Check if there is an INVERTER device or other special electronic or wireless device operating in the pump station area. If so, it is very likely that during its operation it creates strong electrical noise which prevents the proper operation of the receiver.In this case, the receiver must be removed from the source of the noise and placed in a separate metal box. You can purchase a special network noise filter for best results.

When both of the above problems exist (long distance and lack of visual contact), then the only solution is to install an intermediate Transponder station at a third point which has the best possible visual contact with both the tank and the pump station.

When this happens, you must thoroughly check the connection between the antenna and its cable by unscrewing and re-screwing the special connector on the cable that connects the antenna to the receiver or transmitter. It is also a good idea to check the power supply of the transmitter and receiver (you will need a digital multimeter) to try to identify faulty connections.

There is probably another wireless remote control with the same code operating in the same geographical area. This should not happen (it is not allowed to arbitrarily change codes on the devices), but if it does, you should ask us for a new code for your system to eliminate the problem.
