Notes:
*1. When the cylinder unit is connected with a PUMY-P and PXZ 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
en
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 connected, 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". )
*6. If emergency mode is no longer required, return the switch to OFF position.
