Question about Fantech EDF5 Intellitek 5MR Control for HRV/ERV's White

2 Answers

Is EDF5 required to have intermitant running of Fantech HR 2005R?

Installed SHR 2005R on new HVAC system (indoor exhaust from hallway return air and with fresh air into house thru return air trunk before it turns down to filter and air handler). Wired per Alternate Accessory Control Contact as in manual (to exterior COM, N.O. & N.C. contacts). If I set to low or medium with rocker switch, furnace fan runs continuous along with HRV fans. If I set rocker switch to stand by it does not cycle on when furnace comes on and blower is running. Is there a way to wire the HRV to operate any time the air handler is running (heat or air) but not operate continuous as it does now when rocker is set to low or medium (which also runs air handler all the time??

In my case I didn't have to get additional controllers to make it work intermittently.

I wired it to my Honeywell VisionPRO IAQ thermostat interface, which has 2 dry contacts for ventilator. They should be wired to the "dehum" contacts on the Fantech system.

Then you'll have to control it via the thermostat on timed operation or leave it on "Auto" and will automatically circulate based on your settings. I hope this helps.

The SHR2005R will turn on the furnace Blower if the furnace is not running to circulate the fresh air. The reason the furnace will not trun on the HRV is, the purpose of the HRV is continuous Ventilation in your home. It should not be turned off when your furnace is not running. That why Fantech has not design the HRV's to run that way. I hope this helps.

SOURCE: Fantech FD60EM electronic timer control makes a loud buzzing sound and does not operate the fan

This timer appears to be Leviton LTB60

Timer has 1 year limited warranty, evidently from manufacturer.
If timer is making humming sound, then it is defective, possibly receiving undervoltage on the line, or wiring installed incorrectly.

Switch noisy timer with one of the other timers, and see if problem follows the timer, or is related to the specific location.
Otherwise replace with LTB60 from Amazon for $24.
Or buy Intermatic Ei200 timer, or replace non-electronic with spring-wound timer such as 60-minute Intermatic FD60, or 30-minute FD30, etc.

Is there a way to test indoor air quality in my home ?

Yes. There are few many indoor air quality testing & building performance firms that do air quality testing. Some specialize just in this discipline.But keep in mind that even the best HVAC system needs fresh air from outside. Also i've heard a thing called a sling psychrometer. it measures moisture content in the air. you want 50% humidity. all HVAC companies have them.

What is hvac

Hi, Hvac that i know is (Heating, Ventilating, and Air Conditioning) refers to technology of indoor or automotive environmental comfort. HVAC system design is a major subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).

HVAC is important in the design of medium to large industrial and office buildings such as skyscrapers and in marine environments such as aquariums, where safe and healthy building conditions are regulated with temperature and humidity, as well as "fresh air" from outdoors.

Heating, ventilating, and air conditioning is based on inventions and discoveries made by Nikolay Lvov, Michael Faraday, Willis Carrier, Reuben Trane, James Joule, William Rankine, Sadi Carnot, and many others.

The invention of the components of HVAC systems went hand-in-hand with the industrial revolution, and new methods of modernization, higher efficiency, and system control are constantly introduced by companies and inventors all over the world. The three central functions of heating, ventilating, and air-conditioning are interrelated, providing thermal comfort, acceptable indoor air quality, within reasonable installation, operation, and maintenance costs. HVAC systems can provide ventilation, reduce air infiltration, and maintain pressure relationships between spaces. How air is delivered to, and removed from spaces is known as room air distribution.[1]

In modern buildings the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings, contractors normally "size" and select HVAC systems and equipment. For larger buildings, building services designers and engineers, such as mechanical, architectural, or building services engineers analyze, design, and specify the HVAC systems, and specialty mechanical contractors build and commission them. Building permits and code-compliance inspections of the installations are normally required for all sizes of buildings.[citation needed]

The HVAC industry is a worldwide enterprise, with career opportunities including operation and maintenance, system design and construction, equipment manufacturing and sales, and in education and research. The HVAC industry had been historically regulated by the manufacturers of HVAC equipment, but Regulating and Standards organizations such as HARDI, ASHRAE, SMACNA, ACCA, Uniform Mechanical Code, International Mechanical Code, and AMCA have been established to support the industry and encourage high standards and achievement.

Hope is the one your talking about.

We have a Maytag Electric dryer that is not heating up totally. Removed the vent tube and seemed to help but I check the Ohm's on the thermometer and was working. Tsted the col for ohms and at the RX1...

Hi, If your resistance is 2-3 Ohms, then your element is on it's way out . It needs to be replaced. The resistance should be in the range of 7-20 Ohms on a 240 Volt dryer heating element with the multimeter set at RX1. Good work finding that.

There are some additional reasons a dryer will not dry, have no heat, or cause the element to burn out prematurely.

1 If the exhaust vent run distance is too long. i.e. more that 15 feet the heating element life will be shortened Why? Because in a long vent run the vapor from the most clothes condenses on the sides of the vent hose and lint sticks to it. This lint accumulates and reduces the internal diameter of the hose. This increases air friction and the element runs at a higher temperature, etc. etc.
Solution: Clean the vent system out, or replace with a shorter system, if possible. There is an accessory fan available that can be installed that allow you to have a very long exhaust vent run. See Link

2 Exhaust vent hose folded or squeezed almost or completely shut at back of dryer. This ocures when the machine is too close to the wall pinching the hose. No air carrying the moisture leave the dryer.
It can get hot and after the cycle is done. The clothes are still wet. Solution: Pull out dryer and unfold hose.

Don't use a dryer without a vent hose attached. The dryer will pull the hot air with lint in it back into the machine. Over a period of time this lint can accumulate in the machine and cause a "lint fire" Lint fires inside a dryer sometimes turn into house fires.

Hope this helps,
Happy New Year

Unbalanced cooling or heating

You need to balance the system. It's a matter of adjusting the dampers or registers so that you have a little less air flow near the T-stat and more to the other end of the house. Likely you have a return vent near the T-stat. That return draws air to it and likewise the T-stat. If you are getting a lot of air out of the registers on that end of the house damper them to force more air to the other end of the house. Do not close them entirely though. You may have to play with it a little to get it right. I hope this helps. Please remember to rate Fixya rate me.

My air condition has a water in the pan and not cooling the air

You are most likely low on freon. This would cause the system to not cool. It will also cause the indoor coil to freeze up with ice, then when the ice melts, it doesn't run down the designated path and drips outside of the unit. This will require an HVAC tech to fix.
