* The THP9045A1023 Wire Saver Module is used on heat/cool systems when you only have four wires at the thermostat and you need a fifth wire for a common wire. Use the K terminal in place of the Y and G terminals on conventional or heat pump systems to provide control of the fan and the compressor through a single wire—the unused wire then becomes your common wire. See THP9045 instructions for more information.

** Ventilation is not available on all models. When the U slider is in the down position (2 wires), the U contacts are a dry set of contacts. If your ventilation system requires 24 volts, move the U slider to the up position (1 wire). Lower U terminal is internally jumped to the Rc terminal. In this application, you would hook up one wire from your damper to the upper U terminal and the other to the common side of the transformer.

Setting Slider Tabs

Set R Slider Tab, see Figure 9.

  • Use built-in jumper (R Slider Tab) to differentiate between one or two transformer systems.
  • If there is only one R wire, and it is connected to the R, Rc, or RH terminal on the old thermostat, set the slider to the up position (1 wire).
  • If there is one wire connected to the R terminal and one wire connected to the Rc terminal, set the slider to the down position (2 wires).

Set R Slider Tab

Set U Slider Tab, see Figure 10.

  • Use built-in jumper (U Slider Tab) of universal relay to wire ventilation. Please note that ventilation is not supported on all models.
  • When the U Slider Tab is in the down position (2 wires) the U contacts are a dry set of contacts.
  • If the ventilator is powered by the cooling transformer, move the jumper switch to the up position (1 wire). With this switch set to 1 wire, the lower U terminal is internally jumped to the Rc terminal. In this application, hook up one wire from the vent damper to the U terminal and the other to the common side of the cooling system transformer.

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 Differentials the minimum number of degrees allowed between the heat and cool setpoints when the thermostatis 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 thermostatis 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 thermostats 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 increments) 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 wil tum 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 temperature 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

Lockout Ventilation during "Sleep" program periods. Note: This option is set by the user on the Ventilation screen in the Menu.
ASHRAE is Priority: ASHRAE requires additional ventilation following a long off cycle. The thermostat meets the ASHRAE ventilation standard by running additional ventilation when outdoor conditions are favorable, If ASHRAE cannot be met when outdoor conditions are favorable, the thermostat will override the outdoor lockouts and run ventilation. When using this option, it is recommended that you increase the rate (CFM) of the ventilation equipment to meet the ASHRAE ventilation standard in a shorter run time. The ability to lockout ventilation during the "Sleep" is not an option when you select ASHRAE is Priority.
