Product HighlightsThe ecobee Energy Management System Si (EMS Si) is the newest technology designed for the commercial market. It is ideal in applications where a simple programmable thermostat does not provide adequate controls and functionality and a full-scale building automation system is too complex and expensive. The ecobee EMS Si is simple to install and program, reduces operating costs, and delivers increased energy conservation. The EMS Web Portal allows you to remotely monitor, identify, analyze and troubleshoot performance issues; manage the temperature and operational settings from a central location; and take action without having to send a technician on-site.
- Wi-Fi enabled, and accessible through the internet via ecobee's web portal interface.
- Supports multi-stage systems (up to 2 heat / 2 cool)
- 2 dry contact inputs that can be programmed to turn off the AC, adjust the heat and or cool set temperatures, switch the system to occupied or unoccupied mode, or activate an accessory relay.
- 2.5" (diagonal) full color LCD display
