Modbus Climates. Different registers for read and write Set Point

Configuration

1

Hi. I’m trying to setup thermokon thanos modbus. It have different registers for read and write set point. 778 is for read current SetPoint from thanos and 1045 for write SetPoint to thanos. Currently I can read or write SP by using 778 or 1045 in target_temp_register. Is it possible to use different registers for read and write? write_register from help is not working for me.
