The Bosch Control Smart Room Thermostat works with compatible Bosch and Buderus condensing boilers and allows the user to control both heating and hot water settings for greater energy savings. Energy Management System technology matches the boiler output with user demand, and the programmable thermostat comes with an integrated temperature sensor and remote boiler control, all in one device. Users will appreciate the easy-to-use touchscreen, plus an iPhone- and Android-compatible app for at-a-glance information and adjustment. The maker says Bosch Control is the only thermostat of its type that can adjust the flow temperature of the boiler to the minimum level required to enhance condensing operation, while still maintaining room comfort. List price is around $225.
