Ah yes need to set the ERV to 'DRY' mode and select speed...thanks!

That attachment explains the speed configurations and has a NOTE to not use a main control with this setup.

The Ecobee replaces the main control.

Thanks that worked! but the EVR goes into minimum speed, is there a way to wire it to MAX? The wall control doesn't work now.

Try wiring V to ACC+ and R to ACC- or try the alternate wiring shown in the attachment.

Hey,

Just looking for some advice on how to wire my Venmar ERV130 to my Ecobee Premium with as a two wire accessory. I am not sure of what terminals I need to wire to ACC+ and ACC to have Ecobee set the ERV to on. Here are my terminals.. V, Y, W, C, Gf, G, R

Thanks in advance!

We are really stumped about our AC. They replaced the condenser outside unit and coils in attic 6 mos ago. American Standard 13 ton)  They left the old zoned thermostats (3 zones master bedroom area is main/master?? zone). They left the dampers, and the old control board up in attic too. We replaced  the condenser/coil when the outside unit would randomly not turn on thinking that would help. The blower in the attic would turn on fine.  So we thought maybe we had a slow leak in the coil and it was freezing over and that would fix it. But it didn't and now it's still happening with the new system the same thing plus more stuff.

Sometimes the compressor and fan both work fine whole system is great. Sometimes it's hot in random rooms where the thermostat calls for 70 and it will be 72. But the other two zones are holding temp. Monday night it was the bedroom zone not holding temp and then yesterday it was the family room zone. The blower running all night trying to get that zone cool.

Sometimes the compressor turns on fine then later that night at bedtime it won't and it's just the attic blower working.  We turn off the breaker then turn back on after a short 1 min wait and then it starts fine sometimes. Sometimes we just wait a few hours and it comes back by itself. Other tines even when we reset the breaker the condenser won't turn on. Then in the morning it turns back on. They've checked Freon this week and it's fine. As well as a drain valve? was clear.

Is it a bad control board? The zones thermostats not talking?  Or is there a valve or switch somewhere that makes sense why the condenser outside is being so random? Any ideas? It's an

We have an older VanEE DUO 1.9 energy recovery unit in our house which I installed back when I first joined HVAC-Talk in about 2004 or so.  It has been a good unit.  I had to have the motor guts replaced by our HVAC contractor when our house got hit by lightning about 2010 and I have replaced the damper assembly (SV13734) twice in its life.

Upon the house being colder than normal during the last cold snap this winter, I discovered the damper motor is not pulling the damper closed again.  Upon looking for SV 13734, I have found the assembly is discontinued.

Asking our HVAC contractor we have our service plan thru, he is not able to find replacement parts.

In trying to find just the 645F 110V 60Hz 6W 1RPM (or 60RPH) Synchron damper motor part of the assembly, I have been stumped.  It appears the 38586R damper motor with those requirements is not available either.  All I can find seems to be 24V damper motors.

For your customers in my situation:
1. Does anyone know of a source for 110V Synchron motors like the 38586R I need?
2. Has anyone converted the 110V to 24V to use a newer damper motor?
3. Any other advice or help to repair my unit?

Thanks in advance for the help!

QuoteOne fatality and seven injuries resulted from the poisonous gas exposure

Toronto, ON, March 20, 2025 – Brighton-based propane distributor, Gerow Propane Ltd., pleaded guilty yesterday to one count of an offence under the Technical Standards and Safety Act. The offence involved a fatal carbon monoxide exposure at a property in the Township of Hamilton, Ontario. The Ontario Court of Justice ordered Gerow Propane to pay a fine of $80,000, plus a 25 per cent victim surcharge.

Between December 16, 2020, and February 14, 2022, Gerow Propane supplied propane to fuel a boiler installed in the property's garage for heating purposes. On February 14, 2022, a 57-year-old relative of the property owner was found deceased in the garage from carbon monoxide exposure. Additionally, seven other individuals at the scene, including five firefighters and two heating contractors, were injured by the poisonous gas and were hospitalized.

TSSA's investigations revealed that the boiler released carbon monoxide into the indoor space, causing the poisonous exposure. The boiler had been built for use with natural gas but was found operating on propane as its fuel source. Without undergoing the necessary conversion, including the installation of a new orifice suited for propane, the boiler allowed products of combustion to leak.

Despite delivering propane to the property on seven occasions, Gerow Propane failed to comply with Ontario Regulation 211/01 prescribed under the Act, which requires propane suppliers to inspect appliances connected to propane to ensure their safe operation and attach a label confirming compliance with safety codes and requirements.

Owen Kennedy, Director of Fuels at the Technical Standards and Safety Authority (TSSA), said, "This is a tragic event caused by a serious non-compliance. Propane suppliers have a legal responsibility to ensure that fuel-burning devices are installed in compliance with the applicable codes and can be used safely. Any failure to verify this can lead to harmful consequences such as fires, carbon monoxide poisoning, and other hazards."

Mr. Kennedy added, "For consumers, after installing a fuel-burning device in any indoor area, including those separate from your primary living space, it's best to install a carbon monoxide alarm and have the heating equipment regularly inspected by a qualified fuel contractor. These precautions are important safeguards and could have been life-saving in this case."

QuoteToronto, ON, March 19, 2025 – Thomas Cavanagh Construction Limited (Cavanagh Construction) has been fined $100,000 after pleading guilty last week to five safety violations under the Technical Standards and Safety Act. Cavanagh Construction's violations resulted in damage to multiple gas lines in and around Ottawa, causing gas outages for six homes and a retail mall. The Ontario Court of Justice also imposed a 25% victim surcharge.

Between March 28, 2023, and July 24, 2024, while under contract with the City of Ottawa for tunnel and pipeline upgrades, Cavanagh Construction caused 11 gas line breaks. The company had proper locates and maps identifying gas lines and was aware that regulations prohibit using mechanical excavators within one metre of a gas line. Despite this, Cavanagh Construction used mechanical excavators instead of the required hand digging or hydro excavation methods near pipelines, leading to breaks and gas supply disruptions for homes and businesses.

"Using heavy machinery for excavation near pipelines is unsafe, as reflected in our safety regulations, and this case has proven that," said Owen Kennedy, Director of Fuels at the Technical Standards and Safety Authority (TSSA). "It is important to be cautious when digging because unsafe practices can put many people at risk of losing heat, hot water, and the ability to prepare meals. In the most serious cases, it can lead to explosions that cause property damage, injuries, or even loss of life."

TSSA reminds individuals and businesses to contact Ontario One Call before digging to locate underground infrastructure, including gas, hydro, cable, and phone lines. Any damaged pipelines or gas leaks should be reported immediately to the Ministry of the Environment's Spills Action Centre at 1-800-268-6060 or TSSA at 1-877-682-8772.
