1. Kanitti Investments Ltd Description The DIFT2 is a differential thermostat solar controller designed specifically for the domestic solar hot water market It continuously monitors the temperature difference between a tank sensor and a panels sensor and switches an external AC hot water circulation pump to facilitate optimal overall system energy efficiency Boil Protection Water circulation is cut out at a tank temperature of 75 C to protect the tank from boiling and minimize the risk of scalding Freeze Protection Water circulation is initiated when panel temperature drops below 4 5 C and stops when panel temperature reaches at least 7 C to ensure water does not freeze in the pipes For closed loop systems freeze protection can be disabled factory setting Status and Fault Indicators The two status lights visible on the top lid provide information regarding faults and normal operation of the controller The following table summarizes the status and fault indications Technical Specifications Red Green Indication Light Light Standby mode pump off On Off Optimal temperature reached boil protection Panel sensor disconnected a slow Flashing fast Panel sensor shorted T l slow fast Faulty Panel Sensor Operation Factory Setting In case the panel sensor is faulty disconnected or shorted the controller will activate the circulation pump for a period of about 40 sec2.
