Installation
Pre-installation Information
If the controller has not been removed from its shipping carton, inspect the carton for
damage then remove the controller.
• Inspect the unit for any obvious shipping damage and report any damage due to
transit to the carrier.
• Make sure a bag containing mounting hardware is included in the carton with the
controller.
• Check that the model number shown on the inside of the case agrees with what you
have ordered.

2.2 Condensed Specifications

Honeywell recommends that you review and adhere to the operating limits listed in Table
2-1 when you install your controller.
