Energy meter with a two-line display. Temperature input PT1000 (2-pole). Micro-SD card for storing measurement data. 3 buttons for easy operation. 1 relay contact for controlling additional consumers (e.g., heat pump). RS485 / CAN communication. Current transformer connection via RJ12 plug (transformer 80A included). Smartfox Pro Light is the solution if you need a compact energy management system for water heating without online monitoring. A real-time clock is implemented in the software, allowing for a forced release for the heating element to be programmed. This ensures hot water production even in bad weather. With the PT1000 interface, a minimum temperature to be maintained and a maximum temperature to be reached only with surplus energy can be set.
