EHS Cascade Controller

Designed to enhance the performance of multiple heat pumps operating simultaneously to maximize system efficiency¹. With the capacity to control up to 8 EHS² units, the system provides increased flexibility to adapt to heating and Domestic Hot Water (DHW) demands. It continuously monitors the hot water demand and adjusts the operation of the units accordingly. The Controller ensures that the correct number of units are running based on needs, preventing under use or overloading.It starts the unit with the lowest runtime, and stops the unit with the highest. This helps balance usage and optimize efficiency across the system by keeping the units at their high-performance range. With a capacity of up to 128kW, the EHS Cascade Controller offers solutions for heating, cooling and DHW, while being able to control two independent heating zones. It can integrate with other heat sources enabling hybrid operation for best energy use.The Cascade Controller supports Modbus for integration with other control systems and is compatible with EHS Cloud³ and SmartThings⁴ on firmware version ’25.1Q.
