Choosing a Physical Location

You can install the controller almost anywhere, but it is more secure and reliable if you install it in a
secure equipment room or wiring closet. For maximum reliability, mount the controller using the
following guidelines:
Warning To prevent the system from overheating, do not operate it in an area that exceeds the
maximum recommended ambient temperature of:
104° F (40° C) Statement 1047
Warning To prevent airflow restriction, allow clearance around the ventilation openings to be at
least:
4-in (10.16 cm) Statement 1076
Warning Take care when connecting units to the supply circuit so that wiring is not overloaded.
Statement 1018
• Make sure you can reach the controller and all cables attached to it.
• Make sure that water or excessive moisture cannot get into the controller.
