General Safety Instructions
1. THIS UNIT SHOULD BE INSTALLED, OPENED, AND REPAIRED BY QUALIFIED
PERSONNEL ONLY!
2. To avoid shock hazard do not open the front cover with power connected to the DS-824 or any controlled equipment.
3. Limit input voltage to 22-28 VAC/VDC.
4. Replace fuse F1 with a 2 Amp 32 V or 250 V 3AG fast acting fuse ONLY.
Moisture Sensor Mounting & Termination
The remote DS-824 precipitation/moisture sensor may be mounted in a number of ways depending on the application. The
DRIP EDGE
SENSOR
unit operates at a safe 24 VAC/VDC and can withstand immersion in water. For roof and gutter deicing applications the sensor head may be mounted in the gutter against the fascia board with a 1” “C”-style conduit clamp. Allow part of the sensor grid to be exposed to snowfall. This allows the sensor to initially trigger when snow starts falling and remain triggered as long as
GUTTER
the roof/gutter heater continues to drip melted snow from the roof edge when temperatures are below freezing. The sensor may also be installed inside and near the top of the downspout using a 1” conduit hanger and mounting plate. As water is melted in the gutter it will run to the
DOWNSPOUT
downspout, hitting and retriggering the sensor. We do not recommend laying the sensor in the gutter. Constant immersion will corrode the grid and the sensor may miss a windblown snow trigger.
The sensor cable comes preinstalled but may be shortened as needed. Strip the outer insulation and shield from the cable and terminate each conductor following the color code printed on

CLAMP
the circuit board. The bare drain wire should be installed into the terminal marked “Shield”. Wrap a cable tie securely around the cable in the enclosure to provide additional strain relief between the flexible enclosure gland and the free end of the cable. Please call for guidance if additional length is required. Erratic operation may result if the proper cable is not used.
Selecting a Mounting Location for the DS-824 Enclosure
The rubber “boot” protruding from the bottom of the DS-824 enclosure is the temperature sensor. For proper temperature detection the DS-824 must be mounted outdoors, away from furnace vents, dryer vents, and other sources of heat. Note that, when powered, the DS-824 precipitation grid will always remain hot normal. This allows the grid to continuously melt snow and evaporate both rain and snow from the grid.

Power & Activation Indicator
A yellow lamp is mounted on the base of the DS-824 to indicate operational status . If this lamp is OFF the DS-824 is not receiving power. If this lamp is steady ON the DS-824 is powered but not triggered. If this lamp is FLASHING the DS-824 is both powered on and has activated the deicing system. Note that, even though snow may have stopped, the DS-824 indicator may be flashing indicating the system is on. The indicator will continue to flash during the Delay-Off drying cycle.
Preseason Snow Detection Testing
It is always a good idea to test the operation of the DS-824 prior to the winter season. Procure some clean water and, if the outdoor temperature is above the trigger point, a can of spray component cooler (Radio Shack Part #64-4321 or equivalent.) Clean the precipitation grid following the procedure outlined above and allow it to dry. Apply power to the DS-824 and drip some of the water onto the precipitation grid, and then spray the temperature sensor protruding from the base of the enclosure with the component cooler. Once the temperature sensor has reached the trigger point with water still present on the grid the DS-824 will activate. The user should hear the internal control relay close. Proper operation has been confirmed. Allow the grid to dry completely. To clear the Delay-Off timer place the override switch into “Standby/Reset” , and then back to the “Automatic” position.
