If you know someone with a little electrical knowledge, have him find a
suitable relay with the proper capacity to run the humidifiers.?? A
Damppchaser system might use 5 rods, so maybe 180 watts or so.?? Look on
each humidifier unit and find out how many watts it uses.?? A relay would
work well to isolate the humidistat from the heavier current needed to
run the humifiers.
I just looked on Amazon and found a humifier that covers 1300 square
feet.?? It's 60 watts.?? So, probably you could use the humidifier with
the damppchaser without a problem.?? Unless you're running some big kind
of humidifier unit for a very large room.

James,
Good point about the capacity of the PLSS humidistat to support the electrical draw of the room humidifier in addition to its own tank and smart heater bar. I'll have to look into that further.
And yes, a higher capacity, stand alone room humidifier with its own humidistat would be preferable. This experiment was prompted by the fact that we found ourselves with a couple of small capacity room humidifiers that lacked humidistats of their own. It's a case of trying to "use what we've got to get what we want."

I think you should run the idea/experiment by the Dampp Chaser technical people because the humidistat was designed for use with their UL tested and approved configurations and not for other equipment. You most likely voided any warranty you had on the PLSS/Dampp-Chaser system. Although it may seem alright there might also be a fire risk because of the draw the unit is making on the circuit. For everyones safety and sanity I would purchase a larger capacity humidifier that has the proper sensors to turn it on and off and not piggyback on the PLSS humidistat.
One of the common causes of fires is the use of those little cell phone chargers people by at the dollar store. One of the upscale communities I tune pianos in had an entire home burn to the ground while the owner was at work. She used a cheap charger on her phone and went to work for the day. Because a wood burning fireplace was nearby the chimney help feed the fire with its updraft and the fire was too hot/out of control for it to get knocked down. We have excellent fire and rescue squads here that are ISO certified and with state of the art equipment.

Subject: Room Humidifiers Piggy-Backing on Piano Life Saver Systems
Greetings,
Here at CalArts we have a smattering of "techno-pianos." Unlike most of the other pianos in our inventory, we cannot put full humidity control systems on our MIDI-grands and Disklaviers, only drying rods and humidistats. It gets very dry out here, and for the heart of the school year.
So, we started using room humidifiers (Venta L45 Comfort Plus) in some of those rooms. VERY beneficial, but must be watered much more frequently than piano-specific systems.
In one of our classrooms, we have a piano with a complete PLSS on it. In that same room is a harpsichord (which seems to change pitch if you stare at it too long). We had a smaller capacity room humidifier on hand, one without a humidistat. (Since RH can vary 40-50% in a single day out here, we don't want a room humidifier operating without being humidistatically controlled.) As an experiment, we plugged the room humidifier into the PLSS humidistat's "Humidifier" side of things. The results after a few months are very promising. The harpsichord gets tuned at least once each week, and has been much more stable than usual. We were concerned that the room humidifier might need to be manually reset after being turned off by the PLSS, but that is not the case.
Has anyone else tried doing this? Or anything akin to it? Might there be any potential downsides?
FYI, y'all!
Alan
