After a lot of research with trial and error, i found out that there is only one usable timer solution at the moment. Only the heating setpoint can be changed in the timer settings, so we have to place a temp for heating and another for energy saving. Second the 'thermostat mode' must be set by hand to 'heat'.
The furnace setpoint is bugged, the valves use 18° and ignore what you write into.
The thermostat mode can be used for read out in blockly, but you can't write informations to change heat or econ by now.
So from the valve only one usable setpoint is left for operation
