Don't know what a wall control is but would need two relay one for each devise light & wall control. PROBLEM
if furnace has a multi speed blower heat runs at a lower speed than ac to make this work without frying the blower motor both heat and ac have to run on the same high speed and might have a cold draft in heat if heat is satisfied and fan is running.
Relay looks correct wire both relays in parallel.If
Correct voltage relay coils.
Why not put the hrv on a timer or indoor air quality control.
