Have five 12 ton Aaons for indoor growing spaces and have modulating gas reheat which works out great. Also have electric heat as a backup when the system is taxed heavy.
An ERV is not a dehumidier. It is a heat exchanger. Condensation can form in the ERV if the dew ponit of the outside air is above the temperature of the indoor air. Let's say your indoor air is 72 degrees. Bringing in unconditioned outside air with a dew point greater than 72 degrees guarantees condensation. Examples would outside air higher than 72 degrees and raining, 85 degrees outside and relative humidity above 65% or 95 degrees outside and a relative humidity above 50%. A ventilating dehumidifier would be a better choice for humid climates.
Modulating gas re-heat is your friend. AAON does it really well

Can you do a video with a breakdown of the controls and valves used to make this system work?
awsome , video,, just arrive here 2 years late
So basically without the reheat coil. DX coil alone fail to control humidity.
hi.how about energy consumption?how about using ERV for dehumidification? is it applicable

Great!!
Why can’t we use the heating coil to reheat the air instead of adding an extra reheat coil ?
I think I just realized why.. it’s because it’s not efficient to run boilers during summer just to reheat the air, oui oui ?
Funny, we kick ass using ACs and Electric Resistance heat, the game is over and Engineers are OUT!
long, too boring
