Heater? or Heather(s)

[Metrontech]

Problem is I can't get 3 of them to even stop turning on

No matter what temperature I set them to

Even the absolute lowest temp and it still stays on

So frustrating, and it seems like my new 4 bulb t5 lights are causing it to stay at 79.5 and then at night of course if gets really cold

Argh

How old are your heaters?
