equivalent replacement product, provided the supplier determines that the returned Product is defective and
the Customer is otherwise eligible to receive a replacement product;

be caused by something other than defects in materials or workmanship, including without limitation, if the
product:

alteration in writing;
• was subject to abuse, neglect, electrical fault, improper handling, accident or acts of nature;

CONSEQUENTIAL DAMAGES RESULTING, DIRECTLY OR INDIRECTLY, FROM ANY BREACH OF ANY WARRANTY,

Step 3. Connect the Wires
The next step is to connect the wires between the thermostat, diode, wiring
harness, and HVAC equipment.
1. Connect the C wire coming from the thermostat to the C terminal on the
STAT side of the wiring harness. You can repurpose the wire that would
have been connected to W on a 4-wire thermostat.
2. Connect the RC/RH and G wires from the thermostat to the RC/RH and G
terminals on the STAT side of the wiring harness.
3. Connect the output from the diode to the Y terminal on the STAT side
of the wiring harness. You can re-use the wire that would have been
connected to Y on a 4-wire thermostat.
4. Connect the RC/RH, G (fan), Y, C, and W wires on the EQUIP side of the
wiring harness to the matching terminals on your air hander.

Step 4. Power On the System
After you have completed the wiring, you can power on and test the system.
1. Re-attach the thermostat to the backplate. Ensure that the pins on the
thermostat align with the terminal block on the backplate.
2. Power on the HVAC equipment. The thermostat should automatically
power on.
3. Test your wiring by alternately adjusting the set temperature and running
the different heat, cool, and fan modes.
4. Once you are satisfied the wiring is correct, re-attach the wiring harness’s
front cover. Make sure the wires exit the module via the wire channel.
5. Re-attach any cover panels that you previously removed on the HVAC
equipment
