Electrical Connection
Main Characteristics
-
Temperature settings controllable by external setting
when associating
a digital time switch, it is possible to regulate the heating in relation with a
program established by the user.
-
2 wires link
between the probe and the unit, enables the easy replacement
of the ambient thermostats of an existing installation.
-
Safety feature for “probe failure”
in case of probe disconnection, the
output will be switched 1 minute in every 4; so that in case of disconnection
during winter, it will protect the installation from frost.
-
Display
of state of the output and of the setting.
Working Principle
EK187
adjusts the temperature under the “all or nothing” principle it
is associated to an ambient probe and thus works in closed loop the
temperature settings are selected by external settings (contacts free of
potential).
EK187
is thus generally associated to a time switch or a digital
time switch in the case of absence of external signal, EK187
regulates the heating in comparison with the reference setting, a switch
enables the override of the dispensation setting.
