PRESENTATION
This is a weekly 4-channel time switch used to automate the control of hea-
ting, lighting, watering system and access control installations, etc. in homes
and businesses.
• You can create 84 on or off programming steps for distribution on the
4 channels.
• 1 programming step is defined by the following:
• the switch time (for example 7:35 am)
• the day(s) of the week (for example: Monday, or Monday, Tuesday and
Wednesday)
• switch state (on or off)
• Manual control of on or off forcing (permanent on or off) by channel, with 3
position switches.
• Time delayed forcing (exception) adjustable from 1 hour to 99 days per
channel.
• Input that lets you simultaneously force the 4 channels to be selected off.
Important: at MONOTRON 400 allows initial switch on, you must reset ("reset")
and clear the memory before programming. The "reset" key can be activa-
ted with a pen tip, for example (do not use a sharp object that might dama-
ge the key).
