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

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
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
