D. The burners will ignite and the control will receive a
signal from the flame sensor.
E. The spark ignitor will remain active for the duration of
the ignition cycle, regardless of flame status .
5 .
If flame is not established during the ignition cycle, the
control will repeat the pre-purge and ignitions cycles up to
three times. After three failed ignition attempts, the
board will enter a 1 hour lockout.
6 .
Once flame has been established, the control will enter a
warmup period to ensure flame stabilization and reduce
condensation in the heat exchanger.
7 .
After the warmup period, the control will enter the run
cycle. During the run cycle, the burner firing rate and
draft inducer pressure are determined based on the heat
demand received by the control via a Modbus signal or the
analog thermostat.
Note: If the control is paired with a split manifold,
steps 1 through 6 pertain to the primary burners.
Once the control exits the warmup period and
the firing rate is dictated by the rooftop control,
the control will ignite the secondary burners and
modulate the primary burners based on the demand
for heat.
8. The run cycle will continue until any of the following
conditions are met.
A. The call for heat is terminated
B. Any of the safety devices (high limit, air pressure,
rollout, etc.) are triggered
C. The control reaches it’s maximum run time of 6 hours.
If this condition is reached, the control will terminate
the run cycle, continue through the proper sequence of
operations, and then immediately enter the system check
and pre-purge cycles to prepare for re-ignition, assuming
conditions A and B haven't been met.
9 .
Once the run cycle has terminated, the redundant safety
valve will close, the modulating valve will return to its set
position, and the draft inducer will ramp up to its “light-off”
setting for a 45 second post-purge cycle.
10. After the conclusion of the post-purge, the control will
enter the “OFF” state. All system outputs are de-energized
but all safety devices are still monitored.
Altitude Conversion
For elevations up to 2000 feet, rating plate input ratings apply.
For high altitudes (elevations over 2000 ft) contact Daikin
Applied Parts . See
for part numbers. Or contact local
gas supplier to confirm gas heating value has been devalued
for applicable elevations.
NOTE:
If the fuel source has been derated for altitude by
the local utility provider then a conversion kit is not
required.
