          Q:Does anyone know if I can use this to replace an Aube TH115, currently controlling wall-mounted heaters. The manual has (120S/240S/240D) on the cover. The manual mentions 15 Amp, 3,600-Watt maximum load / Double-pole (4 wires) with positive off position.

          Answer This Question

          A:  Aube TH115 is for electrical heating. Honeywell WiFi is for 24 VAC control of furnaces, boilers, and/or air conditioners. So my answer is NO.

          by|May 5, 2023

            A:  Hey Paul! The RTH6580WF is a low voltage thermostat (24VAC). If your TH115 is 120/240 it would not be compatible. If you have further questions about a compatible thermostat, please call us at 1-800-468-1502 so we can learn more about your system. Thank you!

            by|May 5, 2023

              A:  No. This thermostat controls a 24 volt relay system. If you want to control wall-mounted, 220 volt heaters, then this WiFi stat would have to control an intermediate 24 volt double pole relay with 15 amp or greater contacts.

              by|May 5, 2023

                A:  Make sure your furnace has a "C" wire This is needed for wi-fi hookup. Can't tell you about your Aube TH115

                by|May 5, 2023

                  A:  Yes, I installed one of these several years ago. It is good for both heat and air if your system is wired for that. Just follow ALL of the instructions to the letter. Replace the battery every year. Its easy.

                    Q:Can I set it to run for very short periods of time? I don't really want a temperature regulating thermostat - I want to be able to program it to run the AC for 5 minutes and then turn off. The Nest and Ecobee wouldn't do that.

                    Answer This Question

                    A:  A schedule can be set for as short as 15 mins. However, keep in mind these are "Smart Response Technology" thermostats that will continually learn when to pre-heat/cool your home so you are comfortable at your programmed times. So for example, if the room has dropped to 65F degrees and you have a set point of 75F at 7 AM for only 15 mins, the system will start well before 7 AM to warm the room to achieve 75F by 7 AM. Having a set point 15 mins later of effectively "off" (there is no off setting but a high/low set point will do the same) will cause the system to begin adjusting immediately to that next targeted set point. Despite the 15 min setting, I think the duration of heat/cool for you will be unpredictable using a "Smart Response Technology" device.

                    by|May 5, 2023

                      A:  I believe the minimum time interval is 15 min. You could set a very high temp so that the AC does not come on, then have a time when it's on, but not less than 15 minutes.

                      by|May 5, 2023

                        A:  No, this thermostat does not have that function.

                        by|May 5, 2023

                          A:  Hey Bruce! That is a great question! You are not able to program the system to run for a period of time and turn off. Our thermostats are designed to run based on temperature. Thank you!

                          by|May 5, 2023

                            A:  You can do this by tricking the period and schedule system. Set the normal temperature on the schedule to a temperature at which the thermostat will not turn on and then set a temporary temperature at which it will turn on. When the temporary hold expires it will return to the schedule temperature. This will be awkward at best. It sounds like you need a timer switch and not a scheduling thermostat. By the way, cycling your compressor in such short intervals is hard on it. It will not last long.

                            by|May 5, 2023

                              A:  Brief follow-up to my answer below... you can disable the Smart Response Technology option using the system setup options. Setting Function 0530 to "0" will turn SRT off.

                                A:  I don't have this particular Honeywell wi-fi thermostat, so I can't be absolutely sure on this, but I don't believe any of Honeywell's have remote sensors. I love mine, which I mounted close enough to my router so I get multiple bars on the Honeywell.

                                by|May 5, 2023

                                  A:  Not that I know of.

                                  by|May 5, 2023

                                    A:  I do not think you can connect a remote sensor, but you need to ask Honeywell. The wi fi control of this thermostat is excellent, and we have actually moved it to a different location, but the setup and control functions operate thru Honeywell's app and website.

                                    by|May 5, 2023

                                      A:  I don’t think so.

                                      by|May 5, 2023

                                        A:  Hey Ace! We do not have a WiFi thermostat available through retail stores that is compatible with a sensor. We recommend working with your local contractor to find a proper thermostat for your application. Thank you!

                                          A:  When using the hold feature it will only do what you tell it to hold. Using the programmed times/temps it learns how long it takes to get to a programmed temp and will come on early to get there on time

                                          by|May 5, 2023

                                            A:  This thermostat is easily manually programmed by you; not a learning device. I've had this model for a couple of years and it is easy to program and use. You select the on/off periods for each day or the entire week.

                                            by|May 5, 2023

                                            A:  This thermostat does not learn...it only works as you program it or if you specifically change a setting. It is an excellent wifi thermostat.

                                            by|May 5, 2023

                                              A:  It only does what you tell it—or program it—to do. It does no learning, second guessing, etc. I have five of them. Simple to program remotely, or do permanent hold of a temp if you don't want it programmed. Very nice to come home to a warm (or cool) house without having to pay for it to stay that way while we're away.

                                                A:  I have mine on a schedule which I can control via my smart phone. I don't know anything about a learning mode with this thermostat.

                                                  A:  No. After setup, communication to/from the thermostat is by Wi-Fi. So Wi-Fi is a must.

                                                    A:  Yes, as long as you have data plan with your phone and your thermostat is connected to internet. There is an app for that on play store.

                                                        A:  WIFI is required at the location of the thermostat. WiFi or 3G is required to communicate with the thermostat from a remote location. I hope this answers your question

                                                          A:  No. You must have wi-fi to monitor the home temp.

                                                          by|May 5, 2023

                                                          A:  The thermostat is linked to your home router via WiFi and the app is accessed over the internet. You would have to have internet access on your phone to use the app to monitor and change the thermostat settings. If your phone service also offers internet access than you don’t necessarily need WiFi access. I tested this on my iPhone by disabling WiFi and I was still able to access the thermostat through my Sprint service. I love this thermostat since I can change the settings without leaving my bed if it happens to be colder or warner than expected.Hope this helps answer your question. Note: You do need WiFi between the thermostat and your home router and the router needs to have access to the internet.

                                                            A:  The time of day can be adjusted on the main screen For other settings, push the system key. A row of blank boxes will appear at the bottom of the screen. .press and hold the key to the left and the key to the right of the center key for 5 seconds or until the screen changes. When the screen changes release keys. You should see the number 0120 on the left with the number 20 on the right. If it does not say 20, press the up/down arrow on the right until it reads 20 (the first two numbers in the current year). Then on the up/down arrow on the left by the number 0120 press the up arrow until it reads 0130 ( one key push up). If you go too far just use the down arrow to get back to 0130. Now the number on the right represents the last two digits in the current year. If it does not match the current year use the up/down arrow on the right to adjust to current year (at the time of this answer that would be 18) . Then push the up arrow on the left by the number 0130 until it reads 0140 ( one key push up) The number on the right now represents the month of the year. Press the up/down arrow on the right until it is correct ( May would be 5 for example). Then push the up arrow on the left by number 0140 until it reads 0150 (one key push up) The number on the right now represents the day of the month (1-31) adjust until the current day is shown. Then push the key on the left up arrow until it reads 0330. This is for daylight savings time. If you live in an area that uses daylight savings time use the right arrow to set it to #2 (enable DST) If your area does not use DST change the number to 0 (disable daylight savings time). Push the done key when finished. The thermostat will keep the proper date and calendar year from then on even if there is a loss of power due to a small button battery in the thermostat.

                                                                      A:  It may. The three requirements are that your system deliver 24VAC to the thermostat (or you provide it independently), that you have wireless in your RV, and that your gas heater have standard low voltage, low amperage control.

                                                                      by|May 5, 2023

                                                                        A:  No. An internet connection is required for the Thermostat to connect with the Honeywell servers. You control the Thermostat remotely via those servers.

                                                                        by|May 5, 2023

                                                                          by|May 5, 2023
