ICECON II Configuration
The main configuration for the board is contained in the seven
check boxes located in the top right corner of the main screen.
1. ByPass System Preheat. Once checked the preheat cycle will
by eliminated. The preheat cycle will take place once main
flame has been established. The burner will be ramped to a
mid point in the firing range and remain there for
approximately 45 seconds. Once complete the output on J1-
5(usually used to energize the supply fan) will be energized.
The ICECON II controller is now ready for modulation.
2. RSP. Once checked the ICECON II controller will look for a
remote temperature dial for the temperature set point. The
remote temperature dials are available in two ranges 40–90
°
F
and 90-120
°
F. This is only used during standalone operation
and cannot be used when a building management system (BMS) or
other source is being used to provide the modulation control.
When not checked the ICECON II controller will maintain the
temperature indicated in the “Discharge Temperature” set
point box.
