B.3 Controller Description
TRS6 K Controller permits control of up to 2 heating circuits (one mixed, one unmixed), control of DHW heating and control of
automatic operation of solar thermal systems, solid-fuel boilers and auxiliary electric / gas-fired heat sources. It involves two PWM
outputs for high-efficiency pump control, 3 relay outputs and 6 inputs for temperature sensors. It can be connected to CAN bus
and used for example together with Caleon Room Unit.
The Controller can be used with different variants of installations, see Hydraulic Variants in Chapter D.2.
Important characteristics of the TRS6 K are:
•depiction of graphics and texts on a backlit display
•simple viewing of the current measurement values
•statistics and system monitoring by means of statistical graphics
•extensive setting menus with explanations
•menu block can be activated to prevent unintentional setting changes
•resetting to previously selected values or factory settings
B.4 Disposal
IMPORTANT INFORMATION ON PROPER DISPOSAL OF E-WASTE AS
REQUIRED BY THE EC DIRECTIVE 2002/96/EC (WEEE)
Do not dispose of this product as unsorted municipal waste. Please dispose of this product by returning it to the point of sale or to
your local municipal collection point for recycling.
Respecting these rules will help to preserve, protect and improve the quality of the environment, protect human health and utilize
natural resources prudently and rationally.
The crossed out wheeled bin with marking bar, printed ether in the Manual or on the product itself, identifies that the product must
be disposed of at a recycling collection site.

Installation
C.1 Wall Installation
Install the Controller in dry rooms only!
1. Unscrew cover screw completely.
2. Carefully pull upper part of housing from lower part.
3. Set upper part of housing aside. Do not touch the
electronics inside.
4. Hold the lower part of the housing up to the selected
position and mark the three mounting holes. Make sure
that the wall surface is as even as possible so that the
housing does not become distorted when screwed on.
5. Using a drill and size 6 bit, drill three holes at the points
marked on the wall and push in the plugs.
6. Insert the upper screw and screw it in slightly.
7. Fit the upper part of the housing and insert the other two
screws.
8. Align the housing and tighten the three screws.
C.2 Electrical Wiring
Before working on the unit, switch off the power supply and secure it against being switched on again! Check that there is
no power flowing! Electrical connections may only be made by a specialist and in compliance with the applicable
regulations. The unit may not be put into operation if there is visible damage to the housing, e.g. cracks.
Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed
temperature sensor cables only into the left-hand side of the unit, and mains voltage cables only into the right-hand side.
The Controller is not equipped with a power switch. It can be switched off e.g. by a circuit breaker in the electrical enclosure.
The cables being connected to the unit must not be stripped by more than 55 mm, and the cable jacket must reach into
the housing just to the other side of the strain relief.
1. Open the Controller cover.
2. Strip lines a max. of 55 mm, assemble the strain reliefs.
3. Strip ends of all wires 8-9 mm.
4. Open clamps with a fitting screwdriver and connect the conductors following the wiring diagram.
5. Close the cover again and fix with the screw.
6. Turn on mains supply and commission the controller.

9
C.3 Installing the Temperature Sensors
The controller operates with Pt1000 temperature sensors.
The max. length of a sensor cable is 10m, use cables of 0.75 mm2 cross section min. Ensure there is no contact resistance!
Position the sensor precisely in the area to be measured! Only use immersion, pipe-mounted sensors with the appropriate
permissible temperature range. Flat-mounted contact sensors shall be used only exceptionally.
Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed
temperature sensor cables only into the left-hand side of the unit, and mains voltage cables only into the right-hand side.
When connecting high-efficiency pumps via PWM, it is necessary to respect the proper wiring (i.e. connect “PWM output”
terminals on the Controller to “PWM input” terminals on the Controller and “GND” on the Controller with “GND” on the pump).

E.2 Commissioning Help - Setup Wizard
The first time the controller is turned on, a request appears on the display
regarding setting the language and time.
After that a query appears as to whether you want to parameterize the
controller using the commissioning help or not. The commissioning help
can also be terminated or called up again at any time in the special
functions menu. The commissioning help guides you through the
necessary basic settings in the correct order, and provides brief
descriptions of each parameter in the display.
Pressing the “esc” key takes you back to the previous level so you
can look at the selected setting again or adjust it if desired.
Pressing the “esc“ more than once takes you back step by step to
the selection mode, thus cancelling the commissioning help. Finally, the mode
menu 4.1 “Manual” should be used to test the switched outputs with the consumers connected, and to check the
sensor values for plausibility. Only after checking proper operation of all connected consumers and sensors in the
Manual mode, switch on automatic mode.

17
E.3 Free Commissioning
If you decide not to use the commissioning help, you should do the necessary
settings in the following sequence:
•menu 10. Language
•menu 3.1. Time and Date
•menu 7.1. Program Selection
•menu 5. Settings, all values.
•menu 6. Protection Functions (if any adjustments necessary)
•menu 7. Special Functions (if any adjustments necessary)
Note: The setup wizard can be accessed in menu 7.12 at any time.
Finally, the mode menu 4.1 “Manual” should be used to test the switched outputs with the consumers connected, and
to check the sensor values for plausibility. Only after checking proper operation of all connected consumers and
sensors in the Manual mode, switch on automatic mode.
Consider the explanations for the individual parameters on the following pages and check if further settings are necessary
for your application.

Measurement Values
1. Measurement Values
Menu 1. Measurement Values is intended to display the current measured
temperatures. The selected program and the specific model design determine
which measurement values are displayed.
The menu is closed by pressing “esc” or selecting “Exit measurements”.
If “error” appears on the display instead of the measurement value, there
may be a defective or incorrect temperature sensor. If the cables are too
long or the sensors are not placed well, small deviations in the
measurement values may occur. In this case, the display values can be
compensated by adjustments in the controller - see “Sensor calibration”,
chap. 7.6. The selected program, connected sensors and the settings
determine which measurement values are displayed.

19
Statistics
2. Statistics
Menu 2. Statistics is intended for function control and long-term monitoring of
the system.
The menu is closed by pressing “esc” or selecting “Exit statistics”.
For system data statistics it is essential for the time to be set accurately
on the controller. Please note that the clock will stop if the mains voltage
is interrupted, and afterward must be reset. Incorrect time may result in
data being cleared, recorded incorrectly or overwritten.
2.1. Today
In the graphical overview the characteristics of the flow temperature for the present day is shown from 0 to 24 h. The right button
changes the unit of time (days) and the two left buttons scroll through the diagram.
