Orbit 83521 - Advanced System Setup; Temperature Offset

32 33
EARLYSTARTFUNCTIONALITY THERMOSTATCARE
This function allows the heating or cooling system
to turn on before the programmed start time
so that the room temperature matches the set
temperature at the start time.
Example:
Your Wake time is set for 6:30 am with a
temperature of 72°. Your system will turn on before 6:30
am, so the temperature is 72° when you wake up.
Note: To turn on this function see page 17.
To prevent damage to the clear lens over the
thermostat face, use a so coon cloth and
clean with mild soap and water only.
DO NOT use paper towels or other abrasive
cloths. DO NOT spray any liquid directly
onto the thermostat.
It is recommended that the baeries
in the thermostat be replaced once
a year or before leaving the home for
a prolonged period of time.
1. Switch the system MODE to off before
changing the baeries.
2. Remove the thermostat body from its
base by gently pulling them apart.
3. Turn the thermostat over and remove
old baeries.
4. Replace them with fresh Energizer
®
or Duracell
®
alkaline AAA baeries,
carefully observing the required
polarities.
5. Reinstall the thermostat body onto its
base by gently pushing it until it “clicks”
into place.
Note: If the batteries are not changed within 7
days after the Low Battery Indicator appears
on the display, the set temperature will
increase by 10°F in cool mode, or decrease by
10°F in heat mode as a further reminder. After
90 days, or less, depending on the condition of
the batteries, the system will turn off and the
Low Battery Indicator will flash on the display.
WARNING: Failure to change
batteries in a timely fashion can lead
to uncontrolled heating and cooling.
