OPERATIONAL GUIDE
Pre-Purge Delay – 15 seconds on delay
LED Codes – Flashing 1/2 second on / 1/2 second off – system is locked out or in restricted mode
(hard lockout).
– Flashing 2 seconds on / 2 seconds off – control is in recycle mode (soft lockout).
– ON – CAD cell is sensing flame
– OFF – CAD cell is not sensing flame.
Future Option – Flame Quality Monitor
This control is trained to recognize and remember
a good flame based on initial burner set up.
Control then monitors the flame via the CAD cell
signal for deviation in the combustion
characteristics of the burner. If the control senses
a deviation on the high side or on the low side
from the original set up condition for three
consecutive cycles, it will trigger an alarm circuit
which can be tied to an audible local device to
signal the home owner or into the home security system. Upon being notified of the of the alarm,
the security agency will notify the dealer of choice
based upon information supplied by the home
owner. The system will also be capable of being
connected to a phone line that will contact the
dealer directly with the alarm. This alarm will
typical sound 3 to 5 days prior to the primary
control going into lockout giving the service
agency a prior notice before a sooting condition or
other failure can occur resulting in untold savings.
Ignition Trials – On any given call for heat the
control will allow three ignition trials. After the
three trials the control will go into a soft lockout
mode. The LED will flash 2 seconds on and 2
seconds off when in this recycle mode. The
control may then be reset by pressing the RED
reset button on the control. If within the same
original call for heat the control will again allow
three ignition trials followed by another soft
lockout and a 2 second on / 2 second off LED
code. The control my be reset one additional time
by pressing the red reset button. This will allow three final ignition trials. If all three of the final
ignition trials fail then the control goes into a hard
lockout or Restricted Mode. This series of ignition
failures must all occur with the original call for
heat in order to reach the Restricted Mode. The
LED will now flash 1/2 second on / 1/2 second off
indicating the restricted mode. The control can be
resurrected from the restricted mode only by
pressing and holding the red reset button for
approximately 30 seconds until the LED flashes
twice. Removing unit power or resetting the
thermostat will not reset the control
Checking CAD Cell – With a call for heat and the burner ignited, press and release the red reset button.
The LED will go out and then flash 1, 2, 3, or 4 times before returning to the run mode. The CAD cell
resistance must be below 1600 ohms for proper operation.
– 1 flash – Less than 400 ohms
– 2 flashes – More than 400 and less than 800 ohms
– 3 flashes – More than 800 and less than 1600 ohms
– 4 flashes – More than 1600 and less than 5000 ohms
