Free-cooling
1.- OPERATION.
The control compares the values of temperature between outside air and room air by means of the probes; if there
is a negative difference and the safety elements allow (discharge temperature probes) then the control acts on the
servomotor, which opens the outside damper and closes the return damper, allowing cool outside air to enter the
room.
The damper is proportionally regulated. If there is not a great demand for air indoors, it may be enough just to have
free cooling to condition the room. If there is a greater demand for air, the free cooling and the unit may need to be
working in different cooling mode stages.
2.- SUPPLY AND INSTALLATION.
The free cooling option will be supplied loose.
The return probe must be installed in the return air intake duct.
