Snow sensor not detecting snow outside?

There can be several reasons for this. First, start by checking the snow sensor supply voltage between pins 2 and 3 of the class two terminal blocks. It should be close to 24 VDC (the label on some unit incorrectly say 24VAC). If there is no voltage...

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

Why do I keep getting the A12 dew point alarm?

The A12 dew point alarm means that the internal humidity sensor is detecting moisture in the canisters. Usually, an alarm may occur for a few seconds and reset itself before it is seen as the unit determines a need to regenerate a canister.

How can I test the snow sensor?

The APS-3C and APS-4C controllers utilize the CIT-1 aerial snow sensor, the GIT-1 gutter snow sensor and the SIT-6E pavement snow sensor to detect weather conditions. All three of the sensors work in the same way, they require a temperature below 38...

The EUR-5A is 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 alone, is not recommended since it will...

Why won’t the sensor turn on the system when it is snowing outside?

There can be several reasons for this. First start by checking the sensor supply voltage between pins 2 and 3 of the class two terminal blocks. It should be close to 24 VDC (the label on some unit incorrectly say 24VAC). If there is no voltage then...

Sensors: ‘Normal’ vs. ‘Extreme’ Environments

Winter maintenance and snow melting systems are designed for “normal” environmental conditions. Sensors and controls for these applications are made the same way. Normally, ETI sensors detect typical...
