• Install the control panel indoors only. If the
Vacation and/or Emergency Heat switches on the
control panel will be used by the owner, mount in
a location that is readily accessible to the owner.
• Install the control panel in a non-condensing
environment.
• Do not install the control panel in a room where it
will be exposed to elevated humidity levels such
as a laundry room.
• Do not install the control panel directly to
foundation walls, HVAC equipment or ductwork,
where moisture may condense on the enclosure.
• Do not install the control panel in a location where
the temperature will exceed 140°F or will drop
below 32°F.
1. Press in the cover latch on the top of the enclosure
and pull open the cover (see Figure 2 ).
