## 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.

Review: Works great - was able to extend the reach of my sensor by myself - The control unit I bought came with a 2' sensor lead on it - found this one and was able to change it out (2 wires) and extended my reach quite a bit. Worked perfectly for setting up my outdoor wood boiler after a fire burnt up my old control unit - I was able to mount this controller off the unit in a protected area so if there ever is a flame up the control box will be safe.
