• 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 2
. This minimum
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,
except in Off mode, and will only run if there is a
heating or cooling demand.
• OVERRIDE — Press the Override button during a
programmed, unoccupied period to force the thermo-
stat into the Occupied 1 period, temporarily, up to
4 hours. If the Override button is pressed during an
Occupied period, the thermostat will be forced into
Unoccupied and the occupied 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 adjust-
ed, but they will not be remembered after Override
ends.
• FAN PURGE TIMER — When this feature is activated,
the fan will turn on during the Unoccupied period at a
preset amount of time prior to the Occupied 1 period.
This preoccupancy fan purge timer may be set as
instructed in
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 button,
simultaneously press the Up and Down buttons.
Locked
will appear on the display.
To
unlock
the 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 fea-
ture allows an external device such as a central time
clock, occupancy sensor, or a telephone-activated
device to force one or more thermostats into Occu-
pied 1. For the dry contact to work the thermostat
must be in
Program On
.
Set Occupied 1 to Off for all
7 days,
so the Contact closure will be in control.
When the thermostat is forced into Occupied 1 via
the dry contact closure, the icon
Occupied 1
will blink.
