I want to fit a Texecom Odyssey5 compact bell box to a Gardtec diamond 500 panel.
I understand the connections are: SAB tamp to C in bellbox (tamp)
Bell- to B in bellbox (bell -ve)
Bell+ to A in bellbox (12v +ve)
Bell hold- to D in bellbox (0v)
Strobe- to S in bellbox (strb -ve)
Strobe+ not connected
What I don't understand is the difference between Bell- and Bell hold- in terms of operation?
