Programming the Relay
This is only applicable if switch 3 is set to “4 Schedules”
and the Timer is connected to a tekmarNet
® 4 system.
The relay contact on the back can be programmed to follow
one of the four schedules available in the Timer. The schedule
must first be turned to “On” before the relay contact can
be programmed to follow it. When the schedule is in the
“Wake” or “Occupied” events, the relay will be in the normal
state. When the schedule is in the “Unoccupied” or “Sleep”
events, the relay will be in the non-normal state, which can
be programmed via switch 2 on the back of the Timer.
Locate the Relay Schedule in the Misc menu (Must be
in the “User” or “Adv” access level) to program which
schedule the relay will follow. •
Backlight
Use the Timer’s backlight to increase the visibility of the
display. The backlight can be set to On, Temporary, or Off.
If On is selected, the backlight remains permanently on.
If Temporary is selected, the backlight comes on for 30
seconds when a button is pressed. If Off is selected, the
backlight remains permanently off. By default, the backlight
is set to Temporary. Locate the Backlite setting in the Misc menu. •
