W
hat The Master Scheduler Can Do For You:
For one thing, it can take a load off your mind.
Once you've set a schedule on the Master
Scheduler, it will maintain comfort control for
you. Energy efficiency and lower utility bills are
now the Master Scheduler's job, not yours. The
thermostat will adjust when it's supposed to, and it
won't forget, as a mere mortal might.
It will remember what you tell it, even during
emergencies. You'll be happy to know that –
unlike your VCR and other electronic digital clocks
– the Master Scheduler won't forget its
setpoints during a power failure. You have
plenty of other things to worry about when that
happens. You probably won't find the instruction
manual by then anyway, so that's why we've factory
installed three button batteries for power backup.
Simply activate them and don't worry about a
power failure knocking out your Master Scheduler
thermostat.
When the LCD clock flashes, it's time to
replace your batteries.* But even when you have to
change your batteries, your Master Scheduler
won't forget it's schedule.
*Of course, the hours, minutes and day indicators will flash when we
5
are setting the clock (even when the batteries are OK).
The Master Scheduler will stay in touch with
you and your Integrated Zone TM System. A little
green light will flash to let you know it's talking
with the heat pump or air conditioner. That's good.
The last thing you want is a senseless sensor.
