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.
