code(3003) The input of system parameters should only be
carried out by trained personnel.
2.10 PC- Interface
The CONTROL 601/701 can be connected to a PC via a
serial interface. The solar thermal heating system can be
monitored and the settings made via the PC. „On-line Op-
eration“ allows records of temperature, yield and energy
to be made and for this information to be presented as
graphs and printed out. The data can be imported into an
MS-Excel database. Diagram 1 is a view of the PC-
software window.
„Off-line Operation“ allows the following data to be saved
and read out later:
Daily insolation
Daily maximum collector yield
Daily maximum collector temperature
Daily maximum upper thermal store temperature
Total insolation
The interface is installed by fitting the circuit board into the
module slot in the upper housing of the regulator. (see „In-
stallation“ on page 37 or page 58). The PC-Interface is
available as a package suitable for Window 95, 98 and
NT. For Windows version XP with USB connection a USB-
RS323 converter (e.g. Digitus DA-70119) is necessary.
3 Disruption and Function
Control
If a temperature sensor detects and reports a malfunction
(short circuit or interruption), the regulator will react ac-
cording to the relationships listed in the following tables.
Any disruption will cause the LCD indicator to flash and
the fault will be shown in the display panel. An interrup-
tion will be shown as:
Interruption in Sensor
N
o
. ...
And a short circuit as:
Short Circuit in Sensor
N
o
. ...
A disruption notice and a response to it will only occur for
a function which is activated. That is, if a function (e.g.
yield or frost protection) is not activated and no sensor is
connected, no disruption will be detected or notified, and
there will therefore be no response to a disruption in the
sensor.
