 gotta say make a very unique gear that's not one to run. Going to see what's causing it to drop out. It's been reset a couple of times and keeps tripping back out. This definitely is one of the nicer ones I've seen. It's really dirty. Checking our set points. So far this thing's pretty user friendly. Currently it looks like it's active set point. It's 50, supply temps 36, like it was when we got here. Outside air was 22, discharge was 32. Cold coil 22, room 78, system on heat. It's pretty much the same thing both times. Both times it looks like it just did not bring on the heat. It looks like we're in low fire, but you can see we've got one manifold right here. It comes down to that one. High fire would be this bigger one. We've got more, it's pretty much the same thing over here. So we're running in low, getting in high. Just need to find out why it's not wanting to supply set point 50, supply temp 36. So why are we not going into higher fire? I don't get that. Okay, just brought on the bigger. Let's see if it's something malfunctioning when that's running. So far everything looks fine. Well, interesting here. We're set for 69, room temperature is 84. Stats set for 69, high temp set point, active set point 50, supply temp 50, room reset 90 to 50 minimum maximum. Fan speeds 100%, supply low air alarm. When supply is below 35 degrees, alarm delay 300 seconds. Lockout cooling when outside air is below 55, two degree differential, heating lockout when it's above 70, set point 55, cold coil temperatures. Basically what we came up with, it was sensing temperature on the inside. It has a stat that reads the room temperature down there and that's where it was doing its outside reset at based off room temp. Problem with that is the lowest temperature this is allowed to go down to discharge temperature was 35 degrees for maximum of five minutes. If it fell below that it'd go out on low temp alarm. Well, the machine wasn't programmed smart enough to know that, okay, yes it's 76 degrees inside in the room which was what we were earlier, now we're only 69 but it was 76 degrees and the air was set up from like say 50. It's figuring I don't need heat, why should I run heat? But even though it was programmed to shut down when the duct temperature went below 35 degrees it didn't do anything to keep that from going below it. So it was just focusing on that room temperature. So what we ended up having to do was coming in and actually going to our set point and going down to our source and putting it on local. So now I've told it to go ahead and try to maintain a 50 degree discharge air temp with a minimum of 48 whereas before it was 50 and now it's able to pretty well hold the temperature like it's supposed to. It's just one of them goofball things. The supply air now is at 55 and it's doing a pretty good job whereas before it'd get down below that 32 mark and it did nothing to try to maintain it and after five minutes it'd go into lockout but there's our outside temp, there's our cold temp and then our room temp. So it's supply air is 57 so it's actually maintaining a decent temperature now. We're gonna try this first, see how that works. That was pretty much a recommendation from the factory. Really wasn't a whole lot of other things we could do besides lowering the temperature that it would lock out at. And last thing you want there is is for there to be a day where they're not here creating all that heat and you bust all your pipes inside when you're below freezing. So that's what we got. We went ahead and got the filters taken out, getting those cleaned out down below because we can't really do it up here and then we gotta get some new air filters for it but pretty nice machine. It's got an actual heat exchanger instead of direct fire and it's responding like you would figure it would do. Also has deep modification, got hot gas bypass up there. Pretty neat system. This is the first one I've seen like this. It's got a free drive on the motor. So it's pretty nice. Well, hopefully you didn't get as bored as my dog did here. Here's a little background on this call. Basically it's a production facility that runs obviously 24-7 and they need humidity control, heat, cooling, both in all seasons. They have full-time maintenance people that can switch the machine over from local to remote thermostat. The remote thermostat would be more useful when they're running the air conditioning so that they can maintain the temperature down below. This is bringing 100% outside air in and no return air coming from inside the building at all. So they're gonna need to use that inside thermostat when it's in cooling mode but not necessarily when it's in heating mode. In the wintertime they're gonna maintain a 50 degree discharge temperature just like a traditional system would be so it's not a huge deal and don't really need much of anything else so that temperature's gonna hold pretty good there. But when you're in the cooling season that's when they're gonna have to have that a thermostat.
