Each model is shipped with the switches No.2, 3, 4 pre-adjusted as
above in the factory.
WARNING
If you want to use a “Model” for “No. of using branch(es)” HR
Unit after closing the “Closing pipe No.”, set the dip switch for
“No. of using branch(es)” HR Unit.
Ex) If you want to use a PRHR083 for 4 branches HR Unit after
closing the 5~8th pipes, set the dip switch for 4 branches HR
Unit.

SW01C (Rotary S/W for addressing HR unit)
Must be set to '0' when installing only one HR unit.
When installing multiple HR units, address the HR units with sequen-
tially increasing numbers starting from '0'.
Maximum 16 HR Units can be installed.
Ex) Installation of 3 HR units
SW01B/SW01C/SW01E/SW02B
(Dip S/W and push S/W for Manual pipe detection)
- Set the address of the valve of the HR unit to the central control ad-
dress of the connected indoor unit.
- SW01E: selection of the valve to address
SW02B: increase in the digit of 10 of valve address
SW01B: increase in the last digit of valve address
SW01C: Manual addressing of zoning indoor units (use for Zoning
setting)
- Prerequisite for Manual pipe detection : central control address of
each indoor unit must be preset differently at its wired remote con-
trol.
