The CTI Mini-Max and Digital Signetic
Spa controls are designed to work with either 230 or 115 volt devices. The
following shows how to convert them from 115 to 230, simply switching the
common line for the concerned piece of equipment.
|
First thing to do is identify the pump connector. You
need to follow the white wire from the connector, all the way over to the left
side of the circuit board. It may be easiest to do this by cutting the nylon
tie wraps around the wire bundle.
|
This simply identifies the two sources of return power for
all of the devices in the spa control, the neutral and L1 Bus attachment
points. If a component runs on 115 volts, it's common line will be connected to
the neutral set. If it runs on 230, then it will be connected to the L1
side.
The neutral bus uses J9, J10, and J11 as identified on the
circuit board. The L1 bus uses J13, J14, and J15, located just below the
neutral bus.
|
On the left side of the circuit board is where the pump
common line ties into. It is going to be the largest white wire in this case.
You will need to at least cut the nylon tie wraps around this end of the
harness to gain access to the quick disconnects.
|
Now for the easy part. Simply remove the common line from
the neutral bus, and re-attach it to the L1 bus, as shown in the following
image.
|
Simply attach the line to J13, J14, or J15. Note this
procedure is the same for the blower and ozonator plug.... but only if they're
running on 230 volt power!
To change any other devices, simply select the appropriate
common line for the associated component plug. To change one from 230 to 115
volts, simply reverse the procedure. Be careful though, you could destroy a 115
volt device by the misapplication of 230 volt power to it! |
