1.8.2.5 Domestic Hot Water (DHW) configuration
Setting temperature:
Setting for domestic hot water
temperature selected by the user. The
maximum value of this setting depends
on the Maximum setting temperature set
by the installer. (Between 30 to maximum
setting temperature.)
HP Control:
To achieve the DHW setting
temperature it is possible to select
between two different modes of control:
• ΔT: The most efficient way to
achieve the setting temperature.
The outlet water temperature is 15º
higher than the tank temperature,
increasing gradually until achieve
the target water outlet temperature
(setting temperature).
• Fix: This is the fastest way to
achieve setting temperature. The
outlet water temperature is set to HP
Control setting. HP Control setting
can be only adjuested in case HP
Control is Fix.
HP OFF differential temperature:
Hysteresis for the stop of DHW heating
operation with the heat pump.
HP ON differential temperature:
Hysteresis for the start of DHW heating
operation with the heat pump.
Cycle time:
Defines the minimum time between 2
heat pump cycles of domestic hot water.
DHW will be able to operate again after
wait in Thermo off the specified cycle
time.
• Range: 0 ~24 hour
• Only available in Standard mode.

Status of DHW:
• Disabled
• Enabled.
Mode: Only available when DHW heater is
activated (DSW4 pin 3 ON).
• Standard: DHW heating operation starts when
the temperature of the water in the tank is low
enough to start up the heat pump. DHW is
heated up with the heat pump or the electrical
heater (if electrical heater is enabled).
• Economic (Only for YUTAKI S Combi and H
Combi): DHW heating operation starts under
same conditions as Standard Mode with the
difference that water temperature measurement
is done at higher tank position. Due to this fact
number of DHW operations decrease and its
duration becomes longer which becomes more
efficiency.
• High Demand: DHW heating operation starts
if water temperature and setting temperature
difference is larger than differential temperature.
DHW can be heated up using the heater,
the heat pump or a combination of both.
Only available when Hot Water Tank heater is
activated (DSW4 pin 3 ON).
Maximum setting temperature:
Maximum value of DHW setting
temperature permitted by the installer.
Maximum time:
Maximum time that DHW operation
can work using heat pump mode.
When the heat pump is stopped by
this function, DHW is still heated by
DHW heater when it is enabled, until
other conditions request stoppage.
• Range: OFF, 5 ~250 min
• Only in High Speed control and
Standard mode.
Space priority status:
If space priority function is enabled, Heat Pump
operation by DHW mode stops (and continue
with DHW heater, if necessary).
This function is only performed if space
heating or space cooling can be done. If it is
not possible, operation will continue in DHW
normally.
• Not available in High demand mode.
