Honeywell Home RTH2410B1001 Programmable Thermostat
Identify System Type
- Gas, oil or electric furnace
- Central air conditioner
- Hot water system with or without pump
- Millivolt system
- Central heating and cooling system
- Heat pump without auxiliary/backup heat
- Heat pump with auxiliary/backup heat
Remove Old Thermostat
- Turn power off at the heating/cooling system
- Remove old thermostat, but leave wall plate with wires attached
- Do not remove wallplate yet
Identify Wires
- Do not use non-connected wires
- Do not use C or C1 wires
- Identify and label each wire
- IGNORE WIRE COLORS: Use terminal screw designations to identify wires.
Mount New Wallplate
- Loosen the locking screw at the bottom of the thermostat. Note that the screw is captive and cannot be removed from the wallplate.
- Separate the thermostat from the wallplate as per Position the wallplate against the wall and mark hole positions with a pencil.
- NOTE: Levelling is for esthetics only and will not affect the performance of the thermostat.
- Drill holes at the marked positions and insert supplied wall anchors.
- Pass the wires through the large opening located at the bottom center of the wallplate as per
- Secure the wallplate to the wall with supplied mounting screws as per Connect the wires to the terminals
Connect Wires
Conventional Systems (Typical Wiring
- Match each labeled wire with the terminal having the same letter.
- Loosen the terminal screws using a screwdriver, insert the wires, then tighten the screws.
- Push any excess wire back into the wall opening
Conventional Systems (Alternate Wiring)
- Do not use C, C1 or X wire. Do not use B wire if you already have O wire. Wrap bare end of wire with electrical tape.
- This thermostat cannot be used if your old thermostat had any two of the following wires: R, RC, RH, 4 and V.
- Place a jumper (piece of wire) between Y and W/AUX if you are using a heat pump without auxiliary/backup heat.
Heat Pump Systems with Auxiliary/Backup Heat (Typical Wiring)
- Match each labeled wire with the terminal having the same letter.
- Loosen the terminal screws using a screwdriver, insert the wires, then tighten the screws.
- Push any excess wire back into the wall opening
Heat Pump Systems with Auxiliary/Backup Heat (Alternate Wiring)
- If your old thermostat had E and Aux wires (or alternate wires), connect both wires to AUX terminal.
- Do not use L wire. Wrap bare end of wire with electrical tape.
- Do not use C or X wire. Do not use B wire if you already have O wire. Wrap bare end of wire with electrical tape.
- This thermostat cannot be used if your old thermostat had any two of the following wires: R, RC, V or VR.
Set Heating Fan Control
- HG Leave the jumper in this factory-set position if you have a gas or oil furnace.
- HE Place the jumper to this position if you have an electric furnace.
Incorrect jumper setting: An incorrect setting is noticeable in a gas or oil heating system. When heating starts, you will initially feel cold air coming out of the vents as the fan is running before the furnace has enough time to heat up the air
Set Heat Pump Reversing Valve
- O Leave the jumper in this factory-set position if you have connected O wire to the O/B terminal.
- B Place the jumper to this position if you have connected B wire to the O/B terminal.
Incorrect jumper setting: The heat pump operation will be reversed, i.e., it will cool in Heat mode and will heat in Cool mode
Install Batteries and Thermostat
- Install 2 AAA batteries on the back of the thermostat.
- Align the two brackets on the top of the thermostat with the corresponding slots on the top of the wallplate.
- Push the thermostat against the wallplate.
- Tighten the screw at the bottom of the thermostat.
- Turn power back on at the heating/ cooling system.
System Setup
- Press the Up and Down buttons simultaneously (for three seconds) until the display appears as shown below. See table on the next page
- Press the Up or Down button to change the option.
- Press the Up and Down buttons simultaneously for one second to advance to the next function.
- When the last function is displayed, press the Up and Down buttons to save any changes and exit the menu.
