The e4 Smart Digital Thermostat Model E527 is member of INNCOM's Integrated Room Automation System (IRAS). It is a powerful, multi-purpose controller. Its core is a Direct Digital Control (DDC) processor capable of controlling virtually any fan coil unit, heat pump or packaged terminal air conditioner found in guestrooms. It includes an easy to read illuminated Liquid Crystal Display and its compact design allows it to be installed in British and American standard size electrical boxes.
The Model E527 can be expanded to include functionality such as humidity control, outside temperature display, minibar access reporting, occupancy reporting to housekeeping, automatic control of lights and the patent pending ecoMODE green button. It can be used in a stand-alone application, integrated with the IRAS or in a centrally controlled network.
The Model E527 is designed to be intuitive for guest use. The buttons can be used to turn the unit to AUTO or turn it OFF. The FAN button lets the user select among the available fan speeds and the DISPLAY button lets the user toggle between the set temperature and the actual or outside room temperature. The side-mounted buttons allow the user to increase or decrease the set temperature. The recessed button allows the user to toggle between F and C scales. The user may also elect to participate in the property's sustainability practices by touching the ecoMODE touch surface.
The Model E527 is a multi-capability DDC controller. When used as an HVAC controller or thermostat it will automatically adjust fan speeds and valves or compressor run time to achieve set temperature. As the key node in an Energy Management System (EMS) mode, it receives inputs from a 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 is allowed to drift 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.
When it is connected to INNCOM's centrally controlled system additional energy savings are achieved by using a broader setback band when the guestroom is un-rented. It can also apply wider temperature set-back bands when the room is in hibernation during off-season periods. The Model E527 can also control lamps equipped with the INNCOM L206 or L208 Lamp Control Modules through external diffused IR transceivers or other devices connected to the S5 bus or equipped to receive wireless signals. In addition, it can also receive inputs from other points in the room such as a balcony door, minibar or smoke detector and transmit their status to the central server.
