K. ADDITIONAL SAFETY FUNCTIONS
1. Ignition Failure Protection: The Peak control allows for 3
failed ignition attempts before the control goes into a lockout
state showing Loc 1. This lockout can be reset by holding the
Menu button until “rst” appears on the display or by pressing
the manual reset button below the control state LED on the
main control board.
2. Flame Failure Protection: The Peak control allows monitors
for flame failure during a demand. If the flame signal is lost
more than 3 times during a single demand the control will go
into a lockout state showing Loc 22. This lockout can be reset
by holding the Menu button until “rst” appears on the display
or by pressing the manual reset button below the control
state LED on the main control board.
3. Flue Temperature Protection: The Peak control monitors
the flue temperature sensor for high temperatures. If the flue
temperature approaches 190°F (88°C), the boiler will begin
to modulate input down regardless of setpoint or demand. If
the flue temperature reaches 190°F (89°C) the boiler will shut
down and run the blower for 5 minutes before re-ignition.
4. Flame Recovery: The Peak control actively monitors the
ionization current though the flame sensor. If Flame Signal
drops to below 1.5 μA, the control will increase the minimum
fan speed in order to attempt to maintain flame signal. If this
fails, the control will retry with a further increased minimum
fan speed. If a second flame loss occurs, the control will retry
again at ignition fan speed as the minimum. If at any point
the demand is met the control will reset the minimum fan
speed to default.
5. Stayburn and Startburn Temperatures: When the supply
temperature of the boiler exceeds the maximum boiler
setpoint due to the off hysteresis of 9°F and a demand is still
present, the Peak control allows the unit to run at 1% input
until the Stayburn temperature is reached at 190°F (88°F).
The boiler will always shutdown at this temperature and will
never exceed it. The Peak is not designed to run beyond this
temperature. Steps should be taken to improve the system
to lower the required setpoint if the Stayburn Temperature is
ever reached. The boiler will not re-ignite until the Startburn
temperature is reached below the setpoint. The Startburn
Temperature is 185°F (85°C).
BOILER CONTROL: INTERNAL WIRING & OPERATION
6. Frost Protection: The Peak control monitors the unit for
potential freeze situation which would cause damage to the
internal piping of the unit. If the water temperature inside the
unit falls below 41°F (5°C) the boiler pump will start. If the
temperature continues to fall the burner will ignite to and heat
the unit until the supply temperature reaches 59°F (15°C).
7. Filling Protection: The Peak control monitors the system
pressure for drops below the required system pressure of
11.6psig. Pressures below 17.5 psig will cause the pressure
display on the unit to flash as a warning. Pressures below
10.15 psig will cause the boiler to shut down and display a
“FILL” error. The unit will not run until the pressure is again
above the minimum pressure
8. De-air: Upon boiler power initiation, the Peak control
will enter a de-air state during which it will purge any air
remaining in the system by cycling the pump on and off and
changing the position of the switching valve. This period lasts
for 4 minutes. It can be canceled by holding buttons L2 and
R2 for 3 seconds simultaneously.
9. Low Water Cut Off: The Peak control comes equipped with
a probe style LWCO function built into the control. With
the addition of the optional LWCO probe kit installed in the
piping above the boiler, the control will monitor for low water
conditions. If such a condition occurs the control will go into
a lockout state and must be manually reset.
10. Flue Pressure and Block Condensate Switch: The Peak
control monitors a pressure switch that will enter the boiler
into a blocking state. This switch will display Err 156.
Clearing of the flue or condensate line will automatically
clear this error.
