Installation Tips
- If your pump does not have a built-in check valve, install one in front of the pressure switch to prevent frequent on/off cycling.
- If the pump cycles on and off when the tap is open, adjust the H valve to a higher setting.
- If the pump runs continuously without stopping, lower the H valve setting.
- If the pump does not start, raise the L valve setting.

Frequently Asked Questions
Q: What types of pumps is the A01R digital pressure controller switch compatible with?
A: The A01R pressure controller switch is compatible with virtually all pump types, including water pumps, oil pumps, and air compressors. Its 0–10 Bar working pressure range and 1/2-inch interface make it highly versatile for residential and light commercial applications.
Q: Does the digital pump switch protect against dry running?
A: Yes. The A01R switch features built-in dry-run protection. It automatically shuts off the pump when water shortage is detected and restores operation once water supply is available, helping to extend the life of your pump.
Q: What is the maximum pump power the switch can start directly?
A: The A01R provides an active 220V AC output and can directly start pumps rated up to 1.5 kW without requiring an external relay or starter. For pumps above 1.5 kW, an external contactor is recommended.
Q: Is the EU plug compatible with my country's outlets?
A: The EU plug (Type C/F) is compatible with outlets in Germany, France, Spain, Italy, Indonesia, and many other countries that use the standard European round-pin socket. Please verify your local outlet type before purchasing.
