old room temperature control
Cold room temperature is managed by modulating the electronic
expansion valve.
Probe confi guration
The UltraCella controllers have a maximum of fi ve analogue inputs, three
of which can be confi gured as temperature probes (NTC probes, high
temperature NTC probes, PT1000), the fourth as a temperature probe
or 0-10 V input, the fi fth can be confi gured as a 4-20 mA or 0-5 Vrat input.

Inside the cold room, the controller can use the following probes:
•
outlet:
•
intake;
•
defrost, placed on the evaporator, preferably where ice remains the
longest;
Probe B1 is confi gured as an ambient temperature probe and its function
cannot be changed.

For probe B4, if confi gured as a 0 to 10 V input (/P4 = 2) and for probe
B5, the logical values to be used by the controller corresponding to the
physical full scale readings can be assigned.
Par. Description Def Min Max UOM
/4L Minimum value of probe 4 (0 to 10 V input
only) 0 -50.0 /4H -
/4H Maximum value of probe 4 (0 to 10 V input
only) 100.0 /4L 200.0 -
/5L Minimum value of probe 5 0 -50.0 /5H -
/5H Maximum value of probe 5 100.0 /5L 999 -
Example: if a pressure sensor with 4 to 20 mA output is connected to
input B5 with the range -1 to 9.3 bars, set
- /5L = -1,0
- /5H = 9,3
In this case, when the probe reads 12 mA, the value associated with the
reading of B5 will be 4.1 (mid scale).
