I think the right set up will definitely improve your Stienway D humidity situation, but it must be monitored, and the Humidistat position adjusted until it levels. Ask Ruth & Webb Phillips. The only place I found the D chaser bad was in a church where they turned off the heat during the week. The Humidistat thought the air was too dry and cranked out constant humidity into 35 - 40 degree air. The action stopped working, condensation etc., a real mess. Fortunately the owners called me fast and we unplugged the system. After they built a new church and now keep the heat 55+, the system has worked beautifully. Roger Hayden, RPT
