guidance to mount it in a neutral location. The cost of
poor thermostat placement is high, both in loss of
guest comfort and unnecessary energy costs. Follow
these guidelines to determine the appropriate
installation location for the thermostat:
7. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
8. It is recommended to keep the device at room
temperature for at least 24 hours before applying
power. This allows any condensation resulting from
low shipping/storage temperatures to evaporate
• Place thermostats away from windows to avoid
bathing the thermostat with solar radiation,
which invalidates the unit’s temperature
sensitivity.
9. After installation is complete, check product
operation as provided in these instructions.
• Never place thermostats on a wall where an
open bathroom or closet door will cover them.
A covered thermostat will not register the
correct room temperature
NOTE:
All wiring must agree with applicable codes,
ordinances, and regulations as specified in
installation wiring diagrams.
• Take care to place thermostats out of the
Direct line of air movement. A thermostat
mounted on a wall Directly across from HVAC
discharge vents will be surrounded by air that
quickly satisfies the thermostat’s guest
temperature setting, but not register the
room’s overall temperature.
Restricting Access to Network
Prevent unauthorized access to the network that the
thermostat uses. With any system, preventing physical
access to the network and equipment reduces the risk
of unauthorized interference. When using open
protocols care should be taken to ensure that the
physical network is protected from unauthorized
access.
• Avoid placing a thermostat on a wall near the
fan coil. This causes a waterfall effect of
heated or cooled air movement across the
thermostat which triggers the HVAC’s
Location
response to false room temperature readings.
Select a location about 1.5 m (5 ft.) above the floor with
good air circulation at average temperature. Do not
mount thermostat where it may be affected by
•
Beware of value engineering proposals during
construction; such as optimizing room wiring
to minimize cable runs between thermostats
and the HVAC placement. Although this type of
value engineering can save money, it often
results in higher energy use and compromised
guest comfort.
• Drafts or dead spots behind doors or in corners
• Hot or cold air from ducts
• Radiant heat from sun or appliances
• Concealed pipes or chimneys
• Unheated (un-cooled) areas behind the thermostat
5. Make sure:
• The thermostat is mounted on the wall with the
bottom of the unit about 4-5 feet from the
floor.
• If RF equipped, do not install near other RF
sources/transmitters.
• When the thermostat is equipped with PIR, consider
120° view angle, range characteristics, and mounting
position for proper coverage.
•
The unit is level
• The manufacturer’s installation instructions
are followed.
Mounting
YES
INNCOM’s DDC thermostats typically mount on a
standard double-gang (4 x 4) junction box. If mounted
on a single-gang box, the left side (display side) of the
D1-528 thermostat overlaps the wall area to the left of
the junction box. A low-voltage mounting plate, mud
ring, or low-voltage caddy may be used for mounting 24
volt applications.
NO
NO
4 feet
(1.2 meter)
NO
6. Read instructions carefully. Failure to follow them
could damage the product or cause a hazardous
condition.
