The KR1E-xDRRRDxx controller is pre-configured (default

configuration) for wine applications where there is the

need to cool or reheat in thermostatic mode (on/off with

hysteresis) a tank with a PT100 probe in mono relay

output (Heat and Cool on OP1).

Heat mode

The controller action type can be identified by the color of the upper display (measurement):

Red: Heat mode only

Green: Cool mode only

Orange: The controller responds to temperature changes and selects the appropriate control mode

by operating the appropriate control output and displaying the setpoint to be reached.

The numbered red LEDs indicate, when lighted, the active (on) state of the corresponding relay output.

The change of the control direction between heating and

cooling is done by pressing the key for at least 1 s.

When the upper display flashes once (indicating that the

command has been accepted), release the key. The

instrument points out the selected action by changing

the color of the upper display.

In 30, the navigation between the different groups is

carried out by means of the key . To access the

parameters of the selected group, press the key and

modify the value using the / keys. A brief pressure

on the key is used to exit the group, a long one to exit

the configuration menu.
