The new Remote Room Controller Smart Thermostat from Bosch Thermotechnology uses a home WiFi connection to allow space heating and domestic hot water to be monitored and adjusted from any compatible smartphone or tablet. It can adjust the flow temperature of the boiler to the minimum level required to enhance condensing operation, yet still maintain the required room comfort level — by utilizing room feedback or outdoor reset (weather compensation). Up to four mobile devices can be connected to the RRC Smart Thermostat to detect when occupants are at home.
