Heat quantity counter HQC: 30 ON/OFF Sensor supply line Sensor return line Volume flow encoder available No volume flow encoder Share of antifreeze Temperature difference adjustment Litres per pulse Share of antifreeze Sensor adjustment Reset counter Fixed volume flow Share of antifreeze Reset counter
The device also has a function to count the heat quantity. It is disabled ex works. A heat quantity counter basically requires three types of information: supply line temperature, return line temperature, and flow rate (volume flow) In solar thermal systems, the correct installation of sensors (see sensor installation - collector sensor on the supply line’s collecting tube, tank sensor on the outlet of the return line) automatically leads to correct measurements of the required temperatures, though the losses in the supply line will be included in the heat quantity. To increase accuracy, in indication of the share of antifreeze in the heat transfer medium is necessary as the antifreeze lowers heat conduction. The flow rate can be entered directly or via an additional sensor if the impulse rate is given. ON/OFF select / disable heat counter (ex works = OFF) S SL Sensor input for supply line temperature (ex works = S1) S RL Sensor input for return line temperature (ex works = S2) VSG Sensor input for volume flow encoder. As only input 3 is prepared as a pulse input, it is the only one that can be selected. (ex works = --) Settings: S VF 3 = volume flow encoder at input 3. S VF -- = no volume flow encoder � fixed volume flow. For the calculation of the heat amount, the set volume flow is only used if the set output is active. (pump is running) LPP Litres per pulse = the volume flow encoder’s pulse rate (only when a volume flow encoder is used) It depends on the system. The sensor supplied by the manufacturer of the control unit has a pulse rate of 0.5 litres per pulse. (ex works = 0.5) Setting range: 0.0 to 10.0 litres/pulse in increments of 0.1 litre/pulse V Volume flow in litres per hour. If no volume flow encoder has been set, a fixed volume flow can be preset in this menu. If a set output is not active, the volume flow is assumed to be 0 litres/hour. As activated speed control can produce constant changes in volume flow, this method is not suited to use with speed control. (ex works = 50 l/h) Setting range: 0 to 20000 litres/hour in increments of 10 litre/hour SA Share of antifreeze in the heat transfer medium. An average has been calculated from the product specifications of all of the major manufacturers; this average is used in the table of mixing ratios. This method generally produces an additional maximum error of one percent. (ex works = 0%) Setting range: 0 to 100% in increments of 1% 31
