IR33 Platform Technical tips IR33S / DN33S / MD33A are defaulted to enable off cycle defrost. To make the controller cooling only r3 must be equal to (H 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 = 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 (A = ) meaning if AH = +5 then the high alarm is Set point + 5 deg. If A = and AH = +5 then no matter what the set point I, the high alarm point is +5 deg. 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). or 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addition of the option to manage a second evaporator, dp (defrost duration) and dt (defrost terate temperature) have been replaced by dp, dp2 and dt, dt2 respectively. or normal operation the customer only needs to set dp and dt. (d_2 is only used when second evaporator management is enabled). Real time defrost and HAP functions are only available in models with Real Time lock. Models without RT will not permit the associated parameters to be adjusted. the cheat sheet we have highlighted in bold the main parameters that need adjusting for basic operation. or IR33 with only one sensor (no evaporator sensor), the alarm E (faulty evap sensor) is disabled by setting /A2 = (probe 2 not present). Parameter d does not disable this alarm. 6
