Page 4: Safety Requirements
Safety requirements All installation and wiring work on the controller must only be carried out in a zero volt state. The opening, connection and commissioning of the device may only be carried out by competent personnel. While doing so, they must observe all local safety requirements. This device is state of the art and meets all necessary safety regulations. -

Page 16: Set Values (Max, Min, Diff)
Set values (max, min, diff) The device does not have any switching differentials (difference between temperatures to switch on or off); rather, all of the threshold values are divided into switch-on and switch-off values. In addition, some programs have several similar thresholds such as max1, max2. To make a distinction, the in- dex for max is also displayed in the same line. - Page 17 Schematic representation of setting values...

Page 23: External Sensors Ext Dl
Due to the relatively high power requirement, the “bus load” must be considered: The controller ESR32 delivers the maximum bus load 100%. For example, the electronic sensor FTS4- 50DL has a bus load of 25%, therefore up to a max. 4 FTS4-50DL can be connected to the DL bus. -

System protection functions Collector excess Frost protection temperature limiter Collector excess temperature limit OVER T Steam builds up when the system is not circulating. When it automatically switches on again, the pump does not have the pressure to lift the fluid level above the highest point in the system (collector feed line). -
Page 25: Collector Frost Protection Frost
Collector frost protection FROST This function is disabled ex works and is only necessary for solar power systems that run without antifreeze: In the south, the energy from the solar tank suffices to keep the collector at a minimum temperature for the few hours below freezing. At min of 2°C on the collector sensor, the settings in the chart release the solar pump and block it again at min ... -
Page 26: Start Function Startf
Start function STARTF (ideal for tube collectors) Solar thermal systems sometimes start too late in the morning when the collector sensor does not come into contact with the warm heat transfer medium in time. Flat collector fields or vacuum tubes with forced circulation often lack sufficient gravity pull. - Page 27 ON / OFF Start function ON/OFF Indicates a sensor input if a radiation sensor is used.

Page 28: Run-On Time
Run-on time During the start phase, the pumps may repeatedly switch on and off for a long time, especially with solar and heating systems with long hydraulic system lines. This response can be reduced by using a speed control or increasing the pump after-run time. If the control output is allocated to the output and no absolute value control, differential control or event control is activated, the analogue level for the maximum speed is additionally issued at the control output. -

Page 32: Absolute Value Control
Absolute value control = maintaining a sensor S1 can be kept at one temperature (such as 50°C) very well by using the speed control. If the solar radiation is reduced, S1 becomes colder. The control unit then lowers the speed and hence the flow rate. -
Page 33: Differential Control
Differential control = maintaining the difference between two sensors’ temperatures Keeping the temperature difference constant between S1 and S2, for instance, allow for “shifting” op- eration of the collector. If S1 drops due to lower irradiation, the difference between S1 and S2 thus drops. -
Page 34: Ereignisregelung
Ereignisregelung = If a set temperature event occurs, the speed control starts, thus keeping a sensor constant. If, for instance, S3 reaches 60°C (activation threshold), the collector should be kept at a certain tem- perature. Maintaining a sensor then works as with absolute value control. Example: ... -
Page 35: Stability
Stability The speed control has a PID controller. It ensures an exact and fast adjustment of the actual value to the set point. In applications such as solar power systems or feed pumps, the following param- eters should be left in factory settings. With a few exceptions, the system will run stably. These two values have to be balanced, however, especially for hygienic hot water from the external heat ex- changer. -
Page 36: Output Mode, Output Limits
Output mode, output limits Depending on the pump version, the control mode of the pump can be normal (0 – 100 “solar mode“) or inverse (100 – 0, “heating mode“). There can also be specific requirements for the limits of the control range. -
Page 37: Function Check F Chck
Some countries only offer subsidies for the installation of solar thermal systems if the control units have a function check to detect a sensor defect and a lack of circulation. In the menu command F CHCK, the mechanic can activate this function check for the ESR32. This function check is disabled ex works. -

Page 41: Step By Step Setup Of The Heat Meter
Step by step setup of the heat meter You have the option of using 2 different volume flow encoders: • the pulse encoder VSG and • the FTS-DL, which is connected to the data link. If you do not use a volume flow encoder, then you can only set a fixed volume flow. In the following, the necessary settings are displayed step by step.. - Page 42 FTS-DL Example: fitting in the return, use of an external sensor for the flow line which is connected to the FTS4-50DL The FTS4-50DL is connected to the data link (external sensor), hence: menu “EXT DL”, setting of the volume flow encoder on the display of the external sensor “E1“: 101 (address 1, index 01) Setting the sensor temperature of the FTS4-50DL for the return: menu “EXT DL”, on the display „E2“: 102 (address 1, index 02)

Page 44: Status Display Stat
Status display Stat The status display provides information in special system situations and problems. It is mostly in- tended for use with solar thermal systems, but can also be useful with other diagrams.

Page 47: Installation Instructions
Installation instructions Sensor installation The sensors must be properly arranged and installed for the system to function correctly. • Collector sensor: Either insert the sensor in a pipe directly soldered or riveted to the absorber and extending out of the collector casing or screw the sensor onto a T piece on the end of the supply line’s collecting tube using an immersion sleeve. -
Page 48: Installing The Device
Installing the device WARNING! Always pull the mains plug before opening the casing! Only work on the inside of the control system when it is without voltage. Loosen the screw on the top of the casing and remove the lid. The electronics for the control unit is in the lid. -
Page 49: Special Terminals
The bi-directional data link (DL-Bus) was developed for the ESR/UVR series and is only compatible with products of the Technische Alternative company. Any cable with a cross section of 0.75 mm² can be used for the data link (e.g. twin-strand) having a max. length of 30 m. For longer cables, we recommend the use of shielded cable. -

Tips on troubleshooting In general, all of the settings in the menus Par and Men and the terminal should first be checked if there is a malfunction. Malfunction, but “realistic” temperature values: • Check program number. • Check the switch-on and switch-off thresholds and the set differential temperatures. Have the thermostat and differential thresholds already been reached? •... -
