ABB i-bus® KNX
Heating, Ventilation and Air Conditioning

Heating/Cooling Circuit Controller, 2-fold, 0-10 V, MDRC
For the control of heating or cooling circuits. The device has 2 channels, each with an analog
output to control the mixing valve (0…10 V) of a heating or cooling circuit as well as a relay
output (5 A) to switch the pump of the circuit. Via 3 binary inputs it is possible to monitor
the status of the pump (via potential free contacts) and integrate these feedback into the
control of the pump. The flow and return flow temperature are measured and used for the
HCC/S 2.1.2.1 calculation of the control value for the valve output in the integrated controller. The set point
temperature is received via the KNX bus. By bundling both channels of the device it is also
possible to use it for double pump systems.

Heating/Cooling Circuit Controller, 2-fold, 3-point, MDRC
For the control of heating or cooling circuits. The device has 2 channels, each with two elec-
tronic outputs to control a motor-driven mixing valve (3-Point) of a heating or cooling circuit
as well as a relay output (5 A) to switch the pump of the circuit. Via 3 binary inputs it is possi-
ble to monitor the status of the pump (via potential free contacts) and integrate these feed-
back into the control of the pump. The flow and return flow temperature are measured and
HCC/S 2.2.1.1 used for the calculation of the control value for the valve output in the integrated controller.
The set point temperature is received via the KNX bus. By bundling both channels of the de-
vice it is also possible to use it for double pump systems.
