PC-ARFH1E1(02/03) FUNCTIONALITIES

System optional functions
Smart function:
To block or limit the heat pump or increase
demand due to electricity availability. See
detailed information below.
Energy configuration
Capacity configuration:
Due to usage of water temperature inlet and outlet
+ water flow level, an estimation of capacity can
be checked through the Operation information -
Energy data menu.
Smart Function
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..

Hydraulic separator status:
Enable if there is a Hydraulic separator or a
buffer tank installed. Check that WP3 is set
in output 2 (see section
Outputs and Sensors configuration")
Energy configuration:
Setup of power consumption readings. See
detailed information below.
Status:
Enable or disable energy configuration options
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 disabled the YUTAKI
software does an estimate consumption of
the system.
• In case of using power meter 1 or 2 input
must be configured at the Inputs menu
"1.8.2.10 Inputs, Outputs and
(see section
Sensors configuration")
Smart Action:
Check that Smart Act/SG1 is set in input 5 (see
"1.8.2.10 Inputs, Outputs and Sensors
section
configuration")
• 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
Service Manual for detailed information. It is
necessary to configure 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:
Configure the ampere consumption limitation.
Only visible when smart action is set as HP
Limited (A).
