User canprogram a constant temperature instead of a sensor output also. Thesensor types are programmed at the factory for thermistor (KTY 10) types. ThePT 1000 sensor is recommended for high performance collectors such as<strong>Thermomax</strong> systems and will not be damaged during collector stagnation. PT1000 works fine in 482 o F range and survives up to 572 o F temperatures for ashort period of time. The KTY 10 tank sensor should be used in a conditionedenvironment and will not be permanently damaged up to 360 o F.Selection:S1S2S3Sensor 1 (collector outlet) selectionSensor 2 (collector inlet) selectionSensor 3 (tank) selectionDesignation:PT PT 1000 sensor (1000 O at 0 o C)KTY Thermistor sensor (2000 O at 25 o C)250 250 o F reference temperature- 4 - 4 o F reference temperature13
