I have a customer that wants to lockout the program, leaving occupants with only the ability to temporarily change the setting - a fairly common request I think.
I liked the Totaline thermostats that had the keyed plastic cover accessory. That gave them a physical lockout. It seems those stats are no more.
Honeywell's Ultrastat requires that you dive into the configuration menu to activate and deactivate the lockout. I don't much care for it.
Any other good options?
