Yea, i been using a419 for a long time - They served me well for many years. , now these A421's replace them and seem good so far. i have not used the defrost included ones yet , but A421 good so far. This place allready had a defrost clock so this a421 works good so far.
Yea, its definately my go to also. But i do carry other stuff on the truck these days. youkind of have to. carels, danfoss, dixells , inkbirds for change outs on all these new type of units.
On the digital temp. controller find the set of contacts . ie: on a Johnson a421 controller it will say “c” for common & “ N/o “ for Normally open. your 2 wires go there since all that control does is open & close a set of contacts like a light switch. You will just need to run 2 power wires to supply operating voltage to your control. & whala ! your done.
Yes , they are available with or without defrost. this one inthe video is without defrost. i believe they look exactly the same. defrost or no defrost. its just a programming thing.
I like the A421ABD-02C with defrost built in. Great stats.
