Just installed tile flooring with thermosoft heat mat under it
this is the mat [url=http://www.thermosoft.com/radiant-floor-heating-products/shop/thermotile-240v/]http://www.thermosoft.com/radiant-floor-heating-products/shop/thermotile-240v/[/url]
this is the current thermostat [url=http://www.thermosoft.com/floor-heating-thermostats/aube/]http://www.thermosoft.com/floor-heating-thermostats/aube/[/url]

Does anyone know of a way to integrate this with z-wave (veralite)
thanks

I don’t see any mention in the documentation that the thermostats have Z-Wave capability. If you want to control the setpoint with Vera, you would need to replace the thermostat with one that has Z-Wave or IP connectivity.

exactly what I am looking for. You are correct, the termostat that comes with the system has no connectivity. Wanted to find one that would function with vera and control the heat pad.

I’m also looking for this type of thermostat. Any luck out there?

5

has anyone figured this out? I was just about to buy the exact heated floor tiles.

If the room already has Z-Wave HVAC Thermostat for that area … I would control with a Z-Wave Relay.

I would use a PLEG routine to turn on the Z-Wave Relay (for the floor heat) when the Room Temp (As reported by the thermostat) is less than the Heat Setpoint (As set on the thermostat).

If there is no HVAC for that room, Add a Z-Wave thermostat and use the thermostat to engage a NON Z-Wave relay directly to control the floor heat. The Trane thermostat would work fine for this … it will have features you do not need …

could you go into more detail, I have a radiant heat mat under tile, 240v. Could you give a setup for dummies explanation
thanks

Which scenario ? Do you have other HVAC and thermostat for the same area ?

Yes, forced air heat/ac for living area. Tile floor radiant heat is in a 20 x 12 ft living room. Thermostat is in kitchen, about 15 ft away. Radiant heat is on a separate
thermostat in living room with sensor in the floor.

house thermostat is 2 gig ct100 z-wave
thanks

You can eliminate that floor thermostat … It acts as a POWER relay … 220V up to 15Amps.

Replace with a relay/contactor 120V coil … DPST relay rated at 15Amps resistive.
Drive the relay from a LFM-20-Z-Wave-Relay. Although this could probably drive the load, It is only a SPST relay … I prefer DPST for 220V. I assume you have a GFCI at the fuse box.

If you do not follow the above … you really need to talk to an electrical contractor.

Then you can use a PLEG plugin to control the Z-Wave relay based on the difference between the air temperature and the heat setpoint on your CT100.
You can get fancy and use a different delta based on outside temp using the Google Plugin.
