Thank you Renzo
I take note of the RTC version, just a quick question, will the pump auto start on low level and auto switch off on High level. My solar pump is located in the field approx 8 km from the house, the reservoir (5000 Liter) tank is 1km from pump, hence the request to auto start and stop. I cannot visit the pump on a daily basis and there is not internet or cell reception.
I thank you for your kind assistance
