Prioritise charging of: External heat
source/X-volume
This is where you indicate whether the tank for the
external heat source or the X-volume (acc. tank) should
be prioritised when charging (shown only if alternate
charging has been defined).
Flow l/min 6.0 (0.1 to 50.0)
The flow circulating through the solar collectors should
be indicated here. (This can be read from the flow
meter in the system unit.) The flow must be read when
the solar panel pump is running at 100%. NB: The
flow is used as the basis for calculating the power and
cumulative energy. Incorrect flows will therefore produce
incorrect values for these parameters. The pump can
be set manually to 100% flow in the menu: Installer/
Service/Function test to take a reading.
11.13.2 Panel protection functions
This is where you set the functions that protect the solar
panels from over temperatures and the risk of freezing.
Over temp protection panel No (Yes/No)
The protection function is activated here to protect the
solar panel against over temperatures. This is done by
cooling the solar panel.
-max panel temp. °C 120 (100 to 150)
The maximum temperature that the panel may reach is
indicated here; the cooling function starts once it has
been reached. When cooling is active, heat is dumped
1) in the bore hole if there is bore hole recharging and
2) then in the tanks up to their maximum permitted
temperature.
When the temperature in the solar panel goes above
120ºC, the circulation pump will start and the text
“cooling panel” will be displayed in operation data.
When the temperature in the solar panel drops, but
remains high in the tank: The circulation pump will
continue to run and the text “cooling tank” will be
displayed in operating data. This will continue until the
tank has reached 60ºC.
(Charge temperature, factory setting.)
Cool over temp in tank No (No/Yes)
If energy has been transferred to the tank in order
to cool the panel, the function to cool the tank by
conveying energy to the panel is activated here. This is
to enable the system to receive panel cooling (e.g. on
the next day).
Over temp protection panel No
-Max panel temp °C 120
Cool over temp in tank No
-Tank cooled down to °C 50
Antifreeze protection panel No
-Activ when panel temp °C -25
Prioritize protection EHS-tank
Panel protection
-tank cools down to °C 70 (50 to 80)
This specifies the temperature that the tank is to be
cooled to once it has reached over temperature.
When this happens, “extra cooling” will be displayed in
operating data.
Antifreeze protection panel No (No/Yes)
In the winter, at extremely cold outdoor temperatures
there is a risk of the panels freezing (despite antifreeze
fluid). The function to take heat from the tank to the
panel is activated here.
