Programming

Occupied & Unoccupied Periods

PROGRAMMING NOTES You will be prompted to enter both heat and cool setpoints even if the thermostat is configured for heat only, or cool only.

• If only Occupied 1 is selected, the Occupied 2 & 3 steps will be skipped. Further, if only 2 occupieds are selected, the Occupied 3 steps will be skipped. • Heat & Cool setpoints for Occupied 1 are the same for each day. Heat & Cool setpoints for Occupied 2 & 3 can be adjusted differently for each day, if desired. • 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. • The Unoccupied settings take effect at all times when: (1) the program is on and (2) the current time is outside a preset occupied period. For this reason start and stop times aren’t necessary for unoccupied. • If the same start and stop times are programmed in for an occupied period, then it will run 24 hours. • If one occupied period starts and stops within another occupied period, 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. • When the time period programming for Unoccupied is in the Override mode (see page 9), the Heat & Cool setpoints for Occupied 1 are used.

About Advanced Features & Operation 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 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 #9, page 16), plus the 2nd stage deadband, plus the 3rd stage deadband. This 3rd stage deadband is fixed at one degree and is not adjustable. Heating 1˚ 1˚ 1˚-6˚ DB3 DB2 DB1

About Advanced Features & Operation 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 effect. Important Note: For control of multiple thermostats by one source, refer to ‘Potential Phasing Problems’ on page 31.

About Advanced Features & Operation FAN OPERATION - Fan operation is available in four different 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 Off 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 airflow 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 Off 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.

25

About Advanced Features & Operation 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 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 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 Digital Sensor is programmed from the factory to automatically High Temp. Heat Shrink Tubing recognize when a Duct Sensor is connected (page 17). Plenum Rated The Duct Sensor measures indoor air temperature Cable and sends this information to the thermostat. It measures temperature with a range of 32˚to 99˚F. White Black 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.

28

About Advanced Features & Operation SINGLE SETPOINT BEHAVIOR - When configured for Single Setpoint operation (step #4, page 16), 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 #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.

Sample Wiring Diagram Auxiliary Input Control and Multiple HVAC Control Potential Phasing Problems CAUTION WARNING 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. Diagram A- Auxiliary Control CK 1 110vac
