2. SW05M Function (Rotary Switch for Addressing Heat Recovery Units).

• Rotary switch SW05M must be set to "0"' when install-
ing only one heat recovery unit.
• When installing multiple heat recovery units, address
each unit with sequentially increasing numbers start-
ing from "0".
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).
• SW04M: Increases the valve address by one (1).
Each indoor unit must have a unique, preset central control address (using its wired controller) before manual valve addressing can occur.
