No
network detected if a Master in a multiple heater installation
‘P’ alternating with ‘cc’ = Pool sensor short circuit
‘F’ alternating with ‘oc’ = Heat Exchanger Flow sensor open circuit
‘H’ alternating with ‘oc’ = Heat Exchanger Combustion sensor open circuit
‘H’ alternating with ‘cc’ = Heat Exchanger Combustion sensor short circuit
‘F’ alternating with ‘cc’ = Heat Exchanger Flow sensor short circuit
‘Err’ alternating with ‘4’ = Pool potentiometer open circuit
‘Err’ alternating with ‘5’ = Pool potentiometer short circuit
For all of the above. Turn off, correct problem and turn back
on again and the display and operation will be normal.
