Hi all,

At page 20 of WHO=4 documentation related to DIM=19 “VALVE STATUS” I found:

CV, HV = 0 –> OFF

CV, HV = 1 –> ON

CV, HV = 2 –> Opened

CV, HV = 3 –> Closed

CV, HV = 4 –> Stop

CV, HV = 5 –> OFF Fan Coil

CV, HV = 6 –> ON speed 1

CV, HV = 7 –> ON speed 2

CV, HV = 8 –> ON speed 3

I have a fancoil system, T(set) = 20°, T = 21° (so fancoil is off) in Heating Mode.

If I send *#4*where*19## I get *#4*where*19*5*14##

CV=5 looks good, I’m in heating mode and 5 means “OFF Fan Coil”. But what about HV=14? does anyone know anything related to this value (and / or other not documented)?

If I put the thermostat in protection mode or in OFF I get *#4*where*19*5*5## so it seems that 5 means OFF when protection/off and 14 means OFF when request temperature is lower than current temperature ( HEATING mode).

Hello Andrea,

Here is a complement of information given by MyHOME team :

CV, HV = 15 –> OFF speed 2

CV, HV = 16 –> OFF speed 3

Have a good day,
