Energy conguration
Input calculation:
Enable or disable energy conguration options.
Capacity conguration:
Due to usage of water temperature
inlet and outlet + water ow level, an
estimation of capacity can be checked
through the Operation information -
Energy data menu.
Due to the estimation, values may differ
from real ones.
Power meter 1 or 2:
The power meter does a real measuring of the
power consumption.
If the power meter is enabled, it is possible
to see the information collected through the
Operation information - Energy data menu.
If “power meter” is Deactivated the YUTAKI
software does an estimate consumption of the
system.
In case of using power meter 1 or 2 input
must be congured at the Inputs menu (see
section “9.13.4.10 Inputs, Outputs and Sensors
conguration”).
Smart Function
1 / 3
2 / 3
3 / 3
Status:
Enable or disable smart function.
Trigger type:
Closed: Action when input is
closed
Open: Action when input is open
Start boiler:
Permission to use the boiler in case
that the system has been blocked
due to HP Block.
Start DHW Heater:
Permission to use the DHW heater
in case that the system has been
blocked due to HP Block.
Smart Action:
Check that Smart Act/SG1 is set in input 5 (see section
“9.13.4.10 Inputs, Outputs and Sensors conguration”).
HP Block: Heat Pump is forbidden in any
condition (Space Heating, Cooling, DHW) when
signal is active.
HP Limited (A): Limitation of power consumption
up to a limit of “x” amperes (to be set up in
Limitation of amperage).
SG Ready: The SG Grid is awarded to heat
pump series. This control technology integrates
the system in a smart grid by using two digital
inputs establishing an unidirectional connection.
See Service Manual for detailed information. It is
necessary to congure an input for SG2.
DHW Block: DHW Operation is forbidden when
signal is active.
DHW only: Heat pump operation for any
condition except DHW is forbidden when signal is
active. DHW operation is allowed normally.
Limitation by ampere:
Congure the ampere consumption limitation.
Only visible when smart action is set as HP
Limited (A).
SG Heating offset:
To adjust Space Heating setting temperature
increase when SG ready is in Low price mode.
SG DHW offset:
To adjust DHW setting temperature increase
when SG ready is in Low price mode.
SG Cooling offset:
To adjust Space Cooling setting
temperature decrease when SG
ready is in Low price mode.
