Programming Menu item 7.2.2.2.3 Designation other calculations. Warning: During the input, the blower should be switched off. If semi-automated flow calibration is performed (see 6.4.4 Performing calibration), calibration of the pressure sensor is automatically performed, too. Configure Options In the following chapters, the different options are explained in more detail. Menu item Inlet heating Heating controlled by ambient temperature Heating amplifier Heating capacity 7.2.2.2.3.2 Designation "on": Inlet heating is turned on, more options are available. "off": Inlet heating is turned off. "on": The power of the inlet heating is controlled by ambient temperature, For this, an outside temperature / pressure module has to be installed. "off": The inlet heating is driven by a constant power which can be chosen in this menu. This setting is only available when the inlet heating is controlled by ambient temperature. "on": the heating is controlled in a way that the power is 100% at outside temperatures under –10°C and 0% at over 10°C. "off": "on": the heating is controlled in a way that the power is 100% at outside temperatures under –20°C and 0% at over 20°C. This setting is only available if the inlet heating is not controlled by ambient temperature. The heating is operated with the set power of heating. Ambient pressure / temperature measurement In the following table, the options for ambient pressure and temperature measurement are explained in more detail. 7.2.2.2.3.1 Inlet heating The heating of the inlet can be controlled depending on outside temperature if an ambient pressure/temperature module is connected. 27 DIGITEL Elektronik AG Alte Gasse 18 CH-8604 Hegnau Tel.: +41 (44) 908 20 30 DIGITEL Elektronik GmbH Illstrasse 30 A-6706 Bürs Tel.: +43 (5552) 67850 www.digitel-ag.com [email protected]
