## Description

Post-purge fan delay timer with adjustable 12-390-second time delay.

Review: The Savings are Rollin' in Now as a HVAC fan delay! - This arrived early in my mailbox. It was easy to install (for an old HVAC guy), and delays the indoor blower from shutting off right when the thermostat is satisfied. It's all low voltage control wiring. I am now playing with the timing to see what the optimum setting is for squeezing out the most efficiency (i.e., fan running right amount of time past thermostat shut-off). Easy to mount on the wall with a drywall screw - easily accessible so I can easily adjust the time setting. Have wanted to do this since we moved in here a year ago! I will say the diagram on the unit, which shows internal function, didn't make much sense. The switch shown in the diagram as going to terminal 4 makes better sense to me if it was showing to terminal 1, which is the load terminal (goes to fan relay). Just use the diagram on the paper that comes with it. (transformer wired across terminals 2 & 3 - be sure to match polatrity, thermostat to 4 and load on 1)
Review: Delay Relay Works Great But Some Caveats - As others have said, the schematic printed on the relay is wrong! The accompanying piece of paper is correct. Pins 2 & 3 require a constant 24VAC. With pin 2 being the red wire and pin 3 the black (common). You connect the green (fan) wire from the thermostat to pin 4. Connect pin 1 to your fan relay. When the relay receives a signal from the thermostat on pin 4, it connects pins 1 & 2 together. The relay says it will do a delay of 12-390 seconds. This is wrong. The shortest delay (the dial pointing at 12) is 2 minutes and 56 seconds. I have left it connected with the 3-minute delay. It seems to be working okay.

## Features

- UL 873 recognition for compressor applications

## Questions & Answers

**Q: Does it turns on immediately and stays on until break plus the delay time requested?**
A: Hello.This relay has a post purge manually adjustable delay from 12 to 390 second.Let us know if you have any other questions.Customer Support Team of PartzStop.

**Q: If trigger power is restored during the delay, will it still cut off when the delay time is reached?**
A: The question is a bit ambiguous with out a wiring diagram.  The normal application is to extend the on signal.  This is a control relay, it does not power the fan directly.  The unit extends power on "control" by up to 5 minutes.  If the trigger is off due to power outage the relay is off too. The timer starts over when power on is restored and the trigger is high.

**Q: would this work on dc?**
A: I am not sure if it work with DC. There could be internal circuits that could get damaged with direct current.
You may want to submit your question in their website. I believe it is www dot icmcontrols dot com

**Q: From the 12 second setting how many seconds are added with each adjustment**
A: Considering the graduation, does not look like it is linear! If I have to guess, it maybe 40 seconds each marking after the 12. After number 12, there are four more divisions then number 200 then again another four and last number is 390. Go figure!!

### ⭐⭐⭐⭐⭐ Perfect for Central A/C In Dry Climates
*by B***Y on November 23, 2013*

My furnace has a built-in delay that keeps the fan running for 60 seconds after the call for cooling ends (as do some electronic thermostats), but I knew there was still a lot of cooling remaining in the evaporator coil if I could only run the fan a little longer. So I installed this little gem on my furnace and set it for its stated maximum of 390 seconds. (The actual delay it delivers is closer to 410 seconds, but I’m not going to quibble.) This relay does exactly what I expected it to do, and at a very attractive price point. The main benefits to me in the dry Colorado climate are: - increases humidity in the house during the cooling season (since much of the humidity remaining on the coil at the end of the cycle is returned to the house instead of going down the drain) - dries the evaporator coil after each cooling cycle making it less likely to get moldy or grow bacteria - improves efficiency of the A/C by extracting more cooling from the electricity used. Wiring was pretty straightforward (but I’m an engineer). The device is installed in series between the G (fan) wire coming from your thermostat and the G terminal on your furnace, but also needs Common and Hot 24 volt connections from the furnace. It also requires the use of “disconnect F” quarter-inch tab connectors and a crimper. Unless you are already skilled with low-voltage furnace wiring or really good at reading wiring diagrams, to avoid damaging your furnace or yourself, I recommend you get a pro (or a skilled friend) to help with the install.
