Eurom Sani-Wall-Heat 2000 Wifi

Hardware

I have tasmota working on my eurom but do not understand how to send the ‘set temp’ value to the heater. Can you explain in detail how to send for example 33 degrees to the heater?

edit:

I already figured it out myself. On the blakadder site it says Byte 20 - Additive checksum of bytes 2-19, this is incorrect and must be 3-19.

So to turn on the device with a temperature set to 33 degrees I use:
