WSV Series
DDC Controller for Water Source Heat Pumps (WSV Series)
The DDC Controller is a factory-engineered control solution designed for WSV Series water source heat pumps. It provides reliable, intelligent control of all major system components, including the compressor, fan, and reversing valve.
With built-in BACnet® and Modbus communication, the controller enables seamless integration with building automation systems (BAS) for real-time monitoring, diagnostics, and control. It can operate with a standard thermostat or as part of a fully networked system.
Designed for commercial applications, the DDC Controller enhances system performance, protection, and serviceability through advanced control logic, integrated safeties, and onboard diagnostics.
