Installation
cont.
NOTE:
This thermostat is designed for use on low voltage 24 volt AC single
stage or multi-stage systems, including heat pumps with up to three stages of
heating and two stages of cooling (three stage heating available on heat pump
systems). Do not use this thermostat on systems with voltage higher than
30 Volts AC. This thermostat requires a transformer common wire for proper
installation if used as a hardwired thermostat.
Installing New Thermostat
NOTE:
When installing this thermostat in a new location, following a few
simple guidelines and the applicable building codes will give the best results.
Install the thermostat in a location that provides good airflow by avoiding areas
behind doors, near corners, air vents, direct sunlight or heat generating devices.
The wiring must conform to all building codes and ordinances as required by
local and national code authorities having jurisdiction for this installation.
1.
Always turn off the power to the air conditioning and heating system prior
to installing this thermostat.
2.
Locate the release latch on the bottom (not the back) of the thermostat.
Press the release latch in and separate the body from the sub-base of the
thermostat. Because this thermostat has 13 possible connection points,
you may need to apply moderate force to separate the parts.
3.
Set the thermostat electronics and cover down on a clean surface. Place
the sub-base on the wall in the desired location.
4.
Using the slotted mounting holes in the sub-base, mark the placement of
the mounting holes through the slots and onto the wall. Ensure the wires
come out of the wall into the center hole of the sub-base.
5.
After verifying the drill will not damage items in the wall, use a 3/16 drill to
create the mounting holes. Gently tap the supplied plastic anchors into the
holes in the wall.
6.
Place the thermostat sub-base against the wall in the desired location.
Ensure the thermostat is level, the wires are inserted in the opening, and
the mounting holes are aligned with the slots on the sub-base.
7.
Fasten sub-base to wall using supplied screws into the plastic wall anchors.
8.
Connect wires to the quick wiring terminal blocks. Use the wiring diagram
chart to ensure the old and new connections are correct.
9.
To prevent electrical shorts and potential damage to the thermostat, make
sure all wire connections are secure and not touching each other.
10.
Locate the thermostat body, and ensure the cover is still installed properly.
Using the mounting tabs on the top of the sub-base as a guide or hinge,
close up the thermostat case by pivoting the body and cover closed. The
latch on the bottom of the thermostat will click when the case is properly
closed. Because this thermostat has 13 possible connection points, you
may need to apply moderate force to close the case.
11.
Flip the front thermostat cover up and open the battery compartment door.
12.
Locate the positive [+] ends of the batteries and match them with the
positive [+] terminals located in the battery compartment. Install the two
new “AA” alkaline batteries (supplied). Close battery compartment door.
13.
Restore system power and proceed to programming and system checkout.
