uuSECTION 1: INTRODUCTION
1.1 WHAT IS A ROBERTS GORDON®BZC
CONTROLLER?
The ROBERTS GORDON®BZC 700 is a
micro processor based controller designed
for the most efficient control of CORAYVAC®,
BLACKHEAT®and CARIBE®heaters.
The control is capable of giving control out-
puts from 9 relays, 7 of which afford heating
zone control capabilities. The control also
features 8 inputs which are used for signal
condition monitoring.
1.2 GENERAL REQUIREMENTS
The ROBERTS GORDON®BZC series of
controllers are supplied pre-configured for
their application and only for use with
ROBERTS GORDON®infrared heating
equipment. Failure to comply with the instal-
lation instructions and configuration may
invalidate the limited warranty set out on
Page 10, Section 5 .
Mount the ROBERTS GORDON®BZC
Controller Quick Programming Guide next to
the controller for easy reference of program-
ming steps.
See Page 3, Section 2, Figure 2.
