The Bosch TSTAT2 Protankless Wireless Remote, part number TSTAT2, is a wireless temperature control remote designed for use with compatible Bosch Protankless and Therm series tankless gas water heaters. This remote allows the user to adjust the output water temperature from a convenient location within the home without direct access to the heater unit. It provides a practical solution for households where the water heater is installed in a remote or difficult-to-access location.
The TSTAT2 operates over a radio frequency signal and communicates with a receiver circuit board installed inside the heater's control panel. Once paired, the remote delivers reliable temperature adjustment capability from distances within its rated operational range. A priority lock function prevents temperature changes while the water heater is actively in use, maintaining consistent output during active draw cycles.
What's Included: TSTAT2 wireless remote transmitter unit, receiver circuit board for installation inside the heater control panel, connector wire, and two AA batteries.
Installation Limits: Installation requires opening the heater control panel to seat and connect the receiver circuit board to the unit's main control board. Older 635ES and 635ESO models require additional disassembly of the electrical control board. The remote does not provide reset functionality and cannot be used to reset the heater.
Compatibility: Compatible with Bosch Protankless and Therm series models including 635ES, 635ESO, 715ES, C800ES, C920ES, C920ESC, C830ES, C940ES, C940ESO, C950ES, C1050ES, C1210ES, C1210ESC, Integra 500, and Evolution 500 tankless gas water heaters.
