TECHNICAL HELP

HUMIDIFIER

NOTE: Two terminal choices (HM1 or HM2) are provided for humidifier control. When the humidity setting is higher than the room humidity: HM1 turns off the humidifier when the call for heat ends. HM2 powers the humidifier an additional 30 seconds after the call for heat ends to provide slightly more humidity output. Most installers will use HM1 unless they feel more humidity is desirable. 6
