Yes, in my attached picture the red and block wires would connect to the Ecobee ACC terminals.

The 3 wires on the right are for the interlock, but because you're using the PEK extender kit I would just leave them connected.

I couldn't determine how to attach photos, but I've included a link here:

The current controller uses a three wire setup and has a red, green, and blue wire attached.

HVAC Help / Ecobee Premium- HRV Wiring
Last post by ADirtyGrandpa - January 14, 2026, 11:03:40 AM
I have an Ecobee premium and I'm looking to connect our HRV to it. 

I've seen similar posts and I understand the Ecobee can only control one speed (I will likely wire it to HI). 

I'll attached photos of the thermostat wiring, HRV wiring, and furnace wiring. 

I'm hoping someone can help provide direction. My HRV has 6 wires which is where I'm confused. I'm thinking I can wire to ON, RED (with a jumper), then to HI? I'm not sure what to do with the additional cables. 

Thank you!

Either as long as they have CAN/ULC-S642 certification.

QuoteClause 6.9.6
When a jointing sealant is used, it shall be certified to CAN/ULC-S642 and shall be applied to the male threads of a metal pipe. Tape shall be stretched and applied in a clockwise direction, with a 50% overlap leaving the first two starter threads bare.

I think a flex connector should only be used when there is an appliance to connect it to.

Any length nipple would be approved.

Where are you referring to 2 gas connectors ? Is a cabinet still considered a wall ??
Quote from: Admin on January 07, 2026, 10:10:42 PMIt's hard to tell but if that's two gas connecters connected together it's probably against code that they are passing through the cabinet.

QuoteClause 6.21.2
A gas connector shall
a) be protected from damage;
b) not pass through a wall, floor, ceiling, or partition;
c) be connected to rigid piping or tubing located in the same area as the appliance; and
d) comply with Clauses 4.5.2 and 4.9.1.

I would remove everything and install a nipple and cap into the shut off valve.

QuoteClause 6.12.1
During the period when an appliance is not connected to an outlet of a piping system, the outlet shall be made tight by means of
a) a plugged valve; or

b) either a cap or plug made of material compatible with the material of the piping or tubing system.


1. If I remove the flex hose can I cap the silver flare connection is that allowed ? The silver connection is connected to black pipe
2. If I cap after the shutoff is there a rule of how long the pipe should or should be
