The syntax for setting a special function is __ *
X?
# where __ is the function number and
X?
is the value.
To view a function’s setting, use __#, where __ is the function number. In the following table the values of
the
X?
variable are different for each command/function. These values are given in the rightmost column.

Delay times
Power on delay 1 *
X?
# WarmUp*
X?
0 = 0 seconds,
1 = 2 seconds,
2 = 4 seconds,
... in 2 second steps up to
150 = 300 seconds (5 minutes).
Example: 1*8# WarmUp*08 Example: set a 16 second power on delay.
Example: 1# WarmUp*023 Example: view the power on delay
setting.
Power off delay 2 *
X?
# CoolDown*
X?
0 = 0 seconds,
1 = 2 seconds,
2 = 4 seconds,... in 2 second
steps up to 150 = 300 seconds.
Example: 2*23# CoolDown*023 Example: set a 46 second power off
delay.
Relays
Relay 1 mode/timing 4 *
X?
# Rly1Tm*
X?
0 = toggle mode (press on/off),
1 = momentary, 1 second long,
2 = momentary, 2 seconds long,
3 = momentary, 3 seconds long.
Example: 4*3# Rly1Tm*3 Example: momentary, 3 sec. long.
Relay 2 mode/timing 5 *
X?
# Rly2Tm*
X?
0 = toggle mode (press on/off),
1 = momentary, 1 second long,
2 = momentary, 2 seconds long,
3 = momentary, 3 seconds long.
Example: 5*0# Rly2Tm*0 Example: set relay to toggle mode.
Relay 3 mode/timing 6 *
X?
# Rly3Tm*
X?
0 = toggle mode (press on/off),
1 = momentary, 1 second long,
2 = momentary, 2 seconds long,
3 = momentary, 3 seconds long.
Associate a button with relay 1 7 *
X?
# Rly1Mode*
X?
Cause a button to control a relay.
For a relay set to be normally closed:
0 = power-on.
1 = power-off.
2-7 = MLC input selection buttons 1-6.
8-27 = remote control module 1 buttons.
28-47 = remote control module 2 buttons.
48-67 = remote control module 3 buttons.
68-87 = remote control module 4 buttons.
For a relay set to be normally open,
add 128 to the above numbers.
128 = power-on (relay normally open).
...
196-215 = remote control module 4
buttons (relay normally open).
127 or 255 = not assigned.
Example: 7*1# Rly1Mode*1 Example: Relay 1 will toggle when
the Display Power button is pressed
for power-off .
