REPLACEMENT RELAY FOR FAN CONTROL CENTER
90-112 THRU 90-130 FAN CONTROL CENTER
When the fan relay transformer is energized and the thermostat completes the connection from R to G the fan relay coil energizes. Line voltage power applied to contact common path travels to selected blower speed tap. Additional terminal Y and W are isolated tie point terminals to connect thermostat wiring to compressor and furnace (if required).
NOTE: Record the lead wire color with its corresponding terminal for future reference. Unused transformer input leads must be insulated.
* Black is common with respect to transformer winding, not external circuit.
