I have a Triton Big Bear air filter on my heating system. I just
installed a new programable thermostat that monitors the number of
hours on the air filter. The most information I can find is to change
the filter at the beginning of each season. My question is. Can anyone
tell me what the recommended change is in hours so that I can make use
of this feature on the Thermostat?

Every three months or 2,160 hours. 24x30x3=2160

That doesn't make any sense. Change it when it is dirty.
