I have the new WiFi Apex. I have my heater set to turn on at 79 and off at 80. In the last few weeks the temp has dropped down to as low as 77 before the heater come on. I have a RedSea XL525 with a 300 watt heater in the sump. The off temp works OK. Is it possible that the last firmware update might have screwed things up? I checked with tech support, they logged int my fusion account, and seemed to thing the system was working properly. Any ideas?
Regards,
Jon Blake
