The contractor installed a wall-mounted thermostat (with TINY grey display!!!) that measured air temperature.

The house was either too hot or too cold. Up & down, up & down adjustments while peering at the pathetic display.

By using an infrared scanner, I found a neutral spot in the concrete floor when the temperature reflected the average concrete temp.

So, I ripped out the wiring, threw away the "popular" thermostat & bought this one.

I chiseled out a 1.5" grout line & cemented the floor sensor in place.

With the floor temp on 75, the water temp on 120 degrees, the house is cozy in the low 70's - almost too hot, so I'm still tweaking.

With the air thermostat, the boiler would run for hours till it got to temp, now it runs 10-15 minutes & shuts off. I cant wait to see my fuel bill next month.

This unit is incredibly easy to adjust, the install took one call the mfgr tech support to verify the correct wiring.

Well worth the price - a great value for the price.

I used this to replace a flooer thermostat no longer available from Watts Radiant.

The 519 was easy to install and set up, and has been trouble free so far. The instruction manual is clear and well written.

Easy to set up

By Geo Jeff

from OH

Verified Buyer

Plan the installation with a tube inserted into the floor slab if using the remote sensor. This control will allow for operation via air sensor in the stat or with the floor sensor. Control will interface with most any radiant heat control panel for pumps or zone valves.

Perfect for what I needed

By Bladeguy

from Wisconsin

Verified Buyer

Use this for my basement. Right now I'm using it to control the slab only, and it works better than I could have imagined. I recorded the thermostat for 6 hours, and I found it actually kicked on before it dropped below 72 where it was set. It did overshoot to 73 on occasion, but that is due to all of the hot water sitting in the floor, nothing the thermostat can do about that. Keeps my basement at 68-69 degrees, which is great for that new theatre room! Only gave it 4 because the instructions didn't work with my relay, so I had to figure it out myself. Not a big deal, but I was a little surprised by that.

  • Q:

    I have a radiant heat slab with peerless boiler, Beckett burner. The boiler has Honeywell L7224U1002 Aquastat and TACO SR 502 relay for heat zones. Will I need 4 conductors to hook up this thermostat? 24v & TT.

    Can the slab sensor be laid on top of the concrete directly under click laminate flooring?

    I have an eight zone system using Tekmar thermostats. Are there any wifi thermostat systems so I can change settings while away from the building?

    • CUSTOMER CARE

      A:

      There is the TekmarNet Internet Gateway, sku 485 that would enable TekmarNet thermostats to be accessed remotely. Only that product line of thermostats would be compatible with this Internet Gateway.

    I have radiant floor heat and the thermostats are 2 wire low voltage. What product do I need to put a floor sensor thermostat in? I can't find a 2 wire thermostat.

  • Q:

    I have an 8 zone radiant floor system that currently uses regular old thermostats meant for forced air. I am seeing that these style thermostats such as Tekmar Radiant Floor Thermostats would work better.

    To replace my previous thermos, without using the floor sensors, do I need to do anything special or will the wiring that is currently provided in the wall work?

    Thanks
    Asked on 5/24/2015 by Mtn Man from Colordao

    1 answer

    • CUSTOMER CARE

      A:

      With out knowing the thermostats you are replacing I can;t say whether or not they will be a direct replacement, if you are not using the floor sensor it will work no differently than a typical wall thermostat.
