The control enclosure may be constructed of stainless steel <br />or painted steel. <br />Temperature probe(s) located in the exhaust duct riser(s) shall be constructed of <br />stainless steel. <br />A digital controller shall be provided to activate the hood exhaust fans dynamically based <br />on a fixed differential between the ambient and duct temperatures sensors. This function <br />shall meet the requirements of IMC 5.7.1.1. <br />A digital controller shall provide adjustable hysteresis settings to prevent cycling of the <br />fans after the cooking appliances have been turned off and/or the heat in the exhaust <br />system is reduced. <br />A digital controller shall provide an adjustable minimum fan run-time setting to prevent fan <br />cycling. <br />Variable Frequency Drives (VFDs) shall be provided for fans as required, The digital <br />controller shall modulate the VFDs between a minimum setpoint and a maximum setpoint on <br />demand. The duct temperature sensor input(s) to the digital controller shall be used to <br />calculate the speed reference signal. <br />The VFD speed range of operation shall be from 0% to 100% for the system, with the actual <br />minimum speed set as required to meet minimum ventilation requirements. <br />e system Mail operate 7. E auring ng oa oFr-G=#7*TTM"FE`w=er <br />sufficient heat remains underneath the hood system after cooking operations have <br />completed. Operation during either of these periods will disable the supply fans and provide <br />an exhaust fan speed that is equal to the minimurn ventilation requirement. <br />A digital controller shall disable the supply fan(s), activate the exhaust fan(s), activate <br />the appliance shunt trip, and disable an electric gas valve automatically when fire condition <br />is detecte <br />A digital controller shall allow for external BMS fan control via Dry Contact (external <br />control shall not override fan operation logic as required by code). <br />- An LCD interface shall be provided with the following features: <br />a. On/Off push button fan & light -switch activation <br />b. Integrated gas valve reset for electronic gas valves (no reset relay required) <br />c. VFD Fault display with audible & visual alarm notification <br />d. Duct temperature sensor failure detection with audible & visual alarm notification <br />e. Mis-wired duct temperature sensor detection with audible & visual alarm notification <br />f. A single low voltage Cat-5 RJ45 wiring connection <br />g. An energy savings indicator that utilizes measured kWh from the VFDs <br />Sequqncq���� <br />The hood control panel is capable of operating in one or more of the following States at any <br />given time: <br />- Automatic: The system operates based on the differential between room temperature and <br />the temperature at the hood cavity or exhaust duct collar. Fans activate at a <br />configurable temperature differential threshold. Depending on the job configuration each fan <br />zone can be configured as static or dynamic. These terms refer to whether a variable <br />motor (such as EC Motors or VFD driven motors) modulate with temperature. If the panel is <br />equipped with variable speed fans and the zone is defined as "dynamic", these will modulate <br />within a user -defined range based on the temperature differential. Panels equipped with <br />variable speed fans and a fan zone defined as "static", fans will run at a set speed <br />calculated for the drive. Demand control ventilation systems are capable of modulating <br />exhaust and make up air fan speeds per the requirements outlined in IECC 403.2.8. <br />- Manual: The system operates based on human input from an HMI. <br />- Schedule: A weekly schedule can be set to run fans for a specified period throughout the <br />day. There are three occupied times per day to allow for the user to set up a time that is <br />suitable to their needs. Any time that is within the de ined occupied time, the system will run <br />at modulation mode and follow the fan procedure algorithm based on temperature during this <br />time. During unoccupied time, the system will have an extra offset to prevent unintended <br />activation of the system during a time where the system is not being occupied. <br />- Other: The system operates based on the input from an external source (DDC, BMS or <br />hard -wired interlock) <br />La <br />• <br />FTmEI_RES; _2/18/20 1 <br />@2018 1 ALL RIGHTS RESERVED <br />DRAWN BY I SCHRIVER <br />CHECKED BY I NITSCHKE <br />REVISIONS <br />An 05/29/2019 New Opt 3 Plan <br />06.29.1711:08PM I BCOSTC0\0114 Everett, 1NA\BIMCADN1Mech\M104.dwg <br />Is- wi, <br />6191MUMP1161A MY <br />
