that they have light by pushing any button with a rap-
idly blinking LED . This is the indication that the lights
are in Blink Time OUT .
: Q Where are the two locations on the DTC that a relay
timer can be viewed or programmed?
: A USER MENU >GROUP LOADS >TAB to GROUP >
ENTER to select >TAB to MAINTAIN+TIMER or
MAINTAIN+BLINK >ENTER to select >
USER MENU >SETUP MENU >SYSTEM SETUP
MENU >RESTRICTED (PASSCODE 900001) >RE-

: Q You create a new MAINTAIN group or add new re-
lays to an existing MAINTAIN group and EXIT . Upon
re-entering the group, you notice it has changed itself
into MAINTAIN+TIMER . Why?
: A One or more of the relays in the group are also in
another MAINTAIN+TIMER or MAINTAIN+BLINK
group which has assigned it or them a timer value .
Since the timer value is written into the relay prop-
erties, it is carried over into the new MAINTAIN
group .
: Q What does MAINTAIN mean in reference to a wall
switch?
: A It means that the switch concerned is a contact clo-
sure switch like an ordinary wall switch . When one
flips the switch UP the contacts close and stay closed
and the lights come ON . (They are MAINTAINED
that way . ) When one flips the switch down the con-
tacts open and the lights go off . Note that both making
the circuit and breaking the circuit (from the switch
to the contact input) causes the relay(s) to react .
: Q What does MOMENTARY mean in reference to a
switch?
: A It means that it is expecting a pulse as would be re-
ceived from a push button . The command is executed
on contact closure . The contact opening does nothing .
: Q How do you find out which group(s) a relay is in?
: A Look in the "What & When Menu": SETUP MENU
>SYSTEM SETUP MENU >WHAT AND WHEN?
>WHAT CONTROLS RELAYS . Select the relay and
press ENTER . Any groups that the relay is in will be
displayed .
: Q How do you find out what is turning a group off or
on?
: A Look in the "What & When Menu": SETUP >SYS-
TEM SETUP >WHAT AND WHEN? >WHAT
CONTROLS GROUPS . Select the group and press
ENTER . Any schedules, photocells or switches that
control that group will be displayed .
: Q How do you manually turn on a group using the clock
interface?
: A Go to the "group loads" screen, highlight the group:
1 . For a MOMENTARY ON group SCROLL UP to
turn the relays in that group on,
2 . For a MOMENTARY OFF group SCROLL UP to
turn the relays in that group off,
3 . For a MOMENTARY MIXED group SCROLL UP
to control the relays per the ON and OFF pro-
gramming within that group,
4 . For any MAINTAIN group, SCROLL UP to turn
the group on and SCROLL DOWN to turn the
group off .
: Q What do you do to synch up the relays in a group,
when some of them are on and some are off?
: A Go to the "group loads" screen and turn on the group
again using the SCROLL UP button . If the group is
already "ON" scrolling up will re-reiterate the "ON"
command .
: Q How do you get rid of a group you don't want to
use anymore?
: A Go to the "GROUP LOADS" screen, highlight the
group and press the DELETE button .
: Q What should you suspect is happening when you de-
lete a group but the relays still have a timer?
: A Those relays are in another MAINTAIN+TIMER or
MAINTAIN+BLINK group which is forcing a timer
onto them .
