group do?
It makes it so that when you turn ON the group, :A
the relays don’t come on – only the group
status changes to ON and the relay timers are
disabled.
Why would someone want to use “NO :Q
AUTOMATIC ON”?
So they can take disable relay-timers without :A
actually turning the relays on. For example, if
the customer wants to turn lights on with a
switch early in the morning, and not have them
automatically shut off after an hour (timer
mode), they would need to turn the MAINTAIN
+ TIMER group on with a schedule. However, if
they don’t want the actual lights to turn on until
they use a switch, they would set the group to
“No Auto On”. This would take the relays out
of Timer mode, but not turn them on with the
schedule. This saves energy until someone enters
the room and switches the lights on.
When must a switch button be programmed :Q
to operate a group instead of just operating the
relays directly?
When you want the switch to operate more :A
than 8 relays, the system will require you to make
them into a group.
How do you toggle a group on and off using a :Q
single switch button?
You can’t. Groups cannot be toggled. If you :A
want to turn more than 8 relays on and off
with a switch, you need to use two buttons and
two groups: one MOMENTARY On and one
MOMENTARY OFF.
What kind of group would you normally NOT :Q
assign to a momentary switch?
You normally do NOT assign any of the maintain-:A
type groups (MAINTAIN, MAINTAIN+TIMER,
MAINTAIN+BLINK) to a switch. The reason for
this is that switch buttons turn maintain groups
ON when the button is held down and OFF
when the button is released.
Having to hold the button down to keep lights
on is not generally useful!
If you are having a photocell control more than :Q
8 relays, what type of group would you assign to
the photocell?
You would normally use a maintain-type group. :A
Remember that only maintain-type groups can
be turned on AND off. If you want the photocell
to turn lights ON when it is dark and OFF when
it is bright, the easiest way is to use a maintain
group.
When would you use a momentary-type group :Q
with a photocell?
When you only want the photocell to turn the :A
relays OFF, or only want it to turn relays ON.
Even when using a schedule to turn the lights
off (for example at 11:00pm), one would usually
program the Photocell as “Maintain”. This ensures
the lights turn off at dawn in the event that an
override “ON” command switched the lights on
during the night.
