The RESOL thermostat compares the temperature measured by a sensor with the preadjusted switch-on temperature. If this temperature falls below the adjusted switch on value (heating operation) the relay switches on. If the temperature is exceeded, the relay switches off. Depending on the adjustment of the switch-on and switch-off temperature, the controller operates in heating or cooling operation. Depending on the application area, all Pt1000 temperature sensors from our product range can be used. Electronic temperature controller (thermostat) with combined LC display for indication of the actual temperature and adjustment parameters (menu-driven). One temperature sensor from our product range is required.
