Free Cooling Mode

During seasonal transitions for example, Spring and Autumn, when indoor and outdoor temperature difference are not signification, the unit automatically switch to Free Cooling Mode by opening the built-in bypass vent. The air will pass through this canal without going through the heat exchanger, thus reducing the stress on fans and operate on an even less power. This set temperature can be changed on the digital control panel to a desired level.

Defrost Mode

We suggest that you equip a pre-heater for uses below -3°C to avoid freezing inside the unit, however, to prevent this from happening when there is no heater attached, our devices automatically enter defrost mode when temperature requirements are not met. Defrost Mode adjusts intake and exhaust air rates to prevent icing and keep the device temperature at a safe level. We strongly advise using a preheater for climate condition below -10°C.
