Good afternoon,
Just replaced the circuit board on my Aquacal T135 heater. This was due to no power getting to the control display. After putting it in, everything looked good until the compressor got ready to turn on…then everything shut down and the OTA system lockout message came up. I ordered the ECS0275 sensor, removed the old one, inserted the new one and tightened the clamp. The new one comes with two wires but it also has a separate two wire adapter that plugs into that ( I assume) and then on the end of it is the connector that plugs into the circuit board. But still some issue…system shuts down with OTA mussage saying to contact service dpt. The display temperature on the screen shows spa water at 90 degrees which is dead on based on our thermometer in the spa. I have shut down the system multiple times and most recently reset to factory default but still the same issue. Any ideas?
