Note

1) The parameter P40 is visible only when P01 = 2.

2) The parameter P45 is visible only when P04 = 4.

3) The parameter P46 is visible only when P04 = 3.

4) The parameter P60 value 9 is visible only when P10 = 2 (Economy is supported).

5) The parameter P61 values 1 & 2 are visible only when P60 is set to DI and values 3 & 4 are visible only when P60 is set to AI. The parameter value 5 is visible only when P60 = 10.

6) The parameter P62 value cannot be set to same value as P60 (except no function, fault contact (DI), monitor (digital)) and value 9 is visible only when P10 = 2.

7) The parameter P63 is visible only when P62 ≠ 1.

13) The parameters P94, P95 and P96 are visible only when P90 = 2.

14) If parameters P90...P96 are changed, the thermostat restarts after exiting parameter setting mode to initialize the newly set application configuration.

15) This value is only for RDF440BN.

16) The parameter P96 value must be higher than all MAC addresses in the network.
