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.
