Anyone familiar with these products? I have more heating cable amperage than the tstat can handle so they make a "sunstat C3 relay" module that communicates with the thermostat so one thermostat can control multiple cables. I am a bit unclear in the wiring so I just want to double check. So in the case of using these relays, it appears the tstat still gets line power, but the load wires just get capped. A comm wire goes between the tstat and the relay(s). The relay gets line power and the load/heating cable. Is this correct? Say I have two cables per tstat. Do I use two relay modules or can I run one cable off the tstat and the second off a single relay module?
