Press the bottom of the humidistat in to engage the base hinge. Mount the humidistat by hooking the two hinges at the top of the back cover to the raised edge at the top of the base bracket. 6–19 for different wiring configurations.ħ.
Using wire nuts, connect the low-voltage wire to the leads on the H8908 humidistat. The remaining two red wires are only used with electronic humidity controls.Ħ. On HE365 fan powered humidifier models, only the two yellow wires are connected to the control. On multispeed blower applications, do not wire the high voltage side of the transformer to the same power source that services the furnace blower.
If not using a current sensing relay, sail switch, or air pressure switch, the humidifier must be energized during blower motor cycles for proper operation. Select models of fan centers include humidifier taps so the current sensing relay, sail switch or air pressure switch is not needed. Make wiring connections according to humidifier (or dehumidifier/ventilator) instructions, if available otherwise, see typical wiring diagrams in Fig. H8908A/B HUMIDISTAT H8908C/D DEHUMIDISTATĭisconnect power before installation or servicing.Īll wiring must comply with applicable local codes, ordinances and regulations.
