iS4 Spa-Side Remote Control
The iS4 Spa-Side Control can be used with the Pentair® IntelliTouch®, EasyTouch® Control Systems and the Compool® CP series Control Systems to provide remote switching of four control circuits from the spa location. It is typically used for activating spa circulation and three auxiliary pieces of equipment (such as lights, jet pump, air blower, etc.). One iS4 spa-side control can be installed per control system. It is possible to install two iS4 remotes on a single control system, however, the two iS4 remotes will mirror each other in functionality.[1]
Most of the time, the remotes are the problem, but the main board can also be a problem.. The remote is nothing more than a few momentary buttons that pass a ground or +5 VDC through one of the buttons to an IC chip that responds.. If the chip is bad, the buttons will not work. You can just use a jumper wire to see if the problem is the remote or the board. Another possible problem could be that you have lost the program/memory that tells the system what each button is supposed to do.
Here is the schematic for the Pentair remote.
