This HB series was intended to be used as a 2 circuit thermostat controlling a circulation pump and a Fan on a hydronic coil heating system, though it could have other uses where you need a 2 circuit control with a 1 minute delay on the 2Nd circuit. This control will solve the historic problem of using a standard 22 amp bi-metal heating thermostat on a hydronic system which require high amp loads to be accurate. Without a load they will not shut off the circulating hot water when not needed. This control positively controls both circuits creating energy savings, superior control and comfortable living spaces.
