The thermostat uses 24 VAC power
supplied by the system for normal
operation. The electrolytic capacitor
allows you the added convenience of
programming the thermostat even
when not attached to the wallplate,
Attach the thermostat to the
wallplate and allow the capacitor to
charge for at least one hour. After
the capacitor is charged you will
have approximately one hour after
removing the thermostat from the
wallplate to configure and program
the thermostat.

On installation, or when power is
restored after a total power loss to
the thermostat, your thermostat will
automatically maintain a heating
temperature of 62°F (16°C) and a
cooling temperature of 85°F (29°C).
If the 24 volts from the Heating/
Cooling transformer is lost, your
thermostat will lose its display in 2
minutes and may lose time in about
5 hours. This hold up time will be
much shorter if the control had not
been powered for at least 4 hours
prior to the power outage. When
power is restored, the thermostat
will return to the temperatures listed
above.
