Great for radiant floor heat
By Watcher (from Portland, OR) on 12/22/2011
"I was already familiar with these but I needed more than my normal supplier had available. So thank you Pex Universe. The output on these is a simple SPDT dry relay. They are rated for low voltage or line voltage applications as long as the current is within their limits. They are battery powered for the thermostat's operation. Our use of them has the batteries lasting at least a couple of years normal service. We like these for simple radiant floor heat installations. They have a lot of flexibility for heat only applications. They look nice and are easy to install and set up. The best feature is the pump exercise function which helps prevent off-season pump seizing. Most thermostats can't do that and the ones that I know of that can cost more. These won't work for heat/cool applications nor do they allow operating a fan as a seperate function. But within those limitations, these are a great little device. And for a Honeywell, very reasonably priced."

Are these thermostats suitable for a hot water heating/hydronic system? We are considering them to replace the old Honeywell mechanical mercury switched thermostats for each zone.

These are Line Voltage thermostats and are intended mostly for electric baseboard or fan-forced heater applications. Most hot water heating applications utilize conventional 24V thermostats, such as Honeywell's PRO, FocusPRO, VisionPRO or Prestige series.

How to turn it off
Read 1 answer
The unit does not have an On/Off switch. If you do not have an in-line power switch for the thermostat, you can turn off the heat by programming the "Vacation" setting to a lowest desired temperature and use it instead. The details are in the manual.
