my hubby just told me our heat does not come in the night unless it get's below 64 in the house. But he has it set to go off in the morning around 5:30 am to 70 so it is not freezing when we get up and then it is set to go off after 4:30 during the day if it get's below 68. but turns off at around 9 pm. We also have lot's of throw blankets we get under during the winter. Including 3 cats!
