Reasonable price and shipping time. Goo product, secure packaging

Was a replacement for an old one

I have a two stage evaporative cooler that is controlled by very old non smart control board and thermostat combination. It however works well. But, I wanted to connect my evaporative cooler to 3rd gen nest learning thermostat for obvious benefits. After doing lot of online research, this control board seemed to be the one that fits my needs. The control board provided RWYG outputs. However, I connected them in the following fashion: W -> Y1 Y -> y2 R -> Rc G -> G It did not work in that configuration. After doing some more research, I concluded that the power supplied by R is not sufficient and also Needed to add a C wire. I went to my local hardware store and got a doorbell transformer that can output 24v AC. I connected one wire from the transformer to the R on the white rodgers board and connected the second wire from the transformer to another free wire on my low voltage wire that is going back to thermostat through attic and walls. I connected the new strand from the low voltage wire to the C on the thermostat. It worked perfectly at this point. And I am able to control both stages of cooling and FAN properly using the thermostat. I read online in ome forums that the white rodgers control board itself has 24v ac output (i think at lower end of CR2 (is it a resistor ?). But, did not try it out. I will check this when I get up on the roof next time :-) If that works, I can avoid the 24v AC transformer.

Works great

I have never had a complaint from a customer, and now that the motor relay has been improved (it was weak) I am even more pleased. Many people here in AZ prefer to use a swamp cooler in the moderate months of the year not only for cost reasons, but for overall comfort, and this product fills the bill. With a delay for the blower, and a reliable t-stat the cooler becomes just as convenient as a refrigeration unit. Reasonable cost, easy install, and instant shipping from Supply House. All good.
