Im a bit confused the previous threat of wiring it to the w-c would be correct to have it open for heating. It sounds like you are talking about combustion air and dampers if this is the case this...

To swap a Hy Vent and change it on the fly expect some leakage. I would protect the space if it is finished but this is a major time saver.

Just a note the system I am referring to has a dry return. It is important to know if you have a dry return or liquid.
One other point and something I am dealing with now at a location. The air vents at some time were capped off and in order to heat the building the pressure was increased from 1.5 lbs to now nearly...
With Pneumatic there is little you can do but to trace out the lines to find the failure with a BAS system with the appropriate points you can find the location through point failures or duct...
The supply lines may have low points where condensate collected many steam systems are not the same as the original design and changes cause low points that are only noticeable when the system...
Muti stack is a great product just worked on a hospital install and the modular concept makes sense in this environment. Hospitals are always expanding so a expandable chiller makes sense. One note...
If you think this is due to the install of the power vent take a look at the draft proving switch often these are clogged. In any event if the draft does not prove the burner is wired into the safty...

Ok now I see what you are thinking. (Heat Recovery) there are many companies offering refrigeration energy retrofits utilizing the waste condensor heat in a heat recovery strategy. In essence...
Sounds like the air cooled chillers with chiller barrels. Utilize water source loop then heat exchangers to transfer to the refrigerant side. But not both at once which would work but with todays...
There are a whole bunch of issues if this were to be installed in our location within code. Is this a Modine or some other manufacturer. Modines make some direct vent models and some power vent...
There are three universal IO's and a software tool to setup for occupancy detection. The logic is built in so you may want to check standby versus total fan shutdown if you have a reason to shut the...
Sometimes it takes a few starts to draw a vaccume and start the flow from the bleed port. You can jump out the eye and let it run with the bleed port open without it going out on saftey. If still...
Im with the two stage furnace two stage Tstat. That being said if there are wiring constraints and for some cost issues single stage and set to delay would work. I am in a severe climate so a delay...
On commercial units Carrier can give you details on the exact defrost boards installed in the units. You would need the Serial Number and Model Number just as you would to source the board.
There is no way to reset steam as there is with water in a Hydronic System. In a one pipe system you would want to be certain the thermostatic air vents are working correctly at the radiators and...
