NOTE:
Your control has already
been configured at

INTRODUCTION
This INTRODUCTION section provides an overview of the
Watlow 1500 controller. The microprocessor based
controller is capable of measuring, displaying and
controlling temperature and humidity from a variety of
inputs.
The controller is easy to use. Control functions, alarm
settings and other parameters are easily entered through
the front keypad. Limited data can be protected from
unauthorized changes with its guarded access mode
security system. Battery back-up protects against data
loss during AC power outages.
In this application the controller has been factory
configured to control temperature and humidity conditions
in your Despatch chamber. Under normal conditions, you
should not have to reprogram this controller. We have,
however, included reprogramming instructions in this
manual to help guide you through that process if it should
become necessary.
