Page 25: About Advanced Features & Operation
About Advanced Features & Operation CALIBRATION - Under normal circumstances it will not be necessary to adjust the calibration of the temperature sensor. If calibration is required, please contact a trained HVAC technician to correctly perform the following procedure. I2:00 MODE Place the thermostat in the OFF mode.
Page 26 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 #8, page 20).
Page 27 About Advanced Features & Operation DRY CONTACT SWITCH - This feature allows an external device such as a Central Time Clock, Occu- pancy Sensor, or a Telephone activated device to force one or more thermostats into Occupied 1 or Unoccup- ied (steps #14 and 15, page 21-22).
Page 28 Dry Contact use note of caution 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.
Page 29 About Advanced Features & Operation FACTORY DEFAULTS - If, for any reason, you desire to return all the stored settings back to the factory default settings, follow the instructions below. WARNING: This will reset all Time Period and Ad- vanced Programming to the default settings. Any information entered prior to this reset will be permanently lost.
Page 30 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 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).
Page 31 About Advanced Features & Operation ENERGY SAVING SMART FAN - This feature auto- matically de-energizes the fan during an Unoccupied time period, except when necessary to heat or cool (see page 28). I2:00 unoccupied Note: The fan will not de-energize during an Un- occupied time period if it has been programmed for continuous operation (step #7, page 20).
Page 32 About Advanced Features & Operation KEYPAD LOCKOUT - To prevent unauthorized use of the thermostat, the front panel buttons may be disabled. To disable, or ‘lock’ the keypad, press and hold the MODE button. While holding the MODE button, press the UP and DOWN buttons together.
Page 33 About Advanced Features & Operation OUTSIDE SENSOR - To view an Outside Sensor (step #12, page 21), enter the Advanced Setup by pressing and holding the MODE button. While holding MODE, press the FAN button for 5 seconds to enter Setup screens. Advance to setup step #12 by repeatedly pressing the MODE button.
Page 34 About Advanced Features & Operation SINGLE SETPOINT BEHAVIOR - When configured for Single Setpoint operation (step #4, page 19), the degree icon will blink when the large number is display- ing room temperature and will remain solid when dis- playing the heating or cooling setpoint. In the Auto and Program On modes the deadband is enforced both above and below the setpoint.
