Dear Niels,
I friend of mine has also an Ecoforest Heatpump and wants to control it via Modbus. He contacted his supplier and got the warning that when you start controlling the heatpump via Modbus the normal working of the heatpump stops and you have to control everything of the heatpump yourself. Is this true? This sounds unbelievable.
His goal is to block/allow the heatpump only to work when the electricity prices are low.
Kind regards,
Jeroen
