Outside air is accurate and I don't know of any lockouts related to that. After digging through it again, It looks like it gets DAT from the bypass and will broadcast that to the 4 VAV'S. (Doesn't...
I posted a question in Controls tech to tech chat on 12-27-22. Looks like it's had no views. Did I post it in wrong spot. TRANEDOG
Finally following up on old posts. After a month of trying to find a replacement "that would fit" and even the rep' to the manufacturer of pump (in Germany)..No help. We replaced the units with Space...
One of the systems on the SC has only 4 zones. BAS set point is "out of service". Thumbwheels are locked out, so I assume it looks at the "callers" in VAS? Set for 2 "opposite callers" & 1 "strong...
Daikin Air to water heat pump for radiant floor heat. EDLQ054BA6VJU1 The pump is failing and is obsolete through Daikin parts rep. Anyone found a suitable replacement??
I have a Microtech III in a McQuay unit that's not responding to the Johnson Controls BMS telling it what supply temperature to run. This controller was replaced this past summer because the old one...
Its about 3 or 4 yrs old and does have those red boards in every unit. To make sure i understand correctly....i would disconnect the comm link then connect to the red board via a USB/PRINTER cord...
Thanks for the info and ideas. I had mapped out the comm link several months ago and there's 7 units 22 vavs and 7 bypasses. Theres and EOL device on each end although Ive been told you really only...

Titan paint booth heater with Maxitrol components. Amplifier A1494 sending out sporadic dc volts 0,6,17,0,2,5,3,15, and so on. I thought it should rise and drop somewhat slowly to maintain SPRAY set...
Ive found 5 systems, mini splits that I had to replace the line set because of multiple leaks in the copper line set. One of our techs says he heard its because the lines aren't being insulated tight...
Thanks for input. It had 4---30 min defrosts several weeks ago and guys have kept adding more. When i saw it yesterday it had 8 defrosts- some 45 min, some 1hr, some 30min. (I know that's messed up) ...
Defrost clock works. Fan delay functions. Heaters work. Not certain if defrost temperature termination works. Sight glass stays solid. Its at a chain diner restaurant. Its been a couple months and a...
Thats not a bad idea. Thx. Im betting its one of the regulators. Going back next week when lift gets on site.
There is shut offs at each heater, but they are after or downstream of regulators for each heater so i guess i need to keep the psi low. I had to schedule a boom lift for Tuesday next week. I also...
Looking for creative ways to locate a natural gas leak in a huge manufacturing plant with alot of gas pipe and 30 tube heaters. No one smells gas, but their bill was $4000.00 this summer. Gas co came...
