Onko sinulla tuo B21 lämpöanturi koneessasi tehtaalla asennettuna? Minulla ei ollut, mutta 10 k NTC-vastus maksoi 50 senttiä
Auttaako tämä:
The automatic correction is achieved by using the same values to control and calculate the yearly performance factor at the same temperature for the flow and return sensor. A calibration using absolute temperatures is not done.
Both sensor elements must be brought to the same temperature prior to the automatic correction.

"now"
The setting "now" triggers automatic sensor correction. During calibration, the "Readjustment HP flow sensor" is set based on measured temperature difference between flow and return sensor.
TreadjB21 = TreadjB71 + (TB71 - TB21)
Both sensor values must be with a range of 5°C and 50°C to calibrate and may not exceed a difference of max. 3°C.

"After pump prerun"
The condenser pump Q9 is first switched on for eight minutes and then the calibration is conducted if "After pump prerun" is selected.
The controller automatically activates the function "Relay test Q9" to switch on the condenser pump. As a result, the key symbol and special operating mode "output test" is displayed during this period. The prerun time cannot be adjusted.
The readjustment can be forced immediately and at any time during the pump prerun by selecting "now". "Off" aborts prerun without readjustment.
The automatic readjustment of return sensor B71 must be calibrated manually if you want a calibration of absolute temperatures. The readjustment value of the return sensor is not changed for automatic readjustment.
NOTE:
The menu Input / output test displays the measured sensor values without readjustment. The readjusted temperature values used for control are displayed in the menu Diagnostics heat generation.
