edge Thermostat 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 Thermostat Control can also be user configured as a non- programmable Thermostat Control. The non-programmable Thermostat Control features Touch ’N’ Got settings for quick and easy temperature change without complicated programming schedules. 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

INSTALLATION

Installation Notes:

Step 1 — Thermostat Location

The thermostat should NOT be mounted

Step 2— Install the Thermostat!

WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or death.
Before installing thermostat, turn off all power to equipment. There may be more than one power disconnect.

  1. Turn OFF all power to unit.
  2. If an existing thermostat is being replaced:
    • Remove existing thermostat from wall.
    • Disconnect wires from existing thermostat, one at a time. Be careful not to allow wires to fall back into the wall.
    • As each wire is disconnected, record wire color and terminal marking.
    • Discard or recycle old thermostats.
      ! 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.
  3. Open thermostat (mounting base) to expose mounting holes. The base can be removed to simplify mounting. Press the thumb release at the top of the thermostat and snap apart carefully to separate mounting base from remainder
    of thermostat.
  4. Route thermostat wires through large hole in mounting base. Level mounting base against wall (for aesthetic value only—thermostat need not be level for proper operation) and mark wall through four mounting holes. To avoid unintended bending of wall plate plastic, all four screws and anchors must be used. See Fig. 1.Carrier-TC-PAC-Non-Programmable-Thermostat-fig.1
  5. Drill four 3/16–in. mounting holes in wall where marked.
  6. Secure mounting base to wall with four screws and anchors provided. To avoid unintended bending of wall plate plastic, all four screws and anchors must be used. Make sure all wires extend through hole in mounting base.
  7. Adjust length and routing of each wire to reach proper terminal and connector block on mounting base with 1/4–in. (6 mm) of extra wire. Strip only 1/4 in. of insulation from each wire to prevent adjacent wires from shorting together when connected. See Fig. 2.Carrier-TC-PAC-Non-Programmable-Thermostat-fig.2
  8. Match and connect equipment wires to proper terminals of the connector blocks (see Fig. 3). If there are separate 24VAC transformers, one in the indoor unit and one in the outdoor unit, connect the common of each to the C terminal. Remove factory–installed jumper wire from Rc and Rh terminals. Connect the R from the indoor unit to the Rh terminal. Connect the R from the outdoor unit to the Rc terminal. Then the W signal is taken from the Rh power and the Y1, Y/Y2, G and O signals are taken from the Rc power.Carrier-TC-PAC-Non-Programmable-Thermostat-fig.3
    CAUTION
    ELECTRICAL OPERATION HAZARD
    Failure to follow this caution may result in equipment damage or improper operation.
    Improper wiring or installation may damage the thermostat. Check to make sure wiring is correct before proceeding with installation or turning on unit.
  9. Push any excess wire into wall and against mounting base. Seal hole in wall to prevent air leaks. Leaks can affect operation.
  10. Snap case back together. Attach thermostat to backplate by inserting tab on bottom edge and hinging up until top snap secures. See Fig. 4.Carrier-TC-PAC-Non-Programmable-Thermostat-fig.4
  11. Close thermostat assembly making sure pins on back of circuit board align with sockets in connector.
  12. Turn ON power to unit.
    When power is applied, all display icons are lit for 2 seconds to test the display. Following this, the equipment type for which the thermostat is configured is displayed for an additional 2 seconds. It will be one of HP, H2, AC, A2, H or C (see explanation under Step 3, Option 01 below). A HP thermostat configured to operate an AC (see Option 1 below) will display AC. An AC thermostat cannot display HP.
    NOTE: If a common wire has not been connected, two AA batteries must be used to power the thermostat.

Step 3 — Set Thermostat Configuration

Configuration options enable the installer to configure the thermostat for a particular installation. Most are not presented to the homeowner and therefore must be properly set by the installer. (Only those marked with an asterisk * below are available to the homeowner.) Following is a list of the options available, an explanation of their function, and their factory default settings. Not all numbers are used in the Comfort Series
because not all options are available in this series — and numbering is consistent across
the TB, TC, and TP thermostat lines.
Configuration Options — Summary:

To Enter the configuration mode:

Press and hold the FAN key for about 10 seconds until the display changes so that only two pairs of digits are showing. The left (programmable version) or the large upper (non–programmable version) display shows the configuration number and the right (programmable version) or small lower (non–programmable version) shows the configuration setting. Configuration number will be flashing which means it can be adjusted using the UP and DOWN keys. To cause the opposite pair to flash (to be adjustable), press the MODE key. Successive presses of the MODE key alternate between the configuration number and the configuration setting. To exit the configuration mode, press the FAN key. If no key is pressed for 3 minutes, the configuration mode will automatically exit, returning the thermostat to normal operation.
Configuration Options — Selection:

  1. Option 01 — Equipment type Selections: with HP thermostat: HP, H2, AC, A2, H, C with AC thermostat: AC, H, C
    HP controls 1 speed heat pump with 1 stage of aux heat.
    A2 controls two stages of cooling and one stage of furnace heat.
    H2 controls a 2 Speed HP with 1 stage of aux heat.
    AC controls 1 speed air conditioner with 1 stage of heat.
    H operates a heat only system: furnace or fan coil only; no outdoor unit.
    C operates a cool only system: outdoor AC unit with an indoor fan coil; no strip heater support.
    Note that this option allows a HP thermostat to be converted to control an AC system.
  2. Option 03 — Fahrenheit/Centigrade Selections:
    F = Fahrenheit — Default is Fahrenheit.
    C = Centigrade.
    Selects temperature measurement units.
  3. Option 04 — Fan (G) ON withWoutput Selections:
    OF = G not energized with W — This is default.
    ON = G energized with W.
    This selection determines whether the fan (G) is to be ON or OFF when the W (furnace or strip heat) is ON. Furnaces and fan coils which manage their own blowers do not require a separate G signal. Some auxiliary heaters require a separate G signal to operate the blower when W is applied.
  4. Option 07 — Zoning Selections:
    OF = non–zoned system — This is default.
    ON = zoned system.
    ON disables thermostat’s internal timers which are not needed with zoning system controls. Must be set to OF for non–zoned systems.
  5. Option 10 — Reversing valve
    This selection is only available on heat pump systems. “O” terminal can be configured to be energized in either heating mode or in cooling mode, depending on heat pump operation. “O” is used to describe a heat pump system that energizes its reversing valve in cooling. “B” is used to describe a heat pump system that energizes its reversing valve in heating.
    H — Reversing valve output (O/W2/B) is energized when HEAT mode is selected.
    C — Reversing valve output (O/W2/B) is energized when COOL mode is selected.
    Default is C.
  6. Option 11 — Minimum Deadband Between Heating And Cooling Selections: 01 through 06 — Default is 02.
    Sets the minimum allowable number of degrees between heating and cooling
    setpoints. One setpoint will “push” the other to maintain this difference.
  7. Option 12 — Smart Recovery (programmable model only) Selections: OF, 30, 60, 90 — Default is 90.
    Smart Recovery OF means setpoints change immediately at a program schedule change. Thirty, 60, or 90 selects the number of minutes recovery starts before programmed recovery time. Recovery takes place smoothly during the selected recovery time, ending at the recovery time and temperature which is programmed.
    If the setpoint is changed during smart recovery, the smart recovery is cancelled and the new setpoint is effective immediately. Not available with non–programmable thermostats.
  8. Option 13 — Room Air Temperature Offset Selections: –5 to 5_ F — Default is 0.
    This option selects the number of degrees F to be added to the displayed temperature to calibrate or deliberately miscalibrate the measured room temperature.
  9. Option 15 — Auto Changeover Availability Selections:
    ON — This is default.
    OF
    ON allows automatic changeover between heating and cooling as demand requires.
    OF maintains either heating or cooling mode only. Auto changeover is not available when H or C is selected under Option 1.
  10. Option 16 — Maximum Cycles Per Hour Selections: 2, 4, or 6 — Default is 4.
    The maximum cycle rate is limited by internal timers to the selected number of cycles per hour. Selection of a higher number causes faster cycling resulting in more constant room temperature.
  11. Option 17 — Minimum Time Between Equipment Stages Selections: 10, 15, 20, 25 — Default is 15.
    When there is an auxiliary stage of heat available, this is the amount of time the heat pump must operate before the aux stage can turn on. With heat pumps, longer times can reduce the amount of auxiliary heat used. Not available with AC thermostats.
  12. Option 18 — Backlight Configuration Selections: ON, OF — Default is OF.
    When ON is selected and the thermostat is not battery operated a low level continuous display backlight is always on. With OF selected, the backlight is only on for a short time after the door is opened or a key is pressed. Continuous backlight is not available with battery operation.
  13. Option 21 — Keypad Lockout Selections: ON, OF — Default is OF.
    With OF selected, the keypad cannot be locked. With ON selected the keypad will be locked and can be unlocked by simultaneously pressing the UP and DOWN keys for 5 seconds. Once unlocked, it will relock 2 minutes after the last keypad press. A “lock” icon is displayed while it is locked.
  14. Option 24 — Programmable/Non–Programmable (programmable model only) Selections: P, nP — Default is P.
    This option is only available on programmable models, allowing programming to be disabled when nP is selected. The clock is displayed, but the program schedule, the HOLD and TEMPORARY HOLD functions are disabled.
  15. Option 25 — Number of Programmable Periods (programmable model only) Selections: 2, 4 — Default is 4.
    Selecting 2 allows 2 programming periods, P1 and P2, per day. Selecting 4 allows periods P1, P2 , P3, and P4. Not available with non–programmable thermostats.
  16. Option 26 — Minimum Cooling Setpoint Selections: 52_ to 90_ — Default is 52_F.
    Sets the lowest cooling setpoint available to the user.
  17. Option 27 — Maximum Heating Setpoint Selections: 50_F to 88_F — Default is 88_F.
    Sets the highest heating setpoint available to the user.
  18. Option 99 — Reset to Factory Defaults Selection:
    See below — There is no default.
    Use this capability to reset the thermostat to “out of the box” conditions.
    NOTE: All configuration settings, program settings, clock, and day which have been manually entered will be lost!
    When this option is selected, the configuration number (99), will appear on the left and 10 will appear on the right. To perform the reset, first use the MODE key to make the 10 flash. Then press and hold the DOWN key. The 10 will start counting down toward zero. If the DOWN key is kept pressed until the count reaches zero, the reset will be performed. If the DOWN key is released early, the number will return to 10 and the reset will not occur

Step 4 — Check Thermostat Operation

The Comfort Series thermostats have a built–in installer test capability. Use it to check thermostat and equipment operation without delays or setpoint adjustments to force heating or cooling. To enter the Installer Test mode, use the same process as is used to enter Installer Configuration, only hold the FAN key longer. More specifically, press and hold the FAN for about 15 seconds until the display reads In on the left and St on the right for the programmable model, or InS in the smaller display for the non–programmable model. The MODE will be OFF. The MODE key (upper left) can now be used to select heat, cool, or emergency heat, if this is a HP thermostat. Selecting one of the available modes will immediately command the equipment to turn on in that mode. It will run for 3 minutes and then return the mode to off.With HP thermostats (having 2 stages of heating), the test will run for 3 minutes on each stage. If the thermostat is programmable, the clock display counts down from 180 seconds while each stage operates. Changing the mode to OFF will terminate any running test immediately. During any test, the display icons will be displayed the same as for normal operation of that stage, as follows:

SELECTED MODE DISPLAY ICONS
off off
cool cool on, 2 (for second stage cooling)
heat heat on, aux heat on
Em Heat aux heat on

To terminate the Installer Test mode press the DONE or FAN button. If the thermostat is left in Installer Test mode, it will revert back to normal operation after 15 minutes.

Checklist

  1. Run equipment through several heating and cooling cycles to ensure proper operation. To operate the thermostat in its normal operating mode, consult the Owner’s Manual.
  2. If the equipment is to be left in operation, the setpoints, operating mode, and possibly program schedule must be properly selected.
  3. Put away tools and instruments and clean up debris.
  4. Review and leave Owner’s Guide with owner.
