Overview
The Wiring Enclosure makes it easy to install a Digi-Elite on a wall or any at surface. It replaces a 1900 box function.
It comes in two types, with a Switch (HTC# 929135-00) and without a Switch (HTC# 929135-00). The model with a
switch offers the capability of turning off the Digi-Elite.
Components
The Wiring Enclosure consists of two components, a Base and a Wiring Cover.
• The Base mounts to the wall and holds the Digi-Elite and the Wiring Cover. It is offers enough room for the output
and input wiring.
• The Wiring Cover hides all rear wiring. One type has a switch that can be used to shutdown the Digi-Elite (example:
during off-season, shutdown, and maintenance periods), to turn on the boiler and bypass the Digi-Elite operation, or to
turn the power to the Digi-Elite off.

• The Digi-Elite Base section can be mounted to the Wiring Enclosure Base using the four screws provided.
