6. Initial operation and system calibration 6.3.4 Detailed description of characteristic curve calibration Characteristic curve off calibrate Characteristic curve on calibrate Withdrawal starts Determining the operating points of the control system ■ Manual operation menu ■ Characteristic curve calibration submenu 1x Leave the info menu using the “escape” key 2x flashes 5x and then 1x flashes 1x 2x 1x Select the menu: manual operation Select the menu: manual operation ■ select using right key, OFF flashes. ■ Using the upper key, switch to On and ■ confirm twice with the right key. Calibration procedure starts. Kindly follow the menu guidance on the display. Consecutive drawn amounts of 25 litres, 8 litres and 4 litres are required. After the relevant operating points of the pump have been determined and independently logged into the control system, characteristic curve calibration “on” again appears on the display. Leave this submenu using the left key. The characteristic curve calibration is now complete. 13
7. System examples 7.1 Freshwater station with circulation in a time-slot and with tapping detection outside the time slot ■ Initial operation and system calibration from point 6 ■ Setting the time and date, point 5.3.3 ■ Domestic hot ■ set value e.g.: 50°C, point water 5.3.3 and 5.3.5 ■ Circulation ■ Basic setting menu, Circulation submenu = select “on”, point 5.3.5 ■ In programming menu, circulation submenu up to 3 select time slot, point 5.3.3 ■ Circulation temperature 40°C, for control in time slot, point 5.3.5 ■ Circulation time e.g.: 60 s, Circulation rest time.: e.g. 10 min, for controlling the circulation through tapping detection outside the time slot, point 5.3.5 ■ Heat transfer unit ■ WT = cold, point 5.3.3 ■ Time lag ■ e.g.: 20 s, point 5.3.5 7.2 Freshwater station with circulation only via tapping detection ■ Initial operation and system calibration from point 6 ■ Setting the time and date, point 5.3.3 ■ Domestic hot ■ set value e.g.: 50°C, water point 5.3.3 and 5.3.5 ■ Circulation ■ Basic setting menu, Circulation submenu = select “on”, point 5.3.5 ■ In programming menu, Circulation submenu is the start and stop times within each 3 time slots which are to be set at the same time e.g.: start 6h00 - stop 6h00 point 5.3.3 ■ Circulation time e.g.: 60 s, Circulation rest time e.g.: 10 min, point 5.3.5 ■ Heat transfer unit ■ WT = cold, point 5.3.3 ■ Time lag ■ e.g.: 20 s, point 5.3.5 14 7.3 Freshwater station without circulation ■ Initial operation and system calibration from point 6 ■ Setting the time and date, point 5.3.3 ■ Domestic hot ■ set value e.g.: 50°C, point water 5.3.3 and 5.3.5 ■ Circulation ■ Basic setting menu, Circulation submenu = select “off”, point 5.3.5 ■ Heat transfer unit ■ WT = cold can be selected, if the distance between the buffer and the freshwater station is not too great. After-run e.g.: 20 s, point 5.3.5 ■ WT = hot can be selected, if there is a great distance between the buffer and the freshwater station, and the comfort of the “rapid” hot water drawing has been attained. Set the after-run point 5.3.5 on nought, as no circulation pipe is available.
