The High Temperature Control is a safety shutoff device engineered for Mr.Steam CT Day Spa and CU Commercial Steam Generator systems, providing critical over-temperature protection and alarm function. If steam room temperature rises above its 120°F set point, the device sounds an alarm and automatically disconnects the heating source, preventing dangerous overheating in the enclosure. Following activation, the device and steam generator can only be reset by an attendant once the steam room has cooled below the set point, adding a deliberate safeguard against premature restart. This high limit function is required by code in many commercial installations, making it an essential rather than optional safety component for compliant steam room operation. Compact and lightweight at just 1 lb., this genuine Mr.Steam replacement part restores proper high-temperature shutoff protection after a failed or malfunctioning unit, helping facility operators maintain a safe, code-compliant bathing environment for every session.
