Minimum Room Temperature
This option is designed to prevent unnecessary automatic fan activation due to excessively cold room
temperatures. This value is adjustable between 50 degrees and 85 degrees. As long as the room
temperature reading is above the Min Room Temp set value, the package will use the actual room
temperature sensor reading to calculate the duct thermostat offset. However, if the room temperature
sensor reading is below the Min Room Temp set value, the package will ignore the actual room temp
reading and use the Min Room Temp set value as a reference instead. This prevents a system from
activating the fans unnecessarily, due to a large gap between room temperature and the hood duct
temperature. This option can also help alleviate fan activation troubles with lower temperature
appliances, which are not satisfying the minimum temperature requirements for fan activation.
Self-Cleaning Function (Optional)
1. During the wash cycle, water will be sprayed in the plenum and duct and surfactant will be
injected at a set frequency. The wash cycle will stop when the wash timer expires or when the
Wash button is pressed again.
2. The wash timer is factory set to 3 minutes and is adjustable through the Configuration Menu. The
surfactant is injected for 1 second at the start of each minute of Wash. This setting is not
adjustable. If equipped with CORE Fire Protection, the wash timer is not configurable through the
ECPM03 control board. Refer to the CORE Owner’s Manual for further information.
3. Hood filters MUST remain in place during the wash cycle.
4. The wash cycle can be initiated in several ways:
a. Manually, when the WASH button is pressed on the HMI.
b. Automatically, if the following conditions are met
Fans will need to go out of modulation mode either with the FANS button being
pressed or by the duct temperature cooling down and hysteresis value and timer
are met.
The fans will need to have effectively run cumulatively for a period of time longer
than the “Wash Min Fan Runtime” value configured under “Misc Options”.
Preparation Time mode and Cool Down mode fan time do not count towards
runtime. The runtime is reset to zero when the wash cycle is run.
The amount of time elapsed since the previous wash cycle is greater than the
“Wash Min Interval time” value configured under “Misc Options”. That elapsed
time is reset to zero when the wash cycle is run.
c. If a Building Management System (BMS) is remotely controlling the fans through the
external input terminal IO1, when the Fans are turned ON and then OFF through the IO1
terminal, granted that the fans are not maintained on by the duct temperature sensors or
the fan button.
d. Through a digital Building Management System. Refer to the Building Management
Owner’s Manual for more information.
5. If the surfactant level is too low, an alarm will be triggered on the HMI. If the wash cycle is
initiated while this alarm is active, water will be sprayed but no surfactant will be injected. Refill
Surfactant as soon as possible for best results. (Refer to Self-Cleaning or CORE Manual for
additional information)
