Application: electric heat tracing control
The R1 and R3, equipped with double-pole switches, are designed for use as adjustable control thermostats for freeze
protection and temperature maintenance applications requiring pipewall or tankwall sensing.
The R1 thermostat is approved for indoor/protected use in ordinary (non-classified) locations. The R3 is approved for
indoor/outdoor use in ordinary (non-classified) locations.
