DECLARATION OF CONFORMITY AND
MANUAL RETRIEVAL
KM1E is a panel mounting, Class II instrument. It has been
designed with compliance to the European Directives.
All information about the controller use can be found in the
Engineering Manual:
ISTR-MKM_-ENG0x (“ x ” is the revision).
The Declaration of Conformity and the manual of the controller
can be downloaded (free of charge) from the web-site:
www.ascontecnologic.com
Once connected to the web-site, search:

The
KM1E-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.
Cool mode Automatic Heat/Cool
