Industrial TUH-1 Thermostat

Raywall TUH-1 is a single-pole, line-voltage thermostat kit designed for Raywall UH-series horizontal unit heaters. The 25 Amp SPST control switches the heater circuit on and off to hold spaces at a user-set temperature within a 40°F to 110°F range, compatible with 125–250V electrical service. Sold as a field-installed accessory, the TUH-1 is wired in-line with the unit heater’s electrical circuit and paired with UH-series equipment to deliver straightforward temperature control in commercial and industrial applications such as warehouses, loading docks, and workshops where Raywall heaters are used. The kit is specifically built for line-voltage operation and complements Raywall’s thermostatic control lineup, providing a practical option when an external thermostat is preferred or required by installation constraints. For proper installation, follow local electrical codes and refer to the UH-series installation guidelines to ensure safe, reliable operation.
