- Page 2 For proper temperature detection the DS-224C must be mounted outdoors, away from furnace vents, dryer vents, and other sources of heat. Note that, when powered, the DS-224C moisture grid will always remain hot. This is normal. This allows the sensor to continuously melt snow and evaporate both rain and snow from the grid.
- Page 3 The DS-224C precipitation sensor is very sensitive and can detect a single snow flake or rain drop. However, if the DS-224C is mounted in an area susceptible to high winds, overhanging trees, or blowing ground snow, nuisance triggering may occur.
- Page 4 “Manual On” position. However, any trigger of the system will restart the 40 hour “Manual On” timer. You may put the DS-224C back into “Manual On” mode by switching to AUTOMATIC, then back to MANUAL ON. This will also restart the 40 hour timer.
- Page 5 The Yellow load leads are N.O. contacts and do not supply power directly to your load The relay inside the DS-224C acts as a switch. While not as convenient as directly supplying power for the load this allows you to operate the DS-224C from one voltage while controlling a load of a different voltage without adding an external relay or contactor.
- Page 6 24 VAC/VDC Sensor Supply, Secondary Voltage Out These are just some of the possible wiring schemes that can be used to connect the DS-224C to your load for control. Remember, these are only suggestions. You should always consult a qualified...
- Page 7 (Radio Shack Part #64-4321 or equivalent.) Clean the moisture grid following the procedure outlined above and allow it to dry. Apply power to the DS-224C, drip some of the water onto the moisture grid, 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-224C will activate.
- Page 8 Within the limitations of this warranty, inoperative units should be returned, freight prepaid, to ASE, and we will repair or replace, at our option, at no charge to you with return freight paid by ASE. It is agreed that such repair or replacement is the exclusive remedy available from ASE and that ASE IS NOT RESPONSIBLE FOR DAMAGES OF ANY KIND, INCLUDING INCIDENTAL AND CONSEQUENTIAL DAMAGE.
