Diff. Control Function; Antistagnation Function - Immergas SOL 750 V2 Instructions For Installation And Use Manual

Cooling hysteresis:
"EXHY" parameter (Default value "10°C")
- Value of the hysteresis to stop cooling the tank1
when the water temperature (T3) is under
Cooling start temperature minus hysteresis
value. (Adjustable 1 to 30°C with factory value
10°C).

4.10.3 Diff. control Function.

Available only if extra function "3" is selected
on submenu Extra (only aviable with system 1).
Max cold tank:
"EXMc" parameter (Default value "65°C").
- Maximum level on tank1 to stop the exchange
function (T3 = EXMc). (Adjustable 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
0 to 95°C with factory value 15°C).
dTMax:
Parametro "EXdM" (valore di default "15°C").
- Value of the difference between storages to start
the exchange function. (Adjustable 3 to 40°C
with factory value 15°C).
dTMin:
"EXdm" parameter (Default value "7°C").
- Value of the difference between storages to stop
the exchange function. (Adjustable 2 to 30°C
with factory value 7°C).

4.10.4 Antistagnation Function.

Available only if extra function "4" is selected
on submenu Extra.
Start level:
"EXSt" parameter (Default value "110°C").
- Setting level on collector (T1) to start the
function, the pump P1 will be turnned on to
discharge the warm temperature of the collec-
tor trough the output(s) P1 & P3. (Adjustable
0 to 200°C with factory value 110°C).
Stop lever:
"EXOF" parameter (Default value "90°C").
- Setting level on collector (T1) to stop the
antistagnation function, the output(s) P1 &
P3 will be turnned off. (Adjustable 0 to 150°C
with factory value 90°C).
P1 working time:
"P1Wt" The operations hours counter accumu-
lates the solar pump P1. (Solar loading).
- You will have the possibility to reset the counter
("0"), for this press and maintain (
seconds. Then the counter will be reseted.
