The attic based solar sensor [thermistor] must be wired ÒIN-SERIESÓ [in-line] with the leak
detection floatÕs white wires [AS SHOWN ABOVE]. The float is a closed circuit switch. If excess
water should ever occur inside the PCS1, the float rises and the switch opens. In AUTO mode, the
LX220 interprets this open circuit condition as a cold attic and shuts the bypass valve off. The LX220
ÒSolar Sensor Service ReqÕdÓ light will then turn ON indicating a need for service.
