quality thermostat

Comments about Programmable Thermostat (510 + 079):

This thermostat is programmable and will probably suit any scenario. You may need to have a 14 year old standing by to help program it. We bought 2 and are using them for our radiant floor system so it senses the air and floor temperature. We also connected an extra sensor to it to check the outside temperature.

Tom, in customer service was very helpful in determining that this was the thermostat that would suit our needs.

Finally our cat loves the packing paper. We fluff it up on the floor and it is like she is hunting on the Serengeti. She would give the packing 5 stars.

Comments about Programmable Thermostat (510 + 079):

I use one (1) of these to control all the hydronic floor heat in my 1900 square ft home.

Wiring it is easy. (you need 4 wire and a power source(transformer))

Early start up function.
And it keeps track of trends in calls for heat to help with short cycling.

It keeps my right at the set point. Anticipates temperature changes etc. Awesome
Plus looks good


Great product [...]

    How is the slab sensor usually installed? Does that have to be 'drilled' into the concrete slab or is it a different installation altogether?

    Also, I am currently using a Honeywell rth6300b1005 thermostat. Will this unit work well as a replacement?
