• Turn off all power to equipment.
• If an existing Evolution Control or other control is being replaced:
– Remove existing control from wall.
– Disconnect wires from existing control.
– Discard or recycle old control.
NOTE: Mercury is a hazardous waste, if existing control contains any
mercury, it MUST be disposed of properly. The Evolution Connex
Control does not contain mercury.
• Select the appropriate Evolution Connex Control mounting
configuration. Use the standard backplate (mounting plate) provided
with the wall control, or add the decorative trim plate in addition to the
standard backplate if desired. See the Decorative Trim Plate Section
for more detail.
• Route wires through large hole in mounting plastic. The hole may be
enlarged, if required, to accommodate existing installations; avoid
opening the wire hole more than necessary. Level backplate against
wall (for aesthetic value only; the Evolution Connex Control need not
be level to operate properly) and mark wall through two mounting
holes.
• Drill two 3/16-in (4.8 mm) mounting holes in wall where marked.
• Secure mounting plastic to wall using two screws and anchors
provided.
• Adjust length and routing of each wire to reach each wire entry on the
connector backplate. Strip 1/4-in (6.4 mm) of insulation from each
wire.
• Match and connect thermostat wires to proper terminals on control
backplate. See wiring diagrams in the Wiring Diagrams Section.
