About Advanced Features & Operation2 STAGE OPERATION - The 2nd Stage of heat or cool isturned on when (1) the 1st Stage has been on for aminimum of two minutes, and (2) the temperature spreadfrom the setpoint is equal to or greater than: the setpointplus the deadband, plus 2 degrees.CoolingHeating2 degrees2nd Stageturn on1st Stageturn onDeadBandHeatSetpointDeadBandCoolSetpoint2 degrees1st Stageturn on2nd Stageturn onMINIMUM HEAT/COOL SETPOINT DIFFERENCE - The Heatand Cool setpoints will not be allowed to come any closerto each other than the value set in Advanced Setup step# 7, on page 13. This minimum difference is enforcedduring Auto changeover and Program On operation.Page 16
About Advanced Features & OperationEMERGENCY HEAT - Is a feature available to Heat Pumpinstallations. To turn on Emergency Heat press in theFan button. While holding the Fan button pressthe Up button for 2 seconds. The Cool setpoint displaywill read ‘EH’.I2:0073SuPress forEmergency Heateh74FanDuring Emergency Heat the thermostat will turnon the fan and the 2nd stage of heat, when there is ademand for heat, locking out the 1st stage compressor.Exiting Emergency Heat is the same as entering. DuringEmergency Heat only OFF and HEAT are available.ELECTRIC HEAT - Selecting Electric Heat on, page 13,step 5, will cause the thermostat to turn on the fanimmediately any time there is a heat demand. Since allgas furnaces control the fan, this feature should be offunless the heater is only electric.Page 17

About Advanced Features & OperationDUAL SETPOINT BEHAVIOR - The adjustable setpoint rangeis: 35 - 99 degrees in Fahrenheit and 7 - 35 degrees inCentigrade. When in the modes Heat or Cool, thisadjustable range is unhampered.When adjusting any Auto mode, including programmingOccupied and Unoccupied periods, the 1050 will notallow the Heat setpoint to get closer to the Cool setpointthan the value programmed as the minimum difference instep 7, page 13.When entering the Auto mode from Cool, the Heat andCool setpoints will remain spread apart by the amountthat they were adjusted, prior to entering Auto.For example: If the Cool setpoint was set to 80 whilein the Cool mode and the Heat setpoint was adjusted to70 while in the Heat mode, upon entering the Auto modethe Heat and Cool setpoints would be 80 and 70. Bothsetpoints would then move up and down together, (in thisexample spread by 10 degrees), by pressing the up ordown buttons.To move the Heat and Cool setpoints closer together,enter the Cool or Heat mode by pressing the Mode button,then adjust the setpoint(s) closer together. Heat is limitedto how close it can come to Cool by step 7, page 13.Page 19
