Changing fan speed as a percentage
BOOSTER FUNCTION
In detail, the possible options are as follows:
- off: fans are motionless with this option, but watch out that the unit is live anyway; this value is achieved by going below the minimum
speed value that can be set;
- xxx [%]: if the unit is equipped with continuously variable speed fans, a fan speed percentage, flow or a full-scale pressure (for units
not equipped with a specific kit, yet with a cop/cav version with a different sensor) value can be set starting from the minimum value
(factory setting) up to 100% of the available speed with 5% steps (1% on request);
-1, 2 or 3: if the unit is equipped with 3-speed fans, one of the available speeds can be selected: speed 1, speed 2 or speed 3.
- clock: with this option, the fan speed is controlled according to the weekly schedule (see Program menu). This value is achieved by
selecting a greater value than the maximum speed (100% or 3);
- auto: this option is only available when a sensor (CO
2
, CO
2
-VOC or RH relative humidity) is available on whose measure depends the
fan speed. If an external signal (0-10V) is used to control the fan speed, this value is obtained by selecting a greater value than clock.
- xxx [m³/h]: if the unit is in constant flow version (CAV) with kit, the desired value can be set in m3/h of flow. Fans will automatically run
at the speed corresponding to this flow according to the change in the load.
- xxx [Pa]: if the unit is in constant pressure version (COP) with kit, the desired value can be set in pascal of pressure. Fans will automati-
cally run at the speed corresponding to this pressure according to the change in the load.
Changing air flow
The booster function is accessed when the bottom left icon is selected; a time period (from minimum 1 minute to maximum 4 hours)
can be selected, in which the unit can run at the maximum power. The booster function has the priority over any other fan speed
control method.
After you select the function, a digital chronometer is displayed (hours.minutes.seconds), which is preset on a 10 minute value. This
value can be changed by means of the arrow keys on the right side of the screen: up to increase the booster time and down to reduce
that time. After selecting the desired time, press OK to start the functionality: the display shows the remaining time to the end of the
procedure. When the 00.00.00 value is reached, fans return to be controlled in the previously selected way. When you want to stop the
procedure, just repeat the booster setting operations and select a 0-minute time and press OK.
