These installaon and operang instrucons contain basic instrucons and important informaon regarding safety, installaon, commissioning,
maintenance and the opmal use of the unit. Therefore these instrucons must be read completely and understood by the installaon technician/
specialist and by the system user before installaon, commissioning and operaon of the unit.
The valid accident prevenon regulaons, VDE regulaons, the regulaons of the local power ulity, the applicable DIN-EN standards and the
installaon and operang instrucon of the addional system components must also be observed. The controller does not under any circumstances
replace any safety devices to be provided by the customer! Installaon, electrical connecon, commissioning and maintenance of the unit may only
be carried out by specialists who possess the appropriate training.
For the user: Make sure that the specialist gives you detailed informaon on the funcon and operaon of the controller. Always keep these instruc-
ons in the vicinity of the controller.

The Temperature Dierence Controller LTDC facilitates ecient use and funcon control of your solar or heang system. The device is impressive
most of all for its funconality and simple, almost self-explanatory operaon. For each step in the input process the individual entry keys are as-
signed to appropriate funcons and explained. The controller menu contains headwords for the measured values and sengs, as well as help texts
or clearly-structured graphics.
The LTDC 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 characteriscs of the LTDC :
- Depicon of graphics and texts in a lighted display
- Simple viewing of the current measurement values
- Analysis and monitoring of the system by means of stascal graphics,etc.
- Individual conguraon of special funcons
- Extensive seng menus with explanaons
- Menu block can be acvated to prevent unintenonal seng changes
- Reseng to previously selected values or factory sengs
- A wide range of addional funcons are available.
The controller is available 4 dierent versions. See page 3.

B.5 DISPOSAL AND POLLUTANTS
The unit conforms to the European RoHS direcve 2002/95/EC for the restricon of the use of certain hazardous substances in electrical and elec-
tronic equipment.
CAUTION
The unit must not under any circumstances be disposed of with ordinary household refuse. Dispose of the unit only at appropriate
collecon points or ship it back to the seller or manufacturer.

DANGER
Before working on the unit, switch o the power supply and secure it against being switched on again! Check for the absence of
power!
Electrical connecons may only be made by a specialist and in compliance with the applicable regulaons. Do not use the control-
ler if the housing shows visible damage.
CAUTION
The cables being connected to the unit must not be stripped by more than 55mm, and the cable jacket must each into the housing
just to the other side of the strain relief.
CAUTION
Controller and VFS sensor have to have the same ground potenal. The VFS sensor has a funconal earth connector (PELV). The
PE-connector of the controller has to be connected to the pipe system near the sensor.
CAUTION
Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed temperature
sensor cables only into the le-hand side of the unit, and mains voltage cables only into the right-hand side.
CAUTION
The customer must provide an all-pole disconnecng device, e.g. a heang emergency switch.

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 posion and mark the 3
mounng 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 ghten the three screws.

The controller operates with Pt1000 temperature sensors which are accurate to the degree, thus ensuring opmal control of system funcons.
CAUTION
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
Sensor cables for S1 and S5 can be extended to a maximum of 30m using a cable with a cross-secon 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-secon of at least 0.75mm². Make
sure that there is no contact resistance!
CAUTION
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  ow direcon!
CAUTION
Posion the sensor precisely in the area to be measured! Only use immersion, pipe-mounted or at-mounted sensor suitable for
the specic area of applicaon with the appropriate permissible temperature range.
