Precautions

  • Do not exceed the specification ratings.
  • All wiring must conform to local and national electrical codes and ordinances.
  • This control is a precision instrument, and should be handled carefully. Rough handing or distorting components could cause the control to malfunction.

Emerson 1F83H-21PR Battery Location

  1. W2/E Jumper Wire This thermostat electrically connect the W2 and E terminals so that you do not need to do this with a jumper wire. If your system has separate W2 and E wires, clip the W2/E jumper located on the back of the thermostat. This will isolate both terminals so they can be used independently.
  2. O/B Terminal Switch The O/B switch on this thermostat is factory set to the O position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in Cool. If the heat pump being installed requires a B terminal to energize the changeover relay in Heat, the O/B switch must be moved to the B position.

Symptom

Possible Cause

Corrective Action

No Heat/

No Cool/

No Fan

(common problem)

  1. Blown fuse or tripped circuit breaker
  2. Furnace power switch to OFF
  3. Furnace blower compartment door panel loose or not properly installed
  4. Loose connection to thermostat or system
  1. Replace fuse or reset breaker
  2. Turn switch to ON
  3. Replace door panel in proper position to engage safety interlock or door switch
  4. Tighten Connections

No Heat

  1. System Switch not set to Heat
  2. Loose connection to thermostat or system
  3. Heating System requires service or thermostat requires replacement

Verify thermostat and system wires are securely attached.

Diagnostic: Set System Switch to Heat and raise the setpoint above room temperature. Within five minutes the thermostat should make a soft click sound and “Heat On” should appear on display. This sound indicates the thermostat is operating properly. If the thermostat does not click, try the reset operation listed below. If the thermostat does not click after being reset, contact your heating and cooling service person or place of purchase for a replacement. If the thermostat clicks, contact the furnace manufacturer or a service person to verify the heating system is operating correctly.

Symptom

Possible Cause

Corrective Action

No Cool

  1. System Switch not set to Cool
  2. Loose connection to thermostat or system
  3. Cooling System requires service or thermostat requires replacement

Verify thermostat and system wires are securely attached.

Diagnostic: Set System Switch to Cool and lower setpoint below room temperature. Same procedures as diagnostic for “No Heat” condition except set the thermostat to Cool and lower the setpoint below the room temperature. There may be up to a five minute delay before the thermostat clicks in Cooling if the compressor lock-out option

is selected in the installer menu. (see INSTALLER MENU, item 50)

Heat, Cool or Fan Runs Constantly

Possible short in wiring, thermostat, heat, cool or fan system

Check each wire connection to verify they are not shorted or touching other wires. Try resetting the thermostat. If the condition persists contact your HVAC service person.

Thermostat

Thermometer

Disagree

Thermostat display requires adjustment

Display can be adjusted +/-5°. See User Menu item 04

Furnace (Air

Conditioner)

Cycles Too Fast or Slow (narrow or wide temperature swing)

The location of the thermostat and/ or the size of the Heating System may be influencing the cycle rate

Digital thermostats provide precise control and cycle faster than older mechanical models. The system turns on and off more frequently, but runs for a shorter time. If you would like to increase cycle time, choose SLO for slow cycle in the Installer menu. (Reference menu items 30 & 35) If an acceptable cycle rate is not achieved, contact your HVAC service person.

“Call for Service” icon appears on displayed

  1. Heating system is not able to heat the space to within 10 degrees of the setpoint within 2 hours
  2. Cooling system is not able to cool the space to within 10 degrees of the setpoint within 2 hours
  3. If “--” is displayed for the Room Temperature, a replacement thermostat is needed
  4. None of the buttons operate on the thermostat
  5. If “Call for Service” is flashing, compressor self diagnostic is detecting an issue with the

outdoor unit

  1. See corrective action for “No Heat”
  2. See corrective action for “No Cool”
  3. Replace thermostat
  4. Make sure keypad lockout is not turned on

(denoted by  icon)

  1. Contact a service person to verify the equipment is operating correctly

Resetting the Thermostat or Thermostat Settings

If the thermostat has good batteries, but has a blank display or does not respond to key presses, the thermostat should be reset by removing the batteries for 2 minutes. This reset will not change the menu settings or program. If the condition persists after reinstalling the batteries, replace the thermostat.
To conveniently reset only the schedule and user settings back to factory defaults, press Menu and Backlight buttons at the same time and hold until the display goes blank and resets.
