6.6. Step 5: Set Up the MultiFlex
ESR
Before setting up the MultiFlex ESR evaporator
stepper regulator, you must have completed
steps 1-4 so that the MultiFlex ESR boards are
added and configured correctly in your Standard
Circuit applications. In this step, you must spec-
ify the type of valves being used and (if neces-
sary) the specifics of the valve such as step rate
and maximum number of steps.

3. Use the arrow keys to highlight MultiFlex
ESR and press

or simply enter the
number next to it. The MultiFlex ESR Sum-
mary screen will open.
4. If more than one MultiFlex ESR is listed,
choose the one you wish to edit, and press

A. General Setup Screen
The General Setup screen is where general prop-
erties of the MultiFlex ESR application are spec-
ified. The only field on this screen you will edit
is the
Name field. If you wish to assign a name
to this MultiFlex ESR application, enter it in this
field; otherwise, move to the Valves Setup
screen.
Temp Fail EEPR % The MultiFlex ESR uses the value set
in this field if the case temperature
sensor fails. This feature is always
available.
Temp Fail Use
Avg % If an ECT Flow valve has been se-
lected, the MultiFlex ESR will have
the option to use the daily average
valve % if the case temperature sen-
sor fails. This option is only available
when valve type is set to ECT Flow.
Comm Fail EEPR % The MultiFlex ESR uses the value set
in this field if a communication fail-
ure with the board occurs. This fea-
ture is always available.
Comm Fail Use
Avg % If an ECT Flow valve has been se-
lected, the MultiFlex ESR will have
the option to use the Daily Average
Valve % if a communication failure
with the board occurs. This option is
only available when the valve type is
set to ECT Flow.
CommFailDefrost If enabled (default), the scheduled
defrost will occur if the board is of-
fline (comm fail). If disabled, and the
MultiFlex ESR board containing the
valve associated with this circuit is in
comm fail, the standard circuit will
skip any scheduled defrost and an ad-
visory will be generated. Additional-
ly, two configurable advisory
parameters will appear.
