Thermostats work nice you can set the dip differential where you want it. You can use it on heating control boxes. Or refrigeration units set your temp and your differential.

Bought to replace the temperature control on an indirect water heater and does exactly what you tell it.Instructions are fine and the basic menu options allow you to set everything most would ever need.Relays may be cheap - not sure how much load I would trust them with - mine controls a separate pump controller so sees not load and will hopefully last.

Was looking around at units with a plug and receptacle, but ended up buying this one without realizing it didn't have one. If you know that you want to hard wire it, then this is the unit for you. Otherwise, it has a 1/2 ko for you to do something with. I used an NM-style cable clamp and hacked a flat molded extension cord. Not exactly UL compliant, but I am satisfied it's safe enough. In the long run I may nipple it into a junction box and mount it to enable/disable a duplex receptacle.Note that while this unit can do heating or cooling, you have to pick one or the other.Note that while the unit looks like it can accept 240V control power, it only appears to have a single relay, so it's not proper for switching two hot legs (and I strongly recommend against it). Perhaps this is useful for countries with 220V or 230V to ground single phase.It lets you set the on and off setpoints individually, which is nice. It also has a setting for a restart delay, which can be set from 1 to 12 minutes. (Delay protects your compressor equipment from hot starts.)

I've been using these for 8 years in an application where they switch constantly day and night. Combined with RIB relays to isolate the loads from the controllers, these have been flawless. These do exactly what they should do year after year. These harken back to a time when things were built to last and do the job they are supposed to do. It's a shame so many products fail to produce the bare minimum. I have 4 of these (actually the other 3 are pre Penn and one is pre 421 designation) running in various tasks in my house and will always go to Johnson Control (now Penn) for this application assuming they continue to build a quality product.

This says it works for heat but I set the on at 100 deg and off at 130 will not shut off after it drops below on set temp it will keep running.

This was a gift and I do know it is being used. So it must work.

The instructions provided are not very clear on setting up the controller, but once you get it figured out it works great. I used this to turn a stand up freezer into a refrigerator for my backyard shop. It holds at a steady 38 degrees in a non-insulated metal building. Youtube is your friend when trying to set it up.
