Startup & Operation (continued)

Power ON Open all manual oil line valves. Close the line switch. (If Red LED turns on constant , control is in lock-

out. See next page to reset.)

Self-test 1 The control performs a “boot-up” test to verify internal operation each time power is applied to the L1 wire.

The amber LED turns on and the test continues for about 5 seconds. If the test fails, the control turns the

amber LED off and repeats this test sequence until successful.

Stand-by (No call for heat) If Self-test 1 is successful, amber LED turns off and control waits for heat call.

Call for Set thermostat to call for heat. Thermostat circuit must be closed and black wire must receive

heat power from the limit circuit.

Self-test 2 If a failure occurs in this self-check, the control won’t start and the amber LED blinks 1 second on, 4

seconds off, until serviced or the problem clears. These failures include CAD cell seeing light, valve lead

voltage on too early, internal fault, or line voltage <90 V. See service section.

Burner on After the self-test, amber LED turns off. The ignitor starts, followed 2 seconds later by the motor.

Valve delay The oil valve opens after the valve delay-on period (pre-purge). (For oil valve delay on operation, wire oil

ON valve to the violet lead. If not using an oil valve, cap the violet lead to automatically disable pre-purge and

post-purge).

Pump To enter pump prime: 1. Start a CFH cycle. During Pre-Ignition or Valve Delay On, press Reset until motor

Prime turns off (10 seconds), then release the button. When motor turns back on, within 5 seconds, press the Reset

button until the amber LED starts to ash. You are in Pump Prime, release Reset button.

Optional Pump Prime notes: 1) If lost, press Reset for 1 second and release, then if the control is not in

Pump Prime, restart the sequence. 2) If Reset is released before end of rst 10 seconds, the control re-

turns to Standby and restarts another CFH cycle. 3) If reset is not pressed the second time, a normal CFH

cycle will continue. 4) If motor and igniter are on and amber LED is ashing, the control is in Pump Prime.

5) Pump Prime will exit standby if ame is detected, or 60 seconds has elapsed, or loss of TT or Limit, or

Reset button is pressed.

Bundled Neutrals Can Be Attached to Any L2 Terminal

IMPORTANT: Reduce Motor Load by Valve Load

Latch-Up:

Prevents excessive resets by locking out after 3

consecutive resets during any one call for heat.

To reset from Latch-Up:

1. Depress and hold the red button. Amber light will

blink after 10 seconds, red light will stay on solid.

2. After amber light stops blinking (approximately

20 seconds), release red button.

Releasing red button during step 1 and 2 will result

in the control returning to latch-up
