Installing and wiring
Warning —
1. Always disconnect power source before wiring to avoid electrical shock or damage to the control. All wiring must comply with applicable codes and
ordinances.
2. Thermostat terminals (T–T) provide a current source. Never apply external power to these terminals under any circumstances.
Mounting
• The control may be mounted on a 4” x 4” junction box in any convenient location on the burner, furnace or wall. The location must not exceed the ambient
temperature limit, 140°F.
Wiring
• Wiring must comply with local and national electrical codes, and with the wiring diagram.
Field checks
1. Safety timing (TFI) test — Remove one cad cell wire (F-F). Start burner.
The control should lockout within the TFI time limit. Replace cad cell wire.
2. Flame failure test
as described on the reverse side of this Data sheet. The control should recycle (restart after 65 seconds).
3. If control does not operate as described, check the wiring.
Start-up & operation
Do not start the burner if the combustion chamber
contains oil or oil vapor.
The amber LED
every 3 to 4 seconds & green LED will be on or blinking.
Power ON
Open all manual oil line valves. Close the line switch.
Self-test 1 The control performs a “boot-up” test to verify internal operation each time power is applied to the black 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 heat Set thermostat and limit to call for heat. Thermostat circuit must be closed and power coming to black wire from 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, internal fault, or line voltage <90V. See service section.
Burner on After the self-test, amber LED turns off. The ignitor starts, followed 2 seconds later by the motor.
