Hand Held Device

The Hussmann Interface Module may be operated
from either battery power or from a 120V/12VDC
transformer. When using the transformer, connect
Module before plugging in the transformer. The
startup screen will automatically appear.

CORPORATION

VER 1.30

When battery operated, the Module will shut down
if the key pad has not been used for three minutes.
When a transformer is used, the hand held module
will beep and remain on.

If the battery is too weak to function, the menu
screen will become faint or not come up at all. If
the battery is completely without power, the hand
held module will beep and show an alarm
message. There is also a Low Battery message
that appears at the Main Menu for Protocol™.

Regardless of the power source, if Protocol™ is
not communicating with the hand held module, a
beep will sound and a
appear. If the Protocol™ system is without power,
the hand held module will beep and show an

ALARM message.

2-DEFROST / TEMPCKT

This is a read-only menu. This screen shows the
current operational status of Defrost Circuits and
associated temperatures as provided by Auxiliary
inputs.

NAME gives a description of the case loads for this
defrost circuit.

STATUS indicates whether the defrost circuit is in
defrost (DEFR), refrigeration (REFR), or a
Manually Forced condition (F-DEFR, F-REFR).

T

EMP-CTRL indicates whether temperature control

is available for this circuit. This control feature
allows the refrigeration solenoid to be operated ON
and OFF to maintain a temperature setpoint.

AUX #X provides the actual temperature reading
of the circuit. Note that X will be a number
between 1 and 8 depending upon the Temp/Circuit
number you are currently accessing.

REFRIG is the status of the defrost/refrigeration
relay. ON indicates that power is being fed to the
solenoid. OFF indicates that the solenoid is de­energized.

R

EF is an internal setpoint used by the Temp

Control algorithm. This number will increase up /
decrease down dependent upon the relationship of
the temperature reading (AUX #) and the circuit
setpoint.

Press ENT to view additional circuit information.

Note: Temperature Control is available on Hand
Held Devices V2.40 or greater.
