5.8 Connecting the TR- CONTROL (RE440)
The TR- CONTROL is a remote control unit with an inte-
grated thermostat. Each of the CONTROL 701 heating cir-
cuits can be controlled by a TR-CONTROL.
ADVICE:
The connection procedures and functions are described
in detail in the Technical Documentation for the TR-
CONTROL.
5.9 Connecting the Insolation Sensor (RE352)
For measurement purposes an insolation sensor can be
connected to the CONTROL 701. The clamp layout is
shown in diagram 3 below.
ES 24V GND

ADVICE:
The insolation sensor functions are described in para-
graph 2.3.6, page 9.
5.10 Installing a PC Interface (RE030)
The CONTROL 701 can be connected to a PC using a se-
rial interface. This can be used to monitor the solar thermal
and heating system. In addition, different temperature and
results values can be redorded and presented as graphs.
The interface is available as an accessory and can be con-
nected to the regulator at a later date. Before installing the
interface, first disconnect the mains supply from the regula-
tor and remove the regulator casing lid.
By loosening the screws (1) the plastic lid can be lifted up-
wards. The circuit board can be inserted into the module
slot in the upper part of the casing of the regulator. The
accompanying connection cable with a RS 232 plug is
connected to clamps A, B, C, and D of the „module1“
clamp row.

ADVICE
The programme functions are described in the online
help for the PC software.
5.11 Commissioning
When the instrument is connected to the mains electricity
supply, the chosen temperatures will be shown in the dis-
play panel. Using the Manual Operation point in the Serv-
ice Menu, set each output to ON (dependant on the oper-
ating system variation), to test that the connected outputs
are working without problem. The green control lamps
must light up and the pumps, valves and the mixer must
run.
After running the test set the swiitches to AUTO.
ATTENTION:
Manual operation must only be used for short periods
and only for system testing purposes. Continual switch-
ing on and off will lead to damage to the system or its
components, because the safety functions are overrid-
den.
