Features and Benefits
•
Based on IR32 Parameters
•
Real Time Clock ( RTC ) – Model Specific
(defrost based on real time – 7 day 24 hour)
•
HACCP (Hazard Analysis and Critical Control
Point) Alarm – Available on models with Real
Time Clock (RTC)
•
Models with RTC can switch the aux output
on and off based on a time program
•
Digital inputs can be programmed to be
sensors
•
Condenser temperature alarm ( option to
control condenser fan with Aux relay)
•
2
nd
Evaporator control ( second evaporator
sensor and defrost relay output option)
•
Pump down management ( Solenoid valve
(aux) output and LP switch input)
•
Block level access for programming to
simplify the movement between parameters
•
240V low temperature model

• IR33S / DN33S / MD33A are defaulted to enable “off cycle” defrost. To
make the controller cooling only r3 must be equal to 1 (H1 is now not used
for this purpose).
• Any of the sensors can be programmed to be continually shown on the
controllers LED display. If the temperature shown is not correct check that
parameter “/tI”=1 or 2. Other options are 3=Probe 2, 4=Probe 3 etc.
• The temperature alarm can now be programmed to be relative or absolute.
Default is relative (A1 = 0) meaning if AH = +5 then the high alarm is Set point
+ 5 deg C. If A1 = 1 and AH = +5 then no matter what the set point I, the high
alarm point is +5 deg C.
• It is important to note that when saving parameter changes that the “PRG”
key must now be pressed for approx 5 seconds (until the temperature comes
onto the display).
• For existing IR32 users the main parameters have basically remained
unchanged. Differential is still rd, defrost interval is still dI etc. With the addition
of the option to manage a second evaporator, dP (defrost duration) and dt
(defrost terminate temperature) have been replaced by dP1, dP2 and dt1, dt2
respectively. For normal operation the customer only needs to set dP1 and dt1.
(d_2 is only used when second evaporator management is enabled).
• Real time defrost and HACCP functions are only available in models with Real
Time Clock. Models without RTC will not permit the associated parameters to be
adjusted.
• On the “cheat sheet” we have highlighted in bold the main parameters that
need adjusting for basic operation.
• For IR33C with only one sensor (no evaporator sensor), the alarm E1 (faulty
evap sensor) is disabled by setting /A2 = 0 (probe 2 not present). Parameter d0
does not disable this alarm.
