DEScRIpTION
The DigiTrace AMC-2B-2 thermostat is designed for controlling
heat-tracing systems in nonhazardous locations. The thermostat
functions as a DPST switch.
The DPST switch will enable and disable current flow in both
buses of the heat- tracing cable.
The AMC-2B-2 can be used to control heat- tracing circuits in a
pipe-sensing mode directly (see Figure 1 on back).
Note: Do not use this thermostat to control two separate heat-
tracing circuits.
