My Mastertemp 400 will no longer auto start with intellitouch spa setting.
It use to be automated start when SPA switch is turned on with remote now it wont
Now I can only get it to manual start and stop after I use the fireman switch jumper - disconnected the fireman switch with intellitouch.
display at startup 128 r=9
"heater off" 30sec setting is AD0 and SP1
When I connect the fireman switch wire the heater will not work. it just display 128 r=9 then display goes off.
Would like to get the heater to go on auto again. Please help. Thanks.
