Overriding the Daily Schedule
Pressing and holding the FAN button for 5 seconds may be used to interrupt the normal time schedule programming of the thermostat. The override feature may only be used when the thermostat is running the time schedule, in Program On mode.
Unoccupied Operation - During programmed, unoccupied periods pressing and holding the FAN button for 5 seconds will temporarily force the thermostat into Occupied 1 comfort settings for one to six hours (step #14, page 18). The Override icon will be illuminated during this time. If you press and hold the FAN button while the thermostat is currently overriding the daily schedule, this will reset the timer, returning the thermostat to the correct time period program for the day.
Occupied Operation - Pressing and holding the FAN button for 5 seconds during a programmed Occupied time period will have no eect.

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 #9, page 16). 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 #9, page 16), plus the 2nd stage dead-band. This 2nd stage deadband is xed 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 #9, page 16), plus the 2nd stage deadband, plus the 3rd stage deadband. This 3rd stage deadband is xed at one degree and is not
adjustable.
The above gure 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 #15 and 16, page 18-19).
When the CK1 and R terminals are shorted together, and the thermostat is programmed for Unoccupied operation (step #16, page 19), 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 eect.
Important Note: For control of multiple thermostats by one source, refer to ‘Potential Phasing Problems’ on page 31.
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 dierent modes:
Fan: When only the fan icon is displayed this indicates that (1) the fan is in
the Auto mode, (2) the fan will only energize during a heating or cooling cycle, and (3) the fan will modulate fan speeds based on temperature demand.
Fan
, Fan , or Fan : Pressing the FAN button will cause the low, medium, or high speed fan icon to appear (see page 8), indicating that the fan will run continuously. The fan will de-energize if the thermostat is placed in the O mode or a dry contact forced unoccupied time period (see page 23).
Notes:
1) If a Duct sensor is connected to this thermostat, then the fan should be programmed for continuous operation (step #7, page 16). This will provide airow over the Duct sensor and provide more accurate temperature readings.
2) If the fan is programmed for continuous operation (step #7, page 16), 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 O mode.
MINIMAL DISPLAY - When the thermostat is programmed for a minimal display (step #3, page 15), a blank screen will appear. When a button is pressed the full, normal display will appear for 10 seconds.
About Advanced Features & Operation
26
ENERGY SAVING SMART FAN - This feature automatically de-energizes
the fan during an Unoccupied time period, except when necessary to heat or cool.
Note: The fan will not de-energize during an Unoccupied time period if it has been programmed for continuous operation (step #7, page 16).
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 #10, on page 17. This minimum dierence 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 and adjust to the desired setpoint. Press the MODE button until only the cool setpoint is displayed and 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 EC0402) - The thermostat
is programmed from the factory to automatically recognize when a Duct Sensor is connected (page 17).
The Duct Sensor measures indoor air temperature and sends this information to the thermostat. It measures temperature with a range of 32˚to 99˚F.
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.

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 #9, page 16). 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
When using the auxiliary input (CK1 & R) or controlling multiple HVAC units with a 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.
