ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury,
death or equipment damage.
Before installing, modifying, or servicing system, the main
electrical disconnect switch must be in the OFF position.
There may be more than 1 disconnect switch. Lock out and
tag switch with a suitable warning label.
!
WARNING
1. Turn off all power to equipment.
2. If an existing User Interface or control is being replaced:
a. Remove existing control from wall.
b. Disconnect wires from existing control.
c. Discard or recycle old control.
NOTE
: Mercury is a hazardous waste, if existing control contains
any mercury, it MUST be disposed of properly. The User Interface
does not contain mercury.
3. Select Infinity Control mounting plastic (recess mount or
surface mount and decorative backplate if desired).
4. Route wires through large hole in mounting plastic. Level
rear plastic against wall (for aesthetic value only -- Infinity
Control need not be level to operate properly) and mark
wall through two mounting holes.
5. Drill two 3/16--in (4.8 mm) mounting holes in wall where
marked.
6. Secure mounting plastic to wall using two screws and an-
chors provided.
7. 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.
8. Match and connect thermostat wires to proper terminals on
User Interface backplate. See wiring diagram Fig. 11, 12,
and 13.

NOTE
: It is not mandatory that the above color code be used, but
each ABCD connection in the system MUST be wired consistently.
A separate ABCD Connector comes inside packaging and should
be used when connecting to furnace (or fan coil). Ensure connector
is inserted properly into circuit board. (See Fig. 14.)
