Hi all
I have a heating problem tub will not heat the box is an iq 2020 when I reset the power I get 3 led lights briefly
lim
htr
controller unplugged
then the only one to stay lit is the lim this is a steady green
I understand from some research that the lim indicates that the sensors are working correctly
and I should have the HTR light on red and that the controller unplugged should be out I guess they come on briefly as some form of power on test to prove they are working then I should only have the lim lit green and the HTR lit red
my problem is I have no HTR lit any one got any ideas
many thanks
