Thermostats
There are two
commonly types used:
Digital
Digital
thermostats are more accurate because they use
electronic thermistors to measure the
temperature. They do not need to be level on the
wall to read the correct temperature. Digital
thermostats offer set back of temperatures while
you are gone from your home and allow you to set
them to raise your temperature before you get
back. These are energy saving features.
Mercury
Mercury
thermostats use mercury in a sealed switch to
turn the temperature up or down. Mercury
thermostats must be level on the wall to read
temperature correctly. If it is not level your
room setting will be off. Currently there are
few enhancements to mercury thermostats.
Mercury is being used less because of
environmental concerns.
