Important fundamental information
These instructions describe installation, commissioning, operation, repair
and disassembly of the differential temperature controller smart Sol plus for
solar thermal plants.
For operation of the entire plant, the technical documentation of all the
components used such as solar collectors, boiler, tank, pumps, mixers
and valves etc. must be complied with.
The controller is handled by the operator of the entire solar
thermal plant, i. e. as a rule by technical non-experts.
Make sure not to use the controller until you have thoroughly read and
understood these Assembly and Operating Instructions and the safety provisions.
Comply with all safety provisions and involve a specialist in case of doubt.
Keep these Assembly and Operating Instructions and all reference
documents so that they are available if required.
When relocating or when selling the device, hand the documents over to your successor.
Important!
The tter installing the controller must inform the plant operator about
operation, functioning and the method of action of the smart Sol plus!
Danger!
The device in operation may only be made accessible to
adults disposing of appropriate knowledge and experience!
Danger!
The controller by no means replaces the safety
components required under plant engineering aspects!
Danger!
Assembly, connection, commissioning, repair and disassembly of
the controller may only be performed by a qualied specialist!

Symbols used
When handling the differential temperature controller smart Sol plus
and the entire plant, please make sure that the following safety provisions
in the Assembly and Operating Instructions are complied with!
Note!
Useful information regarding handling of the device and the plant!

Description
The differential temperature controller smart Sol plusis an independent electronic
controller for surface-mounting which is used for the control of solar thermal plants.
The controller is equipped with a robust three-part plastic housing
which can only be opened by means of tools (screw driver PH2).
Operation is effected by means of only two control elements;
indications appear against a backlit colour display.
Before connection of the electrical system, the controller
must be mounted rmly to a perpendicular, robust surface (wall).
For its own supply and the supply of the outputs, the controller must be connected
to an electrical energy supply system in accordance with the technical data.
Assembly, connection, commissioning, repair and disassembly
of the controller are only admissible in a specialist workshop.
To ensure correct operation, temperature sensors type Pt 1000
must be used - the sensor design does not affect function.
Each temperature sensor has two connectors which are equivalent,
i. e. interchangeable. Thus, polarity reversal is not an issue.
The sensor lines can be extended up to a length of 100 m, to
this effect, a cable cross section of 2 x 1.5 mm2is recommended.
Note!
The electrical equipment of the device must be installed rmly and
connected to the power supply via a disconnector ensuring complete
isolation from the power supply according to the erection regulations!
Important!
Make sure that only a dry or slightly moistened cloth is used for cleaning
and servicing of the housing, the control elements and the display.
The surfaces must never get into contact with cleaning products
or solvents - mat, brittle or slightly dissolved plastic parts must
be replaced immediately!
A device with damaged housing must not be operated!

Technical Data
Intended Use
The differential temperature controller may be used exclusively as controller for the con-
trol of solar thermal plants. It must be operated within the scope of all the specications
described. Installation and set-up of the controller may only be performed by specialists.
The tter must have read and understood the operating manual.
The tter explains all the relevant functions to the operator.
For operation, it is essential that the housing is closed and free of damage.
