Bosch TSTAT2 Remote Control for Bosch AquaStar 2700ES / 2400ES / 2400E / 2400EO / 250SX / 250SXO / 635ES Tankless Water heaters gives you the ability to remotely adjust the temperature of your Bosch Tankless Water Heater to a safe and comfortable level.
The TSTAT2 remote is particularly useful if you own a jacuzzi or hot tub that requires a hotter water temperature than you normally desire for regular shower use. Most people who own hot tubs want to fill them at a temperature that is higher than that normally used for comfortable showers. The TSTAT2 remote allows you to remotely raise the temperature when filling a hot tub and then drop the temperature back to a "normal" temperature -- usually between 105 and 112 degrees fahrenheit.
Please note that the electrical control of the Bosch AquaStar 2700ES / 2400ES / 2400E / 2400EO / 250SX / 250SXO / 635ES must be removed and opened in order to install the wireless receiver circuit board to enable the use of the TSTAT2 Wireless Remote Control.
The Bosch 2700ES and Bosch 2400ES tankless water heaters have been redesigned to make the installation of the wireless receiver circuit board much easier.
