What you describe is not the heat anticipator. The heat anticipator shuts
the heater off a little before the thermostat reaches the set temperature.
This happens every time the thermostat is calling for heat.

I told him this was ridiculous. The thermostat should show the correct
temp and it should not take 3 hours to bring my heat from 65 to 74. He
said that Honeywell digital t-stats do not have a heat anticipator.

Some of their programmable t-stats sure do have an anticipator circiut in
them. Mine does, a CT3500. The morning "wake" program isn't scheduled to
start until 7am, but the thing starts heating the house at about 5am (I'm
guessing) to get from the "sleep" temp of 60 to the "wake" temp of 70 by
the
start of the wake program time. This feature can be turned off too.

I have a hot water heat system, FWIW.
