1. SAFETY INSTRUCTIONS
A. Keep this instruction booklet where it can always be easily consulted
by the operator or by maintenance personnel.
B. Warning: hot components may be inside the plastic housing of the
controller.
C. No user-serviceable parts are inside the plastic housing of the
controller.
D. The controller and any device connected to it must be installed in
compliance with the Safety Regulations in force. If these regulations
are not respected during installation, and if our product is not installed
in compliance with the indications given in this instruction booklet, then
this may cause a reduction in the safety level of the controller. In
particular, the ambient operating conditions for the controller given in
our technical data must be complied by; absolutely avoid: water
condensation or excessive humidity, exposure to steam, corrosive - or
toxic gases, contact with any type of liquid, and exposure to shocks or
to extreme vibrations. Not respecting the above indications could
cause malfunctions and entail unpredictable consequences, e.g., in the
worst cases, dangerous electrical discharges on probes or other parts
of the instrument.

ICON 100 SERIES INSTALLATION GUIDE
E. This controller is guaranteed by Honeywell to have a specific immunity
level, in compliance with CE regulations, against irradiated and
conducted electromagnetic disturbances. By irradiated electromagnetic
disturbances we recommend to screen the controller with a metal
screen connected to ground. To eliminate, or at least reduce
conducted disturbances, which not only could propagate through the
mains but also through the probes or the connected loads, carry out
the electrical wiring according to the indications given in this instruction
booklet. If necessary, use filters with suitable characteristics for specific
applications and for the detected type of disturbance.
F. If the type of probe to be used will directly touch foodstuffs, make sure
that it is in compliance with the local sanitary and health regulations.
G. The controller has no type of protection for the connected loads, so
these must be protected against short circuits, over-current or overvoltage, excessive temperature, etc., by suitable protective means
(such as fuses, suitable thermo-magnetic circuit breakers, thermal
protections, etc.). At any rate, the electrical power lines that supply
both the controller and any other device connected to it, either directly
or through a transformer, must be manufactured in compliance with the
regulations in force.

ICON 100 SERIES INSTALLATION GUIDE
H. When the controller is used in appliances where any malfunction of
said controller could cause a form of risk to persons, animals or things,
it is ABSOLUTELY MANDATORY to provide a suitable
protective/safety device, in addition to the controller, which
independently starts to operate in case of a failure.
I. The controller cannot be used as a critical component in life-support
devices or systems without a written approval expressly issued by the
legal representative of Honeywell.
CAUTION
Disconnect the power supply before you begin installing the Icon controller.
Do not reconnect the power supply until you have completed installation.

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 oF), 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 oF). Please note that 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.

ICON 100 SERIES INSTALLATION GUIDE
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
®
comms. Module.

4. INSTALLATION
4.1 Introduction
The controller must be installed in a place where it is protected from extreme vibrations, impacts, water, corrosive gases, steam etc. and where temperature and humidity do not exceed the values given in the technical
specification table (see page 11). The same instructions are also valid for
the probes.
4.2 Thermistor Probe
The thermistor probe must be installed in a place where it is protected from
direct airflow (i.e., away from fans or doors), so that the average
temperature can be measured.
4.3 Defrost Termination Probe
The defrost termination probe must be installed in the coldest area between
the evaporator fins, i.e., where the most ice will form, and not near the
defrost heater or near the area that warms up first during defrosting, in order
to avoid early termination of the defrost cycle.

ICON 100 SERIES INSTALLATION GUIDE
4.4 Electrical Wiring
We would recommend protecting the controller power supply from
electromagnetic disturbances, voltage peaks, etc. This can be easily done
while wiring by following the instructions below:
• separate the power supply cables of the compressor, motors, etc.
from those of the controller;
• keep the probe cables, the controller power supply cables, and the
load power supply cables separate and sufficiently far away from
each other, so they do not cross or form spirals.
4.5 Applications in Critical Environments
When used in particularly critical industrial environments the following
precautions can also be useful:
• Use mains network filters to reduce disturbances at the controller
power supply, as well as filters for the loads in order to attenuate
disturbances at the controller relay outputs;
• Use screened probe cables connected to the grounding system, if the
previous indications are not sufficient;
• In the event of strong radio disturbances screen the entire device with
a metallic screen and connect it the grounding system.

4.6 Fitting
lcon is supplied in a panel-mount enclosure. While fitting the controller we
recommend to leave enough room at the back in order to avoid
compressing or excessively bending the cables. Overall instrument size and
panel cut-out dimensions are given in Fig. 1. below.

4.7 Connections
We recommend the use of wire gauges adequate for the given load power
ratings in order to avoid damage to the screw connector.
