Three-zone control from Bosch Thermotechnology
Bosch Thermotechnology’s Comfort Zone Manager 100 is a three-zone control expandable up to eight zones and can activate either circulators or zone valves. It monitors changes in room temperature and adjusts the boiler’s water temperature and firing rate to reduce energy use. The control operates the heating system at the lowest possible input in order to reduce room temperature swings. No programming is required.
