"Rcoo" parameter (default value "On").
When the temperature of the water in the tank exceeds
the level set in "Maxtemp tank1" and the temperature of
the collector has gone down by 10°C, the pump starts-
up to cool down the tank via the collectors. The pump
will switch off when the temperature of the water drops
below the level set in "tkM1" or when the difference
between the temperature of the collector array and of
the tank is below 2°C.
3.7 ANTIFREEZE PROTECTION.
"FrEZ" parameter (default value "off ")
This option maintains the temperature of solar panel
T1 or T4 above the level set for freezing with the "FrEt"
parameter, activating pump P1 or P2.
This option can be used to reduce the build-up of snow
on the panel and to increase the efficiency during the
day or prevent damage to the solar liquid.
N.B.: it is preferable not to use this function in very cold
places to prevent using too much energy accumulated
in the tank.
- To activate the function, press (
- Now you can adjust the Freezing setting.
"FrEt" parameter (factory value "3°C" (Adjustable from
-20°C to + 7°C with factory value 3°C).
3.8 PRIORITY TANK.
"Prtk" parameter (default value "1").
Available only with system with two tanks (2 and 3).
On this menu you can choose a primary tank for the
loading priority.
3 possibilities:
"0" - No priority is done on the tanks. The two tanks are
loaded independently; the only condition is that the
"dt" value is sufficient to authorize the loading.
"1" - The primary tank will be the tank 1 managed by the
sensor T2. It will be named with a small number
"1" in the tank on the main screen.
"2" - The primary tank will be the tank 2 managed by the
sensor T3. It will be named with a small number
"2" in the tank on the main screen.

If a primary tank is chosen, the loading of this tank will
be made by priority, the secondary tank will be only
loaded if:
- The primary tank reaches the value "TkM1 or TkM2"
adjusted on "setting" menu.
- If the collector temperature is too small to authorise the
loading of the primary tank. In this case the secondary
tank will be loaded with the cycle function defined by
the two following parameters. This function allows to
switch back from second tank to the priority tank.
(1 cycle = "Prio tank load" ("priority time loading") +
"Prio tank break" ("priority time interruption. " )).
N.B.: If the value "TkM1 or TkM2" of the primary tank
is sufficient, loading will switch to the latter.
3.9 PRIORITY TIME BREAK.
"Prtb" parameter (default value "2 min").
It's the interruption time (OFF time) for the cycle
function.
- To change the duration press (
or decrease the time. (Adjustable from 1 to 30 min with
factory value 2 min).
3.10 PRIORITY TIME LOAD.
"Prtl" parameter (default value "15 min").
This is the load time duration (ON time) for the cycle
function.
- To change the duration press (
or decrease the time. (Adjustable from 1 to 30 min with
factory value 15 min).
