I have two Fibaro FGS-222 relays controlling a heat pump. I would like to be able to operate the heat pump manually by attaching switches to S1/S2 in case the controller stops responding - currently I can only control it remotely via the home automation.
I'm confused about what S1 and S2 do. Can you control the relay both remotely (Q1/Q2) and manually (S1/S2), each independent of one another - i.e. turn the pump on or off by either method; or are S1/S2 master switches, as the manual suggests - i.e., if S1/S2 is off, it stays off and you can't turn it on from Q1/Q2? Also, if you have turned the pump off remotely, via Q1/Q2, can you turn it back on using S1/S2? Or will turning S1/S2 off and then on again simply "enable" control via the home automation controller, but remain in the off state until turned on remotely? And does this depend on configuration parameters such as parameter 13, and/or the type of switch (toggle/momentary).
I've read around trying to understand this, but I don't find the documentation clear at all.
