Default How to adjust honeywell round thermostat (mercury switch) to the right temperature

First, make sure the thermostat is level. If it's
tilted, it won't work right.

How do I adjust a thermostat so that the heat
reaches the set temperature?

My Honeywell round thermostat has a bulb with
mercury in it and a coil of
metal that seems to control when it makes
electrical contact.

When I set the Honeywell bulb thermostat to 68°F,
the heat only gets to
about 58°F. Likewise, when I set the thermostat to
85°F, the heat shuts off
when it reaches about 75°F.

This works fine except my husband keeps yelling at
me for setting the
thermostat to 85°.

I know the simple answer is to change him but why
do thermostats have
numbers on them if they're not even close to those
numbers?

Is there a way to adjust the temperature? When I
pull the round cover off,
I see a copper pointer on the bottom with etch
marks on the plate below but
that pointer is already all the way to the left
and moving it to the right
just seems to make the offset error worse.

What's the procedure to adjust a Honewell round
thermostat to reach the set
point before turning off?
