Thanks for the PR, just one small comment from my side.

What does this option mean? Is it not a preset?

[Martidjen]

Hi.
This option is not a preset, it is used to let the set_temperature option send a different command to the opentherm gateway. Temporary will use the TT= command, constant will use TC=. People familiar with the opentherm gateway will (or should) know these commands. These commands are both included in the pyotgw library, but only TT= was used until now.

When Temporary Setpoint Override Mode is set to on, the thermostat will be able to cancel the setpoint override after a program change. When the option is set to off, the Setpoint Override Mode will be ‘Constant’ and a manual temperature adjustment on the thermostat is needed to cancel the setpoint override.

Am I making any sense? :-)
