I like to use the +12VDC from E2RH (terminal 4 and 5) to switch 3 solid state relays (SSR-40DA) connected to E2RH Timer A relay (terminal 7 and 8). The SSR relays will send 120VAC output to heaters when switched. Each relay draws about 7mA for switching. Is this possible and do you have a wiring diagram?
