AUTO RESET HIGH LIMIT
The Sola is a 24VAC boiler operating control and will modulate the burner fan speed down in 20% increments if the boiler
stack temperature exceeds 220°F and will turn off the burner if the stack temperature exceeds 230°F. The Sola will turn off
the burner altogether if the boiler supply temperature exceeds the 210°F high limit setting. The high limit setting is pre-
programmed at the factory and cannot be changed in the field.
Burner Lockout
The Sola boiler control will detect loss of flame and will attempt to restart the burner. The Sola will attempt to restart the
burner up to five times. If the flame cannot be established after the fifth restart, the boiler control will go into safety lockout.
If the boiler control is in safety lockout, the red “Alarm” light on the boiler control will turn on and the display will show
“lockout”. Make a note of any codes shown on the display, such as “Lockout 109 Ignition failed”.
The boiler control may be reset from safety lockout by pushing the reset button on the boiler control or by using the
display.
If normal operation cannot be established after ONE reset, then do not make further attempts to put the boiler back into
operation.
The boiler control tries to light the burner six times and then locks out. Pressing reset ONCE allows the boiler control to
attempt to light the burner six more times. If the burner hasn’t lit after twelve attempts, don’t continue pressing the reset
button. Instead, call for professional help from a qualified service agency.
SOLA USER INTERFACE
The Sola hydronic boiler control system provides flame supervision, hot surface ignition, circulator relays and burner fan
control for basic boiler operations. It also provides boiler status and error reporting through the display shown below. All
efficiency operations and heat demand functions are communicated directly to the Sola hydronic boiler control by the
Condensing Energy Manager. The Condensing Energy Manager may be bypassed for temporary operation using only the
Sola control to provide limited heat and hot water functions. If the black Sola boiler control fails, there is no emergency heat
option. You must obtain a replacement Sola control configured for operating the Accel CS boiler to restore operation.
