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 1.5).
1.1 Controls
The operational controls are located on the front side of the controller.
1.1.1 Control Button and selector switch
Control button
Turn :
Display, select settings and function blocks
Push :
confirm selection or setting

The following applies to the icon of the collector pump:
Symbol 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
1.4 Retrieving data - Information level
In the standard rotary switch position „Information level“ one can retrieve
informations about time, date, as well as the temperature set-points for the connected
sensors and their current temperature.
Procedure:
Select value.
The screen now displays different items one after the other, depending on the
configuration of the controller.
__:__ Current time
Collector temperature CF
Temperature at storage sensor SF
Display the operating hours of solar circuit
Set-point/threshold and actual value comparison.
When the time is marked in the display, pressing the control button will show
the date.

Note: Information can also be retrieved in level "manual operating mode". To do so,
select "Info", then confirm and proceed as described.
SOL3-1
1.5 Setting the system time
System time and date have to be set during first start-up and after each loss of power
with a duration of more than 24 hours. This is indicated by a blinking time display.
Procedure:
Turn rotary switch to the position
“system time” (right hand).
Display: shows current time setting
Change the time setting.
Confirm the time set.
Display: shows current year setting
Change the year setting.
Confirm the year set.
Display: show current date setting (day.month)
Change date setting.
Confirm the date set.
Display: shows current time setting
Move the rotary switch back to the "Information
level" position (left hand).
