Set point adjustment ratio / SPr
The default value is set to 0.5 and the parameter is hidden by default.
Spr defines the position of the setpoint in relation to cut-in and cut-out.
Spr = 0,5 sets the setpoint mid between cut-in and cut-out. Spr = 0 sets
the setpoint at the cutout. Spr =1 sets the setpoint at cut-in.
Set point / StP
StP is visible with KoolProg software only. This parameter defines the desired
temperature (set point). In standard operation the set point is changed by
simply pressing the “temperature up / down” buttons on ERC102; for laboratory
and assembly line you may opt for software controlled set point adjustment
(speed improvement)
Differential / diF
This defines the difference between the cut-out and the cut-in. The desired
temperature is determined by SPr and diF.

High Set Point / HSE
Low Set Point / LSE
These parameters define the temperature range limit of the controller. Once set,
the desired temperatue (setpoint) can not go above HSE or below LSE.
LSE Sets the minimum value for the set point
HSE Sets the maximum value for the set point
Cut-in and cut-out are automatically calculated from the desired setpoint (set
bybuttons on the control) and the differential. By default, cut-out and cut-in are
0,5*DiF above or below the desired temperature.
Example: The desired average temperature in the cabinet is 5 degrees, and the
differential is set to 2 degrees:

102 Reference manual – 7 PARAMETERS
Air Temperature Adjustment / tAd
This parameter is a relative value and allows adjustment of the
control sensor temperature.
For instance, at a measured temperature of 7*C and tAd set to -2K,
the input from the control sensor will be 5*C instead.
