CS_DN25 M PWM2 • Heating loop pump sets, mixed circuit

The CS_DN25 D PWM2 is a pump group with insulation and a mixed temperature for heating and cooling. The group is used in combination with the ETERA geothermal heat pump. The PWM pump is directly powered and controlled by the KSM controller in this heat pump.

• KRONOTERM

The CS_DN25 M PWM2 pump group is mounted on the collector to circulate the cold or hot water over a circuit with the mixed temperature of the heat pump water. There is a three-way valve as a mixing section in this group. Floors are usually provided with water that is mixed in temperature (less deep cooling and less high heating), whilst radiators or fan coil units are provided with water at the direct temperature. On the ETERA heat pump, one mixed/direct circuit and one direct circuit can be connected as standard and with the expansion card on the controller (KSM+ 2) two more mixed/direct circuits can be added. The CS_DN25 D PWM2 can easily be hydraulically connected to the HR_DN25-2/3/4VI collectors.
