TWO INDEPENDENT ZONED NATURAL VENTILATION OUTPUTS
Two independent natural ventilation outputs allow the controller to ad-
just the curtain opening according to the temperature of each zone.
OUTSIDE TEMPERATURE COMPENSATION ON NATURAL
VENTILATION OUTPUTS
The curtain timer settings are compensated proportionally to the out-
side temperature. The lower the outside temperature, the faster the cur-
tains close. The higher the outside temperature, the faster the curtains
open.
FULL SPEED FAN START UP
In order to overcome the inertia of the ventilation system components
and de-ice the fan blades in cold weather conditions, the controller sup-
plies maximum voltage to the variable speed fans during 2 sec-
onds at each start-up.
OVERLOAD AND OVERVOLTAGE PROTECTION
Fuses located at the input and outputs of the controller protect its cir-
cuitry in the case of an overload or overvoltage.
COMPUTER CONTROL
When used with a communication module, the controller communi-
cates with a computer. This makes possible the centralization of in-
formation management and a more diversified control strategy.
