fault
will go into a hold condition and will shut off the burner until the sensor or wiring is
repaired.
Hold 95
Stack sensor fault Standby The stack sensor is used as a stack high limit safety. If the sensor wiring is broken, the
stack temperature reading on the display will read
OPEN , the control will go into a hold
condition and will shut off the burner until the sensor or wiring is repaired.
918
o
F Outlet
or
918ºF Stack
Standby Whenever the display shows 918ºF for the outlet or stack temperature, it will also show
Hold 92 or Hold 95 . The control knows that a sensor is connected, but there is something
wrong with the sensor. For example, if a single thermistor and a jumper are connected to
a dual thermistor input, the control will display 918ºF and will go into the Hold condition
until the situation is corrected. To correct the 918ºF error, replace the sensor with the
appropriate dual thermistor sensor.
NOISY Standby The temperature sensors for the supply, return, stack, and outdoors are continually
monitored by the Sola. If there is something wrong with a sensor, the display will post a
message, such as
Noisy , Open or Short . Almost always, any kind of message about a
sensor means the sensor should be replaced as soon as possible. Any message about
the supply sensor requires immediate replacement.
Alert 248
No effect If the Sola boiler control is configured for a wired outdoor temperature sensor, but no
sensor is connected, then the display will show
Alert 248 . The boiler control will run fine
without an outdoor temperature sensor. To eliminate this unimportant alert, change the
Sola boiler control configuration to not expect an outdoor temperature sensor, and then
the alert will no longer be displayed.
FLASHING LIGHT ON THE MANAGER
A flashing light on the temperature bar graph (the 85
o
F bar) on the Manager indicates that the Manager can’t
communicate with the Sola. The Manager won’t be able to read the supply temperature from the Sola and the Manager
won’t be able to send circulator control commands to the Sola. The Sola will still respond to a heat demand from the
Manager when the B1-B2 dry contact relay in the Manager closes by turning on the boiler circulator and firing the burner.
Zone valves will be opened by the Manager zone outputs and heating operation will continue. The Sola will not turn on the
bronze Smart Pump for domestic hot water production unless the tank thermostat is rewired as explained in a previous
section,
ACCEL CS OPERATION WITHOUT AN OPERATIONAL CONDENSING ENERGY MANAGER .
The flashing light won’t have an effect on burner operation. However, some functions are disabled.
•
No DHW, unless tank thermostat rewired to Sola DHW demand input.
•
Smart Pump disabled.
•
Manager post purge energy recovery disabled.
•
Loop circulator disabled.
Restored connection allows normal manager operation without power reset.
Possible causes include:
•
Broken or loose wire. The wires attached to the Manager terminals labeled A and B, must be connected to the
Sola terminals labeled A and B with a sub-label of MB2.
•
The Sola may not be running, check for an illuminated power light on the Sola control.
MONITOR LIGHT ON THE MANAGER
The Monitor light will turn on after the 85ºF bar has been flashing for five minutes. The alarm relay will also change state
so the normally open contact will close. If the 85ºF bar ever stops flashing, the Monitor light will go out and the alarm relay
will change state back to normal.
PUMP EXERCISE
The Sola boiler control includes a pump exercise function. The Sola comes set for a fourteen day pump exercise interval
and a one minute pump exercise time duration. The Sola keeps track of the last time each pump has been running. After
any of the pumps has been off for fourteen days, the Sola will turn on that pump for one minute. The pump exercise
interval and the time duration can be altered using the Sola Display. Go into ‘Advanced Setup’, ‘System Config’, ‘Pump
Config’ and then select and change ‘Pump exercise interval’ and ‘Pump exercise time’. Setting the interval to zero days, or
setting the time to zero minutes, will disable the pump exercise feature.
FROST PROTECTION
The Sola boiler control includes a frost protection function. If the boiler supply (outlet) temperature drops below 40F, then
the burner will fire at minimum rate. If the boiler supply temperature then goes above 50F, the burner will turn off. The Sola
will not turn on the boiler pump and will not open any zone valves. To protect your entire system from freezing, add
antifreeze as described under ‘Winterizing’. Frost protection can be enabled or disabled by going to ‘Advance Setup’, ‘Frost
Protection Config’, then select ‘CH Frost Protection’ and select enable or disable.
