Hello, question about Vitogate 200.

[Alexander123]

Hello, does anyone knows if it is possible to change a boiler mode (OFF, DHW only, DHW and Heating) throught Vitogate 200? I only found data point for for changing modes in heating circuits (HK1, HK2, HK3. )

My system is

Vitodens 200-W

B2HA (weather compensated controls)

Vitogate 7452573

gira Homeserver (with Viessmann boiler App)

many thanks in advance

Hello,

if you change the heating mode in all heating circuits to  0=Abschaltbetrieb, DHW should be deaktivated.

Otherwise you can set down the dhw-temperature at KNX-DPT  9.001

For details look here

Clever idea. Many thanks.

Do you know where I can send 0 to put boiler OFF (or in standby)? Or should I just send 0 to all HK and 0C to DHW?

Do you happen to know why Viessmann gira homeserver app doesn't allow DHW temperature to be set above 55C?

You can set at KNX-DPT 255.004

heating circuit M2 at 0x3500(Technical ID)

and M3 at 0x4500

A1 at KNX-DPT 255.002 0x2323 

You have to check if choosing "Abschaltbetrieb" only at A1 is enough. I am not sure.

You can't set DHW to 0, you can set the temperature vom 10 - 60 °C and when coding 56 : 1 is set from 10 - 90 °C . Maybe this coding can help for the temperatureproblem with your homeserver. When you want tot turn off, set to 10°C, then the boiler is off.

@Flo_Schneider Habt ihr in Bezug auf die 55°C beim Homeserver noch eine Idee? 

Many greatings
