Set Boiler CH Target Temperature
1. Press the MODE button until the display
shows PARA. This is the parameter mode
of the control.
2. Press the STEP button until the first digit
on the display shows "4". The last three
digits on the display shows the outlet water
temperature setting (high limit).
3. Press the "+" or "-" button to change the
setting of the outlet temperature (high

If an outdoor sensor is used, then the set-
ting of the Boiler CH Target temperature
is the target temperature when the out-

Operation Verification - Space Heating
Digits and characters shown as [ 0000 ],
in the following outline, represent the
control panel display. The last three dig-
its on the display is the measured boiler
water temperature and may differ from
what is shown in the manual.
1. Refer to Set DHW Storage Temperature
outline on page 41 and set the DHW to 68
from the factory setting of 140.
2. Set the room thermostat to the lowest setting.
3. Turn off power to the boiler, wait a few
seconds and turn on power to the boiler.
4. The following displays should occur:
[ U1.22 ] Software version
[ A140 ] Self check on power up
[ 0140 ] No call for heat
If the water heater storage temperature is
below the setpoint of Parameter 1, the
boiler will operate in DHW mode until
setpoint is reach. Once the DHW mode is
complete, proceed to step 5.
5. Initiate a call for heat by raising the set
point of the room thermostat to the highest
setting. The following display should
occur.
[ 5140 ] This is a fan / air flow check. The
burner blower will be energized momentar-
ily prior to the prepurge cycle.
[ 1140 ] This is the prepurge cycle. The
boiler blower and the CH (Central Heating)
circulator become energized. The blower
has a 10 second prepurge cycle.
[ 2140 ] This is the ignition cycle. The con-
trol module will energize and open the gas
valve and begin the spark for ignition.
- If the burner flame proves the burner
will continue to fire at an ignition fan
speed for approximately 10 seconds to
stabilize the flame.
- If the burner flame is not proven the
control module will repeat the ignition
sequence. If the flame is not proven
after 5 attempts the control will lockout
and the display will show [
E-02 ]
- To verify flame failure lockout, close
the manual shut off valve on the gas
supply piping to the boiler and repeat
ignition sequence. When verification is
completed, ensure the manual shut off
valve is returned to the open position.
