The Temperature Difference Controller SR34 facilitates efficient use and function control of your solar or
heating system. The device is impressive most of all for its functionality and simple, almost self-explanatory
operation. 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.
The SR34 can be used as a solar controller for the various system variants illustrated and explained under
„D.2. - Hydraulic variants / systems“ on page 13.
Important characteristics of the SR34:
- Depiction of graphics and texts in a lighted display
- Simple viewing of the current measurement values
- Analysis and monitoring of the system by means of statistical graphics,etc.
- Individual configuration of special functions
- Extensive setting menus with explanations
- Menu block can be activated to prevent unintentional setting changes
- Resetting to previously selected values or factory settings
- A wide range of additional functions are available.
The controller is available in 4 different versions. See page 3.

B.4. - Scope of supply
B.5. - Disposal and pollutants
The unit conforms to the European RoHS directive 2002/95/EC for the restriction of the use of certain
hazardous substances in electrical and electronic equipment.
Caution
The unit must not under any circumstances be disposed of with ordinary household refuse.
Dispose of the unit only at appropriate collection points or ship it back to the seller or
manufacturer.

Installation
Controller and VFS sensor have to have the same ground potential. The VFS sensor uses a
functional earth connector (PELV). The PE-connector of the controller has to be connected
to the pipe system near the sensor.
Caution
C.1. - Electrical connection
Danger
Before working on the unit, switch off the power supply and secure it against being
switched on again! Check for the absence of power!
Electrical connections may only be made by a specialist and in compliance with the
applicable regulations.
Do not use the controller if the housing shows visible damage.
Caution
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.
Caution
The customer must provide an all-pole disconnecting device, e.g. a heating
emergency switch.
Caution
The cables being connected to the unit must not be stripped by more than 55mm, and the
cable jacket must reach into the housing just to the other side of the strain relief.

9
Installation
Install the controller only in dry areas and under the ambient conditions described under B.1
“Specifications”.
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.
Achtung

1. Select necessary
program/hydraulics
(s. „D.2. - Hydraulic
variants / systems“ on
page 13)
2. Strip cables by
55mmmax., insert, fit
the strain relief devices,
strip the last 8-9mm of
the wires (Fig. „C.2.3.“)
3. Open the terminals
using a suitable
screwdriver (Fig.
„C.2.4.“) and make
electrical connections
on the controller
4. Refit terminal
connection cover and
fasten screw.
5. Switch on mains voltage
and place controller in
operation.

C.2.4.
Installation
Instructions for clamps:
1. Insert screw driver into the upper
hole. Push the lock clamp inside
down.
Keep the screw driver in this position.
2. Insert cable into the lower opening.
3. Remove screw driver. The clamp will
lock the cable.

11
The temperature sensor cables must be routed separately from mains voltage cables,
and must not, for example, be routed in the same cable duct!
Caution
Caution
Caution
The controller operates with Pt1000 temperature sensors which are accurate to the degree, thus ensuring
optimal control of system functions.
Caution
Position the sensor precisely in the area to be measured!
Only use immersion, pipe-mounted or flat-mounted sensor suitable for the specific area
of application with the appropriate permissible temperature range.
Sensor cables for S1 and S5 can be extended to a maximum of 30m using a cable with a
cross-section of at least 0.75mm². Sensor cables for S2 to S4 and S6 can be extended to
a maximum of 10m using a cable with a cross-section of at least 0.75mm². Make sure that
there is no contact resistance!
Connect the VFS sensors with the matching jacks.
To prevent damage to the Direct Sensors it is highly recommended to install them in to
the return.
When installing the Vortex Flow Sensors (VFS), observe the correct flow direction!

Operation
E.2. - Commissioning help
takes you back step by step to the selection mode, thus cancelling the commissioning help. Finally, menu
„3.2. - Manual“ on page 24 should be used to test the switch outputs with the consumers connected, and
to check the sensor values for plausibility. Then switch on automatic mode.
The first time the controller is turned on and after the
language and time are set, a query appears as to
whether you want to parametrise 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
value so you can look at the selected setting again or
adjust it if desired. Pressing the “esc“ more than once
