REFRIGERATION & AIR CONDITIONING Commercial Temperature Controls

Electronic Remote Temperature Controllers • Provides on/off, modulating or reset control in applications where electronic accuracy and remote sensing is desired

is a stage sequencing model that allows configuration of up to 12 relay outputs with one or two setpoints using L43-814 relay expansion modules • L43-813 is a universal model that uses 0 to 10VDC or 4 to 20mA sensor input to control pressure, humidity, temperature

• Available with analog outputs (0-10VDC, 2 to 10VDC, 4 to 20mA or Series 90 selectable) • Internal time clock scheduler allows for energy savings during unoccupied periods without the need for a separate time clock L43-812
