This function is activated if a fault is realized by the con-
troller. In that case the message relay is activated (e.g. for
pilot lamps)
Possible errors are:
• Sensor defect
• Real-time-clock defect
• Ram (EEPROM) defect
Please note that a message made by the plausibility control
does not activate a relay.
Message relay (Error report):
System warning „nocturnal circulation“:
This message is shown if the collector temperature bet-
ween 11 p.m. and 5.00 a.m. is higher than 40 °C or a store
is charged.
In order to avoid release of this message due to short-term
disturbences, the above-mentioned release condition must
be given for 1 minute.

The value temperature feed flow shows the current
flow temperature of the heating medium.
The value
outside temperature
shows the outside
temperature influenced by the weather.
Tflow:
Toutd.:
The measured outside temperature and the adjusted heating
curve result the set flow temperature. Onto this the correc-
tion value of remote control as well as the day correction
or night correction will be added.
Set flow temperature = heating curve tempe remo-
te c (day correction or night correction).
For the case that the set flow tempearature is higher than
the adjusted flow maximum temperature, the set flow tem-
perature is equate with the flow maximum temperature.
Flow Set:
Adjustment channel for the night correction of the heating
curcuit. For the night correction weekly timer 1 with its
21 time frames (see below) can be adjusted. The set flow
temperature will be dropped by the adjusted temperature
Night corr.:
Adjustment range: -20 ... +30 K
