Type: User manual

Daikin IM 1314 is a high duct pressure limit switch designed to protect your HVAC system from excessive duct pressure. It features automatic enablement and factory programming for a normally open configuration. The unit can be reconfigured for a normally closed state through the local user interface or ServiceTools software. Additionally, the device can be used with a field-provided duct pressure tap to monitor downstream static pressure and initiate an immediate shutdown if the connected switch closes, indicating a high duct pressure fault.
