What wires do you have?
Make sure your wires are labeled. This may require you to find the
other end
connection for each wire on your heating or air conditioning equipment and
read the label there. Refer to the Wire Reference on page 39 for better
understanding of wire labels from different HVAC system makers.
IMPORTANT:
C wire or 24VAC power is required for the
Environ to operate. If you do not have a C wire, you can
run a new wire from the HVAC to the Environ or provide
24VAC power to operate the Environ using a standard
24VAC wall transformer.
IMPORTANT
:
If you have both RH and RC, remove the
metal jumper-clip between these 2 terminals.
IMPORTANT
:
If you have both O and B, refer to page
39 for wiring information.
Prepare Wires
Please follow these guidelines for safe and secure wire connections:
x
You will need at least 2.6” (66 mm) of wire for each of your
connections to the Environ.
x
If you do not have enough wire, splice additional wire to allow enough
slack.
x
Fan out wires below the hole as shown.
x
Remove insulation 1/8” (3 mm) from the tip of each wire.
x
Take care not to damage the labels for each wire in handling.
Do not allow wires to touch each other or parts
on the thermostat.
