e4Smart Digital Thermostat
Model e527
GENERAL DESCRIPTION:
The e4 527 Smart Digital Thermostat is a powerful, multi-purpose
device. Its core is a DDC illuminated thermostat designed to
control virtually any fan coil unit or packaged terminal air
conditioner found in hotel guestrooms. Its modularity allows the
e527 to connect to and operate various INNCOM HVAC
equipment control modules, such as X05 or X06. The control
module, powered from 24 VAC or 110-277 VAC, provides
the required 12 VDC power to the e527.
Connected to INNCOM’s low-cost CINET with a pair of low voltage
wires, an even more powerful, centrally controlled
EMS package is created. Further, the e4 is readily
expandable to include functionality such as humidity
control, outside temperature display, minibar access
reporting, occupancy reporting to housekeeping,
automatic control of lights, and much more.
Thanks to its compact design, the e527 fits neatly into a
British standard sized electrical box. An optional back
plate makes the device equally suitable for an American
standard sized electrical box.

OPERATION:
In its most basic form, the e4 functions as a high quality
DDC thermostat, automatically adjusting fan speeds and valves to
achieve set temperature. In its EMS mode, the e4 receives
inputs from the PIR motion detector and INNCOM's wireless
door switch. When it determines that the guestroom is
unoccupied, the temperature is allowed to drift up or down
within a programmable setback band in order to save energy.
When the e4 becomes part of a centrally controlled system
connected to INNCOM's CINET, substantial additional energy savings
are achieved by using a broader setback band when the guestroom
is unrented.
In addition, the e4 may use its control assembly to receive
inputs from monitorable points in the room, such as a balcony
door, minibar, or smoke detector.
INSTALLATION:
The e4 is wired as a low voltage wall thermostat with 3 wires.
Total installation time for both the e4 and INNCOM’s wireless
door switch is typically less than 45 minutes per room. Adding
the CINET for central control requires additional time.
