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 page at end of install section for better understanding of wire labels from different HVAC
system makers.
IMPORTANT:
The CT110 runs on 4 AA alkaline batteries and/or the C wire if
available. If you do not have a C wire you can run a new wire from the HVAC or
use a standard 12-24V [AC or DC] wall transformer. A constant power source is
required when using a radio module.
IMPORTANT:
If you have both RH and RC you need to remove the jumper wire between these 2 terminals.
Prepare Wires
Please follow these guidelines for safe and secure wire connections:
• You will need at least 2.6” of wire for each of your connections to the CT110.
• If you do not have enough wire, splice additional wire to allow enough slack.
• Terminals accept wires from 16-22awg.
• Fan out wires below the hole as shown.
• Remove insulation 1/8” from the tip of each wire.
• When handling, take care not to damage the labels for each wire.
Caution
Do not allow wires to touch each other or parts on thermostat.
