We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

Replace the module that matches your system

Check the label, wiring and UKU generation against the installed main module before ordering. Have the fault diagnosed before replacing control hardware.

Starting a new sauna?

A complete UKU package is the better starting point for a new heater installation. The package supplies the coordinated control components; this listing is a single replacement module.

Installation

A qualified electrician must isolate power and follow the exact control manual. Do not assume interchangeability with UKU 4.2 or another main-module revision.
