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.
