Before Getting Started

Before getting started, please review the following pre-installation checklist.

Check package contents

Open the package and verify that the following items are included:

  • Wallplate (A) thermostat (B) white cover (C)
  • 4 color inserts (D)
  • Clear plastic cover (E)
  • 2 mounting screws and wall anchors (F)

  • Installation Instructions and User Guide

EMERSON-White-Rodgers-UP400-Programmable-Thermostat-3

Answer questions about source of heating in your home

  • Do you have either an oil or gas burning furnace?
  • Do you have a Heat Pump (and is it 1-stage or 2-stage)?*
  • Do you have Hydronic Heating (steam or hot water radiators or radiant fl oor heating)?
    To determine if you have a Heat Pump and/or whether it is a 1-stage or 2-stage model, see the Appendix on the last page of the Manual.

Assemble tools

You will need the following tools:

  • Flat-head screwdriver
  •  2 AA alkaline batteries

EMERSON-White-Rodgers-UP400-Programmable-Thermostat-4

You may also need:

  • Hammer
  • Drill with 3/16″ (4 mm) bit
  • Small pliers to bend wires

Turn off power to your heating and cooling system
Typically, this is achieved by flipping a switch on the outside of the furnace/air handler to the “OFF” position.

CAUTION
Do not turn the system back on until you have completed the installation and set up of the thermostat.

Remove Old Thermostat and Install New Thermostat

Tip
Do not disconnect wires from the old thermostat until you label all the wires according to this manual.

Expose wires connected to old thermostat

  1. After turning off power to your heating & cooling system, expose wallplate with wires and wire terminals. The required steps vary depending on your old thermostat type.
    Your old thermostat may consist of:
    • 3 parts: a cover, base and wallplate or
    • 2 parts: a cover and wallplateEMERSON-White-Rodgers-UP400-Programmable-Thermostat-5
    • The Cover: This usually pulls off, but is sometimes secured by a screw which must be loosened.
    • The Base: This either pulls off or needs to be removed by loosening screws under the cover.
    • The Wallplate: This is removed by loosening the screws that hold the thermostat to the wall.
  2. Loosen all screws holding the old thermostat’s wallplate to the wall. Do not disconnect the wires from terminals. Allow the wallplate to hang loosely on the wires.

EMERSON-White-Rodgers-UP400-Programmable-Thermostat-6

Tip

  • Ignore wire colors. There is no standard color code for thermostat wires.
  • Ignore existing wire labels, if they are present.
  • Use the provided labels to label/re-label the thermostat wires.
  • The new labels must remain on the wires at least until the installation process is complete.
  • No two wires can have the same label.

EMERSON-White-Rodgers-UP400-Programmable-Thermostat-7

Label and disconnect the wires

  1. Note you may see two types of wiring in the old thermostat:
    1. Wires leading from the wall to a terminal on the thermostatEMERSON-White-Rodgers-UP400-Programmable-Thermostat-8
    2. Wires connecting one terminal to another (jumper wire).EMERSON-White-Rodgers-UP400-Programmable-Thermostat-9
      These don’t have to be labeled.
  2. Label each wire that comes out of the wall and attaches to terminals on the old thermostat. Use labels provided with your new thermostat.
    1. Note the letter printed near each wired terminal
    2. For each out-of-the-wall wire:
      • find its terminal letter(s) in the left column of the table on page 9,
      • label the wire according to the right column of the table.
    3. Make the following notes in the right column of the table on page 9:EMERSON-White-Rodgers-UP400-Programmable-Thermostat-10
      You’ll need this information further in the installation process!
      Note: No thermostat installation uses all of the wires shown on page 9. In most cases, between 4 and 5 terminals are wired.
      CAUTION
      Mislabeling the wires could result in damage to your heating and cooling unit.
      Contact White-Rodgers™ Customer Service at 1-877-654-9394 if your old thermostat contains any wired terminals not listed in the table.
      If the OLD thermostat’s terminal is wired into the wall and identifi ed by this letter…
      Then label its wire with this letter:EMERSON-White-Rodgers-UP400-Programmable-Thermostat-11
  3. After labeling all the wires, use a screwdriver to disconnect each wire from its terminal. Remove the old thermostat.

Tip
Make sure that the wires don’t fall into the wall after you detach them from the old thermostat. You may choose to tape them to the wall or tightly wind them around a pencil or screwdriver.

EMERSON-White-Rodgers-UP400-Programmable-Thermostat-12

Install new thermostat’s wallplate

  1. Detach the new thermostat’s wallplate from the rest of the thermostat and position the wallplate on the wall according to the illustration below, passing the labeled wires through the wire hole in the center of the wallplate.
  2. With the wallplate fl ush against the wall, mark mounting holes with a pencil.EMERSON-White-Rodgers-UP400-Programmable-Thermostat-13CAUTION
    Do not allow wires to touch each other or parts on the thermostat. Doing so could result in damage to your heating and= cooling unit.
  3. Move the wallplate aside. Drill the mounting holes using a 3/16″ drill bit. With a hammer, tap the wall anchors, provided in the package, into the drilled holes.
  4. Position the wallplate on the wall again and screw the mounting screws into the wall anchors. Do not use a power screwdriver,you may damage your thermostat.

Match and connect wires

  1. Match each wire coming from the wall to its corresponding terminal, as shown in the illustration below. Insert each wire into the hole on the side of its matching terminal. Using a screwdriver, tighten the screw securely. DO NOT REMOVE THE WIRE LABELS.
    Tip
    No thermostat installation uses all of the wires shown below. In most cases, between 4 and 5 terminals are wired. The remaining terminals will not be used.EMERSON-White-Rodgers-UP400-Programmable-Thermostat-14
    CATION
    A maximum of one wire from the wall can be wired into each terminal.
  2. In the new thermostat, a jumper wire connects the RC and RH terminals.

EMERSON-White-Rodgers-UP400-Programmable-Thermostat-37

If, in your OLD thermostat… Then…
Terminals RC and RH (or 5, or R5)

were connected by a jumper wire,

…leave the jumper wire in place in the new thermostat.
There was a terminal R, which you then labeled RC according to 2.2.2, …leave the jumper wire in place in the new thermostat.
Terminals RC and RH (or 5 or R5)

were NOT connected by a jumper wire,

…remove the jumper wire from the new thermostat.
If you’re not sure whether terminals RC and RH were connected in your old thermostat, refer to your notes made in section 2.2.2.

Install batteries

Install 2 AA alkaline batteries (not included) into the battery compartment at the top of the thermostat.

Snap thermostat to the wallplate

CAUTION
Do not restore power to the heating and cooling system until instructed.

Failure to follow this instruction may lead to your Heating & Cooling system damage or malfunction.

Heat Pump Identification

  1. How do l know if I have a Heat Pump?
    • Check the documentation for your heating and cooling system or contact your HVAC contractor.
    • Confirm that you have a Heat Pump by checking the labels of the wires coming out from the wall (labels you attached according to the right-hand column of the 2.2.2 table).
      According to the right-hand column of the 2.2.2 table, if you have: You have:
      An “O” wire, or a “B” wire A Heat Pump
  2. How do I know if I should select On1 or On2 for my Heat Pump?
    • The labeled thermostat wires coming out of the wall indicate whether you have a1-stage or 2-stage Heat Pump.
      According to the right-hand column of the 2.2.2 table, if you have: You have:
      One “Y” wire coming from the wall 1-stage Heat Pump, select On1
      One “Y” wire and one “Y2” wire coming from the wall 2-stage Heat Pump, select On2
