3.5.1 Mode Selector Switch
The DEZ Series 1000 unit has a three-position
selector switch located on the front side of the unit.
The table below describes the modes of operation set
by the switch:
Mode
Description
OFF
Unit is off, power is still live if the main
disconnect is On; the white “Power On”
indicator light is illuminated.
ON/
LOCAL
Unit is on and runs continuously; green
“Unit On” indicator light is illuminated.
AUTO/
REMOTE
Unit cycles on and off in response to a
humidistat or Remote Start/Stop signal;
green “Unit On” indicator light is
illuminated when the unit is running.
NOTE:
The unit will not operate in the AUTO mode
unless a humidistat is installed or the appropriate
connection is made on the unit terminal block to enable
remote start/stop control of the dehumidifier. Refer to the
electrical diagram for specific wiring connections.
NOTE:
The reactivation blower and the rotor may
continue running for five minutes after the unit cycles off
to remove residual heat from the unit (dependent on
controller).
3.5.2 Hour
Meter
An hour meter inside the electric box gives the
elapsed run time for scheduling maintenance.
3.5.3 Control Panel Lights
The unit is equipped with indicator lights to notify the
operator of the current status of the unit. The green
“Unit On”
and red fault indicator lights are equipped
with “press-to-test” capability. This can be used to
verify lights are working. If a light does not illuminate
when pressed, it may be burned out or the electrical
connections may be faulty. For specific information
regarding troubleshooting indicator lights, refer to the
Refer to section 6.0, Troubleshooting and to the
electrical drawing provided with your unit.
The light icon next to the light name in the
following text contains the light’s color:
W
for white,
G
for green and
R
for red.
POWER ON
This illuminates white when main power is supplied to
the unit.
UNIT ON
This illuminates green when main power is supplied to
the unit and the unit is running.
3.5.4 Optional Fault Indication Lights
This unit may be equipped with optional, fault
indication light(s). Refer to the DIN Sheet that is
provided with the unit for the characteristics of this unit
and the optional features that are included.
SUMMARY FAULT
If unit is equipped with an E2 controller, this indicator
will be provided to illuminate red when any of several
pre-programmed faults occur, such as a high
reactivation temperature fault, rotor rotation fault, a
fault with the unit motors or insufficient reactivation
airflow across the air proving switch. As an option, the
controller may be programmed to activate the
summary fault light upon detecting other pre-defined
fault conditions or to provide certain status
notifications such as dirty filters.
