4.2.4 Condenser fan
The speed of the condenser fan can be controlled in order to save energy, reduce noise and opti-
mize the fan operation.
The fan is synchronized with the compressor operation.
Start and stop delays can be set up as a function of the state of the parameter Thermostat.
Furthermore, the fan can be set to run continuously (forced ON operation).
Some fan defects are detectable, and are displayed in the parameter Error.
The speed of the fan can be controlled in the range from 40% to 100%.
For 12 V DC systems 12 V DC fans should be used, and correspondingly for 24 V DC systems, 24 V
fans should be used.
