R02 Series

The R02 series consists of control relay boards that are designed for use with fan coil systems having auxiliary back-up heat or any other system that requires thermostat inputs. The R02 series will operate 2 or 4 pipe fan coil systems. The system switching is done through relay contact switching. The input is line voltage and output to the thermostat is low voltage, 24 VAC. There are external low voltage circuits available. The relay board transformer is rated to handle external low voltage loads with total VA consumption of 16VA at 24 VAC.
