Tekmar shows the 518 as the replacement for the 508, but I feel like my 6-wire setup won't work with this?

Any insight on how to wire to the new thermostat?

    The 518 will wire exactly the same as the 508. The only difference is the floor sensor terminals on the 508 say "sensor" 1/2, on the 518 you'll use S1 and Com.
