What to do if the liquid level controller of the geothermal deaerator is always broken?

Our company operates 20-ton*3 steam boilers, and the deoxygenation effect is not very good. The reason for this is that the temperature of the water exiting the deoxygenation process is kept too low, at around 70°. During the deoxygenation process, when the water temperature rises to 95–105°, the large fluctuations in water level cause the level controller to control the deoxygenation pump to start frequently; as a result, the level controller keeps breaking down (1: it fails to stay stopped, 2: it fails to start, 3: it starts and stops repeatedly). A float level controller (Shanghai Cedar 02) was used. It was necessary to lower the temperature to 70°, and of course the deoxygenation effect was poor. I would be very grateful if the experts could take a look and offer some guidance. :):):)
