4.4.2 Filter Life Monitor

The IQAir system is equipped with an electronic Filter Life Monitor that calculates the remaining life of the sys tem’s

lters. Thanks to the Filter Life Monitor, the user does not have to guess when lters need to be replaced or replace

them at xed intervals (which rarely correspond to the actual amount of use). The Filter Life Monitor watches over

the most important factors affecting the life of the individual lters. The Filter Life Monitor display shows the

remaining life of each individual lters at any given time.

1. To reach the Filter Life Monitor display from the main display win dow,

press the Menu key once. The remaining life of the filter 1.

will appear.

2. Press the p key to view the remaining life of the next lter in the system.

3. The remaining life of the lters is expressed in hours of operation at the

current speed setting and the programmed lter load indices.

How the Filter Life Monitor Works

The basis for the calculation of the remaining lter life is the already elapsed operation time at the set fan speeds and

lter load indices during that period. This input is compared with an internal memory bank which contains infor -

mation about the different lters’ lives under specic conditions of use.

The Filter Life Monitor makes a calculation of the remaining lter life, taking into account not only past use of the

system, but also likely future use. As reference for future use, the lter life monitor uses the fan speed and the lter

load indices which are programmed at the time.

The relationship between the current fan speed, the current lter load indices and the remaining lter life displayed

can be expressed as follows:

• The higher the current fan speed setting, the shorter the displayed remaining lter life.

• The higher the current lter load index setting, the shorter the remaining lter life displayed for the affected lter.

7. Filter Life Reset

Allows the resetting of the lter life counter after replacing a lter

element.

8. Airow Units

Allows to switch the airow units between cfm (cubic feet per minute)

and m

/h (cubic meters per hour).

9. Language

Allows the modication of the display language.

10. Filter Load Index Setting

Allows the modication of the air pollution index, so the system can

calculate the remaining lter life, taking pollution intensity into account.

11. Service Access

This menu is designed for factory access only.
