Start-Up Procedures
5. Calculate Natural gas input using the fol-
lowing equation:
3600 x 1000 / number of second recorded
for one cubic foot of gas = BTU/H.
6. The BTU/H calculated should approximate
the input rating listed on the unit.
Set Boiler CH Set Point
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 CH
Maximum Boiler Operating Setpoint.
3. Press the "+" or "-" button to change the
setting.
When an outdoor sensor is used, the set-
ting of Parameter 4 is the CH setpoint
when the outdoor temperature is at or
below 0ºF. When the outdoor tempera-
ture is above 0ºF, the PRESTIGE Solo
control will calculate the boiler setpoint
between the minimum and maximum
temperature settings.
4. Press the "STORE" button to save the setting.
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 represent the measured
boiler water temperature and may differ
from what is shown in the manual.
1. Disconnect the DHW (Domestic Hot
Water) thermostat wiring from the PRES-
TIGE Solo or turn down DHW tank aquas-
tat (if used) to ensure the boiler does not
receive a DHW call for heat.
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
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
burner 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 the 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 five attempts the control will lock-
out 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.
[ 3140 ] This is the normal CH operation
cycle. After the flame is proven and stabi-
lized the burner will fire at low input for
