4.10.2 Cooling function.
Available only if extra function "2" is selected in sub-
menu Extra.
Cooling start:
"EXSt" parameter (default value "75°C").
- Setting level to start cooling the tank 1 (by activating
P3 output) to another heat storage unit, for example
when the water temperature in (T3) is above this setting
level. (Adjustable from +20 to 90°C with factory value
75°C).
Cooling hysteresis:
"EXHY" parameter (default value "10°C")
- - Value of the hysteresis to stop cooling the tank 1 when
the water temperature in (T3) is under Cooling start
temperature minus hysteresis value. (Adjustable from
+2 to 30°C with factory value 10°C).
4.10.3 Diff. control function.
Available only if extra function "3" is selected in submenu
Extra (only available with system 1).
Max cold tank:
"EXMc" parameter (default value "65°C").
- Maximum level on tank 1 to stop the exchange func-
tion (T3 = EXMc). (Adjustable from +15 to 95°C with
factory value 65°C).
Min warm tank:
"EXmW" parameter (default value "15°C").
- Minimum level on external tank to start the exchange
function (T4 = EXmW). (Adjustable from +0 to 95°C
with factory value 15°C).
dTMax:
"EXdM" parameter (default value "15°C").
- Value of the difference between storage units to start
the exchange function. (Adjustable from +3 to 40°C
with factory value 15°C).
dTMin:
"EXdm" parameter (default value "7°C").
- Value of the difference between storage units to stop
the exchange function. (Adjustable from +2 to 30°C
with factory value 7°C).
4.10.4 Antistagnation function.
Available only if extra function "4" is selected in sub-
menu Extra.
Start level:
"EXSt parameter (default value "110°C").
- Setting level on collector (T1) to start the function,
the pump P1 will be turned on to discharge the warm
temperature of the collector through the outputs P1 &
P3. (Adjustable from +0 to 200°C with factory value
110°C).
Stop level:
"EXOF" parameter (default value "90°C").
- Setting level on collector (T1) to stop the antistagna-
tion function, the outputs P1 & P3 will be turned off.
(Adjustable from +0 to 150°C with factory value 90°C).
P1 working time:
"P1Wt" The operating hours counter of the solar pump
P1. (Solar loading).
- The counter can be reset ("0"). To do so, press the key
▶
( +) a few seconds until the counter resets to zero.
