Heat-Trace in Hot Water Maintenance

Heat-Trace in Hot Water Maintenance

Heat-trace is used in many aspects of everyday modern life that mostly goes unnoticed. One main example of this is the ability to access hot water quickly from any faucet in a large building no matter how far from the water heater it is. This is a function of a...

Where do I connect the sensor wires to?

The sensor wires are connected to the blue #18 awg wires in the low voltage section. The sensor is not polarized so it does not matter which sensor wire goes to which blue wire. Click here to view the SST-2 manual A representative diagram of a temperature sensor for...

What are the SST-2 striped wires for?

The #18 awg striped wires are to the SST-2 to an external alarm. The SST-2 uses a summary alarm, which will give an alarm for four different reasons: loss of power, failed temp sensor, ground fault test failure and a ground fault alarm. Before connecting the alarm...

Supply light flashing on SST-2

A flashing supply light means that the temperature sensor is either missing or bad. Ensure that the sensor is correctly wired to the two blue wires. The system will not function without a sensor. Click here to see more about the Temperature sensor. Click here to view...

What is the maximum load for the SST-2?

Supply Voltage The SST-2 fixed set point thermostat operates from 120, 208, 240 or 277 VAC at 50/60 Hz. For line supply and load connections, use 10 AWG or larger wires rated for at least 75°C (167°F) at 300 VAC. Contactor Rating The heater contactor provides two (2)...
