What does it mean if [4-03] and maximum tank set point is not according to the applicable tank in Rotex RKHBH016BB3V3?
- GgraybrianSep 13, 2025
If [4-03] and the maximum tank set point on your Rotex Heat Pump don't match the tank, the tank type may have been detected incorrectly due to wrong field wiring when setting DIP switch SS2-2. Check all field wiring between the indoor unit and tank switch box. To reset, power off the indoor unit and set SS-2 to OFF. Power on the unit (it will detect no domestic hot water tank). Power off again, set SS2-2 back to ON, and power on the unit; it will then re-detect the tank type.
