2. GENERAL DESCRIPTION
The microprocessor-based electronic Honeywell Icon 100 Series Refrigeration
Controllers are designed to measure, display, and control the temperature of
refrigeration cases and coldrooms. The Icon 100 Series are powered by AC 230 V,
50/60 Hz, and can read from two thermistor probes (thermostat and / or defrost
probes), and has up to three relay outputs (compressor, defrost and fan).
All of the controllers operating parameters are configurable using a four button
keypad on the front of the temperature display. Access to the configuration
parameters menu is achieved through the front panel keyboard by following a very
simple security procedure, after which the required parameter values can be set
quickly and easily.
A Honeywell NTC 2k Ohm probe is supplied as standard with Icon and has a
measuring range of –50 to +90
o
C. (-58 to +194
o
F), that can be installed up to 10
meters (30ft) from the controller without requiring instrument recalibration. Icon can
also use the PT1000 thermistor probe with a measuring range of –50 to +90
o
C. (-58
to +194
o
F). Please note: you cannot have a combination of NTC or PT1000 probes
on a single controller.
All programming data is stored in a non-volatile memory (EEPROM), where it also
remains during a power failure.
The Icon 100 Series have the following features.
• display the measured case temperature as well as the alarm messages that
refer to faulty cooling/refrigeration plant functions.
•
control the measured temperature through the thermostat probe in order to
maintain it under a set limit value (main set point + differential), by activating
the compressor to lower said temperature every time it exceeds the main set
point + differential value.
• control the defrost cycles of the cooling/refrigeration plant manually or through
the programmed mode; in the latter mode it is possible to set the times of up
to four daily defrost cycles (112SR & 132SR models only)
•
control the defrost cycle time as well as the successive startup of the
cooling/refrigeration plant fan through the defrost probe. (112SR & 132SR
models only)
• Honeywell Genus

Network compatible.
• Optional Genus
