A 2 - About the controller
The weather controlled Heating Controller TRS 3 facilitates efcient use and function control of your heating
system. This type is designed to control one mixed heating circuit. It is equipped with 3 outputs for e.g. one
pump and one mixing valve. The TRS3 has 3 inputs for heat sensors and a remote controller. For each step in
the input process the individual entry keys are assigned to appropriate functions and explained. The controller
menu contains headwords for the measured values and settings, as well as help texts or clearly-structured
graphics.
- both graphics and texts on a backlit display
- simple viewing of the current measurement values
- analysis and monitoring of the system also by means of statistical graphics
- extensive menus with interactive explanations
- menu lock can be activated to prevent unintentional setting changes
- usual preset parameters in factory setting

C - INSTALLATION AND WIRING
C 1 - Wall installation
Install the controller in dry areas only.
Installation instructions:
1. Unscrew cover screw completely.
2. Carefully pull upper part of housing from lower part.
3. Set upper part of housing aside, being sure not to
touch the electronics when doing so.
4. Hold the lower part of the housing up to the
selected position and mark the 3 mounting holes.
Make sure that the wall surface is as even as possible
so that the housing does not become distorted when it
is screwed on.
5. Using a drill and size 6 bit, drill 3 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 - Electric wiring
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 mains switch. For this purpose please use e.g. a circuit
breaker. 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.
Wiring instructions:
1. Make sure the circuit breaker is in off position and
power supply is off.
2. Open the controller.
3. Strip the cable by 55 mm max., insert and t the
cable strain relief. Strip the last 8-9 mm of all the wires
(C.2.1).
4. Press the terminals e.g. with a screwdriver (Fig.
C.2.1.d) and wire the cables following the diagrams in
Part B (Page 5).
5. Lock the housing lid onto the top margin of its
bottom counterpart, push the cables inside and close
the housing gently.
6. Secure with a screw.
7. Switch on mains voltage and place controller in
operation.

C 3 - Installing the temperature sensors
The controller operates with Pt1000 temperature sensors.
Max. sensor lead length is 30 m and its cross section at least 0.75 mm2.
Make sure that there is no contact resistance! Use immersion or pipe-mounted sensors. The
temperature sensor cables must be routed separately from mains voltage cables!

D.2. RC 21 Remote Controller with thermostat
RC 21 Remote controller is an optional accessory to the Controller, not
supplied with the Controller as standard. The Controller is fully operational
without the RC21.
The room un it permits comfortable adjustment of heating from within your living space.
The front side accommodates a sliding mode switch and a dial to control the parallel shift
of a weather compensated heating curve. Inside there is a temperature sensor.
The dial is used for parallel shift of a heating curve. The ow temperature is raised or
lowered respectively by your adjustment. When the dial is turned all the way down,
the heating circuit is switched off. Frost protection stays active to prevent damage.
Sensor
The RC21 contains a temperature sensor which is used by the controller.
If the settings in the controller allow it, the sensor is used to modify the ow temperature.
The switch changes the operation mode of the controller.
In Auto - Timer mode the
temperature is controlled according to
the set thermostat periods.
In Continuous day mode the
set periods are ignored and the
temperature is controlled according to
the Day time settings.
In Continuous night mode the
temperature is usually set to lowest.
This setting is best suited for periods of
long absence like e.g. holidays.
Installation
Carefully remove the dial from the casing with a screwdriver. Loosen the screw beneath.
Remove the bright part of the casing from the black socket.
The RC21 is connected via terminal block to the controller.
The RC21 is suited for low voltage only!

The display (1) shows graphic and text info on the hydraulic variant, set and measured values and other text
info.
The LED lamp (2):
lights up green - if a relay is closed and the
controller works right
lights up red - if the controller is set to
automatic operation and all

is set
ashes quickly red - if an error occurred
Entries are made using four keys.
In the picture there is an „esc“ key (3) and 3 other
keys (4). The „esc” key (3) is used to cancel an entry
or to exit a menu. If applicable there will be a request
for conrmation as to whether the changes which
have been made should be saved.
The function of each of the other three keys (4) is
shown in the display line directly above the keys;
the right-hand key generally has a conrmation and
