3.10.1 Operational mode
There is a choice of four different operational modes:
• 1 adjustment cycle Only one level-sensor input is evaluated. As soon as sensor 1 registers too low a level the switchable socket outlet with the function Water 1 is switched on. When the nominal level is attained the socket outlet is switched off again.
• 2 independent adjustment cycles The two sensors can be used independently of one another. As soon as sensor 1 registers too low a level the switchable socket outlet with the function Water 1 is switched on, and the same applies to sensor 2 and Water 2. In both cases switch-off occurs when the nominal level is attained.
• Min/Max adjustment The two sensors work together to regulate a single water level. Sensor 1 functions as the maximum switch, sensor 2 as the minimum switch. As soon as sensor 2 registers too low a level the switchable socket outlet with the function Water 1 is switched on. Then when the water level reaches the setting for sensor 1 the switchable socket outlet is switched off again. The switchable socket outlet Water 2 switches on and off in line with Water 1.
• Water change At pre-set times water is drained off (the switchable socket outlet with the function Water 2 is then switched on) until sensor 2 signals the minimum water level has been reached. Thereafter Water 2 is switched off and the switchable socket outlet Water 1 is switched on until the water reaches the level set for sensor 1. -> Sensor 1 signals that the tank is full again, sensor 2 indicates when sufficient water has been drained off. The switchable socket outlet Water 1 turns on the fresh water supply, Water 2 turns on the outflow. After selecting this operational mode the timer that is to determine the timing of the water change must be selected. Don’t forget to program the chosen timer accordingly in the appropriate menu (set the switching period to Event start there, see 3.13.3 Clock timer). The water change will then be started at the time set there.
