Introduction
TCONT402AN32DA is a digital non-programmable 3Heat/ 2 Cool/Heat Pump/ Heat-Cool wall mounted low voltage (24VAC) Comfort Control with backlit LCD and keypad. It maintains room temperature by controlling the operation of heating, cooling, heat pump and dual fuel systems. The Comfort Control is easily configured for heat pump or cooling only and gas or electric or dual fuel heat applications via the user friendly Installer Setup menu. The Comfort Control features include separate heating and cooling setpoints, selectable auto or manual changeover, adjustable energy saving mode, adjustable filter reminder, outdoor temperature sensing, remote room sensing and remote humidistat input. Setup selections and diagnostics are stored indefinitely in the Comfort Controls nonvolatile memory eliminating the need for battery backup.
Safety Considerations
Read the following manufacturer instructions carefully. Follow all local codes during installation. All wiring must conform to local and national electrical codes. Improper wiring or installation may damage the comfort 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 could result in minor personal injury or product and property damage.

Installation
Comfort Control - Location
The Comfort Control should be mounted approximately 60” (1.5m) off the floor on an interior partition wall. Never install the Comfort Control on an outside wall.

Figure 2
For proper temperature sensing, avoid mounting the Comfort Control where it will be exposed to heat radiated from lamps, sun light, fireplaces or any other radiant heat sources.
Avoid locations close to windows, behind doors or alcoves with poor air circulation, adjoining outside walls, or doors that lead to the outside.
Select a location that prevents the Comfort Control from being directly exposed to air currents from supply registers.
Mount the Comfort Control on a section of interior wall that does not contain hot and cold water pipes or ductwork.
Outdoor Sensor - BAYSEN01ATEMPA - Location
Careful consideration of the following recommendations will help the outdoor sensor provide continuous accurate readings:
1.Mount the outdoor sensor on the north facing side of the building in an area where it is exposed to freely circulating airflow and out of direct sunlight.
2.Do not allow hot air airflow from the attic or drafts from inside exterior walls to bias the sensors operation. Always seal the hole where control wiring passes to the outside of the structure. Use non-hardening caulk, putty, or insulation.
3.Avoid locations such as near dryer vents or placing the sensor close to, or directly above the outdoor unit where it would be exposed to hot discharge air from the condenser fan.
4.Maximum length of field wiring cable to sensor is 200 feet.
5.Minimum wire gauge is 18AWG.
Mounting and Wiring
1.Turn OFF all power to heating and cooling equipment.
2.If an existing thermostat is being replaced: a. Remove existing thermostat from wall.
b.Disconnect wires from existing control, one at a time. Be careful not to allow wires to fall back into the wall.
c.As each wire is disconnected, record wire color and terminal marking.
d.Discard or recycle old thermostat.
Mercury is a hazardous waste and MUST be managed properly. If the Comfort Control is replacing a thermostat that contains mercury in a sealed tube, do not place your old thermostat in the trash. Contact your local waste management authority for instructions regarding recycling and the proper disposal of an old thermostat.
3.Separate the control from the mounting base to expose mounting holes by pressing the release button A on the bottom of the control with the thumb of one hand while gripping the subbase by the mounting holes with the other hand. Lift out and up. See Figure 1.
4.Slide the mounting base drawer out to expose all the mounting holes. Route control wires through the large hole in mounting base.
Level mounting base against wall (for aesthetic value only) and mark wall through 2 mounting holes. See Figure 2.
5.Drill two mounting holes in wall where marked.
6.Secure mounting base to wall with 2 screws (use anchors provided if needed). Additional mounting holes are available for more secure mounting if needed.
Make sure all wires (including the 2 outdoor sensor wires) extend through hole in mounting base.
7.Adjust length and routing of each wire to reach proper terminal on the connector block on mounting base. Strip only 1/4-in. of insulation from each wire to prevent adjacent wires from shorting together when connected.

8.Match and connect control wires to proper terminals on the connector block. (See the following wire diagrams).
9.Push any excess wire back into the wall and seal the hole to prevent air leaks.
Note: Air leaks in the wall behind the control can cause improper operation.
10.Check the operation of the business card drawer. Verify that it slides in and out without binding.
11.Reinstall the control on its mounting base by aligning the control at the top of the mounting base. Swing the control downward and gently press the bottom of control into position until latch button A engages. See Figure 1.
12.Turn ON power to the heating and cooling equipment.

Enter USER Setup:
(See Table 3A, steps 50-62 for option details) Press and hold Mode and Fan at the same time.
Note: Allow a minimum of 5 seconds after saving selections (Step 99 - SA) for the control to write selections to memory. If power is lost or removed prior to the 5 second elapsed time, the selections may be lost and must be reentered. If the SERVICE icon is flashing on the control LCD, press any key and check / re-enter setup choices.
Keypad Navigation:
Use the Mode and Fan buttons to navigate forward and backward through the configuration and Manual Test Mode steps.
Press Mode to advance forward to the next step.
Note: Dual Fuel Applications. When the
system type is HP and the Indoor Heater Type is Gas or Oil (Dual Fuel System) the JP1 jumper on the PCB must be cut.

There are two methods of verifying that the Comfort Control operates the system as intended.
Method 1: Normal Mode
This can be accomplished by pressing the appropriate keypad button(s) to cycle the system through each of the available modes and increasing or decreasing the setpoint to activate and deactivate the cycle.
The minimum on and off cycle time delays, selected during the setup, will be enforced. Press the appropriate keypad button for the filter timer, outdoor temperature display and energy savings features to verify they are set to the end user’s desired preference.
Method 2: Manual Test Mode
The Comfort Control’s load outputs can be verified using the manual test mode. See Table 1 for navigating through the manual test mode steps.
To Enter The Manual Test Mode:
1.) Set System Mode to OFF
2.) Set Fan to AUTO
3.) Press and hold Mode and Down Arrow at the same time.
The Manual test mode will time out and return to normal operation after 4 minutes from the last key press.
NOTE: The manual test mode allows the installer to energize the G fan relay, Table 1, Step 70, and then advance to Step 72 to energize the Y compressor output with the fan still operating. It is recommended that this method be used to prevent damage to the compressor.
