◆ Electrical heater
Proportional band:
• Control to determine how fast
setting temperature is going
to be reached. Higher values
imply fast achievement of water
setting point and therefore higher
utilization of heater.
Reset factor:
• Used to guarantee setting
temperature achievement
without surpassing its value.
Higher values imply less utilization
of heater.
Waiting time:
• Delay time to start Electric
Heater in case all conditions
allow Electric Heater to start
after HP has been started. Only
in case of Backup option.
◆ Solar combination - Total control
ΔT connection:
• Allows to specify a difference
temperature between tank and
Panel temperature to allow solar
operation. Solar operation is
allowed in case Panel temperature
is "ΔT connection" ºC above tank
temperature.
ΔT disconnection:
• Allows to specify a difference
temperature between tank and
Panel temperature to stop solar
operation. Solar operation is not
allowed in case Panel temperature
is "ΔT connection"ºC below tank
temperature
Panel antifreeze temperature:
• Minimum Solar panel
temperature at which Solar
Pump is switched ON in order
to protect system against frost
formation at pipes due to low
ambient temperature.
PMEN0602 rev.0 - 05/2023
Operation:
• Starting: Space Heating electric Heater is switched
ON in case of low water temperature and low
ambient temperature to provide extra capacity to HP.
• Backup: Space Heating Electric Heater is switched ON
in case of low ambient temperature (below Bivalent
point) in order to provide extra capacity to HP at
coldest days of winter.
Bivalent point:
• Electric heater is enabled to operate in case ambient
temperature goes below this value. Only in case of
Backup option.
Supply setting offset:
• Setting offset for electric Heater. Higher values imply
earlier stoppage of electric heater and vice versa.
Only in case of Backup option.
Inter stage time:
• Time of Electric Heater phase overlapping when there
is switch ON/OFF transition from/to phase 1 to/from
phase 2. Only in case of Backup option.
DHW maximum time:
• Maximum time YUTAKI allows to heat tank
by means Solar. At the end of this time Solar
pump is stopped regardless temperature
conditions at Solar Panel.
DHW minimum time:
• Minimum Time solar operation cannot be
performed once it has been stopped due
to DHW Maximum Time or due to low
temperature at solar panel.
DHWT maximum storage temperature:
• Maximum DHW temperature that allows
Solar operation.
Panel minimum temperature:
• Minimum temperature of the solar Panel to
allow Solar operation
Panel overheat temperature:
• Maximum panel operation temperature at
which Solar Pump is set to off in case Panel
sensor reads a temperature above this value
in order to protect system.
• In case that the solar pump is stopped due
to panel overheat temperature, the YUTAKI
unit sets solar overheat output to high state
provided that this function has been setup
"1.8.2.10 Inputs, Outputs and
as described in
Sensors configuration"
