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.
