Installation and operating manual KT-Elektronik
1 Operation
The controller is factory-provided with standard temperature settings and timing
programs and therefore ready for use.
The current date and time have to be set at initial operation of the controller (Chapter
1.4).
1.1 Controls
The operational controls are located on the front side of the controller.
1.1.1 Rotary pushbutton
Rotary pushbutton
Turn :
Display, select settings and function blocks
Push :
confirm selection or setting

1.2 Display
During operation, the display shows the current time as well as information about the
status of the controller. The usage periods are represented by black squares below the
row of numbers. Symbols mark the operational status of the controller.

The following applies to the icon of the collector pump(s):
Icon or Description
Icon off Pump off
Icon flashes briefly Condition to turn on the pump is met but the
pump is still off because of the minimum idle
time.
Icon is on but disappears for a
short time in intervals
Condition to turn off the pump is met but the
pump is still running because of the minimum
running time.
Icon on Pump is running
The controller status can be viewed at operating mode level (Chapter 1.3 ).

1.3 Retrieving data – Information level
In the standard rotary switch position „Information level“ one can retrieve
informations about time, date, vacation-times and holidays as well as the temperature
set-points for the connected sensors and their current temperature.
Note: Information can also be retrieved in level "manual operating mode". To do so,
select "Info", then confirm and proceed as described.
Procedure:
Select value.
The screen now displays different items one after the other, depending on the
configuration of the controller.
__:__ Current time
Flow temperature from the collector to the storage tank CVF
Return flow temperature from the collector to the storage tank CVF
Temperature at storage tank sensor SF1
Temperature at storage tank sensor SF2
Temperature at solar collector CF1
2 Temperature at solar collector CF2
Operating hours of solar circuit
Set-point/threshold and actual value comparison.
When the time is marked in the display, pressing the rotary pushbutton will
show the date.
