Description
The A421 Series Electronic Temperature Controls are single-stage controls with a single-pole, double-throw (SPDT) output relay. A421 Controls feature a bright backlit LCD with adjustable brightness and a three-button touchpad interface that can be set up to restrict user adjustments. An LED indicates the output relay's On/Off status. Standard A421 Series control modules have simple On and Off temperature settings for heating or cooling, an adjustable anti-short cycle delay, temperature setback, and sensor offset capability. The temperature control range is -40 to 212°F or -40 to 100°C. The A421 controls are available either in Type 1 (NEMA), IP20 (CE), high-impact plastic enclosures suitable for surface or DIN rail mounting or in Type 4X (NEMA), IP67 (CE) watertight, corrosion resistant surface mount enclosures.

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.)
