NOTE: In the event of voltage transients or other EMC interference on the mains
supply the fan may go into boost for 3 seconds or possibly for the run on time period.
Operation will be restored to normal after the interference stops.
If severe EMC interference causes the fan to go into permanent boost the mains
power should be reset to restore functionality.
If high levels of RF interference causes the fan to go into boost during the period of RF
interference EMC mitigation procedures may be required. Contact Nuaire service dept
for further support.
