Installation
Location
Select a location about 1.5m (5ft) above the oor and with
good air circulation at average temperature. Do not mount
the thermostat where it may be aected by:
• Drafts or dead spots behind doors or in corners
• Hot or cold air from ducts
• Radiant heat from sun or appliances
• Pipes or chimneys
• Unheated or uncooled areas behind the thermostat
• RF sources or transmitters
For accurate presence detection using the built-in PIR sen-
sor, consider the sensor’s view angle, range characteristics
and thermostat mounting position.
Mounting
The INTEREL EOS Thermostat is designed to be surface
mounted, and therefore can be installed in almost any sce-
nario found in a hotel guestroom. Typically, the EOS ther-
mostat will be mounted on a (4x4) double-gang junction
box. If mounted on a single-gang junction box, the 24 Vac
power or 100–277 Vac power and signal wires connecting
CN2 to the HVAC equipment must reside in the single-gang
box, and the low voltage signal wires connected to CN1 re-
side on the left side overlapping the wall area. A low voltage
mud ring, or low voltage caddy may be used for mounting
the 24V AC EOS Thermostat.
Before beginning work, ensure that the supply power
(24 Vac or 100-277 Vac) is turned o and secured. If an
existing thermostat is being replaced, remove the ther-
mostat and note the function of each wire if not already
documented. Position the EOS Metal Wall Bracket with
raised arrows pointing UP and mount it to the junction
box using the (4) provided screws. The installation area
behind the bracket must be at and free from debris to
allow the Metal Wall Bracket to sit at on the wall. Adjust
the bracket position to be level before fully tightening
the screws. Do not over tighten the screws, which may
result in a loose connection to the EOS Thermostat.
Remove the CN1 and CN2 connectors from the back of
the thermostat by prying them out gently with a at
head screwdriver. Then prepare the power and control
wiring coming from the HVAC equipment and connect
the appropriate wires to their respective terminals on
the CN1 and CN2 connectors (refer to the property and
HVAC equipment wiring diagrams).
Insert the CN1 and CN2 connectors back into EOS, veri-
fying that they are fully seated for a secure connection.
When mixed voltages are used on the CN1 and CN2
connectors, a voltage separator must be installed per
local electrical code regulations. Line voltage must re-
side in the right side of the junction box and low volt-
age must reside in the left side of the junction box.
Installation Instructions
CAUTION: Disconnect the power supply before installation to pre-
vent electrical shock or equipment damage. All wiring must comply
with local codes and ordinances.
• Read the instructions carefully. Failure to follow them could damage the product or create a hazard.
• Check the ratings given in the EOS datasheet and on the product to ensure the product is suitably rated
for the application.
• The installer must be a trained, experienced HVAC technician.
• After installation is complete, check product operation as indicated in the instructions.

The thermostat slides downwards and locks onto the metal
mounting bracket utilizing the six hooks on the metal brack-
et. Position the thermostat just above the mounting bracket,
press towards the wall and slide it down, securing it to the
bracket. The thermostat will snap into place on the metal
wall bracket and feel securely fashioned if installed properly.
To lock the thermostat to the wall, use the large at head
screwdriver to turn the lock pawl on the bottom side of the
thermostat counterclockwise. Test the closure by gently lift-
ing the thermostat upwards.
Apply power to the EOS Thermostat by closing the applica-
ble supply breaker. Verify that the EOS Thermostat powers up.
The OLED display should show INTEREL and 3 dots.
Pinch the protective lm tab tab on the top right of the ther-
mostat display and pull straight out to slowly peel the lm.
Remove the lm slowly to reduce the risk of tearing it and
leaving residue on the thermostat display.

• Always power o the system before cleaning.
• Always use an anti-static wristband or other professional grounding devices.
• Never spray cleaning uids directly onto components. Always spray the cleaner onto a soft cloth then wipe.
• Do not allow any cleaner to run or drip near circuit boards, or near seams on device casings.
• Never allow circuits or electronics to become damp or wet.
• Some cleaning solvents can damage components. In most cases, water will work just as well.
• Do not attempt to clean any electronic components such as circuit boards or wire connection terminals.
• Hands shall not be wet when plugging and unplugging exible cords and connected equipment.
• Avoid the use of alkaline solution to clean the glass. Do not spray solvent directly onto glass face.
• Always use a soft cloth to wipe the glass when using solvent cleaner.
Cleaning procedures
Cleaning control panels shall start by wiping o any dust or debris with a clean and
dry microber cloth. Avoid direct spraying of cleaning uids onto the control panels or
electrical wiring.

• Explosions can be caused when
electricity provides a source of ignition
for an explosive mixture in the
atmosphere.
• Fires are caused by overloading
a circuit or appliance or by current
owing through high resistance due to
faulty wiring, setting re to insulation
and surrounding materials.
• Electric shock/electrocution occurs
when current ows through the body
damaging the body.
• Electrical burns are caused by arc
blast or hot conductors.
• Indirect falls from ladders, scaolds, or
other walking and working surfaces.
General Precautions Electrical Hazards
• Disconnect any devices from RCU Bus and
de-energize power supply prior to installation.
Failure to abide by the installation and operating
instructions may result in re and other hazards
• Comply with the terminal
specications as approved in the device pinouts as
per datasheet and dened on approved wiring
schematics Modication of electrical leads or
improper termination than where it is supposed to
be connected can cause damage to the unit.
• Device terminations shall be legibly labeled or
marked to indicate its purpose.
• Always follow the correct input/output
connections to the device based on the approved
design.
• Device should not be terminated with any high
voltage wiring. Do not mix the use of low voltage
and high voltage cable in the backbox and/or
conduit to pull wires. Wire run for Glass Panels and
Thermostat should be separate from any lighting
or HVAC loads.
• Electrical wires entering boxes,
cabinets, or ttings must be protected from
abrasion.
• All devices and all associated test leads, cables,
power cords, and connectors shall be visually
inspected for external defects and damage before
the equipment is used.
