I set the timings for On/Off ranges twice daily, temperature and Auto on my Fire Genie Remote. Temp set at 17C/62F. Remote occasionally comes on when it is set to be off. Once temp got up to 33C/91.4F in the middle of the night during an Off period and had to be manually shut off. Any ideas why the remote will not remain off as set, or why the temp when set at 17C/62F does not go off until about 25C/77F?
