e527 Datasheet
Overview
Like the larger e528, the compact, low profile e527 thermostat takes advantage of
component end-of-life to redesign hardware and produce a more efficient, lower cost
device. With onboard radio and RS485 connection and an added CDS light sensor, the
e527 maintains its position as an integral part of the INNCOM Integrated Room
Automation System (IRAS) and a property’s Energy Management System (EMS).

Features
In an EMS, the e527 controls room heating and cooling using occupancy data collected
from motion detectors and door switches and can be networked to the property’s
central management system. As an IRAS device, the e527 can communicate with
devices within a room and function as a room gateway device towards the mesh network.

Installation Requirements
The e527 must be located on a partitioning interior wall, approximately 5' (1.5 m) above the floor, in a site of
average temperature. It is important to ensure that the thermostat is located away from direct sunlight or radiant
heat, air discharge grilles, stairwells, outside doors, steam or water pipes, warm air stacks, unheated/uncooled
areas, or sources of electrical interference. The unit should not be placed on an outside wall or behind a door.

The e527 is designed to be mounted on a standard British-style single-gang electrical box. For use with an
American box, the e527 can be installed in an optional frame by means of two screws. Screws for attaching the
optional frame and mounting the e527 are included. The device is shipped with a clear clamshell dust cover.
