As part of its Total Comfort Control solution for enhanced indoor air quality (IAQ), Bosch Thermotechnology has introduced customizable thermostats that communicate directly with geothermal heat pumps and other HVAC systems in home applications. Bosch’s new thermostats have been designed for application versatility: they not only can work with Bosch’s residential Greensource Series geothermal heat pumps, they can also be used with other home HVAC system including split system air conditioners, other heat pumps, gas furnaces and even dual fuel / hybrid equipment. They can be used with gas, electric and oil-fired systems and can be added-on or retrofitted to existing geothermal heat pumps or other HVAC systems. Bosch communicating thermostats enable the homeowner to save on energy bills. The Bosch thermostat can even send out alerts about the unit’s operation, notifications of a dirty filter, to change humidifier pad, change high-efficiency UV (ultraviolet) filters or PCO (photo-catalytic oxidizer), and unit operating efficiency notification. The thermostat has a built-in permanent backup battery – if the thermostat has a fault, it can operate the unit in safe mode, thus preventing the home from freezing in winter or overheating in summer. The Bosch communicating thermostat can display alerts at the thermostat, so the customer can readily view how their heating and cooling system is operating. With touchscreen control at one’s fingertips, Bosch communicating thermostats take the guess-work out of when to perform maintenance on heating and cooling equipment and any Bosch IAQ accessories that may be part of the home comfort system. Bosch communicating thermostats are lead-fee and mercury-free and are available in touchscreen controlled formats. Both models come with digital displays and non-volatile memory capability, meaning that they do not lose information and pre-set programs during power outages.
