• Under the installation of both A2A (Air-To-Air type air conditioner) and A2W (Air-To-Water type hydro
unit) at the same time, our outdoor machine can supply its full capacity to the operating indoor machines
(including A2A or A2W). If there are simultaneous operating demands from many A2A machines with A2W,
the priority of controlling the outdoor machine (ex: compressor frequency) will be given to A2A, because of
their fast response for use’s comfort. Only the remaining capacity of outdoor machine will be given to A2W
during A2A’s normal operation. In this case, it might take very long time for A2W heating, so the outdoor
machine will alternate the controlling priorities between A2A and A2W with time basis.
•
After elapsing A2A maximum time, the outdoor machine will operate only for A2W to speed up the A2W’s
heating/cooling performance, even though there are A2A’s continuous operation demands.
•
this minimum time, the outdoor machine will operate only for A2W, even though there are no more A2W’s
continuous operation demands.

– When A2W(DHW) Priority is enabled, hot water (heating) operation is given priority only if the A2A &
A2W simultaneous operation is on. Other operations are the same as when A2A Priority is enabled.
CAUTION
• While A2W is in operation, A2A does not operate. This is a normal operation.
• While A2A or A2W is not in simultaneous operation, you can use any mode without operation mode
restriction.
