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

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 .
1 Click: Temperature setpoint
Spr = 0,5 sets the setpoint mid between cut-in and cut-out . Spr = 0 sets
Sub function: Up
the setpoint at the cutout . Spr =1 sets the setpoint at cut-in .

Differential / diF
Sub function: Down
This defines the difference between the cut-out and the cut-in . The desired
temperature is determined by SPr and diF . 1 Click: Temperature setpoint

High Set Point / HSE
1 Click: Temperature setpoint
1 Click: Temperature setpoint
Low Set Point / LSE
Sub function: Down
Sub function: Up
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

Sub function: Down
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

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 .
