Product Details: Max Working Pressure: 10 Bar Relay Capacity: 220VAC 10A. Overload Capacity: 200%. Frequency: 5 times/second. Temperature range: -20℃ ~ 80℃ Accuracy: Better than 1% FS. Pressure Connection: G1/4. Measuring media: Water/oil/gas. Wires Connection: Power(red and blue),Output(black and white). Protection: Reverse polarity and short circuit protection, Water shortage protection. Reference for setting parameters: 1. Stop pressure H (upper limit) : pump head /10-0.5(such as: 40m head set to 40/10-0.5=3.5). 2. Starting pressure L (lower limit) : 1 floor 1.2, 2 floors 1.5, 3 floors 1.8(add 0.3 for each more floor, the controller is on the first floor). 3. Water shortage pressure F: generally the lower limit starting pressure value -0.5. Default values L1.5, H2.9, F0.6, suitable for most applications. Maximum difference between H and L: 9.5bar Minimum difference between H and L: 0.5bar
