NOTE: Throughout the years we have sold these spa side controls to many spa distributors and spa manufacturers without a decal. They would supply their own decal on our Smart Touch controller. The spa side control is the same, however the decal may be different.
When you purchase this spa side control direct from us we can only provide a decal when purchased from Table (2) below.
Your original decal may not have the same color or the same number of buttons. Our decal exposes all the buttons of the spa side control whether your original decal supported them or not. All Top Side controllers functions are the same regardless of the decal.
It is just a decal and has no effect on the spa operation.
