The E528 provides temperature control, humidity monitoring, and motion detection for energy efficient management of the HVAC system.

The E528 series thermostats is the core of a highly effective EMS and the network gateway for other room control devices and third-party interfaces. Flexibly configured with on-board control relays, the e4 series provides efficient control, monitoring, reporting, and comfort for guestrooms. As the key node in an Energy Management System (EMS), it receives inputs from the PIR motion detector and the wired or wireless door switches to determine guestroom occupancy. During times when the room is rented but the guest is not present, the temperature may range up or down within a programmable setback band from the guest’s selected temperature. This results in energy savings with no impact on guest comfort.
