Bosch Thermotechnology Corp. just announced changes in two controllers for the residential Greenstar boiler line. The Bosch FW200 weather compensating controller will be phased out once inventory is depleted, currently expected at the end of 2019. The Bosch CRC200 thermostat manufactured December 2019 and later will now have outdoor reset capability in addition to all its current features. To enable this functionality of the controller, an outdoor temperature sensor is required (sold separately). All Greenstar wall boiler models that include a CRC200 in the package will also have the updated controller implemented in production starting in December 2019.
