Hello growers, iv searched the net for answers but found nothing. I bought an SMSCOM fan controller with thermostat 2 days ago to control my RVK100 extractor fan. Iv had it all rigged up working fine, when the temp got high the extractor fan kicked in, when it got to the desired temp it went back to the idle speed i'd set. Today it seems that the idle speed has stopped working. When i turn the fan idle controller up to max the extractor kicks in full speed, when i turn it down, even slightly, the fan stops turning and hums loudly. The fan works as normal when not connected to the controller. My question is, has the controller developed a fault or have i damaged my extractor fan by running it at a low idle speed.
