Thermostats have my head spinning...

[tttaylorrr]

What’s the main difference between the ez and then the digital. Is it just a nicer display ?

Havent looked myself but i am going to guess the passive safeties and mechanical relay to shut off power in case of a channel or unit failure. I know anything under the Herpstat 1 does NOT have the mechanical relay.

And the main reason to buy a t-stat is for the safeties and to have it shut down in the off position on failure and not run wide open lol.

the EZ has the main safety relay that shuts the system off if it fails internally. it just doesn't have the internal memory if it turns off or power outage detection. or the backlit LCD screen and the ability to manually input an exact temp.

EDIT: the Intro+ (which is "under" the Herpstat 1) also has the internal safety relay.

EDIT 2: here is the main difference between the EZ and the Intro+; this is what the Intro+ has

Built in Safety Relay on Herpstat Intro+ models to help protect against solid state failures causing "run away" heating.
