Page 10: Parámetros Para El Instalador (Botones De Acceso Mode & Set & -)
Para la selección de los valores de dP, el PWM está dotado de un sistema de limitación que se activa cuando se configuran setpoints de presión inferiores a 2,0 bares. En este caso, dP se limita a 0,5. Por ejemplo, si SP valía 3,0 y dP valía 1,0, después que Sp se ha colocado en 1,9, dP valdrá 0,5. Por el contrario, si dP era inferior a 0,5 (por ejemplo valía 0,3), durante el paso de SP = 3,0 a SP = 1,9, el valor de dP no se modificará. -

Page 12: Ft: Configuración Del Umbral De Flujo Bajo (Valor Preconfigurado 15)
La ventaja de seleccionar un dP diferente de cero es que se puede redimensionar el caudal si hubiera pérdidas en la instalación y permitir un ahorro de energía, pudiendo funcionar la electrobomba a bajas revoluciones cuando los flujos requeridos son bajos. Los posibles valores configurables de dP son de 0 a 1,0 bar, salvo limitaciones automáticas (véase párrafo 6.1.1.1). -
