Just got a california cooperage Model 105, 2001 i think No manual, have searched all over the net and cant seem to find Heater is not heating Seems to be stuck in economy (EC) mode Have it currently wired for 110 was going to rewire for 220 Have tried many diff button combos (heater then light... ) to change the current mode to Standard (ST) just wont go " title="Sad" /> Seen many "F" settings, F1, F2...6 FC, FA.... not sure what these are. Help please! Thanks Dave

I have a model 105, and encountered a similar problem. User manual is here: http://team.maaxspas.com/manuals/Owners... 20Coop.pdf) But solution is not in the manual because the 105 doesn't have a EC mode. Strange behavior was due to the fact that I had replaced the control board with a newer version than included the economy function. Can't remember where I found the solution, but what worked for me was to push "Temp" and then "Light" simultaneously. Hope that helps, -- Dom
