INNOVATIONS

• Measuring of tensions (0V to 5V) is possible at all inputs. With it the interpretation of volume flow sensors, which output tensions instead of impulses, is possible. Interpretation of flow rates for heat quantity counters is only possible at inputs 1 to 14.

Even if the scaling is adjustable up to 10V, it must be sure, that maximal 5V are active at these inputs.

29.10.2007

MODIFICATIONS

• Modification of the setting range of pulse rate (l/pls) in pulse inputs (S15 or S16) and Measuring variable Flow rate to 0.5 – 100 l/pls. If set to >10l/pls the flow rate is displayed in l/min instead of l/h. Therewith it is possible to create a heat quantity counter up to a power of 3000 kW = 3MW.
• Bug-fix in handling counter in network (interval time and timeouts)

Version A2.20

26.06.2007

INNOVATIONS

• Possibility of logging two heat quantity counters (HQC) via DL bus:

Logging of network inputs must be set to “yes” (setting in output 14).

Data output UVR1611: The values of the first two HQC’s are output in the function list (as up to now); data output virtual UVR1611: The values of the third and fourth HQC are output in the function list. Thus it is possible to log a total of 4 HQC’s.

Typical application:

2 VSG’s (volume flow encoder) on inputs 15 and 16 of UVR1611;

2 VSG’s on inputs 3 and 4 of CAN I/O module;

4 functions Heat quantity counter at UVR1611.

MODIFICATIONS

• Network will be initialized 5 seconds after reset (up to now after 20 seconds).
• Calculation of functions starts 30 seconds after reset (up to now after 20 seconds).

Thus informations from inputs (not from output variables, which are calculated by functions) of other bus members (e.g., room temperature from CAN Monitor, outdoor temperature from another UVR1611) are available at the start of function calculation; thus a short switch on of burner requirement or heating circuit pump is avoided.
(needs CAN Monitors from version E2.00)

• Modification of function (OR, AND,...) in Logic function only possible as “Expert”.
• Bug-fix in calibration mode of function Heat quantity counter (HQC): The time, which should run from 60 to 0 seconds, was not 60 seconds but 4 minutes. This error had no effect to the calculation of HQC but only to time base of calibration mode. Bug since version A2.15.
• Bug-fix in output 14 (DL): Output 14 has been partly for 20 seconds „ON“ instead „OFF“ after controller start.

• Bug-fix in display of Function overview: Instead of error message “Timeout”, dimension and number of input variable was displayed. Bug since version A2.16.
• After change of controller node number the CAN bus will be initialized. Thereby the problem, that the access to network nodes, with which the user was connected during change of node number, was no longer possible, is solved. (Bug concerns only controllers in a CAN network).
• Bug-fix in switching over to Function overview in combination of manual controlling of mixer outputs: When the mixer is manuallycontrolled for longer time, the controller has switched over to Function overview anyway.
• Increasing the time after which the controller restarts automatically from 1 minute up to 2 minutes (after selection of function data transfer or operating system update by Bootloader)

2.    Update Bootloader to V2.3

3.    Install controller operating system A2.15

4.    If in use: Update of CAN Monitor to E1.13

INNOVATIONS

• Simulation mode in User menu available (only as „Expert“):

- no average determination of outdoor temperature in Heating circuit controller

- Inputs defined as PT1000 sensors are measured as KTY sensors

- no RAS interpretation

- The simulation mode will be finished automatically when changing to operating mode “Client” or “Technician” or after power blackout!

• Display of remaining minimum burner runtime in function status of function Heating requirement.
• Addition of new Switch-off conditions in Heating circuit controller:

Switch off the heating circuit pump, when the actual flow temperatureT.FlowACT is larger than T.FlowMAX + fixed hysteresis 3K. Pump will be released when T.FlowACT<T.FlowMAX.

• Possibility to transfer the status of the room sensor RAS via CAN bus (Status room sensor will be transferred automatically with the room temperature. Typical application: Heating circuit built up via CAN I/O Module, room sensor RAS can be connected now directly to CAN I/O module; it is not further necessary as up to now to connect the RAS directly to UVR1611. Needs CAN I/O Module version A1.02.)
• Possibility in Warm water requirement to start tank feeding onceby key press to set nominal temperature outside of programmed time programs.
• Input variable “External switch” now accepts also analog values for switching over the operating mode externally:

Value / Operating mode

64 / Stand-by/Frost protection

65 / Time/Automatic

66 / Normal

67 / Lowering

127 / Switch back to internal operation

For possible application via SMS with a later version of BL-NET.

MODIFICATIONS

• Setting range of P and I part of function PID control increased to maximal 100.
• Increase of setting range value “if enable = OFF” and value of input variables as User in Analog function in mode dimensionless.
• Increase of setting range for minimum burner runtime in function Heating requirement.
• Increase of setting range of limit temperature in Solar function to 150°C (necessary for integration solar electrical converters)
• Bug-fix in switch-on excess in combination with switch-off condition T.FlowNOM<T.FlowMIN:

When the heating circuit was switched-off because of the condition T.FlowNOM<T.FlowMIN, T.flow.NOM was calculated higher and higher by switch-on excess, which became after a certain time higher than T.FlowMIN. Thus the heating circuit pump switched on shortly and after it for a longer time off. E.g., the pump run for 3 minutes every 3 hours. Of course this time could vary depending on set values of switch-on excess and heat curve (T.FlowMIN). As for now the switch-off condition T.FlowNOM<T.FlowMIN will not be considered in connection to switch-on excess.

INCOMPATIBILITIES

• Setting of new switch-off conditions in Heating circuit controller: Switch off heating circuit pump if T.flowACT>T.FlowMAX (yes/now)
