Series Description
The Honeywell L480 Series low limit controllers operate electric dampers, valves and compressor or fan motors to provide temperature or limit control of air conditioning systems and refrigeration units. The L480B has an SPDT switch and automatically resets; the L480G has an SPST switch that opens on a fall in temperature and requires manual reset. The L482A has two SPST switches and manual reset; the main switch opens, and the auxiliary switch closes, on a fall in temperature.
