T8-S / T8-X Topside Installation
7
Topside Installation Preparation
The T8-S / T8-X topside control requires three 2-1/4” holes to be cut out
of the shell of the hot tub it is to be installed into. Using a 2-1/4” hole saw,
three holes will need to be drilled in a straight line, with the center of each
hole spaced 1-5/8” from the center of the previous hole, as shown:
Topside Control Installation
Once ready to install, plug one end of the topside cable into the back of the
T8 topside control, and snake the topside cable through the cutout in the
spa’s shell and down to the control box. Then plug the opposite end of the
topside cable into the topside receptacle on the control box.
Simply affix the topside to the hot tub by peeling off the paper over the
adhesive back of the topside and press it firmly into place, slowly pressing
all around the perimeter of the topside firmly to assure a firm bond.
NOTE: Do NOT connect/disconnect the T8-S/T8-X topside while the
control box is powered. Always make sure the power is shut off at the
breaker before removing/installing a topside, as to avoid damaging the
electronics.

The T8-S / T8-X Topside
You will be using the T8-S / T8-X topside to operate your United Spa
Controls C5 Series control box. The T8-X is pictured below, with the
descriptions of the items that will be referenced throughout this user’s
guide. The difference between the T8-S and the T8-X is that the T8-X has
an ‘Jets-3’ button, to operate a 3rd booster pump or air blower.
* T8-X Only: There is no Jets-3 Button on T8-S Topsides.

Using The T8-S / T8-X Topside
9
Using The T8-S / T8-X Topside
The T8-S / T8-X topside uses United Spa Controls’
technology. This hybrid switching technology marries the
satisfaction of having a physical button to press, with the longevity and
reliability of touch-panel switching system with no moving parts to break
down over time.
If your button presses are not registering, make sure that you are pushing
the raised buttons completely flat against the panel, and that you are
waiting a second between button presses.
Upon Power-Up
Whenever the T8 topside is powered on, the unit will briefly flash between
‘T8-S’ or ‘T8-X’ and the current software version by showing a ‘V’ followed
by a number (Example: ‘V 03’) while it starts up. All configurable settings
are saved to permanent memory, the only thing that needs to be set upon
power-up of a T8-S or T8-X topside that has already been configured
previously is the current time (it will default to 12 AM upon power-up).
Checking Software Version After Power-up
The software version can be accessed after initial power-up by simply
pressing the Menu button (Display will read ‘MENU’), followed by pressing
the Light button. The display will then show either ‘S’ or ‘X’ depending on
the topside’s decal setting, followed by ‘-’ and the software version number.
For example, a T8-X with software version 03 would display ‘X-03’.
