7.3.7
Programme “Automatic”
P.5
Basic
The device operates in the programme “Automatic”
P.5
and heats the water with the device’s
generator up to the set temperature. It operates inside the limited temp. zone of the evaporator.
In case the temp. of the evaporator is too low, the device automatically switches to heating
with the electric heater.
Advanced
The water is heated with the device’s generator and automatic switch to the electric heater in
case of low evaporator temperature. The device operates fully automatically with the priority
of the device’s generator operation until the set water temperature is reached. If the
temperature of the evaporator is outside the operation zone, the device automatically switches
to heating with the electric heater. In case the temperature of the evaporator drops below the
temperature set by the parameter (L.1), the electric heater turns on. Shut-down of electric
heater occurs 30 minutes after the temperature of the evaporator is raised by 3 °C.
7.3.8
Programme “Photovoltaic-PV”
P.6
Basic
This programme heats the water in combination with photovoltaic panels and performs the
same as the “Automatic”
P.5
programme, but in the case of an active external signal from the
inverter of the photovoltaic power plant, the device raises the water temperature in the buffer
tank for DHW for the value set with the parameter
L.6
.
7.3.9
Programme “External signal”
P.7
Basic
The operation of the device is the same as programme “Automatic”
P.5
. In case of an inactive
external signal, the device is in stand-by. In case of an active external signal, the device will
heat the water up to the temperature set in the programme P.7. The temperature of heated
water can be set to a value different from the ones in programmes “Normal”, “Res. source”,
and “Automatic” and “Photovoltaic-PV”. Remote activation of the device operates only in the
presence of an external signal.
7.3.10 Parallel operation of the device’s generator and electric heater (only automatic
programmes P.5, P.6 and P.7):
Choose parameter L.1. Use key
or
to adjust the desired temperature for parallel
activation of the electric heater.
Approximate values for setting the parameter L.1 are given in the table.

NOTE
Water overheating in the programme “Res. Source”
P.3
is performed with an
electrical heater. The temperature of the evaporator does not influence the
operation.
