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. 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

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.

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.

Option 11 — Deadband Setting Between Heat & Cool

This option is not available on Heat Only and Cool Only systems. The selection allows the installer to choose how much differential exists between the heating and cooling setpoints. Allowable selections are 1--6.

Default is 2.

Option 12 — Smart Recovery

Smart Recovery OF (off) means setpoints change precisely at setback recovery time. 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. Not available with non--programmable Thermidistat Controls or when Thermidistat Control is configured as non--programmable.

Default is 90.

Option 13 — Room Air Temperature Offset Adjust

The number of degrees to be added to the displayed temperature to calibrate or deliberately miscalibrate the measured room temperature ( -- 5 to +5_).

Default is 0.

Option 14 — Humidity Display Offset Adjust

The percentage to be added to the displayed humidity to calibrate or deliberately miscalibrate the measured room humidity (--9% to +9% RH).

Default is 0.

Option 15 — Enable Auto Mode

This selection is not available if the Thermidistat Control is configured as Heat Only or Cool Only in Option 1. This allows the homeowner to select auto changeover mode in addition to heat and cool. This allows the Thermidistat Control to automatically change between heating mode and cooling mode when sufficient demand for heating or cooling exists.

On — Auto mode is available. OF — Auto mode is not available.

Default is On.

Option 16 — Maximum Cycles Per Hour

This selection limits the number of cycles per hour that the Thermidistat Control allows the system to operate. Selections are 2, 4, 6.

2 — The heating and cooling outputs will be energized no more than 2 times per hour. When an output is energized, it will not be energized again for 30 minutes.

4 — The heating and cooling outputs will be energized no more than 4 times per hour. When an output is energized, it will not be energized again for 15 minutes.

6 — The heating and cooling outputs will be energized no more than 6 times per hour. When an output is energized, it will not be energized again for 10 minutes.

Default is 4.

Option 17 — Time Between Equipment Stages

This selection is only available for heat pump systems. This determines the minimum number of minutes of equipment operation on the highest compressor stage before allowing the transition to auxiliary heat. Available selections are 10, 15, 20, and 25. The time between stages of any individual piece of equipment, such as low speed and high speed compressor or fan coil stages, will be fixed at 10 minutes.

Default is 15.

Option 18 — Backlight Configuration

When OF (off), the backlight will be lit for 10 seconds after a button is pressed. After 10 seconds of no button presses, the backlight turns off. When On, the backlight will normally be on and dim in appearance. The backlight brightness becomes brighter when a button is pressed. After 10 seconds of no button presses, the backlight will return to the dimmer level until another button press occurs. The range of brightness is 1 through 5 with 5 being full brightness.

Default is 3.

Option 19 — Dry Contact Configuration (programmable models only)

There are 3 available selections, OF, 1 and 2. OF — The dry contact is always de-- energized.

1 — The dry contact will be energized for the specified number of minutes per hour. This selection is programmable by period. When this selection is changed from OF to 1, the period icons are shown and the minute segments of the clock display are shown.

See Operational Information and Wiring Diagrams for further explanation of dry contact configuration and use. To change the period or minutes, press the soft key below

the period or minutes and then use the UP/DOWN buttons to change to the desired value.

2 — The dry contact will operate as a DH relay. This relay is reverse logic. When the humidity level is above the dehumidify setpoint, the dry contact D1--D2 will be opened. When the humidity level is below the dehumidify setpoint, D1--D2 will be closed. There is a +/-- 2% hysteresis around the dehumidify setpoint to prevent rapid on/off cycling of the DH output. When configured for dehumidification, the Rc terminal must be connected to one of the dry contact terminals. This provides power to energize the dehumidify terminal on the cooling equipment when the dry contact is closed. See Wiring Diagrams for more information.

Default is OF (off).

Option 19 — Dry Contact Configuration (non--programmable models only)

OF — The dry contact is always de-- energized. ON — The dry contact will operate as a DH relay. This relay is reverse logic.

When the humidity level is above the dehumidify setpoint, the dry contact D1--D2 will be opened. When the humidity level is below the dehumidify setpoint, D1--D2 will be closed. There is a +/-- 2% hysteresis around the dehumidify setpoint to prevent rapid on/off cycling of the DH output. When configured for dehumidification, the Rc terminal must be connected to one of the dry contact terminals. This provides power to energize the dehumidify terminal on the cooling equipment when the dry contact is closed. See Wiring Diagrams for more information.

Default is OF (off).

Option 20 — Outdoor Air Temperature Offset Adjustment

An outdoor sensor is required for high cool latch feature.

This selection is only available when Option 1 is set to H2, A2, or h2 and when Option 7 (zoning) is set to OF (off). Configuration settings are OF (off), 80, 85, 90, 95, 100, 105, 110, On.

OF (off) — Cooling always starts in low stage (Y1) and stages up to high stage (Y1 and Y/Y2) when demand is sufficient and staging timer constraints have been satisfied.

80--110_F/27--43_C — Outdoor temperature above which both first and second stages of the compressor are energized to satisfy all cooling demands. When a cycle starts under a high cool latch, it will finish the cooling cycle on high stage. If the cooling equipment is energized to satisfy a dehumidify demand only (no cooling demand), the latch will not be applied.

On — The Y1 and Y/Y2 outputs are simultaneously energized to satisfy all cooling demands.

Default is OF (off).

Option 23 — High Heat Latch Temperature (only available if outdoor sensor is present)

This selection is only available when Option 1 is set to H2, or h2 and Option 7 (zoning) is set to OF (off). Configuration settings are OF (off), 20, 25, 30, 35, 40, 45, 50, On.

OF (off) —Heating always starts in low stage (Y1) and stages up to high stage (Y1 and Y/Y2) when demand is sufficient and staging timer constraints have been satisfied.

20--50_F/--7--10_C — Outdoor temperature below which both first and second stages of the compressor are energized to satisfy all heating demands. When a cycle starts under a high heat latch, it will finish the heating cycle on high stage.

On — The Y1 and Y/Y2 outputs are simultaneously energized to satisfy all heating demands.

Default is OF (off).

Option 24 — Programmable/Non--Programmable (programmable models only)

This selection allows the installer to configure the Thermidistat Control as either programmable or non--programmable. Selections are P, nP.

Default is P.

Option 25 — Number of Programmable Periods (programmable models only)

This selection allows the installer to configure the Thermidistat Control for two or four periods per day. Two periods is a common commercial application and

four periods is more common for residential. This selection is not available if Option 24 has been set to nP to configure the Thermidistat Control for non--programmable operation.

2 — Periods DAY and SLEEP are available 4 — Periods WAKE, DAY, EVE, and SLEEP are available. Default is 4.

Option 26 — Minimum Cooling Setpoint

This selection allows the installer to configure the minimum cooling setpoint that the user is allowed to set. The range is based on the value of the adjustable deadband Option 11, such that the minimum of the range is 50_F/10_Cplusthe adjustable deadband and the maximum is 90_F/32_C.

Default is 52_F/11_C (based on the adjustable deadband default = 2).

Option 27 — Maximum Heating Setpoint

This selection allows the installer to configure the maximum heating setpoint. The range is based on the adjustable deadband value Option 11, such that the minimum of the range is 50_F/10_C and the maximum is 90_F/32_C minus the deadband.

Default is 88_F/31_C (based on the adjustable deadband default = 2).

Option 28 — UV Light Reminder

This selection allows the installer to select the number of months after which the UV Light icon will be displayed to indicate to the homeowner that it is time to call the dealer to have the UV Lights replaced. Selections available are OF (off), 6, 12, 18, 24, 30, 36, 42, 48.

OF (off) — The UV Light reminder is turned off and will never be displayed.

6--48 — The number of months after which the UV Light reminder will be displayed, “CHECK UV LIGHT”.

Default is OF (off).

Option 29 — Humidifier Pad Reminder

This selects the number of months after which the Humidifier Pad Reminder icon will be displayed. This is not based on run time.

OF (off) — The Humidifier Pad Reminder is disabled and will never be displayed.

1--24 — The number of months after which the Humidifier Pad Reminder icon will be d isplayed, “CHECK HUM PAD”.

Default is OF (off).

Option 30 — Programmable Fan (programmable models only)

This selection allows the homeowner to program the fan selection to “Auto” or “On” fan operation for each of the program schedule periods. This selection is only available on programmable Thermidistat Controls.

OF (off) — Programmable fan is disabled and the homeowner must manually select “Auto” or “On” for fan operation.

On — Programmable fan is enabled. The homeowner can program “Auto” or “On” fan operation along with the heat and cool setpoints for each programmed period. When the program schedule is running, the programmed heat setpoint, cool setpoint, and fan selection for that period will be used. If the homeowner “overrides” the programmed fan setting by pressing the fan button, the override selection will remain in effect until the next programmed period time.

Default is OF (off).

Option 31 — Daylight Savings Time Configuration (programmable models only)

This selection allows the installer to set the Thermidistat Control to automatically change by one hour on the specified day, month, and week specified.

OF (off) — Daylight Savings Time Function disabled.

1,2 On — The first time the UP/DOWN button is pressed, the value of this selection changes from OF (off) to 1. When 1 is displayed, the days of the week and clock digits will be turned on. The installer will set the start date (Spring) for Daylight Savings Time by setting the day of the week by selecting the appropriate triangle icon next to the days of the week, the month of the year will be set in the clock hours location (range 1--12) and the week of the month will be set in the clock minutes location. The week of the month selections will be F, 2, 3, 4, and L for First, 2nd, 3rd, 4th, and Last. So for the first Sunday in April, the display would show SUN, 4, F. When 2 is displayed, the installer will then choose the end date for daylight savings time (Fall). To activate the function, the installer changes the “2” by pressing the up button and “On” is displayed. The setting shall be left “On” to enable the Daylight Savings Time function.

Default is On (on).

Option 32 — Furnace Heat Staging Control (available only when the Thermidistat Control is configured to operate AC or A2 equipment).

1 — Thermidistat Control controls W1 output only and furnace controls the turn on and turn off of higher stages of heat.

2 — Thermidistat Control will control the W1 and O/W2/B outputs.

Default is 1.

Option 33 — Single or Two--Piece Installation

This configuration allows the Thermidistat Control to compensate for the amount of heat generated by the Thermidistat Control electronics to allow more accurate sensing of the temperature sensor. The amount of heat compensation will be different between single installation and two--piece installation.

Range: 1P or 2P 1P — The installation is single piece. 2P — The installation is two separate pieces.

Default is 2P.

Option 40 — Humidify Fan

This selection controls whether humidification can only be done when a heating demand is present. If the homeowner turns humidification OFF, this configuration operates as if the selection was set to OFF.

OF -- The humidity output will only energize when there is a humidity demand and the heating equipment is energized.

On -- The humidity output and the fan will energize anytime humidification is needed during heating mode regardless of the state of the heating equipment.

Factory default is OF (Off)

Option 41 — Variable Speed Blower

This selection allows the installer to select between a single speed or variable motor. In a system with a two speed compressor (A2, h2, H2), if a dehumidification demand exists and the compressor is energized for cool to dehumidify, cooling, or both, and the system has a PSC blower (Option 41 = OFF), then both Y/Y2 and Y1/W2 are energized.

Off -- The system has a single speed (PSC) blower.

On -- The system has a variable speed blower.

Factory default is OF (Off)

Option 42 — Variable Speed Super Dehumidification

This option will only be available if the Variable Speed Blower setup (Option

41) has been set to ON.

OF -- The fan output (G) is energized when the compressor is on for cool to dehumidify functionality.

On -- The fan output (G) is de--energized when the compressor is running for cool to dehumidify functionality. In this setup the fan will run at very low speed because a Y/Y2 or Y1/W2 is present but the G signal is not. The fan output (G) will be energized any time the compressor is energized in response to a cooling demand.

Factory default is OF (Off)

Option 43 — Intelligent Heat Staging

This function is only available if the equipment configuration is a single speed heat pump (Option 01 = HP) and the thermostat is a Tx --PRH or Tx--NRH model. The Y1/W2 output, which energizes the second stages of heat, is only populated on these models.

Off -- Electric heat will not be staged.

On --Three stages of electric heat will be staged. This switch should be set to On if the HVAC equipment has two banks of strip

heaters. When electric heat is required, the thermostat will energize the smallest bank first (W1 only), then the larger bank (turning the smaller bank off -- Y1/W2 only), and then both banks together (both W1 and Y1/W2). When power is cycled to the thermostat, this unit configuration will be displayed as HS.

Factory defaults is OF (Off)

Option 44 — Super Comfort Heat

This option is only available on heat pump units HP (HP, H2, hh, and h2) when Option 41 (Variable Speed Blower) is set to On and the system has a valid OAT sensor.

OF (Off) -- Comfort Heat is off

On -- Comfort Heat feature is on. If the outdoor air temperature is between 12 -- 40_F / -- 1 1 -- 4 _Candthe

compressor is running in heating, then the fan output is turned off. This will signal the variable speed blower to reduce the air speed. The fan output is turned off even if the user has the fan selection set to continuous fan. The fan output will be turned back on in this temperature range if the maximum capacity of auxiliary heat is on due to system demand (auxiliary heat on in response to a defrost signal shouldn’t cause the fan to turn back on).

If the outdoor air temperature is below 12_F/--11_C and there is sufficient demand for the equipment to be on, then the fan output is turned back on and the W/W1 output is energized. In a two speed unit the Y/Y2 output should be energized in addition to the W/W1 output. This logic does not apply to a hybrid heat system. In the unlikely event that the installer has selected a heat pump lockout temperature (Option 09) of 5_F/--15_C in a hybrid heat system and the comfort heat feature is on, then the comfort heat feature will turn the W/W1 on and the compressors off when the outdoor air temperature drops below 12_F/-- 11_C instead of at the lower temperature of 5_F/--15_C.

NOTE: All temperature boundaries have a +/-- 2_ hysteresis

Factory default is OF (Off).

Option 99 — Reset to Factory Defaults

Use this capability to reset the Thermidistat Control to “out of the box” conditions. BEWARE! All configuration settings, program settings, clock, and calendar 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 move the box from the 99 to the 10 (programmable model) or to flash the 10 (non-- programmable model). 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. When the value reaches zero, the heat setpoint shall display ----. The cool setpoint shall display -- and the room air temperature shall display Fd. When the factory defaults have been restored, the Thermidistat Control will act as if power was cycled and return to normal operation. If the DOWN key is released early, the number will return to 10 and the reset will not occur.

SYSTEM START--UP AND CHECKOUT

The Thermidistat Control is designed with a built--in installer test capability. It allows easy operation of equipment without delays or setpoint adjustments to force heating or cooling. To enable installer test mode, press and hold the fan button for 15 seconds. After 10 seconds, the Thermidistat Control will enter Configuration Mode. Continuing to hold the Fan button through 15 seconds will cause the Thermidistat Control to enter Installer Test Mode. Pressing the Mode button will change the system operating mode to test the heating and cooling equipment. Auto Mode is not available during Installer Test Mode. If no buttons are pressed for 15 minutes, the installer test mode will be terminated. Pressing DONE at any time will exit installer test mode.

Heat -- The first stage of heating will be energized for three minutes, then the first and second stages (if a second stage exists) will turn on for an additional three minutes. During the first stage of heating, the HEAT ON icons will be displayed. During the second stage of heating (if one exists), the “2” next to the “On” will be displayed if the system has a two--stage compressor (A2, h2, or H2 unit types). The “auxiliary heat on” icon will be displayed if the second stage is electric heat (HP unit type). For Hybrid Heat installation or heat pump installation, only 1 stage of auxiliary heat is available. Any staging of auxiliary heat must be managed by the furnace or fan coil. While the heating test is active, the humidify output can be toggled. On the programmable models, pressing the button below the humidify icon shall toggle the state of the humidify output. On the non --programmable models, pressing the features button shall toggle the state of the humidify output.

Installer test for cooling is the same as described for heating above. COOL ON will be displayed during cooling in Installer Test Mode. While the cooling test is active, the dehumidify icon shall be displayed if the dry contact has been configured as a DH output. On the programmable models, pressing the button below the dehumidify icon shall toggle the state of the dry contact output. On the non--programmable models, pressing the features button shall toggle the state of the dry contact.

In a heat pump application, when the mode is set to “em heat” the auxiliary heat will turn on for 3 minutes. The clock display will count down from 180 to 0 during this test.

TO TEST FAN Fan button switches FAN icon between AUTO and On. While On is displayed,

G output will be energized, turning fan on. Allow up to 10 sec after button is

pressed for fan to turn On and off. On some fan coils, fan continues to operate for 90 sec after G signal is removed.

Final Settings

Be sure to press DONE to exit installer setup mode. If the system is to b e left in operation after installation is complete, use MODE button to select between HEAT, COOL, or AUTO to provide desired operation of heating, cooling, or auto.

On the programmable models, the default setpoints and programmed schedule conform to the Energy Starr requirements of the U.S. Department of Energy for both heating and cooling. These provide energy saving temperature settings. Refer to Table 1.

Table 1 – Energy Star Default Schedule

SCHEDULE HEAT COOL

Wake 6:00 AM Day 8:00 AM Evening 5:00 PM Sleep 10:00 PM

If the programmed schedule is to be used, make sure the triangle icon next to the FOLLOW SCHEDULE icon is turned on. Pressing the Schedule button will cycle the triangle icon through the FOLLOW SCHEDULE, HOLD and VACATION selections.

If fixed temperatures are desired, use SCHEDULE button to turn on arrow icon next to HOLD. This will maintain setpoints, not allowing them to change with programmed schedule.

The FAN button may be used to select between AUTO (fan on only with equipment) and On (fan on continuously) fan modes. For further information on temperature selection and programming, refer to Homeowner’s Guide.

Setting The Clock, Calendar, Daily Schedule, and V acation Settings (programmable models only)

To set the clock, press the SET button once. The Clock will be displayed at the bottom center of the screen. Use the soft keys to move the box around the digits to be set and the UP/DOWN buttons to change the setting. Concurrent presses of the set button will cycle through the calendar, daily schedule, and vacation settings.

Calendar may be changed by using the soft keys to select the Month, Day, or Year. The UP/DOWN buttons are used to change the Month, Day, or Year setting when the box surrounds it. Day of the week (Mon--Sun) is determined by calendar settings and is not directly adjustable.

When changing daily schedule settings, the soft keys are used to set the days, period times, heating setpoints, and cooling setpoints. The UP/DOWN buttons are used to change the setting with the box around it. ALL PROGRAM PERIODS (WAKE, DAY, EVE, SLEEP) MUST OCCUR WITHIN T HE SAME 24 HOUR PERIOD.

When changing Vacation settings, the soft keys are used to choose the selection to be adjusted and the UP/DOWN buttons are used to change the setting. Humidify setting may only be changed when heat mode is selected and Dehumidify setting may only be changed when cool mode is selected.

Humidity Control Features

The various humidity control features of the Thermidistat Control are explained below. They are grouped into 2 sections, humidification and dehumidification. Instructions on how to select each feature are given at the end of each section.

Humidification

The Thermidistat Control directly connects to a standard 24VAC humidifier to control humidification in the home. A humidify setpoint between 10 and 46% in 2% increments relative humidity is selected by the homeowner, or all humidification can be turned off. When humidity in home drops below setpoint, humidifier will be turned on to raise humidity level. Humidification can only occur while heating. See Table 2 for reference.

Table 2 – Humidification Selections

SELECTION FAN DISPLAY

Normal Humidify Blank 10--- 46

Auto Humidify AUT O 1 --- 9

Humidify Off Blank OF (Off)

1. Humidify In normal humidify, humidifier will be on if there is humidity demand and any heating equipment is on. This will include furnace, heat pump, or auxiliary heat.

2. Auto Humidify Thermidistat Control will automatically adjust the humidity setpoint according to the outdoor temperature. As the outdoor temperature decreases, the humidity setpoint also decreases. Settings ranging from 1 to 9, 1 being the lowest and 9 the highest, will be visible to the homeowner.

HUMIDIFY SETPOINT

DISPLAY

See Fig. 16 for outdoor temperature/indoor humidity relationship in auto humidify mode.

3. Humidify Off The humidify function can be turned off completely. This does not require changing existing setpoints.

To Select Humidification (programmable)

Press the soft key below the humidify icon to bring up humidity select screen. Humidify options are only available when in Heating mode. When system is in AUTO mode, humidify options are available if the last system operation was a call for heat.

To Select Humidification (non--programmable)

Press the features button twice. The first press displays the outdoor air temperature and the second press displays the humidity value and humidify target.

Pressing the mode button shall cycle through the available humidification selections (Off, Humidify and Auto Humidify).

Additional Humidify Comments

The humidifier is actually turned on when humidity is 1% below setpoint and turned off when it reaches 1% above setpoint. This built-- in hysteresis prevents humidify output from toggling on and off when humidity level is near setpoint.

Dehumidification

Dehumidification is done only during cooling. Depending on type of equipment used, compressor speed, blower speed, setpoint adjustment, and equipment cycling are modified to provide added dehumidification. A dehumidification setpoint (separate from humidification setpoint) is available to the homeowner. It can range from 46% to 66% relative humidity. When actual humidity is higher

than setpoint, a dehumidification demand exists. The Thermidistat Control responds by activating the dry contact (when enabled in Option 19). It may also control the compressor and blower, depending on equipment type and dehumidify selection choice. The 3 available selections are described below. A mandatory 5 minute blower off delay will be enforced if there has been a call for dehumidification during a cooling call. The amount of extra dehumidification available is very dependent on the type of equipment in the home. Without a variable--speed blower, the system’s ability to adjust dehumidification is very limited.

1. Normal Dehumidify Operation When normal dehumidify is selected, the compressor will not turn on without a cooling demand. If dehumidify demand exists while cooling, dry contact will also be active (24VAC removed). This output commands variable--speed blowers to reduce their airflow, which improves water removal from the cooled air.

2. Cool to Dehumidify The cool to dehumidify selection tells the system to operate the compressor, within limits, when there is a dehumidify demand even if there is no cooling demand. The limits are that the system may overcool up to 3_, but no more, while attempting to satisfy a dehumidify demand. Within this 3_ range, there is an additional balance between overcooling and humidity satisfaction. When overcooling must occur, the dehumidify setpoint is adjusted upward by 2% per degree of overcooling. For example, a cooling setpoint of 76_F/24_C and a dehumidify setpoint of 60% is equivalent to a cooling setpoint of 75_F/24_C and a dehumidify setpoint of 62%. This dehumidify setpoint change is internal to the Thermidistat Control and is not shown on the display.

Fig. 16 -- Auto Humidity

3. Dehumidify Off Dehumidification can be turned off completely. This can be done without changing existing setpoints.

To Select Dehumidification (programmable -- between NORMAL, COOL TO, and OFF)

Press the soft key below the dehumidify icon button to bring up dehumidify selections. Dehumidify options are only available when in Cooling mode. When

system is in AUTO mode, dehumidify options are available if the last system operation was a call for cooling.

To Select Dehumidification (non--programmable -- between NORMAL, COOL TO, and OFF)

Press the features button three times. The first press displays the outdoor air temperature, the second press displays the humidify options and the third press will display the current dehumidify selections.

The mode button is used to cycle through the dehumidify selections.

Additional Dehumidify Comments

Dehumidification can be enhanced (with some efficiency loss) by turning blower off immediately at the end of each cooling cycle (eliminating normal 90 sec blower off delay). Where maximum humidity removal is desired, this should be done. Fan coils have the capability of removing this off delay. On FK or FV Fan Coils, set delay tap to 0/0. On standard fan coils, a jumper can be cut to disable off delay. Refer to fan coil Installation Instructions for details. If FAN is set for continuous operation (fan On icon displayed), G output is turned off for 5 minutes at the end of each cooling cycle as long as dehumidify demand exists.

Like humidify, dehumidify actions are initiated when humidity is 1% above setpoint and are terminated when humidity drops to 1% below setpoint. This prevents unnecessary toggling of dehumidify actions when humidity is near setpoint.

Dehumidify Output and Equipment Connections

When there is a dehumidify demand, dry contact is activated, meaning that a 24VAC signal is removed from the DHUM or DH output terminal. In o ther words, dehumidify output logic is reversed -- output is turned On when no dehumidify demand exists and is turned OFF when demand exists.

Carrier FK and FV series variable--speed fan coils, all variable--speed furnaces, and select single and multi--stage furnaces with the dehumidify connection have dehumidify inputs which connect directly to Thermidistat Control dry contact. Refer to the furnace literature for dehumidification options.

The FK and FV series fan coils have a terminal marked DH which should be connected to the Thermidistat Control dry contact output. Jumper J1 on fan coil MUST be removed. It is located behind the DH terminal. Additionally blower delay tap on fan coil should be set to 0/0 (no On delay and no OFF delay) when using cool to dehumidify. With this selection, the blower stops when G signal is removed, preventing re--evaporation of water from the coil which would occur during the normal 90 sec blower off delay. See fan coil installation instructions for more information. (See Wiring Diagram Reference Chart and Fig. 2 through 20 in Wiring Diagram section at the back of this piece literature.)

The furnace dehumidify input acts differently depending on which style of variable speed, select single--stage or multi-- stage furnace control you have.

Vacation (programmable models only)

A vacation selection is available specifically for times where the home will not be occupied for an extended period. Vacation mode has an automatic hold, meaning that setpoints are not affected by the programmed schedule. Vacation mode is active for a specified period of time. While in vacation mode, the system provides temperature and humidity protection for the home in the selected mode, but not comfort. When vacation mode is active, an arrow will be displayed beside “VACATION” in the upper left corner of the display.

Vacation Setpoints

A special set of temperature and humidity setpoints exist which are active in vacation mode. They are adjustable by the homeowner, are exclusively for vacation mode, and are remembered from one vacation selection to the next. See Table 3 for default values.

Table 3 – Vacation Setpoints Default Values

MODE AUTO

Fan Auto Heat Setpoint 55 Cool Setpoint 85

Humidify Setpoint 20

Dehumidify Setpoint 60

Vacation Humidification

Normal humidify is available using vacation setpoints. Auto humidification is available, adjusting its setpoint with outdoor temperature the same as when occupied. Vacation humidification can be turned off independently of occupied humidification. While setting the Vacation setpoints, the Vacation humidify setpoint is accessible by pressing the soft key below the humidify icon when the box is around the heating setpoint.

Vacation Dehumidification

Normal Dehumidify, Cool to Dehumidify, and Dehumidify OFF are all available in vacation mode, and selection of one of these can be different from that of occupied. Vacation dehumidification selection and setpoints are remembered the next time vacation is used. While setting Vacation setpoints, the Vacation dehumidify setpoint is accessible by pressing the soft key below the dehumidify icon when the box is around the cooling setpoint.

OPERATIONAL INFORMATION

Timers

Five--Minute Compressor Timeguard

This timer prevents compressor from starting unless it has been off for at least 5 minutes. It can be overridden for 1 cycle by simultaneously pressing FAN and UP buttons.

Cycle Timer

Based on the selection of 2, 4, or 6 cycles per hour, this timer is set to 30, 15, or 10 minutes. This much time must elapse from the start of one cycle before another cycle can start. It serves to impose the cycles per hour limits. It can be defeated for one cycle by simultaneously pressing the FAN and UP buttons.

Ten-- Minute Staging Timer

In multistage heating or cooling, this timer prevents any higher stage from turning on until preceding stage has been on for 10 minutes. When staging between compressor and electric heat or between compressor and furnace heat, the time is configurable. The timer is configurable via Option 17. This timer is overridden if temperature error is greater than 5_ (usually due to a large change in desired temperature) and equipment stages up in 60 second intervals.

Defrost

When defrost occurs in a Hybrid Heat system, the furnace will operate during the defrost cycle. At the end of the defrost cycle, the furnace and heat pump will be de--energized while the fan is energized for 2 minutes allowing the heat exchanger to cool down. At the end of the 2 minute time, the heat pump will be re--energized if a call for heat still exists.

Detection of defrost will not work properly if the installer has configured the O/W2/B output to function as a B output. During heat pump heating, a defrost

signal shall be considered valid if the compressor output is energized and the defrost signal has been active for less than 15 consecutive minutes. Any defrost signal present for longer than 15 minutes shall be considered invalid.

Heat pump/fan coil and hybrid heat systems shall use this input to:

S Detect that defrost is in progress and energize the auxiliary heat to

provide homeowner comfort during the defrost cycle

S Allow a defrost cycle to run to completion regardless of the system

demand

Three--Minute Minimum on Time

In normal operation, when a stage turns on, it will not turn off for a minimum of 3 minutes. If the setpoint is changed, this timer is canceled, allowing the equipment to turn off immediately when the demand is removed.

Heat/Cool Setpoints (Desired Temperature)

A minimum difference of 1_ and maximum of 6_ is enforced between heating and cooling desired temperatures. This is done by allowing 1 setting to “push” the other, to maintain this difference. This difference is adjustable via Configuration Option 11.

Equipment On Indicators

When cooling equipment is on, a COOL ON icon is displayed. While cooling equipment operation is delayed by the time guard or cycle timer, COOL ON will flash. The same is true for HEAT ON icon.

During second stage compressor operation a “2” will be displayed with the HEAT ON or COOL ON icon. This is displayed when the Thermidistat Control is configured as H2, A2, or h2.

When the W is energized in a heat pump or Hybrid Heat system, the “auxiliary heat on” icon will be displayed.

Humidify and Dehumidify Indicators

When the Display Module door is closed, the humidify icon will be displayed when humidification is active and the dehumidify icon will be displayed when dehumidification is active.

Auto Changeover

When auto changeover mode is selected, a change from heat to cool (or vice versa) will not occur until an opposite mode demand has existed for 20 minutes. If setpoint is changed, 20 --minute requirement is deleted.

Emergency Heat Mode

When Thermidistat Control is configured as a heat pump and emergency heat is selected, all Y signals are locked out, and W becomes energized upon a call for heat.

Programmable Fan (programmable models only)

The fan output can be programmed based on period of the day. When programming for each day and period the fan can be set to On or AUTO.

Dry Con tact

On the programmable models, the dry contact that can be used for control of an auxiliary device. The dry contact may be configured to be closed for a specific number of minutes per hour for each period of the program schedule. This can be used to operate a ventilator, damper, system blower, or other auxiliary device. There are two terminals, D1 and D2.

On both the programmable and non--programmable models, when configured as a dehumidify output, it will operate cooling equipment capable of dehumidify function. When configured for dehumidification, the Rc terminal must be connected to one of the dry contact terminals. The other dry contact terminal is connected to the dehumidify terminal on the furnace or fan coil. This provides

power to energize the dehumidify terminal on the cooling equipment when the dry contact is closed.

If it is desired to operate a ventilator or other device, the D1 and D2 terminals can be connected directly to the equipment. This will provide a closed contact for the specified number of minutes per hour. See Option 19.

If timed control of the system blower is required, the dry contact can be used for this function. The G terminal can be connected to one of the dry contact terminals with the other terminal being connected to Rc and/or Rh for timed control of the fan. Note that this is not the same as programmable fan Option 30.

See Wiring Diagrams for more information.

TROUBLESHOOTING

If the display module doesn’t power up after power is applied, check the Rc/Rh and C terminals for 24VAC. If 24VAC is present, check the voltage between Vg and V+. This voltage will be approximately 12-- 20VDC. If voltage is present, check the polarity to make sure it is wired correctly. The display will not power up if polarity is reversed.

Error Codes

“-- -- ” -- If Thermidistat Control cannot properly read room temperature, display will indicate “-- --” and all outputs (except fan, if on) will turn off. In the case where the installer has selected to average the local sensor and the remote room sensor, the Thermidistat Control display will alternate between “-- --” for the failed sensor and the temperature sensed by the working sensor every 10

seconds. The control will operate from the temperature sensed by the working sensor.

E1 -- If the Display Module and the Equipment Control Module cannot communicate via two--wire connection, an E1 will be displayed.

E2 --ThereisnoE2errormessage. E3 -- If Thermidistat Control cannot properly read outdoor temperature, and it is

needed for proper operation, display will indicate “-- --” in the outdoor temperature location. If Option 06, 08, 09, 22, 23 or 44 is not set to OFF, display will indicate “----” in the outdoor temperature location.

E4 -- If Thermidistat Control’s internal memory fails, E4 will be displayed. Replace Thermidistat Control.

E5 -- If Thermidistat Control cannot properly read humidity, E5 will be displayed. Replace Thermidistat Control. If both Humidify and Dehumidify have been set to OF, the humidity value will be shown as “----” when viewed from the humidity menu, but no E5 will be shown in the display.

Table 4 can be used as a troubleshooting tool for determining which outputs will be active for a particular configuration and each operating mode.
