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.
When the hydrobox is connected with a PUMY-P/SUHZ-SW outdoor unit of which maximum outlet water temperature is 55ºC, DIP SW1-2 must be changed to OFF.
*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 This switch functions only when the hydrobox is connected with a PUHZ-FRP outdoor unit. When another type of outdoor unit is connected, the
heating mode function is active regardless of the fact that this switch is ON or OFF.
*4. Space heating and DHW can be operated only in indoor unit, like an electric boiler. (Refer to “5.4 Indoor unit only operation”. )
*5. If emergency mode is no longer required, return the switch to OFF position.
*6. Active only when SW3-6 is set to OFF.
*7. Active only when SW4-1 is set to ON.
