Description
The AMC-1A thermostat is designed for controlling freeze
protection heat-tracing systems in nonhazadous locations. The
thermostat responds to ambient temperature changes. The
AMC-1A can be used to control a heat-tracing circuit directly (see
Figure 1 on back page) or it can be used to control a contactor coil
(see Figure 2).
