ADJUST Menu
The ADJUST menu has most of the adjustable parameters that determine heater and system
operation (four others are found in Boiler 1 screen
– Outlet Max, Mass, Post Purge and MOD min %).
Each adjustable parameter has a small bar on top of or beside the parameters value; a green bar
indicates a confirmed (saved) value, whilst a red bar means that the value displayed is different from
the actual saved value.
Note: If changing a parameter value and the SET button is not tapped within 5 seconds, the value will
revert to the previously saved value and the bar will change back to green.
•
ADJUST menu parameters can only be adjusted/changed when VERSA control board DIP switch 1
is set to ON (up).
Always isolate power before changing DIP switch settings.
•
Some parameters may or may not be available depending on PIM and VERSA control board DIP
switch settings.
