Status display Status
The status display offers information in special system situations and when problems
occur. It is primarily intended for us with solar power systems but can also be useful with
other diagrams. The status display can, however, then only be set off due to an active
function check or defective sensors S1 to S6. In solar applications, there a three status
ranges:

Function check and collector excess temperature not active
= no system response is
analyzed. Only a bar appears in the display under
Status
.

Collector excess temperature is active
= the excess temperature that occurs at the
collector during system standstill only displays
CETOFF
(
c
ollector
e
xcess
t
emperature
cut
-off
active) under
Status
during this time. The display
Status
does not flash.

Function check is active
= monitoring for interruptions (
IR
) / short circuits (
SC
) of
sensors and circulation problems (if also activated). If the output is active and the
differential temperature between the sensors is greater than 60K for more than 30
minutes, the error message
CIRC.ER
(
cir
culation
err
or) is issued. The index in the lower
display line shows the output where a circulation error has occurred. The index in the
side display area indicates the output, at which the circulation error occurred.
 Legionella protection function is active = During the runtime
RT LEGION
is displayed
under
Status
.
 Drain-back function with low water protection is active = in the event of low water
Stat DB
ERR
is displayed and the solar pump switched off. A reset is only possible if the controller
is switched off and on.
Error messages remain displayed (and
Status
blinks) even after the error has
disappeared; they have to be deleted in the status menu via the command
CLEAR
.
OK
appears under
Status
if the monitoring functions are activated and the system is
running well. If anything special happens,
Status
blinks regardless of the display position.
You can only enter the status menu if there has been an error. Then,
ENTER
is displayed
instead of
OK
or
CETOFF
in
Status.
If one of the two control outputs is set to "
STAT N
" or "
STAT I
" and the function control is
activated, then if any of the errors "sensor open circuit, sensor short-circuit or circulation
error" occur, the control output is switched over. Subsequently an auxiliary relay can be used
to forward this error message to a signalling device. Upon collector excess temperature
switch-off
CETOFF
, the control output does not switchover.
