How many mats can I connect to this thermostat?

The Honeywell thermostat will handle up to 15 amp load either 120 volts or 240 volts the way you cross the volts to amps is 1800 watts will equal 15 amps for 120 volts if the mat is rated for 240 volts would be 3600 watts know the rating of the floor heat mat if not know call the manufacture of the floor heat mat.

Generally only one, and that one has to be less or equal to the total watts of the mat. There are larger rated units for more watts if needed.

In general you can connect up to 300sqf. As long as it doesn't exceed 15amp in total.

If you have two thermostats you should buy two combo sets. You can set a code to control each thermostat and unit. I have more than one and it works fine.

Sorry - I have not as yet installed the thermostat. Honeywell product support should be able to answer your question.

This Thermostat takes 4 wires. Compare the wiring design of your current thermostat with the Honeywell. I had to run the 4th wire for my system which was the C wire.

If you have enough wire, just connect them in the junction box with the thermostat. You should really just try and find mat that is large enough for the area you need. DO NOT CUT THE WIRES IN THE MAT!

I am going to assume you have a heating and cooling system. That being said, you need to have five wires in your thermostat cable from the furnace unit to the thermostat. Refer to page 46 of the VENSTAR manual - the 5 wire, 1 stage cooling/heating diagram. The color coding is as follows: R(red)=24 volt power; W(white)=heat; Y(yellow)=cooling; G(green) =fan; and blue(for me)=common. This is where the trick is - you must have five wires so that the common can be connected between the furnace and the thermostat. The older systems did not need the "common" because they were not a powered devise. If you don't have five conductors in the thermostat cable then you will need to replace the cable.

Each mat is 15 sq.ft. and uses 3 amps. You would need 6 mats to cover 80 sq.ft. using 80% of the circuit breaker rating you would require a 25 amp breaker. If you can make it work with 75 sq.ft. you would be able to use a common 20 amp breaker.

I don't see how you could. When you add the extension, there is 2 snaps to connect the extension to the main mat. It's my understanding that you would have to buy another main mat to plug in the second extension. Have you checked out all the different sizes? I'm happy with my mats & hope you are too.

Two for heat only; 4 for heat and air-conditioning. How many do you have in your wall?

if you have three heating zones, yes you will need three alarms, if only one thermostat in house then put one alarm on coldest floor

I installed 3 in our vacation home built in 1986 and have a 4th to install next time I am there. It is a 2 wire system and there are only 2 connections on the new thermostat (2 line in and 2 load out) works great.

We had 2 heat mat and had them plugged into a extension cord with a three plug end. we didn't use a thermostat on ours and it kept it plenty warm. we use a light on a timer coming on at 6 and going off at 6. We use light bulbs called daylight in a T8 size . Hope this helps you

No it doesn't. It's only the thermostat. The sensor should come with the radiant mat. You can purchase the sensor separate, I believe.

Not sure whether or not they can. Can you provide more details as to what your trying to accomplish by having 2 thermostats.

If there are 2 leads, it should work. You will need to install a GIF prior to the thermostat.

we have 5 connected with no problems... not sure on manufacturer's numbers...

Yes, you need at least 6, but can add another 2. The instructions explain it.
