Tunze 3155 Start-up error
I just bought a used Tunze 3155 and upon set-up it failed. Seller told me that it was perfectly working before he shutdown his tank and removed all the equipment.
2 LEDs - the Too high and Too low lights are flashing at the same time with a continuous beeping alarm. I opened the controller but there is no apparent water damage. I also cleaned the solenoid connections and checked the power adaptor (correct one). Not sure what is wrong. Please assist. Is Roger Vitko onboard? Thanks!
