Specifications

Mode of Operation

The thermostat is a programmable, manual, or auto changeover device, supporting up to 3-stage heat and 3-stage cool (depending on model). It functions with air conditioning, heat pumps, gas, oil, or electric heat systems. The thermostat activates the heating appliance when the room temperature is below the set heat temperature (by the differential temperature). When the call for heat is satisfied, outputs turn off. For heat pumps, the thermostat prevents the compressor from engaging for 4 minutes after it turns off to protect it.

When the room temperature is greater than the set cool temperature (by the differential temperature), the cooling device is activated. When the call for cooling is satisfied, outputs turn off. The thermostat also prevents the compressor from engaging for 4 minutes after it turns off to protect it.

The program schedule can be overridden by changing the set temperature using the ⬆️ or ⬇️ buttons, which initiates a temporary hold. To remove the temporary hold, press the [Home] icon twice.

Once connected to a wireless network, the thermostat can be monitored and controlled using the “Daikin i3 Thermostat app” (available for most devices).

Important Safety Information

WARNING!: Always turn off power at the main power supply before installing, cleaning, or removing the thermostat.

• This thermostat is for 24 VAC applications only; do not use on voltages over 30 VAC.
• Do not short across terminals of gas valve or system control to test operation; this will damage your thermostat and void your warranty.
• All wiring must conform to local and national electrical and building codes.
• Do not use air conditioning when the outdoor temperature is below 50 degrees; this can damage your A/C system and cause personal injuries.
• Use this thermostat only as described in this manual.

To Remove Existing Thermostat

ELECTRICAL SHOCK HAZARD – Turn off power at the main service panel by removing the fuse or switching the appropriate circuit breaker to OFF position before removing the existing thermostat.

1. Turn off power to heating & cooling system by removing the fuse or switching the appropriate circuit breaker off.
2. Remove cover of old thermostat; this should expose the wires.
3. Label the existing wires with the enclosed wire labels before removing wires.
4. After labeling wires, remove wires from wire terminals.
5. Remove existing thermostat base from wall.
6. Refer to the following section for instructions on how to install this thermostat.

To Install Thermostat

ELECTRICAL SHOCK HAZARD – Turn off power at the main service panel by removing the fuse or switching the appropriate circuit breaker to OFF position before installing new thermostat.

IMPORTANT: Thermostat installation must conform to local and national building and electrical codes and ordinances.

Note: Mount the thermostat about five feet above the floor. Do not mount the thermostat on an outside wall, in direct sunlight, behind a door, or in an area affected by a vent or duct.

1. Turn off power to heating & cooling system by removing the fuse or switching the appropriate circuit breaker off.
2. Put thermostat sub base against the wall where you plan to mount it (be sure wires will feed through the wire opening in the sub base of the thermostat).
3. Mark the placement of the mounting holes.
4. Set thermostat sub base and thermostat away from working area.
5. Using a 3/16” drill bit, drill holes in the places you have marked for mounting.
6. Use a hammer to tap supplied anchors in mounting holes.
7. Use supplied screws to mount thermostat sub base to wall (make sure thermostat wire is through hole).
8. Insert stripped, labeled wires in matching wire terminals. Tighten screws to secure wires.

CAUTION!: Be sure exposed portion of wires do not touch other wires.

9. Gently tug wire to be sure of proper connection. Double check that each wire is connected to the proper terminal.
10. Snap thermostat onto the sub base.
11. Turn on power to the system at the main service panel.
12. Configure thermostat to match the type of system you have.
13. Connect thermostat to wireless network.
14. Test thermostat operation as described in “Testing the Thermostat”.

Note: Upon Power-up the thermostat will not activate outputs for four minutes. To bypass the output lockout, change the setpoint temperature in heat or cool mode on the thermostat, by the temperature differential.

Terminal Designator Descriptions

Note 1: Not all terminals are used in every model.

Note 2: A connection to 24VAC common (C) is required.

Terminal Diagram Description: A diagram illustrates the terminal layout for the Thermostat and the Microtech III unit controller TB2, showing connections between them.

Wiring Diagrams

Installation Steps:

1. Remove cover from remote sensor housing.
2. Select an appropriate location for mounting the remote sensor.
3. Mount the remote sensor using hardware provided.
4. Install two-strand shielded wire between the S1 terminal on the remote sensor and the S1 terminal on the thermostat.
5. Install a two-strand shielded wire from the common to the SC terminal on the thermostat.
6. Configure the thermostat to work with the remote sensor.

Ordering Information:

• Remote Sensor 1
• Indoor remote sensor: 107096001
