• CLOCK BACKUP -- In the event of a power loss,
the thermostat internal clock will continue to keep
proper time for a minimum of 48 hours without
external power or batteries.
• MINIMUM HEAT/COOL SET POINT DIFFERENCE
-- The Heat and Cool set points will not be allowed
to come any closer to each other than the value set
in Advanced Setup Step 6, on page 4. This mini-
mum difference is enforced during Auto changeover
and Program On operation.
• ENERGY SAVING SMART FAN -- If Fan On is
selected, the fan will run continuously at all times. If
fan is in Off Mode it will only run if there is a heating
or cooling demand during programmed unoccupied
periods.
• OVERRIDE -- As explained on page 2, pressing
the Override button during a programmed, Unoccu-
pied period will force the thermostat into Occupied
1, temporarily, up to 4 hours. If the Override button
is pressed during an Occupied period, the thermo-
stat will be forced into Unoccupied and the occu-
pied period (1,2 or 3), it was forced out of will be
turned off, only for that day.
• During Override periods the set points may be
adjusted, but they will not be remembered after
Override ends.
• FAN PURGE TIMER -- When this feature is acti-
vated, the fan will turn on during Unoccupied at a
preset amount of time prior to Occupied 1. This pre-
occupancy fan purge timer may be set as instructed
on this page, Step 13,from 0 to 3 hours. 0 = this
feature turned off.
• KEYPAD LOCK -- To prevent unauthorized use of
the thermostat, the front panel buttons may be dis-
abled. To disable, or 'lock' the keypad, press and
hold the Mode button. While holding the Mode but-
ton, simultaneously press the Up and Down but-
tons. Locked will appear on the display.
Press all 3 for _) Locked
Keypad Lockout _ "--_
To unlockthe buttons, again press and hold the
Mode button. While holding the Mode button, simul-
taneously press the Up and Down buttons. Locked
will disappear from the display.
DRY CONTACT SWITCH -- The terminals are
'normally open'. Closing or completing the circuit
will cause the thermostat to enter Occupied 1. This
feature allows an external device such as a central
time clock, occupancy sensor, or a telephone-
activated device to force one or more thermostats
into Occupied 1. For the Dry Contact to work the
thermostat must be in Program On. Set Occupied
1 to Offforall 7days, so the Contact closure will be
in control. When the thermostat is forced into Occu-
pied 1 via the Dry Contact closure, the icon
Occupied 1 will blink.
