HOLIDAY MODE -- This feature forces the thermo-
stat into Unoccupied for a preset duration, up to
99 days, The Holiday setup display is entered as
follows:

Press the Up or Down buttons to select the
".......... -' number of days the thermostat will be in
_: ) Holiday mode. 0 = Off. To exit Holiday setup,
press the Mode button.
The thermostat will enter the Holiday mode when
the clock crosses midnight.
During Holiday mode Unoccupied set points are
enforced.
The Override button is active during Holiday mode.
It will override to Occupied 1 settings up to 4 hours
then return to Holiday mode. The Dry Contact
Switch is ignored.
The thermostat will exit Holiday mode at midnight of
the final programmed day. To terminate Holiday
immediately, enter the Holiday setup screen and
select 0.
SOFT START -- This feature is utilized in multiple
thermostat installations controlled by the Dry Con-
tact terminals. Assigning a unique Soft Start num-
ber to each thermostat will stagger the turn on
times, even though the Dry Contact closes, for all
the thermostats connected, at the same time. Each
Soft Start number represents a multiple of 30 sec-
onds from the Dry Contact closure. For example,
no. 1 = turn on 30 seconds after Dry Contact clo-
sure, no. 2 = turn on 60 seconds after closure,
no. 3 = turn on 90 seconds after closure, and so on.
See page 5, Step 13, to configure the thermostat for
Soft Start.
DUAL SET POINT BEHAVIOR --The adjustable
set point range is: 35 to 99 degrees in Fahrenheit
and 7 to 35 degrees in Celsius. When in the modes
Heat or Cool, this adjustable range is unhampered.
When adjusting any Auto mode, including program-
ming Occupied and Unoccupied periods, the ther-
mostat will not allow the Heat set point to get closer
to the Cool set point than the value programmed as
the minimum difference in Step 5, page 4.
When entering the Auto mode from Cool, the Heat
and Cool set points will remain spread apart by the
amount that they were adjusted, prior to entering
Auto.
For example: If the Cool set point was set to 80
while in the Cool mode and the Heat set point was
adjusted to 70 while in the Heat mode, upon enter-
ing the Auto mode the Heat and Cool set points
would be 80 and 70. Both set point temperatures
would then move up and down together, (in this
example spread by 10 degrees), by pressing the up
or down buttons.
To move the Heat and Cool set point temperatures
closer together, enter the Cool or Heat mode by
pressing the Mode button, then adjust the set point
temperatures closer together. Heat is limited to how
close it can come to Cool by Step 5, page 4.
REMOTE SENSORS (Optional Accessory) --
When connected to terminals RS+5, RS, and GND
on the back of the thermostat, the thermostat will
read the temperature from the Remote Sensor and
ignore the temperature sensor inside the thermo-
stat. The thermostat automatically recognizes when
a Remote Sensor is connected. When reading the
temperature from the remote, the degree icon
above the room temperature blinks once a second.
The Override button
Optiona_
Remote Sensor
Optional Sensor
on the Remote Sensor
works slightly different
than the Override but-
ton on the front panel.
Each press of the
'External' Override but-
ton adds 2 hours to the
override timer, if the
timer was already active, the first button press will
round the runtime to either 2:00 or 4:00.
Subsequent button presses will not wraparound as
the Override button on the thermostat does, so the
second or greater button press will set the runtime
to 4:00. The Locked feature has no effect on the
external Override button. The wired Remote Sensor
is connected to the thermostat with up to 500 ft of
20 ga. or 300 ft of 18 ga. thermostat wire. See the
Remote Sensor instructions for further details.
FACTORY DEFAULTS -- Before restoring factory
defaults, set thermostat to OFF mode. If, for any
reason it is desirable to return all stored settings
back to the factory default settings, press the Mode
button. While holding the Mode button in, press the
Fan button for 5 seconds. All icons will appear.
Press and hold in the Fan button until Fd appears.
This resets all factory settings. To calibrate room
temperature, press the Up and Down buttons at
the same time twice. At this point use the Up and
Down buttons to calibrate room temperature, if
needed. Press the Mode button to return to normal
operation.
