## Description

Honeywell,TH115-AF-GA ,120/240v 7Day DPST ElecHtStat. 7-day programmable line volt thermostat for elect.

Review: Did the job perfectly - Thermostat was a perfect replacement for my the one in my heated bathroom floor...easy to install and to program, what more could I want?
Review: Works as it should. - If you are reading this, you should be pretty familiar with your options. This unit allows for floor sensing and the modes allow you to heat to a targeted floor temperature, targeted air temperature, or a targeted air temperature while controlling the min and max floor temps. It also allows separate schedules each day with 4 settings per day. Things to know about this (if they matter to you): * You can use either 120 or 240v, depending on how you wire it. * The included instructions do NOT agree with the markings on the unit itself. Input/Output are different in the instructions versus the unit itself. I don't know if this is a typo or a translation problem. (I followed the unit markings and it seems to be working well.) * If you opt for a 24-hr (military/European style clock, you can only have CELSIUS temperatures. Otherwise you only get a 12-hr (AM/PM)/Fahrenheit display. * It does have a heat anticipator option if you want it either click on or off at a certain time or if you want it to decide when to turn on and off to reach the target temperature by a certain time. I like it and recommend it.

## Questions & Answers

**Q: Can you connect 2 circuits to this thermostat?  For example, run 2 heated floor mats simultaneously on this thermostat....**
A: The thermostat will allow you to control a resistive load of UP TO 15 amps. If the total ampacity of 2 heated floor mats is 15 or less, then yes, you can.

**Q: Will this work with Viega radiant system?**
A: This thermostat is a 120 volt Line Voltage thermostat designed to be used with electric heating systems.  It appears that the Viega system is a hydronic heating system that uses hot water.

**Q: I have an older warmup pb112b programmable thermostat.  will this unit replace my old one?**
A: It is a generic thermostat so it should replace pretty much anyones

**Q: Can i use this unit to replace a nuheat solo thermostat?**
A: I dont see why now, they are all basically the same, just different options.  The heating pads are all 2 wire simple connection.  Only issue may be the thermostat connection?

### ⭐⭐⭐⭐⭐ Using it for under floor heating in bathroom.
*by B***Y on December 1, 2023*

Easy to set up and get running right out of the box. Bright easy to read display. If you are replacing an older model thermostat, check the sensor loop resistnce of your sensor wire with an ohm meter. Mine read 17 ohms. This new model comes with a sensor wire that measures 12 ohms. If that's your case, and you decide to keep using your old sensor wire, you may need to up the temperature setting on this thermosat by a few degrees in order to compensate for the higher risistance in the sensor wire. I did that and it works fine.
