Emerson 1F83-277 Check Thermostat Operation, Multi-Stage Terminal Outputs

Multi-Stage Terminal Outputs

Refer to equipment manufacturers' instructions for specific system wiring information.

You can configure the thermostat for use with either multi-stage electric heat systems or multi-stage gas systems. When config- ured for electric heat, the G terminal (blower/fan) will be energized on a call for heat.

This thermostat is designed to operate a single-transformer system. If you have a two-transformer system, cut and tape off

one transformer. If transformer safety circuits are in only one of the systems, remove the transformer of the system with NO safety circuits. If required, replace remaining transformer with a 75VA Class II transformer. After disconnecting one transformer, the two commons must be jumpered together.

Use the terminal output information below to help you wire the thermostat properly for your multi-stage system. After wiring, see CONFIGURATION section for proper thermostat configu- ration.

CHECK THERMOSTAT OPERATION

NOTE

To prevent static discharge problems, touch side of thermostat to release static build-up before touching any keys.

If at any time during testing your system does not operate properly, contact a qualified service person.

Fan Operation

If your system does not have a G terminal connection, skip to Heating System.

1.Turn on power to system.

2.Move FAN switch to ON position. The blower should be - gin to operate.

3.Move FAN switch to AUTO position. The blower should stop immediately.

!CAUTION

Do not allow the compressor to run unless the com- pressor oil heaters have been operational for 6 hours and the system has not been operational for at least 5 minutes.

Heating System

1.Press SYSTEM button to select the Flame icon (). If the auxiliary heating system has a standing pilot, be sure to light it.

2.Press to adjust thermostat setting to 1° above room temperature. The heating system should begin to operate. The display should show “STG1”. However, if the setpoint temperature display is flashing, the compres- sor lockout feature is operating (see Configuration menu, item 5).

3.Adjust temperature setting to 3° above room temperature. If your system configuration is set at MS2, HP2 or HP1, the auxiliary heat system should begin to operate and the display should show “STG1+2”.

4.Press to adjust the thermostat below room tempera- ture. The heating system should stop operating.

Emergency System

EMER bypasses the Heat Pump to use the heat source wired to terminal E on the thermostat. EMER is typically used when compressor operation is not desired, or you prefer back-up heat only.

1.Press SYSTEM button to select EMER. “EMER” will flash on the display.

2.Press to adjust thermostat setting above room temperature. The Aux. heating system will begin to operate. The display will show “STG1” flashing “EMER”

and Flame icon () to indicate that the Aux. system is operating.

3.Adjust temperature setting to 3° above room temperature. The auxiliary heat system should begin to operate and the display should show “STG1+2”.

4.Press to adjust the thermostat below room tempera- ture. The Aux. heating system should stop operating.

!CAUTION

To prevent compressor and/or property damage, if the outdoor temperature is below 50°F, DO NOT operate the cooling system.

Cooling System

1.Press SYSTEM button to select the Snowflake icon ().

2.Press to adjust thermostat setting below room temperature. The blower should come on immediately on high speed, followed by cold air circulation. The display should show “STG1”.

3.Adjust temperature setting to 3° below room temperature. The second stage cooling should begin to operate and the display should show “STG1+2”.

4.Press to adjust the temperature setting above room temperature. The cooling system should stop operating.
