The H8908ASPST Humidistat provides manual low voltage control of Honeywell TrueSTEAM Humidifiers in central heating and air conditioning systems. They have a SPST, snap-acting, dust-proof switch and are designed for wall or surface duct mounting. When purchasing a new Honeywell TrueSTEAM humidifier, a humidistat is included so purchasing this manual humidistat is not required.
