• “Fan” wires out as illustrated with 3M-30 below the wall opening.
As in the example: fan out the wires so that the C wire is above the C
terminal, the W above the W. This allows the 3M-30 to t snug to
the wall.
Caution
Do not allow wires to touch each other or parts on thermostat.
• Wires will position behind the 3M-30 and up over the
terminal area.
• Do not bunch wires behind the 3M-30. Feed any slack
back into the wall opening.
Connect Your Wires
• Connect labeled wires only to a terminal with the same letter label.
• Insert the wire in the terminal well and tighten the screw securely.
NOTE: If you wish you can mount the 3M-30 to the wall rst, and then connect the wires.
• The 3M-30 can be externally powered with a power source rated from 12V to 24V, AC or DC, at
300ma or greater. If used, connect to the C and RH terminals (no polarity).
