Wirsbo radiant parasitic thermostat problem

diklang

My 20 year old Wirsbo thermostat now shows ALL icons and symbols all the time and I have no Idea what it is up to! I would be fine trying to figure out how to repair it but how? Or is there a replacement that doesn't cost a hundred bucks?

It's fried. What is it switching? There are less expensive thermostats (there are cheaper ones, too — not the same thing) but without knowing what it's supposed to be switching and how much fancy control you want…

It just controls the hydronic under floor heat in the bathroom. Nothing fancy, pretty much remains un changed all year! sixty eight degrees. The current thermostat has only two wires and no batteries.

The I'd go to the Big Box or Amazon and get a Honeywell/Resideo T87 — this one:

Amazon.com: Honeywell Home CT87K1004 The Round Heat Only Manual Thermostat : Honeywell

They work just fine for what you want.
