Regulation of cold with two temperature probes (S1 + S3)
This requires configuration of input D2/S4 as a second cold room store temperature probe (l120=10).
The device regulates the temperature of the cold room store taking into account the reading of both probes. Using
parameter C25, the influence of probe S3 is determined in the settings.
Examples:
C25=0 (S1: 100% S3: 0%)
C25=75 (S1: 25% S3: 75%)
C25=60 (S1: 40% S3: 60%)
C25=95 (S1: 5% S3: 95%)
This mode is particularly useful in large volume cold room stores, where there may be significant variations of
temperature.
In the event of an error in probe 3 (E3), the controller only uses the reading of probe 1. If both probes break down
(E1 + E3), the controller acts according to parameter C6.
Continuous cycle mode
This is used to quickly cool the cold room stores before
products are loaded and is activated by pressing the
key for 3 seconds.
Upon activating this mode, the compressor begins to
operate until the temperature in sensor S1 reaches the
set point value, minus the variation indicated in param-
eter C10. The value of C10 is always negative, unless
it is 0.
The unit will immediately return to normal operation.
Should it not be possible to reach this point, the de-
vice will return to normal operation once the time con-
figured in C9 has elapsed, or by pressing the
key
again for 5 seconds.
Calibration of sensor 1
Parameter C0 allows for correction of the temperature detected by sensor 1; this is particularly useful when the
sensor cannot be located in the ideal place.
Set Point locking
Parameters C2 and C3 allow for an upper and lower limit to be established for the set point (SP), to protect the
product or installation from Set Point manipulation.
Product temperature
This function allows using a temperature probe to display the product temperature.
To activate it, input 2 must be configured as “Product temperature” (I20=11), and the display of all the probes
activated sequentially (C21=0).
