Heating/cooling circuit controller 2-fold 0-10V man REG - KNX Heating actuator for home automatio... – ABB – 2CDG110219R0011 – 4016779011624: Heating/cooling circuit controller 2-fold 0-10V man REG HCC/S2.1.2.1 bus system KNX, other bus systems without, mounting type REG, width in modular units 8, with bus coupling, control variable constant, valve protection function, manual switching, number of binary inputs 6 , max. switching current (resistive load) 5A, number of outputs 4, max. output current 5A, switching voltage 230... 230V, degree of protection (IP) IP20, min. depth of device box 64.5mm, for controlling a heating or cooling circuit . The device has 2 channels, each with an analog output for controlling the 3-way mixer valve (0 to 10 V) of a heating or cooling circuit. The device also has a relay output (5 A) for switching the circulation pump. The status of the pump can be monitored via 3 binary signal inputs (via potential-free contacts) and this feedback can be included in the control of the pump. The flow and return temperatures are measured and used by the integrated controller to calculate the valve control value. The setpoint is received via the KNX bus. Channel bundling makes it possible to control systems with double pumps. The HCC/S 2.1.2.1 has an easy-to-use on-site control. The ABB i-bus tool can be used for extended diagnostic functions and improved commissioning.
