interfaced to these Hood System, the sequence of operation will vary. Sometimes the Intelli‐Hood will
trigger the Hood Panel while in other installations, the Hood Panel will give a start signal to Intelli‐Hood.
Refer to project‐specific documentation for more information.
Remote Input by Building Automation System
The Intelli‐Hood System supports BACnet protocol. Through BACnet communication, a Building
Automation Network may command Intelli‐Hood system to turn fans on/off at specific times.
High Temperature Alarm Mode
High Temperature Alarm Mode is similar to Auto On Function. When the temperature of a hood
reaches a setpoint (default setting is 200F), the exhaust fan will turn on full speed and run for a
minimum time of 5 minutes. After the 5 minute time period, the Intelli‐Hood system will operate in
normal Energy Saving Mode. High Temperature Alarm mode is a default feature of Intelli‐Hood.
Internal Clock Schedule
Intelli‐Hood can be programmed to turn on and off at specific times of the day based on the real
time clock of the Intelli‐Hood Controller.
Multiple Modes
Intelli‐Hood can be programmed such that several of the above methods can turn on a system.
For example, Intelli‐Hood can be programmed to turn on at a specific time of day every day, but if a
kitchen staff person wanted to start or stop the fans with the Touchpad or Aux Touchpad, then he/she
would be able to do so.
