Description
The MRC Digital Thermostat is an expandable
multi-purpose, high-quality Direct Digital
Control (DDC) illuminated thermostat
designed to control virtually any Fan Coil Unit
(FCU) or Packaged Terminal Air Conditioning
(PTAC) found in hotel guestrooms. The MRC
comes standard with five relays, and can be
equipped with an on-board Infrared (IR)
transceiver and Passive Infrared (PIR)
occupancy sensor. Coupled with a magnetic
door switch (wired or wireless) the MRC
becomes the brain of a highly effective Energy
Management System (EMS) for guestroom s.
When connected to a Central Interface
MRC Digital Thermostat
with On-Board PIR
Network (CINET) with a pair of low voltage
wires, a centrally controlled EMS package is
created. The MRC is readily expandable to
include functionality such as humidity control,
outside temperature display, mini-bar access
reporting, occupancy reporting to
housekeeping, automatic control of lights, and
much more. Use of infrared or low voltage
wiring enables remote control of lights,
occupancy reporting, and other functions.

Features
• central control, with multiple services
integrated on a common platform, provides
fully automated guest room control and a
communication system for the lodging
industry, with the ability to tie together the
guest rooms and other systems within the
hotel, including the Property Management
and Building Automation System
• Passive Infrared (PIR) and entry door
access detection provides reliable and
automatic energy management by
activating programmable temperature
setbacks when the guestroom is
unoccupied
• exceptionally versatile lighting controls
designed specifically for hotel guestrooms
allow guests to control their lighting
environment remotely —and, the controls
can be programmed to turn on one or more
selected lights when guests first enter the
room, after check-in, creating a warm,
welcoming guest room ambiance
• Infrared (IR) technology provides areas with
high labor costs, or restrictive electrical
codes, practically wireless installation with
the unique IR capability
• “Do-Not-Disturb/Make-Up-Room and Door
Chime” System add to the guests’
amenities and eliminates the use of oldfashioned, outdated hanging cards and the
need for staff to knock or yell through the
door to guests — guests can effortlessly
interact with hotel staff and services.

provides hotel operational efficiency and
greater guest security when the door locks
are controlled via this wireless, real-time,
on-line lock control system
