Program 1:
Instead of the two solar pumps, one pump and a three-way valve are used
(pump-valve system). The speed control (if activated) only operated when filling tank 1.
Without a priority allocation, tank 2 is filled by priority.
A1
... common pump
A4
... Valve (A4/S receives power when filling tank)
All pr2:
In program 0 the feed of tank
TK1
by pump
A3
is only controlled by differ-
ence
TK2 T6 – TK1 T2
. This program also includes the boiler temperature. When feeding
tank
TK1
by pump
A3
the difference boiler
T5 – TK1 T2
will be considered additionally (same
setting
diff3
). Both
min
thresholds are active.
A1 = T1 > (T3 + diff1) & T3 < max1
A2 = T5 > (T4 + diff2) & T4 < max2 & T5 > min1
A3 = T6 > (T2 + diff3) & T2 < max3 & T6 > min2
or T5 > (T2 + diff3) & T2 < max3 & T5 > min1
A4 = T1 > (T4 + diff4) & T4 < max4
All pr4:
If both tanks have reached their maximum temperature due to the solar
power system, solar pump
A1
and feed pump
A3
are switched on (
reverse cooling func-
tion
).
A3 ... or
T3 > max1 & T6 < T3
All pr8:
If both tanks have reached their maximum temperature due to the solar
power system, solar pump
A4
and feed pump
A2
are switched on (
reverse cooling func-
tion
).
A2 ... or
T4 > max2 & T5 < T4
Note:
If a solar pump is switched off manually, the controller works during
reverse cooling
as the tank limit would be reached.
Program 12:
The output
A2
becomes available, if the feed function of tank
TK2
is done by
the boiler controller. In this program
A2
only switches with the thermostat function
max2
at
T5
(e.g. burner requirement)
Program 13:
Function like program 12, but with pump–valve system at the solar sector (see
program 1)
Program 14:
Similar to Program 12. The burner requirement
A2
switches on at
min1
on
T5
.
Switch off appears when
T2
has exceeded the threshold
max2
.
Program 15:
Function like Program 14, but with pump–valve system in the solar system.
