D – Hysteresis
When programming the‘d0’ i ‘d1’ parameters (the minimal and maximal user preset temperature) attention
should be paid to the fact that the ‘d3’ hysteresis value causes additional shifting of the temperature to higher
or lower values with relation to the user preset temperature level.
This is particularly significant with regard to the so-called “plus” equipment which should always be operated at
the temperatures above 0
o
C.
EXAMPLE:
As the Manufacturer of the refrigeration unit (refrigerated counter) (temperatures above 0
o
C), we require the
unit to allow the operation within the temperature range that does not exceed the values specified below:
Deactivation min: 2ºC. Activation max: 10ºC
Symmetric hysteresis for ‘d3’ even values
Symmetric hysteresis for ‘d3’ odd values
Example No. 1.
The ‘d3’ hysteresis it set at, for example 2ºC
For this hysteresis value, the parameters should be
set as follows: ‘d0’ at 3ºC and‘d1’ at 9ºC
Example No. 3.
The ‘d3’ hysteresis it set at, for example 3ºC
For this hysteresis value, the parameters should be
set as follows: ‘d0’ at 3ºC and‘d1’ at 8ºC
Example No. 2.
The ‘d3’ hysteresis it set at, for example 4ºC
For this hysteresis value, the parameters should be
set as follows: ‘d0’ at 4ºC and ‘d1’ at 8ºC
Example No. 4.
The ‘d3’ hysteresis it set at, for example 5ºC
For this hysteresis value, the parameters should be
set as follows: ‘d0’ at 4ºC and ‘d1’ at 7ºC
