Pump speed is controlled according to collector tempera-
ture rather than (usual) temperature difference. The aim
is to maintain constant collector temperature, adjustable
with parameter “Tcolset“.
Target temperature:
Solar/Options/Target tem.
selection „Yes“, „No“
factory setting: „No“
if you select „Yes“.
Solar/adj. values/tcolset
adjustment range: 20 … 110 °C
factory setting: 65 °C
Parallel relay:
Solar/Options/Par. Relay
selection: „Yes“, „No“
factory setting: „No“
If the solar circuit pump is switched-on, this relay is acti-
vated in parallel.
In 2-collector systems which are working with 2 pumps, the
parallel relay is activated if one of the 2 pumps is activated.
CS-Bypass:
Solar/Options/CS-Bypass
selection: „Yes“, „No“
factory: setting „No“
if you select „Yes“:
Solar/adj. values/CS-Byp.
adjustment range: 100 ... 500 W/m
2
factory setting: 200 W/m

If the irradiation exceeds the adjusted value CS-bypass, the
collector circuit is operated. It is switched off when the
irradiation has fallen below the value „CS-bypass“ for at
least 2 minutes.
The collector circuit is operated with minimum pump
speed.
2-collector systems:
If a loading of the store is carried out in these systems, the
function is switched-off.
Collector emergency shutdown:
Solar/adj. values/Tcolsec
adjustment range: 110 … 200 °C
factory setting: 130 °C
hysteresis: 10 K
At high collector temperatures (depending on system pres-
sure or antifreeze concentration etc.) the systems stag-
nates. This means that solar loading is not possible.
If the adjusted temperature threshold „Tcolsec“ is exceed-
ed, the corresponding collector will no longer be used for
loading.
Afterheating suppression:
Solar/Options/ah suppress.
selection: „Yes“, „No“
factory setting: „No“
if you select „Yes“:
Solar/Expert/ah suppress.
adjustment range: St 1 … St 4
factory setting: St 1
This function is active if a previously selected solar store
(parameter designation: “AH suppress.“ in the menu solar
expert) is being loaded.
Solar loading means that store loading is only carried out
for energy supply and not for cooling purposes etc.
Frost protection:
Solar/Options/Frost prot.
selection: “Yes“, “No“
factory setting: „No“
As soon as the temperature at the collector is 4 °C, the
frost protection function operates the loading circuit be-
tween the collector and the 1
st
store in order to protect
the medium in the loading circuit against freezing or co-
agulation.
If the collector temperature exceeds 5 °C, this function is
switched-off.
If the 1
st
store in the system is blocked, this function is
switched off or suppressed.
The pump output uses maximum pump speed.
2-collector system: In these systems, the circuit which fullls the switch-on
condition described above is operated.
