Explanation:
Range: Measurement channel:
The character indicates that the control in question is not in use. -
Outdoor temperature
Supply air temperature
Supply air temperature before the cooling cell
(taking into account the process delay caused by the cooling cell during the heating period).
The controller changes the ”Supply tempB” sensor to be a controlling sensor when the
”Supply temp” deviates from the ”Supply temp B” by over 6 °C and the outdoor temperature is
below the cooling ”Outd.Inhibit”set value. Control switches back to the ”Supply temp” sensor
when the amount of deviation has been less than 5.5°C for 6 minutes.
