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
1.5).
1.1 Controls
The operational controls are located on the front side of the controller.
The user is guided by means of rotary switches and pressing the control button described
below control levels.

1.2 Operating
The operation of the device SOL3-7follows a continuous uniform display and operating
philosophy.
Values and display texts are shown in black characters with no background. Elements for
direct input or selection are shown with white characters on black background. Choice
elements in rows oriented menus are shown with black characters on a gray background.
With the help of the rotary switch, a control level is set. The rotary pushbutton is used to
select and adjust.
1.3 Display
The contro er SOL3-7 it equipped with a graphica disp ay. The disp ay a ows it to
visua ize the current system scheme with a re evant sensor informations as we as state
informations of pumps and va ves for a quick overview of the operating condition of the
system.
Example of display in the information level:
For the use of the device the user is facilitated in operating levels for display and input of
operating parameters with clear text menus and explanatory texts.
Example of display in the setting level:
Example of display for checking and modifying of times-of-use (weekly schedule):

1.3.1 System scheme
With the on the display shown system scheme, the relevant sensor information, the
operating mode of the control circuits and state information of pumps and valves for a
quick overview of the operating condition can be visualized.
Among the symbols used in the system scheme are the following:
Element Symbol Meaning
Pump Pump is in operation
Pump is not in operation
Switching
valve Switching valve is showen with filled triangles
Valve
Valve is not in operation
Valve 'CLOSE' is in operation
Valve 'OPEN' is in operation
Auxilary
heating
Auxilary heating is not in operation
Auxilary heating is in operation
Collector
pump
A temporarily shown sun above a collector represents an
operating state indication of the pump belonging to the
collector.
Condition for the activation of the pump is not met and the
pump is not operating.
Condition for the activation of the pump is met and the pump
is operating.
The condition for switching off the pump is met, but pump is
due to the minimum ON time still in operation.
Condition for switching on the pump is met, but pump is due
to the minimum OFF time yet in operation.

1.3.2 Operating Mode
The operation of the heating circuit, hot water circulation and auxilary heating can be
affected depending on time and day of week. There are two different set-points for night
and day exist. A usage schedule determines when to operate in day-time operating mode
or night-time operating mode. It is possible to deactivate schedules (without deleting them)
and to specify manually to operate permanently in day-time or night-time operating mode.
Icons on the display indicate the current operating mode for each function of the controller:
Daytime operating mode (nominal operation)
Values are permanently adjusted to meet the set-points entered for nominal operating
mode regardless of scheduled time ranges or summer operating mode settings.
Night-time operating mode (reduced operation)
Values are permanently adjusted to meet the set-points entered for reduced operation
regardless of scheduled time ranges.
Normal operating mode off
Normal operating mode is deactivated regardless of the scheduled time ranges. Only
equipment anti-freeze is ensured (if activated).
Automatic operating mode
The controller automatically switches between both modes depending on the time.
Manual operating mode
Manual control of valves and pumps (Chapter 3).
The operating modes of heating circuit, hot water
circulation and auxilary heating are in the system scheme,
context-sensitive arranged and allow capture at a glance
the current function of the system part.
Operating mode Symbol Symbol Time phase
Standby Nominal operation
