- Page 2 DELAY ADJUST Setting the Adjustments The DS-8 is specifically designed for snow and freezing rain detection only. This section explains the functions of the adjustments. Trigger temperature is adjustable from 34°F (1.1°C) - 44°F (6.6°C) using the temperature adjust (TEMP) control. When ambient air temperature is below this trigger point precipitation is assumed to be snow or freezing rain.
- Page 3 The DS-8 can be mounted by screwing the conduit hub onto an appropriate size conduit or by using the mounting holes in each corner of the enclosure. DO NOT DRILL HOLES THROUGH THE ENCLOSURE FOR MOUNTING! This can allow water into the enclosure causing a potential shock or fire hazard.
- Page 4 240VAC for heating wire. The following diagrams show some possible wiring schemes for connecting the DS-8 to your load. Your load may be a direct connection to a heater, a contactor, or a control voltage. For clarity the safety GROUND leads are not shown.
- Page 5 240VAC In, Thermostat-Style for Boiler/Pump Control (Strap DS-8 for 240VAC Power) These are just some of the possible wiring schemes that can be used to connect the DS-8 to your load for control. The DS-8 should always be strapped for the voltage that is connected to Line/L1 and Neu/L2.
- Page 6 Power & Activation Indicator A yellow lamp is mounted on the base of the DS-8 to indicate operational status. If this lamp is OFF the DS-8 is not receiving power. If this lamp is steady ON the DS-8 is powered but not triggered. If this lamp is FLASHING the DS-8 is both powered on and has activated the deicing system.
- Page 7 Preseason Testing It is always a good idea to test the operation of the DS-8 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 moisture grid following the procedure...
