General warning
Please read before using this manual
 This manual should be kept near the device as a quick
reference
 This device should not be used for purposes different than
described in manual
 Check application before proceeding
Safety precautions
 Must be installed by a suitably qualified person
 Check the supply voltage is correct before connecting the
device
 Do not expose the device to water or moisture, use the device
within operating limits
 Disconnect all electrical connections before any kind of
maintenance
 In case of failure or faulty operation please return to supplier
with a detailed report of problem
 Show precaution in checking the current ratings of any device
connected to relays
 Ensure probe cables are separate from power supply to avoid
interference
 In industrial applications consider the use of mains filters in
parallel with inductive loads
General description
ECS-2180 neo is a microprocessor based controller suitable for medium or
low temperature refrigeration control. It has 3 relay outputs to control
compressor fan and defrost, which can be electric or hot gas. Two NTC
temperature probes are supplied for thermostatic control and for
evaporator defrost control
Functions
Compressor
The regulation is performed according to the temperature measured by
the indoor probe (terminals 1&2). As temperature increases at reaches set
point + differential and the compressor is started. As temperature
decreases and reaches set point the compressor swill switch off. Visual
indication on the display shows when compressor relay is engaged. This
indicator flashes during a delay, such as avoiding short cycling
Defrost
The defrost mode can be selected for: electric heater or hot gas. For
medium temp application an “off cycle” defrost can be utilised where
defrost will occur when compressor is off
Defrost is interval timed and this is adjustable by user. Defrost probe will
end the period of defrosting or by interval period Defrost has visual
indication on display
Fan control (Evaporator indoor)
The fan control is configurable to run only with compressor or to run
continuously. Adjustable drip time is a feature designed to allow ice/water
extra time to be removed from evaporator. Fan motor has high temp stop
point as a safety feature preventing circulation of warm air
SET: Press for 3 seconds to change set point, display shows St
Press to increase set point
Press to lower set point

How to change parameters (Administrator menu)
Press Set for 3 sceonds:
Press
Press Set and enter administrator password 55 by using
Press to increase
Press to lower
Once 55 is reached, push set and then
Now push to go through administrator level
Differential is changed by pushing set point on C1 use and
To increase or decrease differential
Buzzer mute Press any key to silence alarm buzzer
Other common parameters, can be accessed by pushing set button with
following codes:
D4 Defrost interval set range 0-90 hours. Time between defrosts
D6 = defrost period set range 1-90 minutes. Length of defrost but this can
be over ridden by defrost probe indicating that frost is clear
A6 = Maximum temperature alarm range AL1-70 °C. High Temp alarm
A5 = Minimum temperature alarm range -40 °C– AU1. Low Temp alarm
Digital controller with defrost and fans
management

C6 Max set point range +85°C. To limit the maximum set point
C5 Min set point range -50°C To limit the minimum set point
A7 Alarm delay range 0-60 minutes. Delay before alarm activates
C7 Compressor short cycle protection range 0-90 minutes. Stops
compressor stop starting excessively
A2 Compressor run time in event of probe failure range 0-60 minutes.
Compressor will run for this timed period with no input to avoid thawing
of product
A3 Compressor stop time in event of probe failure range 0-60 minutes.
Compressor will cycle off after this period of time with no input to avoid
freezing product
D1 Evaporator probe presence 0 = disabled 1 = enabled
D2 Probe calibration range -10 to 10°C adjustment of probe input reading
if accuracy is poor due to extended probe or interference
D7 defrost stop temperature, defrost terminates when this setting is
reached
F5 fan stop temperature, fans will not run at or above this setting
D8 drip time, at end of defrost time is allowed for condensate to drip off
coil
D11 defrost mode 0 is electric heater 1 is hot gas
F1 fan mode 0 fan operates simultaneously with compressor 1 fan
operates continuously stops during defrost 2 fan operates continuously
stops during defrost and drip time 3 fan operates continuously stops
during defrost fan time delay after defrost 4 Controlled by sensor fan stops
during defrost
A full list of parameters follows (some are optional and depend on model)

Note ① only applicable when sensor is functional
Note ② Caution required when changing from Celsius Fahrenheit as all
parameters will change accordingly.

Problem solver
 Remove power from controller
 E1 or E2 check probe connections, clean plug in terminals
 Probes can be extended to 100m but should have good
watertight connections, recalibration may be required for long
extension
 LA alarm = excessive temperature, allow controller to cool
down and relocate or ventilate to keep cool
 Relay failure = check full load amperage of output to ensure
that it is below ratings on controller
 Defrost will not start = check coil temperature
 Fan will not start = check coil temperature
