# ISU ISU Name ISU Options (defaults in bold) Notes 256 EM Heat Type Electric, Gas/Oil (or Fossil Forced Air) This ISU is displayed only if ISU 200 is set to Heat Pump AND if ISU 221 Aux/E heat stages = 1 AND if ISU 253
is set to run AUX/E heat separately. Note: This ISU may not be available at all on some models.
260 Fossil Kit Control Thermostat, External (Fossil Fuel Kit Controls Backup
Heat)
This ISU is displayed only if ISU 200 is set to Heat Pump AND if ISU 221 Aux/E heat stages = 1, AND if ISU 256 is set to Gas/Oil. Note: This ISU may not be available at all on some models.
300 Auto Changeover On, Off OFF: The user must select heating or cooling as needed to maintain the desired
indoor temperature. ON (Automatic): On (enabled) Allows user to select Auto Changeover as one of the system modes from the home screen. In auto mode, the thermostat can control either heating or cooling to maintain the desired indoor temperature.
303 Auto Differential 0 °F to 5 °F or 0.0 °C to 2.5 °C Differential is the minimum number of degrees allowed between the heat and cool setpoints when the thermo-
stat is in auto-changeover. Differential is NOT deadband. The deadband temperature between when heating (or cooling) cycles on and cycles off to maintain setpoint is not adjustable. Honeywell uses an algorithm that fixes deadband at 0 °F. This algorithm is more advanced than on previous thermostats.
305 High Cool Stage
Finish
Yes, No This ISU is only displayed when the thermostat is set to 2 cool stages. When set to YES, this feature keeps the
higher stage of the cooling equipment running until the desired setpoint is reached.
306 High Heat Stage
Finish
Yes, No This ISU is only displayed when the thermostat is set to 2 or more heat stages. When set to YES, this feature
keeps the higher stage of the heating equipment running until the desired setpoint is reached.
340 Aux Heat Droop 0 = Comfort; 2 °F to 15 °F from setpoint (in 1 °F incre-
ments) or 1.0 °C to 7.5 °C from setpoint (in 0.5 °C increments)
Aux heat droop can be set on heat pump systems with an auxiliary heat stage. The Comfort setting is NOT available for Dual Fuel systems. Default setting is 0 °F (Comfort) for Electric while 2 °F for Gas/Oil. The indoor temperature must drop to the selected droop setting before the thermostat will turn Aux Heat on. For example, if Aux Heat is set to 2 °F (1.0 °C), the indoor temperature must be 2 ° F (1.0 ° C) away from the setpoint before Aux Heat turns on. When set to Comfort, the thermostat will use Aux Heat as needed to keep the indoor tem- perature within 1 °F (0.5 ° C) degree of the setpoint.
350 Up Stage Timer Aux
Heat
Off, 30, 45, 60, 75, 90 minutes 2, 3, 4, 5, 6, 8, 10, 12, 14, 16 hours
The Auxiliary Heat Upstage Timer starts when the highest stage of the previous heating equipment type turns on. Auxiliary heat will be used (if needed) when the timer expires. This ISU is only displayed when ISU 340 (AUX Heat Droop) is set to 2 °F or higher.
355 Balance Point
(Compressor Lockout)
Off, 5 °F to 60 °F (in 5 °F increments) or 15.0 °C to 15.5 °C (in 2.5 °C or 3.0 °C increments)
Compressor Lockout requires an outdoor temperature. Set Compressor Lockout to the temperature below which it is inefficient to run the heat pump. When outside temperature is below this setting, thermostat will lockout heat pump and run Aux Heat only. This ISU is only displayed if ISU 130 = Wired or Internet, ISU 200 is set to Heat Pump, ISU 221 Aux/E stages = 1, AND ISU 260 is set to Thermostat. We recommend using a wired remote sensor as an outdoor temperature source. Default is 40 °F if ISU 205 Heating Equipment is Air to Air Heat Pump and ISU 255 Aux Heat Type is Gas/Oil. Default is Off if ISU 205 Heating Equipment is Air to Air Heat Pump and ISU 255 Aux Heat Type is Electric. Default is Off if ISU 205 Heating Equipment is Geothermal. Compressor Lockout is optional for any type of heat pump (Air to Air Heat Pump, Geothermal Heat Pump).
