Can the APS activate on temperature only?

[The APS-C series systems are designed to turn on and off, as the weather requires heat to deal with snow or icing conditions. Although a thermostatic dry contact switch can be used to override the system on for temperature only, is not recommended...

Temperature sensor was not installed

The high limit temperature sensor is intended for two purposes, either as a slab sensor when the APS-C series unit is used for heating sidewalks, patios or drives or for ambient air temperature when the unit is used for roof and gutter melt...

Why is my heater light flashing?

A flashing supply light on any APS or EUR-5A control indicates a missing or broken High Temperature Limit sensor. This sensor is required to make the EUR-5A controller to work. The sensor is not polarized and must be connected to pins 1 and 2. Refer...

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.

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.

Where should the temperature sensor be located?

Ideally, the temperature sensor should be located on the pipe on the opposite side from the heater. If this is not possible the sensor can be used as an ambient temperature sensor although it will be less efficient.

For the SST-2 the temperature set point is either 40 °F (4.44 °C) or 175 °F (79.44 °C) depending on the particular model being used. The set point is the temperature the unit uses for switching on and off with a 2 °F deadband. For the 40 °F (4.44...

What conditions will make the sensors call for heat?

The CIT-1, GIT-1 & SIT-6E sensors all call for heat when they sense conditions with both a temperature below 38 °F (3.33 °C) and moisture on their moisture grid. Click here to see more about Snow & Ice sensors

Can I regenerate desiccant and if so how do I do it?

Yes, you can regenerate desiccant start by emptying the desiccant into a clean baking dish. Bake desiccant at 350º for two hours, or until silica gel particles turn dark blue, in a conventional oven (do not use a microwave). After the silica gel...

How to regenerate the desiccant Passive Dehydrators.

Both the RCD-1 and the RCD-2 passive dehydrators are bottles filled with desiccant, the RCD-1 with no moving parts, uses gas diffusion to dry the waveguide while the RCD-2 uses its one moving part (a check valve), temperature changes and barometric...
