When I find a damppchaser without a humidistat, I always advise leaving it unplugged until such time as a humidistat is installed. I explain that it is like having a furnace with no thermostat. I have found too many church pianos 50 or more cents flat in the dead of winter because the damppchaser was still plugged in. The extra tuning required to get the pitch back on track equals or exceeds the cost of installing a humidistat. I refuse to install one without it! Ray T. Bentley, RPT Alton, IL
