More likely, people responsible for them do not understood how to operate them. rather than a system issue. Like in our field, old habbist die hard and change is not a commonly used vocabulary word When I first came onboard at WCU I had quite the challenge with the building maintenance folk. Our system is now working within design parameters and the stability is good. I still keep a watchful eye with my guages. Year round Temp range 70 +/- 4 Humidity 45% +/- 7 There have been a few minor mishaps but that was when the system was not monitored properly. Most of the systems fighting is due to doors and passage ways being left open. (ahhhh the faculty and students) I strongly suggest you ask for the "HOBO" report for the system. This is a functionalty reporting printout for the temp and humiodity ranges of the sensors throughout the building. It is really good analysis tool that your system should already have built into the computer. Printout parameters can bs set for day/week/month/ time ranges etc. One of the percular things that took me a while to grasp is that the heat can actually be on during the summer and the cooling on in the winter. This apparently has to do with the system working to maintain a status quo throughout the building. A waste of energy(?) perhaps, but our building did get a "green" designation.

My college has 100 pianos that I tune frequently. The majority are tuned 4 -6 times a year. Of course, concert work is done a lot more frequently than that but, the concert instruments also have Dampp Chasers on them which helps tremendously. The pitch and humidity swings are kept to a minimum. Otherwise, with the rest of the building, humidity swings were horrible!!! In August, it would be 65 %+ RH. October 35 %, December 18-28 %. January through March, 14 %-20 %. Of course, tunings are all over the place. These past 18 months, the CFAC (Covenant Fine Arts Center) was closed for remodeling. They redid a complete renovation of the entire CFAC. 18 million bucks worth. Part of the building opened up in October at which time the RH averaged 35 %. Granted, it just opened so they were getting used to adjusing everything. We encountered the same problems Paul, one room was 80 the next was 65 degrees. Supposedly, they spent quite a bundle on a new HVAC system. This past Wednesday and Thursday of this week, it averaged 22 – 26 % RH. One room was 19 %. So much for a new HVAC. I think they’re either over rated or the people responsible for them do not understood how to operate them. ?

It's at 45% this morning and has stayed between 39 and 45 for a month now! I'm a happy guy! Super cold snap and snow in a couple days, so we'll see if it can handle it.
