5.5.2
AUTO Mode
In the
AUTO
mode, the unit works as a heat pump with the support of the heating element, and the operation
of the heating element is optimised in order to maintain the COP of the appliance.
The heating element starts whenever:
•
is enabled by the user manually (by pressing
E-HEATER
).
•
LP contact opens (low ambient temperature, lack of coolant, leak in the cooling circuit, etc.).
•
compressor running time exceeds the T05 parameter*
•
water temperature is below P08*
* The parameter is adjustable (
ON/OFF
)
5.5.3
Boost Mode
In the
BOOST
mode, the unit works as a heat pump with the support of the heating element, and the run
of the heating element isn't optimised. This mode allows users to achieve sufficiently hot water in a shorter
period of time.
5.5.4
TCC Mode
The TCC function
provides the ability to achieve higher water temperatures at a time when an alternative
source of electric energy (photovoltaic system, etc.) is available.
You just need to connect the control connector
between the photovoltaic inverter and the appliance's
control panel. This connection to the panel must be
made potential
-
free (no voltage). The voltage on this
contact causes irreversible damage to the appliance.
If the contact is K1, it activates the TCC function, and
all sources of heat (both the heat pump and the
heating element) work according to the new
programmed operating parameters.
Note:
When the contact K1 is opened, the device
operates according to the preset operating mode (Eco,
Auto or Boost) and the corresponding parameters.
Contact
K1 can be thus used for the tariff control, i.e.
to switch according to the "night current". For this
purpose, connect potential
-
free either the timer or
the contact controlled according to the HDO signal.
