6-9. DIP Switch Functions
The DIP switch number is printed on the circuit board next to the relevant switches.
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 cylinder unit 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
. External output (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 cylinder unit is connected with a PUHZ-FRP outdoor unit. When another type of outdoor unit is con-
nected, the heating mode function is active regardless of the fact that this switch is ON or OFF.
*5
. Space heating and DHW can be operated only in indoor unit, like an electric heater. (Refer to "5.4 Indoor unit only operation"
on the manual
of RG79F364H01
(page 19). )
*6
. If emergency mode is no longer required, return the switch to OFF position.
