APPENDIX C - SEQUENCE OF OPERATION AND TROUBLESHOOTING

Table C-1: 1158-120 Electronic Fan Timer Board (EFT)

Detailed Sequence Of Operati

Mode

Action

System Response

HEAT

Thermostat calls for heat. ("W"

terminal is energized).

EFT closes the oil primary control T - T connections.

Ignition system and the oil primary control start the furnace. Oil flows as long as the oil

primary control senses flame.

Burner motor is energized and heat "fan on" delay timing begins. When timing is complete, the

circulator fan is energized at heat speed.

Thermostat ends call for heat.

("W" terminal is de-energized).

The oil primary control is de-energized, terminating the burner cycle.

Heat "fan off" delay timing begins. Length of delay depends on EFT dipswitch settings. When

timing is complete, the circulator fan is de-energized.

EFT returns to standby mode, (Oil primary control and circulator fan are off, unless continuous

fan operation is selected at the thermostat).

Burner fails to light.

Oil primary control locks out within lockout timing, (15 seconds).

Burner motor is de-energized. (Even though thermostat is still calling for heat).

If circulator fan has started, it continues through the selected heat “fan off” delay period.

Established flame fails.

Burner motor is de-energized and oil primary control goes into recycle mode.

If the selected heat “fan off” delay timing is longer than the recycle delay timing, the circulator

fan continues to run through the next trial for ignition.

COOL

Thermostat begins call for

cool. (G and Y terminals are

energized).

Cooling contactor is energized immediately.

Circulator fan is energized at cool speed.

Thermostat ends call for cool.

(G and Y terminals are de-

energized).

Cooling contactor is de-energized immediately.

Circulator fan turns off immediately.

FAN

Thermostat begins call for fan. (G

terminal is energized).

Circulator fan is energized immediately at cooling speed.

Thermostat ends call for fan. (G

terminal is de-energized).

Circulator fan is de-energized immediately.

LIMIT

Limit switch string opens.

Oil primary control shuts off burner.

Circulator fan is energized immediately at heat speed.

EFT opens the oil primary control T - T connections. Circulating fan runs as long as limit string

stays open.

If there is a call for cooling or fan, the circulating fan switches from heating to cooling speed.

Limit switch string closes (with

existing call for heat).

EFT begins heat “fan off” delay sequence.

Circulating fan turns off after the selected heat “fan off” timing.

EFT re-closes the oil primary control T - T connections.

Oil primary control is energized, initiating burner light off.

Limit switch string closes

(without existing call for heat).

Circulator fan turns off when heat “fan off” delay time is complete.

Normal operation resumes; EFT control is in standby mode awaiting next thermostat

command.

FAN

Continuous circulating fan is

connected.

Circulating fan is energized when there is no call for heat, cool, or fan.

If fan operation is required by a call for heat, cool, or fan, the EFT switches off the continuous

fan speed tap before energizing the other fan speed.

EAC

Electronic Air Cleaner is

connected.

Electronic air cleaner (EAC) connections are energized when the heat or cool speed of the

circulator fan is energized. EAC connections are not energized when the optional continuous

fan terminal is energized.

HUM

Humidity control is connected.

Humidifier connections are energized when the oil burner motor is energized.
