Bosch Thermotechnology Upgrades Geothermal Heat Pump Model

Bosch Thermotechnology has introduced its upgraded model in the Greensource CDi series: the Bosch SM Rev C Geothermal Heat Pump, featuring the Heat Pump Control (HPC) microprocessor, which can communicate with the Bosch EasyStart app.

Bosch redesigned its SM model with a user interface and electronics controls to make it easier for contractors to communicate with the unit.

With the Bosch EasyStart app, technicians no longer need to open the physical unit to configure it using DIP switches and/or cut resistors. They can commission the unit by configuring up to 24 optional settings for customizable comfort, as well as view the real-time status of components and system temperatures to aid in start-up, troubleshooting and diagnostics.

The SM now comes with eight thermistors (temperature sensors) that are strategically placed within the SM unit cabinet. The thermistors relay temperature readouts such as entering water, leaving water, return air, discharge air, discharge refrigeration, freeze evaporate, freeze coaxial, and domestic water to the HPC and EasyStart app. For unit communication, the local Wireless Interface Module allows for remote install and monitoring within a 20-foot unobstructed radius.

“Bosch listened to its contractor’s pain points and addressed them head on with the upgraded SM Rev C and the Bosch EasyStart app,” says Andrew Archambault, senior product manager at Bosch Thermotechnology. “With the app, technicians no longer have to crawl into tight attics, walk over rafters or balance on ladders to install or service a unit. With just the push of a button on the unit they can come out and have the communication access they need to get the job done safely and efficiently.”

For improved and in-depth diagnostics, the system tracks the latest 70 faults and highlights the full history with current faults and component correlation. Additionally, contractors can now set the system to run an automatic troubleshooting sequence using Test Mode.

The SM Rev C was awarded the ENERGY STAR Most Efficient 2019 label for its technology that delivers cutting edge energy efficiency. The unit also qualifies for tax credits and has low operating costs, saving the consumer up to 70 percent on utility bills. With sound levels as low as 52 dB, it offers quiet operation while improving indoor air quality and comfort.

The Bosch EasyStart app is available for Windows laptops, iOS tablets in the App Store or Android tablets in Google Play Store.
