Energy production counter principle.6.11 Admin parameters6.11.1 External fan controlP2.11.1.1 Start tempID 1727The temperature level of the inverter unit, at which the external fan control signal will beactivated. The external fan signal can be selected for any digital/relay output.P2.11.1.2 Stop tempID 1734The temperature level of the inverter unit, at which the external fan control signal will bedeactivated.Notice! The deactivation can also be delayed with the "Stop Delay" parameters. (If theinverter stops the unit temperature might decrease much faster than e.g. the LCL's, thena delay to get some more cooling time might be appropriate.)The external fan signal canbe selected for any digital/relay output.P2.11.1.3 Stop delayID 1857The deactivation of the external fan control signal after unit temperature has decreasedbelow "Stop Temp" can be delayed with this parameter. (If the inverter stops the unittemperature might decrease much faster than e.g. the LCL's, then a delay to get somemore cooling time might be appropriate.)The external fan signal can be selected for anydigital/relay output.
