If the start time is set for later than the stop time, the program will run from the start time to midnight and from midnight to the stop time on the same day. For example: 9:00pm start, 8:00am stop, on MTWTF. This program will run from 12:00am MTWTF to 8:00am MTWTF and again from 9:00pm MTWTF to 12:00pm MTWTF.

TheUnoccupiedsettingstakeeffectatalltimeswhen:(1)theprogramis on and (2) the current time is outside a preset occupied period. For this reason start and stop times arent necessary for unoccupied.

Ifthesame start and stop times are programmed in for an occupied period, then it will run 24 hours.

Ifoneoccupiedperiodstartsandstopswithinanotheroccupiedperiod,the lower occupied # has priority. For example: If Occupied 3 is programmed to be on 24 hours, and Occupied 2 is programmed to run that day, then Occupied 2 settings will take over from Occupied 3 between Occupied 2 start and stop times.

DEADBAND OPERATION - Controls one Heat and one Cool stage with a three speed fan (see below).

The low speed fan for heat or cool is turned on when: The temperature spread from the setpoint is equal to or greater than: the setpoint plus the 1st stage dead-band (step #8, page 20). This 1st stage deadband is adjustable from 1-6 degrees and the default is two degrees.

The medium speed fan for heat or cool is turned on when: The temperature spread from the setpoint is equal to or greater than: the setpoint plus the 1st stage deadband (step #8, page 20), plus the 2nd stage dead-band. This 2nd stage deadband is fixed at one degree and is not adjustable.

The high speed fan for heat or cool is turned on when: The temperature spread from the setpoint is equal to or greater than: the setpoint plus the 1st stage deadband (step #8, page 20), plus the 2nd stage deadband, plus the 3rd stage deadband. This 3rd stage deadband is fixed at one degree and is not adjustable.

The above figure assumes the minimum on time for the prior stage has been met to allow the next stage to turn on, once the deadbands have been exceeded.

DRY CONTACT SWITCH - 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 an Unoccupied mode (steps #14 and 15, page 21-22).

When the CK1 and R terminals are shorted together, and the thermostat is programmed for Unoccupied operation (step #15, page 22), the thermostat will be forced into Unoccupied setpoints and the Unoccupied icon will appear on the display.

Note: The thermostat must be in Program On mode for this feature to have any effect. Important Note: For control of multiple thermostats by one source, refer to Potential Phasing Problems on page 32.

Connect wires to a time clock or other device to force the thermostat into Occupied 1 or Unoccupied.

FAN OPERATION - Fan operation is available in four different modes:

Fan: When only the fan icon is displayed, this indicates that the fan is in the Auto mode, will only energize during a heating or cooling cycle, and will modulate fan speeds based on temperature demand (see page 25).

Fan , Fan , or Fan : Pressing the FAN button will cause the low, medium, or high speed fan icon to appear (see page 11), indicating that the fan will run continuously. The fan will de-energize if the thermostat is placed in the Off mode or a dry contact forced unoccupied time period (see page 26).

Notes: 1) If a Duct sensor is connected to this thermostat, then the fan should be programmed for continuous operation (step #7, page 20). This will provide airflow over the Duct sensor and provide more accurate temperature readings.

2) If the fan is programmed for continuous operation (step #7, page 20), the low speed fan will run continuously when the fan is in the Auto mode, but will de-energize if the thermostat is placed in the Off mode.

MINIMAL DISPLAY - When the thermostat is programmed for a minimal display (step #3, page 18), a blank screen will appear. When a button is pressed the full, normal display will appear for 10 seconds.

About Advanced Features & Operation

29

ENERGY SAVING SMART FAN - This feature automatically de-energizes the fan during an Unoccupied time period, except when necessary to heat or cool (see page 28).

Note: The fan will not de-energize during an Unoccupied time period if it has been programmed for continuous operation (step #7, page 20).

HEAT/COOL DIFFERENTIAL - The Heat and Cool setpoints will not be allowed to come any closer to each other than the value set in Advanced Setup step #9, on page 20. This minimum difference is enforced during Auto-changeover and Program On operation.

Note: To increase the spread between the heating and cooling setpoints in the Auto-changeover mode press the MODE button until only the heat setpoint is displayed; adjust to the desired setpoint. Press the MODE button until only the cool setpoint is displayed; adjust to the desired setpoint. Press the MODE button again to enter the Auto-changeover mode where both the heat and cool setpoints are displayed.

DUCT SENSOR (P/N G100-71308305) - The thermostat is programmed from the factory to automatically recognize when a Duct Sensor is connected (step #12, page 21).

The Duct Sensor measures indoor air temperature and sends this information to the thermostat; it measures temperature with a range of 32to 99F.

IMPORTANT: Do not use shielded wire. Do not run sensor wiring in the same conduit as the 24VAC thermostat wiring. Electrical interference may cause the sensor to give incorrect temperature readings.

See the Duct Sensor instructions for further details.

SINGLE SETPOINT BEHAVIOR - When configured for Single Setpoint operation (step #4, page 19), the degree icon will blink when the large number is displaying room temperature and will remain solid when displaying the heating or cooling setpoint. In the Auto mode the deadband is enforced both above and below the setpoint. To avoid short cycling, a deadband of at least two degrees is recommended (step #8, page 20). To display the room temperature press and hold the MODE button for two seconds. Release the MODE button to return to the normal display.

Auxiliary Input Control and Multiple HVAC Control Potential Phasing Problems

Whenusingtheauxiliaryinput(CK1&R)orcontrollingmultipleHVACunitswitha single thermostat, it is possible to encounter transformer phasing problems that will interfere with thermostat operation. Connecting transformers that are not phased correctly may result in a direct short, which could damage transformers and/or the thermostat. Phasing problems are likely if the units share a common ground with secondary grounded transformers. SOLUTION: If possible, phase all HVAC units together. If phasing is impractical, isolation relays may be used to isolate the transformers. To isolate the auxiliary input, use a separate transformer for the auxiliary control device, usually a time clock. Connect the device to an isolation relay coil. Connect one set of isolated contacts to each thermostat at CK1 and R. See diagram A. Diagram A- Auxiliary Control
