WARNING

1. Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage.
2. All units must be wired strictly in accordance with wiring diagram furnished with the unit. Any wiring different from the wiring diagram could result in a hazard to persons and property.
3. All wiring must be done with a wiring material having a temperature rating of at least 105°C.

important

1. The use of this manual is specifically intended for a qualified installation and service agency. All installation and service of these kits must be performed by a qualified installation and service agency.
2. These instructions must also be used in conjunction with the Installation and Service Manual that originally shipped with the appliance, in addition to any other accompanying component supplier literature.

Installation and Wiring

Installation of wiring must conform with local building codes, or in the absence of local codes of the National Electric Code ANSI/NFPA 70 – Latest Edition. The unit must be electrically grounded in conformance to this code. In Canada, wiring must comply with CSA C22.1, Part 1, Electrical Code.

Wiring Diagram Selection

• For gas-fired unit heaters and duct furnaces (non-factory supplied blower) with model numbers shown above, refer to Figure 1.1 and Table 1.1 for correct unit-to-thermostat wiring.
• For all other system units (factory-supplied blower), refer to the job-specific unit wiring diagram provided with the unit.
• For deviations to these wiring diagrams or the job-specific wiring diagrams, consult the factory.

1. Not all terminal connections are used. The table only shows terminals that are used for required heating operation.
2. The factory-installed R to Rc terminal wire jumper is to remain in place.
3. Verify that the bus bar on the G terminal is removed.
4. Verify that the bus bar between the T2 and F terminal is removed.

Thermostat Function Program Selection

• To enter thermostat setup mode, press and hold the s and FAN buttons until the display changes to setup mode. Use the s and t buttons to change settings, the NEXT button to advance to the next setting, and the DONE button to save the settings and exit from the setup mode.
• For gas-fired unit heaters and duct furnaces (non-factory supplied blower) with model numbers shown on the opposite side, refer to Table 2.1 for typical thermostat function settings.
• For all other system units (factory-supplied blower), refer to the job-specific unit wiring diagram provided with the unit.
• For deviations to these wiring diagrams or the job-specific wiring diagrams, consult the factory.
• For additional information, refer to the vendor literature supplied with the thermostat.
