The Fenix FX30 control is designed for use with compatible Harvia Club, Spirit, Cilindro and Virta electric sauna heaters that accept FX series controls. It supports both single phase and three phase wiring up to the listed heater outputs. For larger commercial loads a separate Harvia power extension unit may be required.
Mount the glass touch panel on a dry wall surface near the sauna entrance or in an adjacent room and locate the power unit in a serviceable area according to Harvia clearances. All high voltage connections and low voltage signal wiring must follow the installation manual and local electrical code. Harvia strongly recommends installation by a licensed electrician familiar with sauna systems.
