6-6. 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 need to use a pin or the corner of a thin metal ruler or
similar.
DIP switch settings are listed below in Table 6.6.1.
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.

Notes:
*1
. When the hydrobox is connected with a PUMY-P 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
. Active only when SW3-6 is set to OFF.
*4
. 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.
*5
. Active only when SW4-1 is set to ON.
*6
. Space heating and DHW can be operated only in indoor unit, like an electric heater. (Refer to "Indoor unit only operation” in page 42. )
*7
. If emergency mode is no longer required, return the switch to OFF position.
*8
. Please make sure to have necessary overheat protection on locally supplied solar thermal system side to secure safety, as the tank tem-
perature could be much higher (than current).
