Note:

*) Parameter P54 is only displayed for application "2-pipe with electric heater". All temperature settings are in increments of 0.5 °C.

**) Parameters P36-37 and P50 will only appear when either X1 or X2 set to 2, the H/C changeover.

***) Parameters P35 and P44 will only appear when the application (DIP switch) set to 2 pipe 3 position.

****) Parameters related to X1 and X2 input functions are not applicable to RDF302.B.
