HeatPumPro has a clear LCD display that makes it easy to see what's going on with the control panel. Here's how to find each setting, and what they mean.
This is going to be your main screen when you show up and look at the HeatPumPro. So if you’re looking at the first part of this on the top there, it’s gonna have HVAC, and then it’s gonna have a condenser and an air handler. What this is showing you is what we’re actually outputting to your equipment. So in this case, we’ve got a W1, W2; Y1, Y2 on the condenser; Y1, Y2 on the air handler; a G and an O, that is actually getting outputted to the equipment. So it’ll actually show you exactly what our panel’s doing, and what your equipment’s actually receiving from our panel. It’ll speed up your troubleshooting to see exactly what we’re looking to get out of the panel.
When you look just underneath that, you’re gonna have an OAT and an LAT reading. The OAT is gonna be your outdoor air temperature. If you guys just have a conventional gas furnace system with air conditioning, you do not need to run that sensor outside. But it does still need to be on the panel. If you don’t have it attached to the panel, it’s gonna read 0 degrees on your outdoor air, and it will not allow for the operation of the condenser. All they’ll get is a fan, because it’ll think it’s too cold outside to run the air conditioning. Right next to that, you have your leaving air temperature protection, LAT, and that’s what it’s actually reading in the plenum of your ductwork.
Just to the right of that, just underneath, is a compressor lock. What you’ll see here is if you stage up and you overheat in the equipment or if you’re starting to freeze up the coil, you’ll see a compressor 2 lock pop up first. It’ll drop out your Y2 or W2 signal depending on what you’re in. And then if it’s still too hot or too cold in the ductwork, it will drop out that compressor completely, and just run the fan until that temperature comes up 10 degrees in the ductwork.
Right underneath that, you’ll see a purge time. The only time you’ll see anything here is at the end of a call. If all the calls are satisfied on the panel, you’re gonna see a post purge time. What that’s actually doing is running our pump for X amount of time, and that’s field adjustable, it’s usually 5 seconds per damper. It’ll run our pump for that amount of time after the calls have satisfied to make sure all your dampers are in the open position at the start of the next call. What that actually allows is for the soft start of the motor, so you don’t get ductwork popping and that kind of stuff when the zone starts calling. As that zone calls, it will start closing off the dampers.
And then over on the left there, you’re gonna see zones, and this will display any zone on the panel that’s actually calling at that time. So it’ll have zone 1-4, or whatever zones are actually calling, will be displayed in that window there. And then it’s also gonna have your zone weight, which is the amount of ductwork that’s actually open in the system at that point.
