  • Page 8: 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 9: Generally Applicable Rules

    Generally applicable rules For the proper use of this device The manufacturer’s warranty does not cover any indirect damage to the unit if the technician install- ing the unit does not equip it with any additional electromagnetic modules (thermostat, possibly in combination with a one-way valve) to protect the device from damage as a result of malfunction un- der the following circumstances: •...

  • Page 10: Step By Step" Setup Guide

    „Step by Step“ Setup guide The following guide might give you instructions on setting up the device, but it is of utmost importance to read the entirety of the instruction manual – especially the chapters „Pro- grams“ and „Operation“. Level Choose a hydraulic diagram based on the sketches of system dia- grams.

  • Page 11: Hydraulic Diagrams

    Hydraulic diagrams The hydraulic diagrams displayed in this booklet are practical sketches. They serve to ease the choice of the correct program, but don‘t replace or even describe the planning of your system‘s construction. As such, we can‘t guarantee your system‘s functionality if you imitate this booklet‘s hydraulic diagrams with your construction.

  • Page 60: Building Drying - General Information

    Building drying – General Information A special application of the universal controller UVR65 is the energy-saving and cost-effective drying of basements and other building parts via regulation of ventilation. The special functionality of the sensor RFS-DL (measurement of absolute humidity) enables the comparison of the values for abso- lute humidity indoors and outdoors to turn a fan on or off.

  • Page 61: Programs - Building Drying

    Choosing a building drying program automatically binds inputs and external sensors according to the table below to reduce the amount of necessary manual setup. These settings can of course be changed, if so desired. Input Ext. Sensor Value Absolute humidity indoors Absolute humidity outdoors Temp.

  • Page 80: Installation Instructions

    Installation instructions Sensor installation Correct arrangement and installation of the sensors is extremely important for correct func- tioning of the system. To this end, also ensure that they are completely inserted in their sen- sor wells. The cable fittings provided serve as strain relief. When used outdoors, no water must be allowed to penetrate the sensor wells (risk of frost).
  • Page 81 • DHW sensor: A rapid reaction to changes in the water volume is extremely important when using the controller in systems that generate domestic hot water by means of an external heat exchanger and variable speed pump (freshwater module). Therefore fit the DHW sensor directly on the heat exchanger outlet.

    Device installation CAUTION! Always disconnect the mains plug before opening the casing! Only work inside the controller with the power cable disconnected. Unscrew the screws on the front and lift the cover. The electronics are located in the cover. The connection to the terminals in the lower section of the enclosure is made by contact pins when the cover is put in place.

  • Page 113: Run-On Time

    Run-on time Especially solar and heating pumps with long hydraulic pipelines may have issues with con- stant turning on and off again over longer times when attempting to start up. This is espe- cially disadvantageous for modern high-efficiency pumps. Such behavior can be avoided by specific usage of the speed control or by setting up a run-on time.

  • Page 114: Control Output

    Control output The two control outputs (A4 and A5) are identical in terms of parameterization. The parameters concerning the control outputs are found in this menu. As analogue output, 0-10 V can be generated in 0.1 V steps. In the mode PWM, a digital signal with a frequency of 1 kHz (level approx. 10V) and a variable duty cycle of 0 to 100% is generated.

  • Page 115: Absolute Value Control

    This example will be used to describe the different possibilities for speed control. Absolute value control = maintaining a sensor‘s value S1 can be kept at a certain temperature (such as 50°C) very well by using the speed control. If the insolation sinks, S1 becomes colder. The control unit then lowers the speed and hence the flow rate.

  • Page 116: Differential Control

    Differential control = to keep the temperature between two sensors constant Keeping the temperature difference between two sensors, e.g. S1 and S2, allow for a „mod- ulating“ operation of the collector. If S1 drops due to sinking insolation, the difference be- tween S1 and S2 sinks as well.

  • Page 117: Event Control

    Event control If a set temperature threshold (set value event) is exceeded at the activation sensor, the event control starts, keeping the temperature at the control sensor constant (controller set value). If S3, as exemplified, reaches 60°C (activation threshold), the collector is to be held at a con- stant temperature.

  • Page 118: Stability Problems

    Stability problems The speed control contains a „PID controller“. It ensures an exact and fast adjustment of the actual value to the set value. In applications such as solar systems and charging pumps, the factory settings likely regulate in a stable manner. Especially the DHW preparation via external heat exchangers (fresh water station) adjusting these values to the specific circum- stances is absolutely necessary.

  • Page 119: Output Mode, Correcting Variables

    Output mode, Correcting variables Depending on the make of the pump, the control mode of the pump can be set to normal (0-100 „solar mode“, PWM 2) or inverse (100- 0 „heating mode“, PWM 1). There may also be specific require- ments for the limits of the control range.

  • Page 120: System Protection

    System protection There are two functions for excess collector temperature limitation, two for frost protection, and a cooling function. Except for the first excess temperature limitation, all of these func- tions are deactivated in the factory settings. Excess temp. limiter Steam might build up in an idle system, making a reactivation difficult, as the pump can‘t lift the fluid above the highest point in the system (the collector feed line).

  • Page 121: Frost Protection

    Frost protection This function is deactivated in the factory settings and only necessary for solar systems that have no frost protection of their own. Souther latitudes offer the possibility of bridging the gap of the few hours below a collector minimum temperature with power from the solar sys- tem‘s cylinder.

  • Page 122: Collector Cooling Function

    Collector cooling function Using this function, a solar system‘s cylinder can be cooled overnight to allow it to take in warmth again the next day. If the chosen sensor (cylinder temperature) exceeds the specified temperature, the speci- fied outputs will be activated within the specified time window until the temperature is un- derrun again.

    Start function (ideal for tube collectors) Some solar systems might not be sufficiently bathe the collec- tor sensor in the warmed heat transfer medium in the morning, resulting in an unfavorably late start of circulation. Flat collec- tor panels generally tend to lack sufficient gravitational force. The starting function attempts find a good point to activate the solar pump by constantly monitoring the collector‘s temperature.

    Heating characteristics The flow temperature is usually calculated from the temperature outdoors and the heat curve (settings: menu Technician level/Parameters, Control type: Temperature or Slope).

    Heat curve With both methods, the influence of the outside temperature on the flow temperature is not linear. For the mode Slope, the curvature is designed according to the norm. For the mode Temperature, the specification of the desired flow temperature at 10°C (outdoors) causes a „curvature of the heat curve“.
