UWP Mounting System installation

1. Open package to find the UWP. See Figure 1.
2. Position the UWP on the wall. Level and mark hole positions. See Figure 2. Drill holes at marked positions, and then lightly tap supplied wall anchors into wall using a hammer. ‒ If your box contains red anchors, drill 7/32” (5.6 mm) holes for drywall. If your box contains yellow anchors, drill 3/16” (4.8 mm) holes for drywall.
3. Pull the door open and insert wires through wiring hole of the UWP. See Figure 3.
4. Place the UWP over the wall anchors. Insert and tighten mounting screws supplied with the UWP. Do not overtighten. Tighten until the UWP no longer moves. Close the door. See Figure 4.

Optional Decorative Cover Plate installation

Use the Optional Cover Plate when you need to cover paint gap from the old thermostat. There are different cover plates depending on when the thermostat was manufactured. One plate is square, the other is rectangular.

1. Separate the cover plate from the mounting plate. See Figure 1.
2. Mount the mounting plate to the wall using any of the screw holes. Insert and tighten mounting screws supplied with the cover plate. Do not overtighten. Make sure the mounting plate is level. See Figure 2a (square) or 2b (rectangle).
3. Attach the UWP by hanging it on the top hook of the mounting plate and then snapping the bottom of the UWP in place. See Figure 3.
4. Snap the Cover Plate onto the mounting plate. See Figure 4.
   If there are no existing wall anchors, you can follow the same instructions for the UWP Mounting System installation to install the cover plate. Just use 2 screws rather than 3.

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.

• 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.

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 U Slider Tab, see Figure 10.

• 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.

Wiring

NOTES:

1. Available wiring configurations differ by product models/product numbers.
2. Use 18- to 22- gauge thermostat wire. Shielded cable is not required.
3. Set the R Slider Tab on the UWP to the up position (1 wire) for 1 transformer systems or the down position (2 wires) for 2 transformer systems. See “Setting Slider Tabs” on page 4.
4. Set the U Slider Tab to the up position (1 wire) for non-powered ventilation or the down position (2 wires) for powered ventilation. See “Setting Slider Tabs” on page.

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.
