Hello, I have an 8 foot baseboard heater and picked up a Honeywell RLV3100A to replace the ancient knob thermostat that was totally inaccurate and at times caused the heat to never come on, or stay on until the room was burning hot.. Nevertheless it's gone.. It as a 4 wire with ground attachment setup.. The new thermostat is 2 wire. I pushed the ground back into the box since there is no attachment for it on the new plastic unit (the main ground wire going downstairs is still attached to the electrical box itself) and wire nutted the 2 white wires together, and wired the 2 blacks to the thermostat. It has its own beaker so I am able to shut it off safely when off season. I'm assuming it's still safe and breaker protected since the ground is running to the box (but no longer to the thermostat itself since it's plastic I'm assuming?). Anyway that aside it works great but I do have a few questions. Before I ask the questions I'll note that it has icons for flames, from 0 - 5 flames. 5 flames is 100% heating activated, and anything less is partial.. 0 is off. Once it reaches the desired temp, say 70, it usually goes down to 1 flame as it should and holds the temp right there very accurately. My concern is that it sounds like it's cycling on and off every 15 seconds or so to do that. The old unit either had 100% on or 100% off, and you can clearly hear the pinging noises from the metal heating / cooling. With the old unit it only did that once every 15 or 30 mins or so presumably because of the 5 to 10 degree swing range of the old POS thermostat. With the new one, I can hear the sounds it used to make every 15 to 30 mins now every 15 seconds only once it reaches the desired temp and has only 1 or 2 flames on the display. Does it maintain slight heat by on-off? or does it actually send less wattage to the unit? Is the constant cycling safe and normal? Also note that at 5 flames it heats up just like the it used to.. makes the noises until it warms up then stays on until reaching desired temp.. (not every 15 seconds as when it goes down to partial power to maintain) Also note: Someone on Amazon said the cycling is normal and that's how it maintains precise temp control.. Thanks

I've got a 30 year old heat pump that I don't use very much but when I need it, it's fine. It had a York Honeywell FuelSaver that had a rotary dial to set desired temperature that was becoming very inaccurate. This unit did not have a battery. So I replaced it with a Lux TX 1500 which does have a battery. I use the Lux in another part of my house, liked how it worked and had a spare. The Lux TX 1500 isn't very new but thought it would meet my needs. Got it wired in and now nothing works. No heat, cooling or fan on manual. I've attached a photo and wiring diagram of my original thermostat as well as a photo and the suggested wiring diagram of the new thermostat. Couple of things I noticed. Before I took the old thermostat off, I checked the voltage from R - red to X black and got almost 12 volts, thought I should be getting 24 volts. But now that I think of it, I might have had the voltmeter on dc, is transformer ac? Now, with the wires hooked up, I don't appear to have any voltage. I had turned the power off while I was doing the rewiring and yes I turned the power back on. I have jumpered the red to green but the fan did not start. I've seen mentioned the I should have either o or b connected but not both. Looked like my old thermostat had both connected. From reading other posts, I think I need G - fan, R - power, Y - compressor and my manual says this should be jumpered to w, B - chg over. There is also an O shown as alt in my manual. I've taken the wires off the tstat and don't find voltage either dc or ac using the red wire and any of the other wires. So maybe I need to get in the crawl space and check at the transformer. And how do I identify which wire or wires I need to connect for the change over, reversing valve? I've attached photos of the old/new tstat and also wiring diagrams. These were .png files now labeled as .jpg. Not sure if they have been converted or not. woops, not sure what happened with attachments, will repost attachments Thanks[ATTACH]58863[/ATTACH][ATTACH]58864[/ATTACH][ATTACH]58865[/ATTACH][ATTACH]58866[/ATTACH][ATTACH]58863[/ATTACH][ATTACH]58864[/ATTACH][ATTACH]58865[/ATTACH][ATTACH]58866[/ATTACH]
