Hi Gang,
I'm designing a RA2 system to control some Infratech heaters via their home control panel and LMJ-5T-DV-Bs.Application Note #655 Says I need to use a LVS Controls EPC-1-D to integrate. I'm assuming this is to serve as a cutoff on the low end not being low enough to fully turn off heaters. This is based on the other threads regarding this combination.
My question is why the EPC-1-D and not just a relay? The EPC-1-D is expensive ($200 plus) and seems like they are just utilizing it as a simple relay.I can't see why an emergency lighting control is the right part for this.
It looks to me like you would just connect the 120v switching output of LMJ-5T-DV-B to control a relay that would interrupt the 0-10v signal and accomplish the same thing.
Can anyone shed some light on this?
