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 firmly 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.
Note!
The electrical equipment of the device must be installed firmly and connected to the power supply via a disconnector ensuring complete isolation from the power supply according to the erection regulations!
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 mm
2
is recommended.
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!

Volumetric flow sensor:
Measurement of solar radiation (heat quantity):
The solar yield is calculated from the flow rate and the differential temperature.
The differential temperature is the difference in the temperature of the collector sensor and the solar circuit return line sensor. There are various technical options: a) Use of a vortex volumetric flow sensor with 2 analog signals for flow rate and temperature. The vortex sensor can be inserted directly at the plug connector provided behind the TS terminals. All plant layouts (systems) permit solar radiation.
Pin assignment b) Impeller sensor (incrementation input)
An impeller sensor can be connected to TS6/TS7/TS8/TS10 and must be adjusted during installation. The temperature sensor for the solar return line must be set in the menu ›1.1.4 Heat quantities‹.
Solar yield measurement with impeller sensors is possible for all systems.
High-efficiency pump:
A high-efficiency pump can be connected via RO1 to RO4.
The appropriate control signal is issued at TS7 to TS10.
Thus, TS7 to TS10 is no longer available as input.
The control signal may be an analog voltage 0 - 10V or a PWM signal.

Connection to power supply
The strain relief device can only ensure solid clamping if the cables are not stripped to a length of over 35 mm.
Insulation of the individual wires must be removed over a length of 9 - 10 mm to ensure safe electric contact in the spring-type terminal.
Stranded wires must be provided with cable end sleeves!
9-10 mm max.
35 mm
For connection, press the actuation pushbutton of the spring-type terminal using a screwdriver and insert the wire to its stop in the appropriate port.
Release the actuation pushbutton and pull the cable slightly to ensure that it is safely clamped.
Important!
Before closing the terminal cover, make sure the strain relief device is tightened safely.
Check once more that all cables are in good condition and connected correctly.
18
Data interfaces
The solar controller has the following data interfaces:
The cut-outs at the left of the housing base accommodate a
USB port as well as a slot for a storage medium (SD card).
These interfaces are used, for example, for reading of error messages or log data or loading of software updates.
The USB port provides access to the SD card.
Only SD cards approved by emz must be used.
The controller automatically detects the SD card.
Prior to removing the SD card
›Rem.SD card safely‹ must be selected in ›1.2 Settings‹, otherwise data loss may occur.

Functions for boiler control
The functions for boiler control are accomplished via the potential-free relay contact which is connected accordingly to the relevant interface of the heating boiler.
The individual functions are assigned the following priorities:
A Anti-legionella priority 1
B recharge suppression priority 2
C reheating priority 3
Boiler
Anti-legionella function
The anti-legionella functions checks if the minimum heating for reduction of legionella has been achieved in the tank due to heating activity or solar heat within a set interval. f no sufficient heating has been achieved by these means the controller starts a reheat cycle, specifically for reduction of legionella.
The fitter must set the parameters based on the applicable general directives and local requirements. The time of the disinfection cycle can be determined freely.
Reheat function
The temperature sensor in the upper tank area supplies the values for reheating.
For oil or gas operated systems, reheating takes place via the heating boiler.
For solid-fuel boilers, reheating takes place via the heat present in the drinking water tank. To this effect, the temperature within the tank must be within preset limits.
The temperature control is interlinked with six time blocks.
Reheating is activated as soon as the temperature falls below the set value by the hysteresis value in the current time block.
When the set value is exceeded the reheating cycle stops.
Disable recharge
The efficiency of a solar plant increases as the recharge of the tank from the boiler decreases. Consequently, „disable recharge“ means that recharging of the water tank is blocked by the boiler.
Time-controlled disable recharge
Recharge is blocked by the boiler for specific phases via a time program.
Within the preset period of time (for ex. 7 to 19 h), recharge is blocked completely by the boiler without requiring the minimum temperature to this effect.
51
Functions for boiler control
Time-/temperature-controlled disable recharge
If a minimum temperature in the tank is exceeded, disable recharge is activated.
This function can be activated in parallel to the time program.
If the preset minimum temperature (e. g. 45°C) in the tank is exceeded, recharge of the tank is disabled by the boiler.
If, however, the minimum temperature is no longer reached, recharge is enabled by the boiler no matter whether the time program blocks recharge or not.
Efficiency-optimized recharge suppression
If the calculated minimum temperature in the buffer tank is exceeded, the disabled recharge feature is activated. The installer can specify two weighting factors in menu 1.4.3 for the calculation of this minimum temperature:
Factor 1
Solar yield
Parameter values from 1-10 whereby:
1 = more solar yield, less recharge by the boiler
:
10 = less solar yield, more recharge by the boiler
Factor 2
Comfort
Parameter values from 1-10 whereby:
1 = lower comfort, less recharge by the boiler
:
10 = higher comfort, more recharge by the boiler
Q
Solar energy history t
Factor 2 = 5
t
T
T min. tank (e.g.35°C)

A flexible minimum temperature is thus calculated once per day which disables the recharge by the boiler.
This flexible minimum temperature is between
›T min. tank‹ and ›T target‹.

Functions for boiler control
Note!
For boilers without control input, the functions for boiler control can be accessed by the simulation of temperature values.
To enable reheating or anti-legionella functions, the corresponding boiler temperature must be increased at the boiler control.
The differential temperature controller smart Sol plus regulates the boiler control functions by a fixed value resistance simulating a charged buffer tank for the boiler.
The resistance value depends on the type of sensor the heating is adjusted to - this information is provided in the boiler manual.

Soft water station AQA solar
In a specific equipment version (with an extension module), the differential temperature controller smart Sol plus can be connected to the soft water station
AQA solar of BWT Wassertechnik GmbH, Schriesheim.
AQA solar is a decalcification plant based on an ion exchanger, which ensures that the water lines and heat exchangers in your home are not damaged by scaling.
In case of very intense temporary heating of the drinking water, especially with thermal solar systems, decalcification is very useful to maintain efficiency.
Setup and operation of the equipment combination smart Sol plus and AQA solar is described in separate documentation and/or the operating manual of BWT.
For connection, the terminals
›Tx‹, ›Rx‹ and ›Gnd‹ above the interface terminals TS1 to TS10 are provided on the extension modules.

Danger!
Mortal danger due to electrocution! Before opening the terminal cover, disconnect the power supply reliably!
To remove the device fuse, open the terminal cover.
Above the right-hand group of terminals, the fuse base and a spare fuse are located. Pull the upper part of the support and the spare part out.
The fuse link is clamped in the formed piece and is removed together with the plastic holder.
Now, push the micro-fuse laterally out of its holder.
The fuse link is installed by reversing the above order.
Make sure to procure yourself immediately a new spare fuse!
Danger!
Risk of fire due to overload or short-circuit!
Only use fuse links type 5 x 20 mm, T4A!

Professional mode
Important!
In professional mode, settings are made which require detailed knowledge of the heating and solar plant.
Moreover, solid specialist knowledge regarding control engineering, hydraulics and solar thermal water heating is required!
If a single parameter is changed, this may affect the safety, function and efficiency of the entire plant!
Leave the settings in professional mode to a specialist workshop, the fitter or heating installer!
Modifications by non-experts tend to result in damage to the plant, rather than to an improvement of its efficiency!
