Before You Start
Read the information in this section in its entirety before you begin the installation of Wiser Air.
TOOLS PROVIDED MATERIALS
• Wire stripper
• Drill
• Screwdriver
• Level
• Voltmeter
Preparation
• Disconnect power to the air conditioning and/or heating system.
• It is recommended to use a properly isolated voltmeter to conrm power is off.
• Wiring must conform to all building codes, regulations, and ordinances as required
by local and national code and regulation authorities.
• Ensure all electrical loads (air conditioners, heating elements, etc.) that will be
controlled by Wiser Air are connected to appropriate fuses to prevent overload.
• Ensure Wiser Air is suitable for the environment. Check the voltage compatibility
( 24V).
• Wiser Air outputs are rated at 1A maximum.
Location
• If this is a new installation, install Wiser Air 5ft (1.52m) above the oor surface in
accordance with applicable building codes.
• Install Wiser Air in areas with frequent occupancy and airow.
• Avoid installing Wiser Air in locations near heating/cooling devices.
• Avoid installing Wiser Air in areas with direct sunlight. The screen may become
unreadable due to direct sunlight or reection from windows, and temperature
regulation may be affected.
• Avoid installing Wiser Air behind doors, near corners, near air vents, or in areas
with high dust concentration.
Mounting
1. Keep the front of Wiser Air separate from the back plate before mounting.
2. Align the Wiser Air back plate against a wall using a level and mark the placement
of the mounting holes.
3. Using a 3/16in (4.8 mm) drill bit, drill a hole to a depth of 1 in (25.4 mm) and
install wall anchors at the marked locations. If a stud is present no anchors are
necessary.

Installation Procedure
WARNING
MERCURY HAZARD
If replacing an existing thermostat that uses a sealed tube of mercury, do not
dispose of the tube in the trash. Contact local waste management authorities for
information on the safe disposal or recycling of the mercury.
Failure to safely dispose of the mercury can result in exposure leading to
serious health damage.

Optional trim plate mounting
If you are replacing an existing thermostat, you have the option of using the provided
Wiser Air trim plate. If the hole left by the removal of the existing unit is larger than the
back plate of the Wiser Air thermostat, use the optional trim plate. Run the wires and
anchor the mounting screws through it while attaching the back plate to the wall
(Fig. 2). Make sure to attach the trim plate with the central hole oriented upwards.

Installing Wiser Air
1. Disconnect power to the HVAC system by turning off the breaker.
2. Remove the existing thermostat’s panel from the wall without disconnecting the
wiring.
3. Take a picture of the wiring of the terminal connections. If necessary label the
wires to prevent confusion (Fig. 1).

TIP: Before proceeding further determine if you require the optional trim plate.
TIP: Before proceeding further check if you require a wire extender (see Appendix).
4. Disconnect the wiring of the existing thermostat and remove the back plate.
TIP: Acceptable wire gauge for use with Wiser Air is solid 18 to 22 AWG (0.33 to 0.82mm²).
5. Pull the wires 6in (15cm) out of the wall if they are not already pulled out.
6. Insert the wires through the central hole in the Wiser Air back plate.
7. If required, strip each wire 0.25in (0.6cm) from the end (does not apply to
replacing pre-existing units).
8. Connect the wiring to the Wiser Air back plate, matching the terminal connections
to those in the photograph of the existing thermostat’s wiring or according to the
wiring requirements of your HVAC system.
TIP: See the Wiring terminals section (p.7) in this guide before going further, or contact the
Customer Care Center for assistance if necessary.

9. Gently push the wiring back into the hole.
10. Attach the Wiser Air back plate to the wall using the provided screws in the
mounting holes in the top and bottom (Fig. 2).
11. Attach the front of Wiser Air to the back plate, making sure that the front is oriented
correctly so that the terminal pins on the front panel match the pins on the back
plate. Do not use excessive force on the Wiser Air as this can damage the terminal
pins (Fig. 3).
