Installing and Wiring
48245 control must be installed and serviced only by a qualified service technician.
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.
• Individual or bundled neutrals may be attached to any L2 terminal.
Field checks
1. Select preferred TFI by 1) leave jumper in for 45 seconds or 2) remove jumper for 15 seconds. IMPORTANT: TFI change oc-
curs on next call for heat.
2. 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.
3. Flame failure test – Start burner. After flame is established (after TFI period), close the oil supply hand valve. This will cause a
flame failure sequence as described in the Startup & Operation section of this data sheet. Under recycle, please read "Smart
Ignition" on page 3.
4. If control does not operate as described, check the wiring.
Startup & Operation
Three wire or four wire configuration
• See Figure 1 for wiring diagram for four-wire configuration
(Smart Ignition)
• See Figure 2 for wiring diagram for three-wire configuration
Do not start the burner if the combustion chamber contains oil or oil vapor.
Per UL requirements, the control will not turn on if the CAD cell senses flame during the self-test. If the CAD cell sees
light (flame) at the beginning of a cycle, the control will remain in self-test mode until the CAD cell no longer senses light (flame).
The amber LED will blink momentarily
