SOLAR SYSTEM.
In this section it will be possible to set the values to
manage the solar pump. This menu will be enabled only
if "1" or "2" has been set under "Pump no. " in the "System
definition" menu.
It is possible to install a second solar pump only if:
- there is only one heat pump;
- system decoupling disabled;
- system probe not installed.
Press the arrows
Press the
button to enter the submenu (W01).
- ∆T activation (W01) (1÷20°K default 6°K);
- ∆T deactivation (W01) (0.5÷19.5°K default 4°K);
The values reported above indicate the temperature dif-
ference between solar panel and storage tank. When this
value is reached the solar circuit pump is either activated
(started up) or deactivated (stopped).
N.B.: The screen for solar pump 2 is displayed even if
only one solar pump has been configured.
- Maximum T (W03). Once this value has been exceed-
ed the solar circuit pump stops working;
- Enable (Yes / No) (W04). The storage tank brings the
maximum limit to 90°C and once the temperature of
the manifold is lower than the one read on the storage
tank, the pump is re-activated to cool the storage tank
down until it reaches the maximum temperature;
- Limit t. (W05) Once this value has been exceeded the
solar circuit pump stops working;
- Enable: (Yes / No) (W06). This forces the solar pump
to exceed the set max T. even if the set max T. for the
domestic hot water is reached (it avoids stagnating);
- Max t. (W07) The solar circuit pump starts working
again to cool the solar collector when this value is
exceeded. The pump switches off if the temperature
of the manifold decreases or if the temperature of the
storage tank reaches 90°C. In any case, the limit set in
the "W05" screen.
and select "08. Solar system".
N.B.: As soon as the temperature of the manifold falls
below the set setpoint this function is disabled. The
storage tank's cooling system is also enabled when the
temperature of the solar collector falls 5°C below that of
the storage tank.
- Enable (W07): (Yes / No);
- Min T. (W07): (10÷90°C) the solar circuit pump is
enabled to start operating only if the temperature set
on the manifold is reached.
- Enable (Yes / No) (W08). This allows the pump to be
enabled to start heating the solar collector in case of
very low temperatures.
- Min.t. (-10÷10°C) (W08). The solar circuit pump is
enabled to start working if the external temperature
falls below this value.
- Enable (Yes / No) (W09). This allows the probe lo-
cated on the solar circuit return to start working; The
measured value will only be displayed.
