CONSUMABLES
Consumables are parts of your HVAC system that get used up; like filters and
UV bulbs. The
LS-90 keeps track of system run times and can be programmed to remind you when
consumables, such as air filters, humidifier pads and UV bulbs, should be checked and/or changed.
(HUM PAD = Run time of humidifier, AIR FILTER = Run time of HEAT+COOL, UV BULB = Real time)
To set/adjust CHECK CONSUMABLES ALERTS:

2.Touch the number of weeks in the CHECK ALERT column for
that item, and use the +/- buttons to raise or lower the setting.
- Alerts may be scheduled from 0 to 99 weeks.
3. Repeat for each item included in your system.
- If your system does not include a listed item, leave the
CHECK ALERT at 00wks.
4.Press HOME to return to the Home screen.
When the Run Time for a given item reaches the limit you have
set, the
LS-90 will show you a reminder in the message area of
the Home screen.
