Momentum DF220 Digital Pressure Switch, 0.1–10 Bar, Precision Adjustable

Product description

The digital pressure switch features dry-run protection, which protects the motor against dry running; this function can be enabled or disabled. The activation delay is 2 minutes.

• The H button is used to set the upper cut-out pressure of the booster pump. Simply use the up/down buttons to set the desired cut-out pressure in bar.
• The L button is used to set the lower cut-in pressure of the booster pump. Simply use the up/down buttons to set the desired cut-in pressure in bar.
• You can set a delay time to prevent the pump from cycling on and off frequently. Press and hold buttons 1 and 2 simultaneously for 3 seconds to display the value n03 — this means the pump will wait 3 seconds after reaching the set pressure before acting. You can increase or decrease this time delay as needed using buttons 2 and 3.
• If no action is taken on the settings screen for 3 seconds, the current settings are saved and the screen exits.
• Turning dry-run protection on or off. Dry-run protection comes enabled by default from the factory. If the motor operates at a pressure lower than the lower cut-in pressure set on the pressure switch, the motor is protected after 2 minutes.
• Press and hold buttons 2 and 4 simultaneously to display F01 or F00. When F01 is shown, dry-run protection is active. Press and hold buttons 2 and 4 again to switch to F00, disabling dry-run protection.
• When the digital pressure switch activates motor protection, an E-F error is displayed on the screen. Press any button to restart.
