Our client wanted to change ventilation speeds from the thermostat. Ventilation runs on Modbus everything else is on KNX bus.
This may be a really stupid question but... i found that when i put a value for 1byte in bOS 1 then KNX sees it as 3 and value 2 as 5. But in bOS it shows the correct values. Ventilation has 3 speeds that we control (0 is for away, 1 is home, 2 is guests) I made some screenshots.
Shows as correct value in bOS
But in KNX sees it as 3 and value 2 as 5 in knx
Is this normal or am i missing something?
I got it working though by changing the values in the Thermostat to 3 and 5, there is no problem with value 0 :) . So now every thermostat shows the correct status and from every thermostat they can change the ventilation speeds. But I find it weird that it changes the values like that.
