Plausibility indices
The internal plausibility check ascertains whether conflicting settings have been detected in the controller.
In this event, an information window displays an error code. The reasons which cause the information
window to appear, along with each corresponding error code, are described in the following table. Check
your settings at the controller, and correct them if necessary.
P 1
Maximum temperature storage tank 1 + switch-on temperature difference 1
> maximum collector temperature
P 5
Temperature differential control storage tank 1 < switch-off temperature difference 1
P 6
Temperature differential control storage tank 1 < switch-off temperature difference
(system with collector arrays)
P 8
Temperature differential control storage tank 3 < switch-off temperature difference 3
P 9
Temperature differential control storage tank 1 + 5 K < switch-off temperature differ-
ence 1 (system with external heat exchanger)
P 10
Temperature differential control storage tank 1 + 5 K < switch-off temperature differ-
ence (system with collector arrays and external heat exchanger)
P 1
Target temperature control storage tank 1 < minimum collector temperature
P 13
Target temperature control storage tank 1 > maximum collector temperature
P 18
Target temperature control storage tank 1 + 5 K < minimum collector temperature
(system with external heat exchanger)
P 19
Target temperature control storage tank 1 + 5 K > maximum collector temperature
(system with external heat exchanger)
P
Target temperature control storage tank 1 < minimum temperature loading circuit 1
P 3
Target temperature control storage tank 1 > maximum temperature loading circuit 1
P 8
Switch-on temperature difference external heat exchanger + maximum temperature
storage tank 1 > maximum temperature loading circuit 1
P 9
Switch-on temperature difference external heat exchanger + maximum temperature stor-
age tank > maximum temperature loading circuit 1
P 31
Temperature differential control storage tank 1 < switch-off temperature difference
external heat exchanger
