3. SW01M/SW03M/SW04M (Dip S/W and tact S/W for manual valve addressing)
- Used in manual addressing of the valve in the HR unit
- Set the address of the valve of the HR unit to the central control address of the connected indoor unit.
- SW01M: selection of the valve to address

SW04M: increase in the last digit of valve address
- Prerequisite for manual valve addressing : central control address of each indoor unit must be preset differ-
ently at its wired remote control.
