Time Delay Relay used in industrial automation system and mechanical equipment to delay component. Relay is a kind of automatil electric switch, when supply with an input value, like electric, magnetic, light or thermal signal, it wall transfer the controlled circuit automatically and make an abrupt change, when the input value decreased to certain degtee, it will resume to former state and make the controlled circuit back to the former stare.

The TCS-1 features an auxiliary voltage supply of 24,48V AC/DC with 13-30V AC/DC of the circuit under control. This unit has eight to nine terminals, and a tripping time delay of 0.4 to one second. The reset time of the TCS-1 is 0.6 to one second and the working temperature range for this unit is -10 to 60°C. This is a highly efficient and reliable unit with a long lifespan, with a two changeover output and 5A 250V contacts. Other Contrel elettronica products I've been experimenting with my family lately. Or is it, experimenting on my family?

In either case, I've got the data to confirm something I wrote in a 2011 article. But before I tell you what I did, first let me show you what happened. Here is Exhibit A: A Moisture Mystery. What do you think happened to cause the humidity (blue data) in the air in our condo to rise like that? Why did the humidity spike? The graph above shows the temperature and dew point, measured with a data logger on the main return grille in the living room, from early August to early September. The indoor temperature in our condo stayed mostly around 75° F, with a few excursions when we adjusted the thermostat. But the humidity showed something really interesting. Starting on 18 August and ending on the 23rd, the dew point took a significant jump upwards. It had been averaging about 60° F then shot up to about 65° F for a few days before coming down. Here are a few hypotheses: I finally started showering and then got freaked out and stopped. I showered without using the bath fan.

I brought in a lot of outdoor air for ventilation. Well, it was none of the above. The answer is given in the two graphs below. This thermostat setting is to blame At about 8 am on 18 August, I changed the thermostat fan setting from "auto" to "on" and ran it that way for the next five days. As you can see in the graph above, the relative humidity (RH) also spiked and averaged 70% during the time the fan was running continuously. Why did the RH and dew point go up? While the air conditioning cycle was running, the indoor coil got cold. Water vapor from the air passing over it would condense on the coil. When the compressor turned off, the coil would warm up. The water remaining on the coil normally would just sit there until the next cycle, with some of it evaporating and sitting in the air inside the coil housing. But with the fan running continuously, the air passing over the coil as it warmed up would evaporate that water and put it right back into the house.

Keeping the relative humidity at 70% is not a good thing. That's about the threshold where mold can really take off. If we left our thermostat set to the fan-on position all summer, I'm sure we'd have a mold factory in our condo. So if you've been told to run the fan continuously by someone who sold you an electrostatic filter, UV lights, or some other indoor air quality device, you may not have been given the complete story on how such products affect the IAQ in your home. The higher relative humidity also meant that our home was less comfortable. We average about 58-59% with the fan set to auto, and even that's not ideal. The main reason for that is the short runtimes of our air conditioner, which I wrote about last week. The graph above shows the dew point data by themselves with the mean values before, during, and after the fan-on period. One thing that surprised me was how quickly the humidity rose when I changed the thermostat. Within minutes, I noticed the RH reading moving up.
