WeilMclain Aquabalance Menus not working

xge1xge1 Member Posts: 1
I had a Weil Mcclain Aquabalance 155-C installed recently, and I just added the outdoor reset sensor this week. I am trying to access the menu to change which OTC curve to use, but I cannot get to it. I press the reset button for 5 seconds and and all I see is flashing diagonal lines, like this:


Is there a problem with the controller or am I just missing something? Thanks.
