HUNTER 44132 (01) PDF Document

To complete the installation of your HUNTER 44132 thermostat, you will need the following:

• Phillips Screwdriver (#2)

• Two 1.5V (AA) size alkaline batteries

Please take note of these warnings and cautions before proceeding with the installation of your HUNTER 44132 thermostat:

• Read all installation instructions before beginning installation.

• Do not disconnect the wires from your old thermostat until all wires have been properly labeled. You must label all wires properly because wire color may not indicate the function of the wire.

• All wiring must be done in accordance with local code and ordinances.

• Always turn power off to your furnace/compressor before the installation process. Failure to do so could result in damage to your thermostat and/or your heating and cooling system. Do not restore power until your installation is complete.

• This thermostat is designed for use with 24V AC/millivolt systems with a maximum of 1 amp. Higher amp or line voltage systems will cause damage to your system and increase the risk of fire.

1. Turn off power to your compressor and furnace.

2. Remove the cover to your existing thermostat. Some thermostats may have screws or other locking devices that must first be removed. Once the wallplate is exposed, locate the wire terminals and try to identify the wire designations. If the wire terminals are not visible, they may be connected to the back of the wallplate. Look for any additional screws, tabs, or locking devices to remove the wallplate. If you are still unable to find the terminals for the wires, it may be necessary to contact the manufacturer of the original thermostat.

Before disconnecting any wires, use the table below to write down your wire colors and the letter designations from the old thermostat. This will help you keep a record of your old thermostat’s wiring configuration. After writing down the wire colors and letters, use the provided terminal stickers to label the wires. To ensure wires do not fall back into the wall hole, you may tape them to the wall, or wrap them around a pencil.

Here are some tips to help you in wiring your HUNTER 44132 thermostat:

• Only 1 reversing valve is needed to run a heat pump. If both “O” and “B” are present, “B” may be a common wire.

• Often, 2-wire heat only systems do not have terminal labels. Connect 1 wire to the Rh terminal and the other to W.

• If you have a 3-wire hot water system, the damper valve control wire will be labeled and attached to the “A” terminal.

1. Remove the mounting plate by pulling it straight off the back of the Thermostat.

2. Pull the wires through the back of the mounting plate, ensuring none of the wire labels are removed.

3. Using a Phillips Screwdriver, partially install 1 screw into the top hole of the thermostat. Ensure the thermostat is level using the bubble level on the mounting plate, then install the other screw. Tighten both screws until secure.

1. First, check the charts provided in the PDF to identify your system type (Conventional or Heat Pump).

2. Raise all of the levers on the terminals you will be using. Heat Pump installation labels are on the left of the terminal blocks, and Conventional labels are on the right. If your installation does not call for the jumper (located between the RH and RC terminals), remove it now.

3. If one of the terminals you need has a tab in front of it, use your finger to break the tab away. Only break tabs you know you will be using.

4. Insert the bare end of each wire all the way into the appropriate hole in the terminal block that matches the wire label, then lower the lever. This will lock each wire in place. Do not insert wires into the holes in the top of the mounting block; they should be inserted into the front. Tuck excess wire back into the wall after they have been locked in the mounting plate.

Before mounting the thermostat onto the wallplate, turn it over to find the 2 switches located on the circuit board next to the battery compartment.

1. Set the system switch to “Conv” if you have a conventional HVAC system or “HP” if you have a heat pump system.

2. Set the furnace type switch to “Elc” if you have an electric conventional system or a heat pump. “Gas/Oil” will be used if you have a gas or oil-based conventional system.

Note: Conventional systems use the compressor for air conditioning and a separate furnace for heat. Heat pump systems use the compressor for both heating and cooling.

Lay the ribbon across the battery compartment and install 2 (AA) batteries into the back of the thermostat over it. Then, snap the thermostat on to the mounting plate. Refer to the “Setup” section of your owner’s manual to continue setup, scheduling, and daily use.

If your old thermostat is a heat pump from one of the listed manufacturers and your wire labels do not match, you can use the following cross-reference chart:
