I have a brand new carrier 4-ton 15 SEER heat pump that was just installed on Monday. This morning I woke up and found the heat running around 6am. I got to work and my wife called me and said the heat was still running. After reviewing everything we found the following:
1. The "Aux heat" indicator appeared on the thermostat display
2. The air coming out of the vents was only slightly warmer than room temperature.
3. Thermostat heat temp was set to 77 degrees
4. The air handler did not shut off for hours all morning, we had to manually turn off the system at the thermostat.
5. Overnight temp was in the 40s and 50s which is why the heat was running.
6. After hours of running the heat, the temp was up to 77 when I got up this morning, but hours after this while at work my wife called and the temp actually dropped by a degree, so it was getting cooler not warmer.
We called the installer back and they sent someone over to check. Of course after they turned the system back on it worked fine and they couldn't find a problem. They probably think we are idiots and mis-configured the thermostat. It has worked fine as I programmed it up until this morning, and I'm a technically minded guy and familiar with HVAC and thermostat configuration, so I don't think its a mis-configuration on the thermostat schedule settings.
We got a new honeywell 7-day programmable touch screen thermostat. Its the VisionPro 8000 model.
My question is this: Could there be a setting the installer did not configure properly? I could go through all the installer configuration screens on the thermostat and see what things are set to. But to be honest, I don't know what configuration settings work with our heat pump. So if something was set wrong, I wouldn't know.
We have the carrier performance series 15 SEER outdoor pump, and a matching indoor air handler. If anyone knows what settings I should be using, or could point me in the right direction, I'd appreciate it.
