On Thermostat, the Target temperature is limited between between 4 and 35°c

[sebglon]

For some thermostat we need to change the default Min and ma value for target temperature.
Example with hot water regulation we need to have max to 70°c
With some KNX component like the KNX OT-box we have some object that can send High and low value with 2 Bytes

But some time it can also be easy to set manual values on the component configuration
