DESCRIPTION
•
MUST be set to correct model.
• Check the boiler model against the model listed on the boil-
er's rating plate. Change the selection to the correct model if
not. Also verify the model number on the
display at power-up. Failure to correct would result in severe
personal injury, death or substantial property damage.
•
Select single, master or shadow.
•
MUST be set to correct value if altitude over
2,000 feet
• If boiler outlet water temperature exceeds this temperature,
the SlimFit control will shut down the boiler and enter lock-
out. Changing this setting is NOT recommended.
• WWSD stands for warm weather shutdown. It means the
boiler will not be allowed to fire if the outside temperature is
greater than the WWSD setting.
When the boiler is kept off because the outside temperature is
above WWSD, the graphic display will show WWSD, and the
boiler will remain in standby until the outside temperature
drops below WWSD temperature.
WWSD does not apply to DHW systems.
The outdoor sensor must be installed to use this function.
Any setting other than OFF will cause the control to look for
a sensor. It will display an error if a sensor is not detected.
• Use this setting to calibrate the outdoor sensor when needed
to compensate for variations in lead length or other factors
that could affect total resistance in sensor circuit.
• For each circulator, select whether you want the control to
automatically start the circulator and run for 10 seconds for
each 72-hour period of inactivity.
• This function automatically starts the circulators chosen if the
heat exchanger sensors detect a temperature less than 45°F. In
addition, the burner is turned on if temperature drops below
40°F. Circulators and burner turn off when the temperature
rises above 48°F.
• Use this function to restore all control settings to factory
default values — will require complete restart and setup of
control after resetting. Record information from the MAIN-
TENANCE screen and any history information that may be of
use in the future. ALL stored data is eliminated when reset to
defaults, except for boiler model number.
