Functionality
Fan Control
The control panel controls fans through starters. Each ECPM03 board can control 1 or 2 Fan zones. A fan
zone includes all exhaust fans and supply fans that will come ON and OFF simultaneously. Fan zones
are typically independent from each other, except in certain conditions like fire.
Hood Lights
1. A control panel can have 1 or 2 HMI light switches. Typically each light switch controls one light
circuit with a maximum of 1400W per circuit. If more than 2800 watts of lights are needed,
additional 15 amp circuits can be brought to the panel and be run through a lighting contactor.
Panel specific lighting limitations are indicated on the installation schematic.
2. Hood lights can be controlled manually through the Light button on the HMI screen. They will also
be automatically turned ON or OFF when the fans assigned to that same fan zone turn ON or
OFF. Manual light switch command on the HMI screen always takes priority.
Electric Gas Valve Reset
If the Gas Valve option is turned ON, an additional button is displayed on the HMI screen to allow the
user to reset or re-energize an electric gas valve connected to the panel. The gas valve is de-energized
at initial startup, when the Fire System is triggered or in other conditions as well.
Refer to paragraph (h) under Configuration section to turn this option ON or OFF.
High Temperature Automatic Appliance Shutdown
When any of the duct temperature sensors reads a temperature above the Appliance Shutdown
Temperature threshold settings (Factory Default: 250 Deg °F), any electric gas valve wired to the panel
will shut down and the shunt trip output of the panel will activate. This is intended to prevent potential
fires. The activation threshold set point can be adjusted under Configuration/Fire Options.
Appliances Pilot Check Warning:
Every time an electric gas valve is reset, a warning message will be displayed on the HMI for 1 minute. A
CLEAR button will be displayed on the HMI to clear the warning message and stop the beeps. If after 1
minute, the clear button is not pressed, the message disappears. This message is normal and provided
as a reminder only. There is no need to take any action.
Building Management System (Dry Contact)
1. All controls are equipped with the ability to control the fans via a dry contact BMS interlock.
Terminal IO1 should be energized by closing a dry contact placed between terminals H1 and IO1.
NOTE: the CO Censor option must be disabled for BMS dry contact functionality. If two HMI are
present (two fan groups), terminal IO1 will control the first group, and terminal IO2 will control the
second group.
2. Removing the signal from IO1 will typically cause the fans to turn off. However if the duct
thermostat sensors are hot or if the fans are energized through the fan button on the HMI, then
the fans will continue to run.
NOTE: If the panel is ordered with a digital building management option, such as CASlink, BACnet, or
Lonworks, please refer to the Building Mana
gement Owner’s Manual for alternative fan interlock
scheduling.
