System Set Up

5.1 DIP Switch Functions

The DIP switch number is printed on the circuit board next to the relevant switch-
es. The word ON is printed on the circuit board and on the DIP switch block itself.
To move the switch you will need to use a pin or the corner of a thin metal ruler or
similar.
DIP switch settings are listed below in Table 5.1.1.
Only an authorised installer can change DIP switch setting under one's own re-
sponsibility according to the installation condition.
Make sure to turn off both indoor unit and outdoor unit power supplies before
changing the switch settings.

the water circulation pump keeps running.)
*3. Space heating can be operated only in indoor unit, like an electric heater. (Refer to "5.3 Indoor unit only operation". )
*4. If emergency mode is no longer required, return the switch to OFF position.
