Honeywell RTH6300B Programmable Thermostat Installation Guide

Honeywell RTH6300B Programmable Thermostat

Installation is easy — even if you’ve never done it before!

Your new thermostat has been designed for fast, easy installation. Just follow the simple, step-by-step instructions in the following pages.
Install in three simple steps

• Label wires and remove your old thermostat.
• Install and wire your new thermostat.
• Set your new thermostat to match your heating/cooling system.

Installation tips

• Have everything you need ready to go before you begin.
• Do not use wire color as a guide. Use wire labels instead.

Pre-installation checklist

Check to make sure your package includes the following items:

Required tools & supplies

• No. 2 Phillips screwdriver
• Small pocket screwdriver
• Drill
• Drill bit (3/16” for drywall, 7/32” for plaster)
• Hammer
• Pencil
• Electrical tape
• Level (optional)
• Two fresh AA alkaline batteries

Remove your old thermostat

1. Turn off power at the heating/cooling system (or fuse/circuit-breaker panel).
2. Remove the cover and thermostat, but leave the wallplate with wires attached.

Did you purchase right thermostat? Count wires to check

Count the number of wires coming out of the wall and attached to terminals in your old thermostat. If any of them are attached to a terminal marked “C” or “C1” do not count that wire in your total.
If the total (not counting C or C1) is 5 wires or less, proceed to the next page. If you have 6 or more wires, your new thermostat may not be compatible with your system. Stop installation and call 1-800-468-1502 for advice.

Identify wires you will not use

If any wires are not attached to terminals in your old thermostat, do not connect them to your new thermostat.
If a wire is attached to a terminal marked “C” or “C1,” disconnect it.You will not connect it to your new thermostat.
Wrap the bare metal ends of each unused wire with electrical tape, so it cannot touch and short out other wires.

Label wires and remove old wallplate

Use a screwdriver to disconnect wires one by one.As you disconnect each wire, wrap it with the label matching the letter on your old thermostat. (Adhesive labels are supplied in your thermostat package.)
Remove the old wallplate only after all wires are labeled. Be careful not to let loose wires fall into the wall opening.

IGNORE WIRE COLORS: Use only letter designations to identify wire types.

Remove the wallplate and install a quick reference card

Insert a finger into the wire hole and pull to remove the wallplate from new thermostat.

Insert a quick reference card into the slot in the back of the thermostat.

Mark wallplate mounting position

Mount wallplate

Connect wires (typical installation)

Labels don’t match?
If labels do not match letters on the thermostat, see next page.

Connect wires (less common wire designations)

If labels do not match letters on the thermostat, check the chart at right and connect to the terminal as shown here (see notes, below).

1. If wires will be connected to both R and Rc terminals, remove the metal jumper (see page 12).
2. Do not connect both O and B if you have a heat pump. Connect O wire to O/B W. Wrap B wire with electrical tape and do not use.
3. Do not use C, X or B. Wrap bare end of wire with electrical tape.

Install batteries

Install two fresh AA alkaline batteries in back of the thermostat. After installation, batteries can be changed without removing the thermostat from the wall (see Operating Manual for more information).

Mount thermostat and restore electrical power

1. Align the 4 tabs on the wallplate with corresponding slots on the back of the thermostat, then push gently until the thermostat snaps into place.
2. Restore electrical power at the heating/cooling system, or at the fuse/circuit-breaker panel.
   TIP: If wires interfere when you try to mount the thermostat, push excess wire back into the wall opening.

System setup (set the thermostat to match your system)

Next, you must set the thermostat to control the heating and cooling system in your home. Press and hold the and FAN buttons to enter system setup.
