R/W U16
-40°-130° (0.1°C precision)
R/W U16 0=Normal (no change to DHW pump)
1=DHW pump forced off
R/W U16 Is anticondensation more important than (0=No, 1=Yes)?
Bit map:
15-5=Reserved (always 0)
4=Outlet high limit
3=Forced rate
2=Slow start
1=Delta-T limit
0=Stack limit
R/W U16 0=Disable frost protection anticondensation,
