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.
