By moving... I mean adjusting the room temp in the house. If it is at 65 deg and I slam the lever fast to 85 deg will any harm be done?

Depends. If you have a heat pump and a mechanical thermostat then breakers and fuseholders can trip or be destroyed. With electronic thermostats this usually isn't an issue if the tstat has anti-short cycle protection.

If it's a single stage system then it won't get any hotter any faster. There is a point of diminishing returns using a multistage system, but that point is not usually known. It might be that 4-5 deg above setpoint, the second stage kicks in immediately.

Why would you need to slam the lever fast? Is there a reason, does it work better by doing the slam thing?

It is a Hunter .

OK,, now I understand,I should have known

Sounds like one of those "Comfort Game" models, whereby you try to ring the bell at the top and be rewarded with heat. Not to mention, impress your girlfriend.

When one doesn't like it cold as I had set the temp at 65 deg, my wife slammed it up to 'the end'. Ain't been the first time... sure won't be the last. I just wanted to know if this could damage anything. I didn't know this site was a subsidiary of "Click and Clack!" I enjoyed all the responses none the less

It is never good to give the thermostat a hard ride. Like anything else you can break the plastic levers if you are ruff enough. Put a thermostat guard on the stat and drive her nuts when she can no longer get to it. LOL

Thanks... I will

At my age it would not make a difference. LOL

You could throw your arm out.

One direction and stopping no. But moving a mechanical stat back and forth can blow up a breaker/fuseholder when a compressor doesn't have anti-short cycle protection.

In heating mode, that usually isn't an issue.
