ATTENTION !
ENDA ET1312 is intended for installation in control panels. Make sure that the device is used only for
intended purpose. The electrical connections must be carried on by a qualified staff and must be according
to the relevant locally applicable regulations. During an installation, all of the cables that are connected to
the device must be free of energy. The device must be protected against inadmissible humidity, vibrations,
severe soiling and make sure that the operation temperature is not exceeded. The cables should not be
close to the power cables or components.
Dual-setpoint control
On-Off control
Adjustable between1 ... 20°C.
