Operating Sequence
With power to the control and all manual oil line valves open,
set thermostat (and limit) to call for heat. NOTE: The ther-
mostat circuit must be closed and power must be coming to
black wire from limit circuit.
Pre-Ignition
Following a 3 sec Pre-Ignition, the control advances to Valve
Delay On –
Valve Delay On
During Valve Delay On, motor starts. After set timing, valve
opens and the control advances to Trial for Ignition when the
countdown clock expires. NOTE: For the Valve Delay to oper-
ate, the burner must be equipped with a solenoid valve that is
wired to the violet terminal.
Trial for Ign
During Trial for Ignition, the CAD cell must sense flame or
the control will go into lockout. When flame is detected, the
screen will briefly display "Flame Detected" and then return
to the "Trial for Ign". When the countdown timer expires, the
control advances to Flame Stabilization
NOTE: Push View Ohms button anytime during burner opera-
tion to view the CAD Ohms reading.
Flame Stabilize
When the Flame Stabilize timer expires, the ignitor will turn
off and the burner will continue to fire until the Call for Heat
ends or the limit string opens. The screen will display "Burner
Running". Note: If Smart Ignition is selected in the Setup
Menu, the screen will alternate between "Burner Running"
and "Smart Ign Active" at any time the ignitor is running in
intermittent mode.
Burner Running
When the Call for Heat ends (or a limit control interrupts the
burner circuit), the oil valve (if installed) will turn off within
2 seconds. The motor remains on for the Motor Delay Off
period. When the Motor Delay Off timer expires, the control
returns to Standby mode awaiting the next call for heat.
