Yes, you are correct, except that the linked product is actually the
now discontinued RCS model.  It can be simpler than that, however.
You can install ELK-M1ZTSR modules and connect them to the ELK-M1G
controller.  Where the pump / light / heater controls are add an
ELK-M1XIN input expander and ELK-M1RB relay board.  You can read
temperatures as well as light, valve, pump and heater operating
status into the ELK-M1XIN as dry contact or analog (0-10V) inputs.
You can operate everything via relays on the ELK-M1RB.  The input
board has 16 zones and the relay board has 8 outputs.  You can have
multiple boards as needed.  They all connect to the M1G control via a
single CAT5 cable.

The relays on the M1RB are rated for 10A @ 125VAC or 7A @ 30VDC.  To
control heavy loads you can use an ELK-9100 or any high-current
contactor from another manufacturer.
