The Hager EH110 is a programmable time switch suitable for electrical installations in 230VAC systems of protection class IP20. Its main purpose is to control the switching on and off of one or several electric circuits, at certain predetermined times each day. Its operating principle is based on one or two weekly independent programs. The EH110 has an intuitive user interface, consisting of up and down arrows, a day dial, two selector switches (1 and 2) and three keys (P1, P2 and conf/clear). The user is able to configure the switching times and days for each program with the help of these keys. The device is factory programmed for immediate use with daily switching on and switching off at the same times every day. The EH110 has a system of LED-indicators which provide status information and alarms. In the case of an alarm, the LED’s will blink, with a graphical description of the type of alarm indicated. In addition, this device has an automatic summer/winter time switching function and can be adjusted from the EH110 configuration menu. This product is also suitable for use in installations located in strict environments (out door) due to its sealed front and back covers, self-extinguishing housing (IP20) and class II protection.
