FREELY PROGRAMMABLE UNIVERSAL
The UVR1611 unit is equipped with function modules offering the possibility of free programming
for each system configuration for heating space management. As each function module can be called
repeatedly, complex control systems such as solar systems with multiple collector panels and tanks or
multiple heating circuits controlled by atmospheric conditions can also be realised.
It offers the following features:
 16 sensor inputs for KTY10 or PT1000 sensors
(two of them also serving as pulse input and analogue input 4-20mA or 0-10V)
 4 speed-adjustable outputs and 7 relay outputs
 2 other outputs upgradable via a relay module
 Operation via scroll-wheel and large display
2 control outputs 0-10 V separately switchable to PWM
 CAN-Bus for data exchange to other and/or additional UVR1611 units
DL-Bus to capture respective sensors and to record data
 Infrared interface for software updates

  • Page 72: Pid Control (Speed Control)

    PID control PID control (speed control) The PID control can be used to change the delivered quantity – i.e. the volume flow – of usual com- mercial circulating pumps. That allows the system to maintain temperatures (differences). It can be used not only for the speed control but also for the control of the burner performance and others.
  • Page 73 PID control Waveform Two waveforms are available for motor control (in the menu “Outputs”). Wave packet - only for circulating pumps with standard motor dimensions. Here, individual half- waves are blended in to the pump motor. The pump is run via pulses, an the “smooth running” of the motor is only due to the moment of inertia.
  • Page 74 PID control Pump standstill The wave packet method (standard) allows the volume flow to be changed by a factor of 10 in 30 increments. If the flow rate is too low, return flaps may cause a standstill as well as a low output of the pump at low speeds of the control unit.
  • Page 75 PID control  Event control “overwrites” the results of speed control from other control processes. Hence, a set event can block the absolute value control or differential control. Example: Keeping the collector temperature at 60°C with the absolute value control is blocked when the tank has already reached 50°C at the top = the fast provision of warm water is complete and is now to be continued with full volume flow (and hence a lower temperature but slightly better efficiency).

Besides the heating circuit and load pump module this modules represents an extremely versatile and important link to the burner requirement.
  • Page 77 Analog function Example of use: The greatest temperature that the system currently demands is calculated from the three functions "heating circuit 1." "heating circuit 2" (output variable = pre-run nominal value), and burner require- ment warm water (output variable = effective tank temperature) so that the burner requirement is later correctly compared to the buffer tank temperature.

  • Page 79 Profile function Although the profile stage is registered every 6 hours in the internal storage, it gets lost while loading new function data (load factory settings, load backup copy, data transfer from boot loader). If an internal cycle > 23.5 hours is set (such as heat drying of a pavement floor), profile stage 1 is saved in the internal memory immediately after the profile function starts.

  • Page 86 Timer Instable: By indicating a switch-on and off time, a pulse generator is created without a trigger input. If the pulse-duty factor is also used for controls, it changes the switch-on time. The setting switch-off time = 0 is a special case: The switch-on time then corresponds to the entire period, and the pulse-duty factor to the relationship between the switch-on and the switch-off time Pulse: If the selected trigger slope occurs, the output for the timer time switches on.

    Maintenance Maintenance This function is intended as a service function for the chimney sweeper and/or as a simple burner switch for the exhaust measurement. The preset output (generally 100%) is switched on for the set time after the burner has been started. In addition, the heating circuits set in the input variables are activated with the maximum admissible pre-run temperature.

  • Page 92: Function Control

    Function control Function control In the solar and heating section, a number of functions perform important tasks that could lead to wrong reactions if there's a malfunction. For instance, if a defective tank sensor in the solar system detects temperatures that are too low, the solar system will run under false premises and take heat out of the tank.

  • Page 106: Installation Instructions

    Installation instructions Installation instructions Sensor installation The sensors must be arranged and installed properly for the system to function correctly. To this end, make sure also that they are completely inserted in the immersion sleeves. The threaded cable connec- tions provided serve as a strain relief. The clip-on sensors must be insulated to protect them from being influenced by the ambient temperature.
  • Page 107 Installation instructions  Warm water sensor: When the control system is used in warm water systems with an external heat exchanger and speed-controlled pump, changes in the amount of water have to be reacted to quickly. Hence, the warm water sensor has to be put directly on the heat exchanger’s outlet. A t-shaped connec- tor should be used to insert the ultrafast sensor (special accessory) in the outlet using an o-ring.

    Installation instructions Electrical connection It should only be made by a professional electrician in accordance with the relevant local guidelines. The sensor lines must not be laid in the same cable as the supply voltage (standard, regulations). In a commonly used cable channel, appropriate shielding has to be provided. Notice: The system has to be grounded properly to protect it from damage due to lightening.

  • Page 115: Tips On Troubleshooting

    Tips on troubleshooting If there is no display, there has been a power outage. First check the fuse (6.3A, quick-blow) that protects the device and the outputs (pumps, valves, etc.) from short circuits and the outputs in connec- tion with the integrated overvoltage protection. Realistic temperature values but outputs not operating properly indicate false settings or connec- tions.

    Maintenance The system does not require maintenance if handled and used properly. Use a cloth moistened with soft alcohol (such as spirit) to clean. Harsh solvents such as chlorethenes or tri-gases are not admissi- ble. As the components relevant to accuracy are not subjected to loads if used properly, long-term devia- tion is very low.
