Set the "MODE" to 1 or 2 if an outdoor Sensor is not used (1 = parallel piping, 2 = primary/secondary piping)
Caution:
"Factory" position on dip switch has to be returned to "installer" position to prevent unauthorized changes to factory settings.
*Local design input may vary from the example shown. Be sure to use design inputs for your geographical location.
EXAMPLE SETTINGS MAY VARY ACCORDING TO ACTUAL DESIGN REQUIREMENTS.

This is for DHW setpoint demand - if used
May be -20(-29) or -30F(-34) depending on area design temp.
This is used in the calculation of slope
Radiant - 130(54) Wet, 140(60) or 150F(66) for Dry system
Default 182(83) - Use "FACTORY" Dip Switch to Adjust - DO NOT EXCEED THIS MAX
Default 180(82) - Use "FACTORY" Dip Switch to Adjust. Set same as BOIL DSGN
Default 140(60) - Use "FACTORY" Dip Switch to Adjust.
Note:Some heating equipment may require a minimum water temperature - ie fan coils
Not valid for Electric Boiler application
Minimum time between firing stages
1/2 differential around target temp
Temperature drop at which next stage turns on
Time before turning on next stage
Time before turning off next stage
Minimum time stage is on before allowed to go off
Minimum time stage is off before allowed to come on
