Set Number of MWT Channels (Zone Control Only)
If the Control Method is set to Scene Control, refer to Set Options – Scene Control.
The number of MWT channels may be set from 0 to 4. If the GRX-CCO-8 will not be controlling any
MWTs, set the number of channels to 0.
Set the number of channels using switches 1, 2, and 3 on the OPTIONS switch (see diagram

The MWT channel(s) may be set to have Open and Close outputs, or Open, Stop and Close out-
puts. Refer to the manufacturer's MWT Controller Installation Guide to determine how many out-
puts per MWT channel are appropriate.

Outputs not used as MWT channels may be controlled as individual outputs (e.g., if the GRX-
CCO-8 is set to have 2 channels of MWT controllers, and each channel has 2 outputs, then
there will be 4 outputs left over to act as individual outputs). The output will be closed when the
GRX Control Unit zone to which it is assigned has an intensity greater than zero.
