6.2.6.1 Cooling
Press key to choose the cooling mode desired:
(manual)
The machine starts cooling function.
If the probe detects, inside the building, a humidity value 5% more than the value setted, the machine
goes in ventilation mode (cooling stand-by). If the probe detects, inside the building, a humidity
value less than value setted, the machine goes back in cooling mode.
It's possible to set the air flow by choosing the fan speed by using the
It's also possible to set automatic speed function FA (see next part).
To guarantee pads longer life, the evaporative cooler has the tank's water changes every 4 hours
(factory default) and a pads self cleaning cycle when the machine is switched off:
Every 4 hours, the machine goes in cooling stand-by (ventilation mode). It drains water from its tank
and re-fills it with fresh water, then goes back in cooling mode. (Elapsing time between the tank's
water change can be modified depending on environmental conditions and/or kind of water inlet.
To make this change, it's necessary to call Mark Climate Technology). Every time the evaporative
cooler is switched off, it starts a pads self clearing cycle 10 minutes long. It drains water from its tank
and re-fills it with fresh water, than it starts water recirculation through the pads (ventilation off) to
remove residual salts and other kind of dirtiness. At the end of cycle the machine drains the water
from the tank.

Air flow during automatic speed function (FA) depends on the setted temperature value
and the temperature value detected by the probe. If the probe detects, inside the building, a
temperature value higher than the value setted, the fan start on higher speed until it reaches the
setted temperature value. When the temperature is reached, the fan goes on lower speed. If the
temperature rises up, the fan goes on higher speed. The fan will go on as described before.
