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.

Note: *1 The switch must be turned OFF when the maximum output of heater (5.5 kW) is necessary.
*2. OUT11 will be available. For safety reasons, this function is not available for certain errors. (In that case, system operation must be stopped and only
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.
