Watlow EZ-ZONE Automatic Temperature Controller
With Honeywell Modulating Motor and Maxon Butterfly Valve
Introduction
Your Delux grain dryer is equipped with an automatic temperature control system that is simple and
takes the hassle out of continually watching the dryer for temperature fluctuations. Simply set your
target plenum temperature and the controller will maintain that temperature. To better understand the
controller and how to use it, please spend a little time to familiarize yourself with common keys and the
display.
A) Upper Display (Process Value) – In the home page this is the current plenum
temperature. Otherwise it is the upper display parameter in other menus.
B) Lower Display (Set Point) – In the home page this is the user-defined value that sets the
desired operating temperature (plemum temperature). Use the “UP” & “DOWN”
buttons (I & J) to increase or decrease the setpoint. Otherwise it is the lower display
parameter in other menus.
C) Reset Key – This key is essentially a “BACKSPACE” key to any of the programming
menus. Press and hold for two seconds to return to the Home Page. From the Home
Page it can clear alarms and errors if clearable.
D) EZ Key – This key can be programmed to do a variety of functions. Shipped from factory
(DELUX) this key has no programmed functions.
E) Advance Key – This key advances through parameter prompts.
F) Temperature Units – Indicates whether the temperature is displayed in Fahrenheit or
Celsius.
G) Output Activity – Numbered LEDs indicate activity of outputs. A flashing light indicates
output activity and systems are normal .
H) Percent Units – Lights when the controller is displaying values as a percentage or when
the open-loop set point is displayed (manual mode).
I, J) Up & Down Key – In the Home Page, adjusts the set point in the lower display (B). In
other menus, changes the upper display (A) to a higher or lower value, or changes a
parameter selection.
