Addressing with Heat Recovery Units
2. SW05M Function (Rotary Switch for Addressing Heat Recovery Units).
• Rotary switch SW05M must be
set to "0"' when installing only
one heat recovery unit.
• When installing multiple heat
recovery units, address each
unit with sequentially increas-
ing numbers starting from "0".
3. SW01M / SW03M / SW04M (DIP and Tact Switches) for Manual Valve
Addressing
Non-zoning (Normal Setting).
• Set the address of the heat recovery unit valve to the central control address of the connected indoor unit.
• SW01M: Select the valve to address.
• SW03M: Increases the valve address by ten (10).
