Product Name(s): EC-FCU-L;EC-HPU-L;EC-RTU-L;EC-UV-L
Product Description: The Easycontrols EC-FCU-L, EC-HPU-L, EC-RTU-L, EC-UV-L controllers use the LonWorks communication protocol and are LonMark certified using the following profile: -#8080 unit ventilator (EC-UV-L) -#8020 fan coil (EC-FCU-L) -#8051 heat pump (EC-HPU-L) -#8030 roof top (EC-RTU-L) These controllers can be configured through any LNS compliant software.
Product Application(s): The EC-FCU-L is designed to meet the requirements of two and four pipe heating and cooling fan coil units with different stages of heating/cooling. The EC-RTU-L is designed to meet the requirements of a rooftop unit application with or without an economizer. Including mechanical stages, modualting valves, and floating outputs. Can control up to 4 stages of heating/cooling. The EC-HPU-L is designed to work with all types of heat pump, including dual mode and water to refrigerant heat pumps. The EC-UV-L is designed for unit ventilator applications.
