  • Page 5: Safety Requirements

    Safety requirements: All installation and wiring work on the controller must only be carried out in a zero-volts state. The opening, connection and commissioning of the device may only be carried out by competent personnel. In so doing, all local security re- quirements must be adhered to.

  • Page 6: Generally Applicable Rules

    Generally applicable rules for the proper use of this unit:  When used for floor and wall heaters: here, a safety thermostat must be used just as with conventional heater controllers. It has to switch off the heating loop pump if there is overheating regardless of the output from the controller to prevent indirect damage from excess temperatures.

  • Page 35: Installing Instructions

    Installing instructions Installing instructions Installing the sensor(s): The sensors must be arranged and installed properly for the system to function correctly. To this end, make sure that they are completely inserted in the immersion sleeves. The threaded cable connections provided can be used to provide strain relief. The clip-on sensors must be insulated to protect them from being influenced by the ambient temperature.
  • Page 36 Installing instructions Hot water sensor: When the control system is used in hot water systems with an ex- ternal heat exchanger and variable-speed pump, changes in the amount of tempera- ture have to be reacted to quickly. Hence, the hot water sensor has to be put directly on the heat exchanger’s outlet.

  • Page 39: Selector Switch

    Selector switch Selector switch The selector switch has 16 different positions. Each position has two functions (e.g. switch position diff2 / T2). The value, which is nearer to the selector switch, will be displayed without pressing of the yellow key “Eingabe” (e.g. T2). By pressing the yellow key “Eingabe” (= in- put) the second value will be displayed (e.g.
  • Page 40 Selector switch diff: The output will be released, when the temperature difference between two set sensors exceeds this value. diff is the basic function (differential control) of this unit for most programs. Recommendation: In solar applications, diff should be set to 7 - 10K. Somewhat lower values suffice for the feed pump program.

  • Page 45: Sensor Type

    Additional functions Sensor type Solar collectors reach standstill temperatures of 200 to 300°C. No value above 200°C is expected due to the sensor installation point and physical properties (dry steam does not conduct heat well, for instance). The standard Pt1000 series sensors can be permanently exposed to 250°C and briefly to 300°C.

  • Page 46: Function Control

    Additional functions Function control Function control allows detection of sensor interruption or short circuit (error code FF1 – FF6), missing circulation caused by too high temperatures (>40K) between solar panel and consumer after 10 minutes pump-run (error code FF7) and circulation error (error code FF8) of the solar power system.

  • Page 47: Collector Excess Temperature Limit

    Additional functions Collector excess temperature limit 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). If there is no circulation, the load on the pump is enormous. This function allows the pump to be blocked above a set collector temperature threshold until a second set threshold is fallen short of.

  • Page 48: Start Function (Ideal For Tube Collectors)

    Additional functions Start function (ideal for tube collectors) In the morning, solar power systems sometimes do not “start” quickly enough because the warm heat transfer medium does not reach the collector sensor. Flat collector panels and forced-circulation vacuum tubes generally lack sufficient gravitational force.

  • Page 49: Priority Menu

    After the rinsing time (1, 3), the computer calculates the increase in collector temperature. It detects whether the set waiting time tA has been reached to heat the collector to the priority temperature. In the second case, the unit waits until the priority has been reached to switch.

  • Page 50: After-Running Time

    I.e. a thermostat with hysteresis 10K, which is set to 70°C, switches off at 70°C and switches on again at 60°C. Hystereses in UVR 64 are not constant, but they change accord- ing to the temperature and can be set from 1 to 9 K per 64°C.

  • Page 51: Pump Speed Control

    Additional functions Pump speed control The pump speed control can be used to change the delivered quantity - i.e. the volume flow - of usual commercial circulating pumps in 30 steps. This provides constant levels of (differen- tial) temperatures in the system. Setting of optional sensors and temperatures is possible.

  • Page 52: Differential Control F

    Additional functions Differential control F = keeps the temperature constant between two sensors. Keeping the temperature difference constant between T1 and T2, for instance, allows for “shifting” operation of the collector. If T1 drops due to lower irradiation, the difference be- tween T1 and T2 thus drops.

  • Page 53: Pump Standstill

    Additional functions Pump standstill The wave packet method (standard) allows for variations in the volume flow by a factor of 10 in 30 increments. If the flow rate is too low, flap valves may cause a system standstill. In addition, low power stages at low speeds may cause the rotors to stop. Such a standstill may sometimes be desired, which is why stage 0 is allowed as the lowest stage.

    Additional functions Pump speed processor A 2 – absolute value control: Sensor T2 being kept constant by pump speed. The speed increases as temperature T2 does. A-2 means that speed increases as temperature T2 drops (= inverse mode) ew = A 0 (switched off) c60 –...
