Outing Mode (Hot Key of Wired Remote Controller)
• All the target temperatures(both water outlet and room) for space heating/cooling/
auto(water-law) modes and the target tank temperature for DHW heating mode will be
changed to the values defined in the table above to save energy consumption during the
vacancy of house.
With the lowered target temperatures(FSV #5011 ~ #5019), the system will be operated
normally.
Economic DHW Heating
• Which is heat pump only, saving energy consumption. A target temperature of DHW shall be
lowered as much as Users set with field setting values stored in wired remote controller.
- New target DHW tank temperature will be the value subtracted the difference(#5021) from
the present user’s setting.
TDM(Time-Division Multi) Variables
• 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 and 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.
• A2A maximum operation time: FSV #5031(Default “30 min.”, Range 5 ~ 60 min.), After
this 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.
• A2W minimum operation time: FSV #5032(Default “3 min.”, Range 0 ~ 10 min.), in this
minimum time, the outdoor machine will operate only for A2W, even though there are no
more A2W’s continuous operation demands.
