We have a wall-mount Fujitsu Halcyon "Inverter" blower unit in a computer/data room with a 3ish ton condenser in the ceiling above it (between the ceiling tiles and the concrete floor above it). We've been running this configuration for a few years, but recently we installed continuous temperature monitoring for the output of the A/C unit. We noticed it spiking every 12 hours. We observed the behavior in the room first-hand and could actually hear the compressor kicking off and the fan air output reaching room temperature. 3 minutes later, the air started cooling again and back to normal. We've observed the compressor cycling every 12 hours for several days now....no idea how long it's ran this way. It occurs around 1:30 am and 1:30 pm MST within 2 or 3 minutes. If anyone has any experience with such an issue or could provide any insight into what is happening here, it would be appreciated. The fan continues to blow air during the compressor outage, and all timer schedules have been cleared.
