The MultiFlex CUB
Hand-Held Interface
The MultiFlex CUB Hand-Held Terminal
(HHT) interface allows you to view status of
condensing unit systems and configure setpoints
directly on the board. If you are using CUBs sep-
arate from a central E2 or Einstein system, the
Hand-Held Terminal will be the only program-
ming interface you may use.
IMPORTANT! If the CUB boards are con-
nected to a parent E2 or Einstein, do not use the
Hand-Held Terminal to make permanent con-
figuration changes. Changes made to an E2- or
Einstein-connected CUB via the Hand-Held Ter-
minal are designed to be temporary. The parent
controller does not recognize any configuration
changes made by the HHT, and when the HHT is
unplugged from the CUB, E2 or Einstein will
change all parameters changed with the HHT
back to their original values.

When you first plug in a Hand-Held Termi-
nal into the MultiFlex CUB’s HHT jack, the dis-
play will show the first of six status screens. The

the six screens in order at the rate of three sec-
onds per screen. To toggle automatic scrolling
OFF and ON, press the Point “.” key on the
Hand-Held Terminal.
You may also scroll through the status
screens manually using the UP ARROW and
DOWN ARROW keys.
