Ecobee premiun + HRV

[GECR21989]

Hi all,

I'm switching from a Lennox M30 to an Ecobee Premium in my home but am facing an issue since the Ecobee can control only one ACC at a time.

Equipment:

Furnace
HRV
Humidifier

Wires:

ACC1
ACC2
DH
C
G
W
Y
R

I wired the 2 ACC to the Ecobee, but I'm wondering how I can control the dehumidifier. I still have the PEK+ available. An Ecobee customer support agent told me I will only be able to control ventilation or the dehumidifier. Do you know any workaround? What are the cons of leaving the DH wire disconnected?

It is now possible to control 2 accessories with the Ecobee Premium.  See this post,
