* The THP9045A1098 C-wire adaptor 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.
Wiring UWP
Push down on the tabs to put the wires into the inner holes of their corresponding terminals
on the UWP (one wire per terminal) until they are firmly in place. Gently tug on the wires to
verify they are secure. If you need to release the wires again, push down the terminal tabs
on the sides of the UWP.
This wiring is just an example,
yours may vary.

Setting Slider Tabs
Set R Slider Tab, see Figure 1.
• 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 U Slider Tab, see Figure 2.
• Use built-in jumper (U Slider Tab) of
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.

1000 Vent Type None, ERV/HRV, Passive, Fresh Air Damper None: The thermostat does not control ventilation.
ERV/HRV: The thermostat controls an Energy Recovery Ventilator or Heat Recovery Ventilator for ventila- tion. Passive (Fan Only): The thermostat turns on the fan for ventilation. When set to passive fan, the thermo- stat does not control a damper or ventilator. The passive ventilation/passive fan setting only runs the indoor blower fan. This setting does not open a damper or run a ventilator. To use this setting for ventilation, the home would need to be set-up with a pipe from outdoors into the return duct that is either permanently open or has a damper that automatically opens whenever the blower fan is on. Note: Some models only offer the passive fan setting.
1005 Vent Method ASHRAE 2010, ASHRAE 2013, Percent On Time Note: Options of this ISU may vary depending on the model of the thermostat. 1006 Vent Fan Control Thermostat, Equipment Thermostat: The thermostat turns on the ventilation and the fan when ventilation is needed.
Equipment: Ventilation equipment controls the blower fan.
1007 Bedrooms 1 - 6 (2) This ISU is only displayed when ISU 1005 Ventilation Method is set to ASHRAE 2010 or 2013. 1008 Home Size 1000 Sq. Ft. - 5000 Sq. Ft. (1000 Sq. Ft.) This ISU is only displayed when ISU 1005 Ventilation Method is set to ASHRAE 2010 or 2013. 1009 Vent Rate 30CFM - 350CFM (in 5CFM increments) (150CFM) This ISU is only displayed when ISU 1005 Ventilation Method is set to ASHRAE 2010 or 2013. 1011 Vent Percent On Time 10% - 100% (30%) The thermostat operates ventilation equipment based on a percentage entered in the installer setup (ISU
1012). For example, if Percent on Time is set to 50%, the ventilation equipment will run at random times dur- ing a 1 hour period until it reaches a 50% run time (approximately 30 minutes). This ISU is only displayed if ISU 1005 is set to Percent On Time.
1012 Vent Priority Lockouts, ASHRAE Lockouts are Priority: The thermostat places a priority on lockouts versus the ASHRAE ventilation
standard. The thermostat will not run ventilation during the following lockout conditions (if configured), unless you manually call for ventilation: Lockout Ventilation during Outdoor Conditions (ISU 1013, 1014 and 1015). 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 favor- able. 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.
