•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 5, on page 4. 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, and will only run if there is a heating or cooling demand in Unoccupied periods.
•OVERRIDE — As explained on page 3, pressing the Override button during a programmed, Unoccupied period will force the thermostat into Occupied 1, tem- porarily, up to 4 hours. If the Override button is pressed during an Occupied period, the thermostat will be forced into Unoccupied and the occupied num- ber (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 Over- ride ends.
•HEAT — First Stage = Heat Pump. Second Stage = Heat Pump and Electric Heat.
•FAN PURGE TIMER — When this feature is activated, the fan will turn on during Unoccupied at a preset amount of time prior to Occupied 1. This preoccu- pancy fan purge timer may be set as instructed on page 4, Step 12, 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 disabled. To disable, or ‘lock’ the keypad, press and hold in the Mode button. While holding the Mode button in,
simultaneously press the Up and Down buttons. The Locked icon will appear on the display.

To unlock the buttons, again press and hold the Mode button. While holding the Mode button in, simulta- neously press the Up and Down buttons in together. The Locked icon will disappear from the display.
•DRY CONTACT SWITCH — The terminals are ‘nor- mally 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 1 or more thermostats into Occupied 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 ther- mostat is forced into Occupied 1 via the Dry Contact closure, the icon Occupied 1 will blink.

•HOLIDAY MODE — This feature forces the thermostat into Unoccupied for a preset duration, up to 99 days. The Holiday setup display is entered as follows:
1
HOLIDAY
2
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 imme- diately, enter the Holiday setup screen and select 0.
•SOFT START — This feature is utilized in multiple thermostat installations controlled by the Dry Contact terminals. Assigning a unique Soft Start number 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
