No, the SC-40C does not use a snow sensor, it is completely controlled by the attached APS-4C. However, the SC-40C does require the High-Temperature sensor Thermistor to be connected (or bypassed with a 470K-ohm resistor) in order for the unit to...

Can I simulate a sensor call for heat?

Yes, you can simulate a sensor call for heat to test the system by putting a jumper between pins 1 and 2 of the class two terminal blocks, the system will respond as if the sensor were seeing snow conditions. The snow and heat indicators will come...

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...

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...
