My friend has a newly installed Venstar T5800 on her vacation home. She monitors the heat remotely during the winter months. She recently noticed that the system status was 'inactive' (or something of that nature). Concerned that her furnace was not running she made a special trip to see the condition. She found that there had been a 'momentary' power outage. She ended up having to reset/restart the Venstar thermostat so as to restart the furnace. Is this what you have to do when you lose power? Even a momentary? We don't see any reference to a battery backup. Is the thermostat supposed to auto reset/restart by itself when this condition occurs? Are there any remote alerts available to assist with low temps, etc? We're hoping that the homeowner doesn't have to recognize a power outage condition and then have to reset the thermostat manually.

I'm not sure, So, I suggest you contact Venstar tech support. They are very responsive. thermostatsupport@venstar.comGood luck

We need to, about 25% of the time, when power is disrupted. Most of the time, it resets without any troubles.

Eric:Like you, I was unable to get a direct read from either of my 2 remote sensors. It, supposedly, will use the readings to "average" the temps, but like you, I would love to see a direct read-out on the face of the stat!Sorry I couldn't help you . . .Mike

I am no expert but it sounds like you have a defective TH 106. The on/off feature on these thermostats is triggered by the temperature at the TH 106. I would return it for replacement. Ted

cycling is not on and off on and off constantly . There is a window of temp change that must occur before the thermostat changes to a higher temp or for the thermostat to react ( go 'on' )due to a tem drop. Ihave not heard this action you speak of nor heard any audible humm. It works not unlike the termostat on your home air conditioner. A very slight temp change is NOT going to make the comprerssor go on - or off. Otherwise -every couple of miutes it would go on or off constantly.

Not sure. I haven't used that feature. But I'm guessing it is used to set when the heater need to turn off not on. I'll let you know on my next post

No, it doesn't. It resets if you unplug it. Regardless of whether it stays plugged in or not, every time you turn it back on you have to manually set the "thermostat" function and temperature, although if it hasn't been unplugged it will default to the last temperature you set it on. There is a light on the front panel so that you know whether it's on automatic/thermostat or just "on".

The unit CANNOT be operated during a power outage..it has an electronic ignation which needs the power to function. As for having to manually reset the unit after an outage, we have never had to do any reset on the already input settings dispite many outages due to heavy snow... Hope this helps...we have two (2) units and love them.....

Directly, no; indirectly yes. You'll need to contact the mfg tech support. They mentioned something about an alert service for a fee. The RadStat app allows control such as off/on, temp setting, home/away--normal thermostat actions. I think for the alarm (such as to note whether your heat has failed in the winter) you need to have the stat monitored, and I think some alarm companies do that too. There is chatter on their website forums about alarm.com.

Yep, I've had mine running all winter long. The unit itself doesn't get hot and once the room reaches the desired temp (set by you) it goes into power save mode.

My thermostat touch screen also failed. I replaced the wall maounted unit (not the controller mounted at the furnace) and it now works fine. If you have a high efficiency system with multiple heating/cooling settings, you will need to program the thermostat. I didn't learn this until a later furnace tune up when I was told the system was using only the low load setting. The technician programed the thermostat.

No battery backup in mine. However if the power goes out, your furnace won't run it's fan anyway. When the power comes back on, the thermostat will resume as left off. We have ours in a vacation home and the power goes off intermittently throughout the winter. The thermostat is always reset and functioning when I check back in. I really enjoy this thermostat for checking in on the house and the external temperatures remotely, and for turning on the heat before we arrive in the winter.

I believe if the batteries are dead or missing, the thermostat won't work and the heater will not come on. It makes sense but I never tested it.

I would recommend checking the amp draw of the elements, when the thermostats or NOT CALLING (on). If there is any draw at this time, then the element needs to be replaced.

I didn't have a C wire when I installed my thermostat. From what I can figure, the C wire is used for power, and the batteries will kick in when the power goes out. My previous thermostat was programmable with batteries. The batteries lasted a long time in that thermostat.You can set the temperature range where you want and leave it. For some reason, my Vera 3 set up 3 thermostats. 2 are like ghost thermostats, and 1 is the real one. But, I can access and control that thermostat from anywhere. I also set the poling time lower so that it checks the temperature on the thermostat more often. I think I set it at 1/2 hour. I didn't have a C wire when I installed my thermostat.

Great question. I just went in and interuppted the power by tripping the breaker. After 3 minutes I restored the power and the Air conditioner started right back up with no input from me at the correct temp!

I have a couple of questions. First - have you talked with your electrician about this? Next, I don't understand your description of the problem. If the breaker trips when the thermostat kicks on, how does it get power to go up to 76? One issue with these thermostats is that they are designed to work on electric baseboard heat (resistive load). If the load is inductive (say a heater with a blower motor) they don't work. Finally, you may simply have a defective unit. Do the other 4 work properly?

I think it doesn't have to be reset. But overall this heater never worked for me to maintain the temp. May be mine was defective.
