Intercom systems
Intercom systems which send voice signals over existing electrical wiring may interfere
with the operation of the Mini Timer when the intercom is in use. If the Intercom
system has its own separate wiring it will not cause a problem.
Power interruptions
When the power is restored after an outage, Lamp Modules and Wall Switch Modules
will normally be OFF. Appliance Modules have a “latching relay mechanism” and will
stay as they were before the interruption.
This means that when you first plug in an Appliance Module which you have just
purchased, it may in an ON or OFF state (the state it was in before unplugging it after
factory testing).
Battery backup
If you install two AA alkaline batteries in the battery compartment of the Mini Timer
your programmed times will be protected for up to 48 hours in the event of a power
outage. The backlight and the buzzer do not operate when the unit is running on the
backup batteries.
Battery indicator
If the batteries are low, dead, or not installed, the low battery indicator will be shown
in the display. It is recommended that you check the condition of the batteries
regularly and replace them at least once every 6 months.
