INTRODUCTION
Carrier’s 7-day programmable/non-programmable Thermidistat Control is a wall-mounted, low-voltage control which combines temperature and humidity control in a single attractive unit. An extension of Carrier’s proven line of thermostats, it provides separate set points for heating and cooling, and now adds humidi­fication and dehumidification. Different heating and cooling set points and times are programmable for 4 periods per day and 7 days per week. The Thermidistat Control can also be field­configured as a non-programmable thermostat. When operating in the non-programmable configuration it will still have both tem­perature and humidity control. Humidify and dehumidify outputs provide direct control of humidity. Batteries are not used. During power loss an internal memory stores programs and settings for unlimited time, and the clock continues to run for at least 8 hr.

INSTALLATION CONSIDERATIONS
POWER Note that this control does not require batteries and is not "power
stealing." It does require 24vac (R and C terminals) of the low-voltage transformer to be connected to it for proper operation. It will not operate without these 2 connections.
MODELS There is a single programmable/non-programmable model for all
applications. It can be configured for AC or HP, 1- or 2-speed compressor, and for dual fuel installations, allowing it to be used in place of all Carrier thermostats.
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.
DO NOT connect Furnace HUM terminal directly to
Thermidistat HUM terminal. This will bypass furnace safety controls. See Low Voltage Wiring Daigrams and notes for proper connection.
DEHUMIDIFY EQUIPMENT AND CONNECTIONS The dehumidify output connects to the dehumidify input on

INSTALLATION
Step 1—Thermidistat Control Location
Thermidistat Control should be mounted:
• Approximately 5 ft (1.5m) from floor.
• Close to or in a frequently used room, preferably on an inside partitioning wall.
• On a section of wall without pipes or duct work.
Thermidistat Control should NOT be mounted:
• Exposed to direct light or heat from a lamp, sun, fireplace, or other temperature-radiating objects which could cause a false reading.
• In areas with poor air circulation, such as behind a door or in an alcove.
Step 2—Set DIP Switches
There is a 4 section DIP switch within the Thermidistat Control which must be properly set by the installer. It is easiest to set these 4 switches before the Thermidistat Control is mounted to the wall, so STOP and complete the following steps:
1. Open hinged Thermidistat Control cover.
2. Remove cover completely by snapping it apart at hinge.
3. Open Thermidistat Control by pressing back half of the right end of plastic case inward while, at the same time, pulling front and back halves apart at the right end. The 2 halves will swing apart.
4. Snap hinge apart to completely separate the 2 halves.
5. Switches are located in upper right corner of circuit board. To change switch position, use corner of a small screwdriver to slide switch to opposite position.
6. After switches have been set, do not reassemble the 2 halves. The rear plastic will first be mounted to the wall.
SWITCH 1—AC/HP SELECT Use this switch to select between air conditioner and heat pump
systems. TO SET:
OFF—for air conditioner installations. This is factory default. ON—for heat pump installations, using either a fan coil or furnace (dual fuel).
SWITCH 2—1 SPEED/2 SPEED This switch tells the system whether the compressor is 1 or 2
speed. TO SET:
OFF—for single-speed compressor. This is factory default. ON—for 2-speed compressors, whether AC or HP.
SWITCH 3—SMART/CONVENTIONAL RECOVERY Selects between conventional and smart recovery from setback.
TO SET: OFF—for smart recovery. This is factory default. ON—for conventional recovery.
SWITCH 4—INSTALLER TEST OFF/ON Selects a special installer test mode which assists with system
TO SET: OFF—for normal operation. This is factory default. ON—for installer test mode.
Step 3—Install Thermidistat Control
Before installing Thermidistat Control, turn off all power to equipment. There may be more than 1 power disconnect. Electrical shock can cause personal injury or death.
1. Turn off all power to equipment.
2. If an existing thermostat is being replaced: a. Remove existing thermostat from wall. b. Disconnect wires from existing thermostat, 1 at a time. c. As each wire is disconnected, record wire color and
terminal marking.
d. New or additional wire may be needed to accommodate
added humidity outputs.
e. Discard or recycle old thermostat.
NOTE: Mercury is a hazardous waste and MUST be disposed of properly.
3. Select Thermidistat Control rear plastic. (If it is not separated from the remainder of the Thermidistat Control, refer to Step 2 above.)
4. Route wires through large hole in rear plastic. Level rear plastic against wall (for aesthetic value only—Thermidistat Control need not be leveled for proper operation) and mark wall through 2 mounting holes.
5. Drill two 3/16-in. mounting holes in wall where marked.
6. Secure rear plastic to wall with 2 screws and anchors provided. Additional mounting holes are available for more secure mounting if needed. Make sure all wires extend through hole in mounting base.
7. Adjust length and routing of each wire to reach proper connector block and terminal on rear plastic with 1/4-in. extra length. Strip only 1/4 in. of insulation from each wire to prevent adjacent wires from shorting together when con­nected.
8. Match and connect equipment wires to proper terminals of each connector block. (See Low Voltage Wiring Diagram Reference Chart and Figs. 1 through 28 in separate Wiring Diagram literature). Remember R and C must be connected for proper operation.
Improper wiring or installation may damage Thermidistat Control. Check to make sure wiring is correct before proceed­ing with installation or turning on power.
9. Push any excess wire into wall and against rear plastic. Seal hole in wall to prevent air leaks. Leaks can affect operation.
10. Reattach Thermidistat Control body to rear plastic by first reattaching hinge.
12. Turn on power to equipment.
On power up, all display segments will light for 5 sec. For the next 5 sec, a 2-digit code appears on large display which identifies Thermidistat Control configuration:
1. AC—for 1-speed air conditioner
2. HP—for 1-speed heat pump
2
3. A2—for 2-speed air conditioner
4. H2—for 2-speed heat pump
5. dF—for 1-speed dual fuel
6. d2—for 2-speed dual fuel
7. HS—for 1-speed heat pump with Intelligent Heat Staging (3-stage auxiliary heat with 40FK, FK4C, or FV4A Series fan coils.)
Step 4—Set Thermidistat Control Configuration
Configuration options, like DIP switch settings, are intended to be selected at installation and normally are not modified by the homeowner. These options are not discussed in the homeowner’s manual and therefore must be made as part of the installation. A special procedure allows entry into the configuration mode. While in configuration mode, up to 17 selections can be made. A description of each selection and how to use the configuration mode follows.
CONFIGURATION OPTIONS — SUMMARY: Option 1—Anticipator adjustment Option 2—Clean filter timer adjustment Option 3—English/Metric selection Option 4—Fan (G) ON with W selection Option 5—Variable-speed blower present selection Option 6—Cooling lockout below 55° selection Option 7—Variable-speed super dehumidification selection (only
available when variable-speed blower is used) Option 8—Auxiliary heat lockout temperature setting (only avail-
able when heat pump is used) Option 9—Intelligent Heat Staging selection (only available when
single-speed heat pump is used) Option 10—Dual Fuel selection (only available when heat pump is
used) Option 11—Balance point setting (only available when Dual Fuel
is selected) Option 12—Defrost heat selection (only available when heat pump
is used) Option 13—Room temperature offset adjustment Option 14—Heat/cool dead band adjustment Option 15—Enable Auto mode Option 16—Enables Super Comfort Heat Mode Option 17—Non-Programmable selection TO ENTER CONFIGURATION MODE: Press and hold FAN button for approximately 10 sec until COOL
set point display indicates a flashing 1. The Thermidistat Control is now in configuration mode. It will automatically exit this mode if no button is pressed for 3 minutes. Pressing END button will exit configuration mode immediately.
WHILE IN CONFIGURATION MODE: The upper small (COOL set point) display indicates selected
press SET TIME/TEMP button once. The large display will now flash, indicating that up and down buttons now control available choices within that option. Each press of TIME/TEMP button switches between available option (small display) and available selections within each option (large display).
CONFIGURATION OPTIONS — SELECTION:
Option 1—Anticipator Adjustment
This adjustment controls sensitivity and cycle rate of Thermidistat Control. Higher numbers decrease sensitivity and slow cycle rate. Lower numbers increase sensitivity and cycle rate. However, a limiting feature will not allow more than 4 cycles per hr, regardless of setting. Anticipator values can range from 1 to 9. Factory default is 3. This default selection provides optimum performance in nearly all installations. Try it first. Do not change setting unless there is evidence of need to do so.
Unlike conventional anticipators, this setting is not determined by current draw. There is no need to measure, know, or compensate for current draw. There is also no droop with this Thermidistat Control. Regardless of setting and number of stages, both heating and cooling will control to their respective set points.
