Applications
Thermostat Fan Speed Control For Energy Saving
This application note uses the HotelTech thermostat to demonstrate how to connect a thermostat to control an electronically commutated (EC) motor-driven fan using the ECM-4Spd-PRO controller
EC motor efficiency is often above 90%, allowing EC fans to consume up to 70% less energy, when compared to conventional fans.

How to add Overheat Protection for SSR and low air flow in electric heat control
Modbus/bacnet integration
A BACnet building automation system may include HVAC, lighting, and life safety subsystems. The EVO/ECM-Modbus RTU fan system can now be integrated to a BACnet building automation network through Modbus to BACnet gateways to operate in response to other subsystems. The gateway directs the data flow back and forth between BACnet’s subsystems and the Modbus network.
The EVO/ECM-BACnet-Modebus library provides the mapping files for the Control Solutions B1-10x Babel Buster SPX gateway to translate between the EVO/ECM-Modbus RTU registers and the BACnet objects. See the intgration section in the Application Guide for detail.
EVO/™ECM-4Spd Control Unit
Application for VAV with Staged Electric Heat
The EVO/ECM-4Spd control can be applied to most EC fan powered VAV terminals with staged electric heat.
The application provides:
Energy Savings.
Improved Ventilation.
Improved Comfort.
Application for variable VAV terminal fans
VAV systems were developed in response to the early 1970's energy crisis. These systems reduced energy usage, sometimes at the expense of comfort. But today's building owners want the VAV system's economy without sacrificing comfort.
Many applications require a VAV terminal fan to achieve satisfactory comfort. Recent advances in air moving motor technology allow efficient variable speed operation of these fans.
Variable speed fans may be applied to improve comfort and save energy.
