NOTE
The following wiring diagrams show typical terminal identification and wiring. For proper installation, refer to the original manufacturer's instructions.
Relay contacts shown are thermostatically operated.
Typical wiring diagram for single transformer systems
This diagram illustrates the connections for a single transformer system. It shows the Thermostat Control Circuit terminals (Y, Y2, G, W, W2, C*, R) connected to various HVAC components: Compressor Contactor Stage 1 and Stage 2, Fan Relay, and Heat Relay Stage 1 and Stage 2. A 24 VAC transformer provides power, with connections for Hot and Neutral, feeding into the system. The diagram also indicates a 120 VAC input to the transformer. A note specifies that the 24 Volt neutral connection to terminal C on the thermostat is not required if batteries are replaced annually with fresh "AA" Energizer® alkaline batteries.
Reset Operation: 1F81-261
If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the thermostat by pressing the ⬆️ and ⬇️ buttons and TIME at the same time. This also resets the factory defaults to the configuration menu and program. If the thermostat has power, has been reset and still does not function correctly, contact your heating/cooling service person or place of purchase.
Typical wiring diagram for two-transformer systems with NO safety circuits
This diagram depicts the wiring for a two-transformer system without safety circuits. It features a "CUT AND TAPE OFF!" instruction for the 120 VAC transformer's neutral wire. Similar to the single transformer diagram, it shows the Thermostat Control Circuit terminals (Y, Y2, G, W, W2, C*, R) connected to Compressor Contactor Stage 1 and Stage 2, Fan Relay, and Heat Relay Stage 1 and Stage 2. The diagram also includes the note "TWO COMMONS MUST BE JUMPERED TOGETHER!". It also reiterates the note regarding the 24 Volt neutral connection to terminal C and Energizer® batteries.
Reset Operation: 1F83-261
If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the thermostat by pressing the ⬆️ and ⬇️ buttons and moving the SYSTEM switch from OFF to HEAT at the same time. This also resets the factory defaults to the configuration menu. If the thermostat has power, has been reset and still does not function correctly, contact your heating/cooling service person or place of purchase.
