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-8C or any controlled equipment.
SELECTING A MOUNTING LOCATION FOR THE DS-8C
The small corded device with the interleaved grid is the remote precipitation or "moisture" sensor.
The brass cylinder protruding from the bottom of the DS-8C enclosure is the temperature sensor.
For reliable rain and snow detection the moisture sensor must be exposed to a clear view of the sky.
Reference Page 7 "Moisture Sensor Mounting & Termination" for guidance in mounting the DS-8C moisture
sensor. For proper temperature detection the DS-8C enclosure must be mounted outdoors, away from furnace
vents, dryer vents, and other sources of heat. Note that, when powered, the DS-8C moisture grid will always
remain hot. This is normal. This allows the sensor to continuously melt/evaporate both rain and snow from
the grid. The DS-8C enclosure can be mounted by screwing the base conduit hub onto an appropriate size
free-standing 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 hazard. It is recommended
that a weatherproof junction box be mounted
below the DS-8C for termination of the power
and load pigtails to the building wiring.
Use Care When Replacing the Front Cover.
Do Not Pinch the Gasket or Overtighten the
Screws.
ALWAYS FOLLOW LOCAL AND NATIONAL ELECTRICAL CODES.

- Page 2 ™ The world’s best-selling electric floor heating brand MOISTURE SENSOR MOUNTING & TERMINATION The DS-8C enclosure and moisture sensor must be mounted outdoors. The remote DS-8C moisture sensor may be mounted in a number of ways depending on the application.
- Page 3 The DEL configuration switch activates the Delay-Off drying cycle timer on the DS- 8C. The timer allows the DS-8C to continue to operate and dry the heated surface through evaporation once precipitation has stopped. The drying cycle reduces the chance of moisture left behind refreezing into ice.
- Page 4 The world’s best-selling electric floor heating brand The DS-8C precipitation sensor is very sensitive and can detect a single snow flake or rain drop. However, if the DS-8C is mounted in an area susceptible to high winds, overhanging trees, or blowing ground snow, nuisance triggering may occur.

- Page 6 POWER & ACTIVATION INDICATOR A green lamp shines through a lens on the cover of the DS-8C to indicate operational status. If this lamp is OFF the DS-8C is not receiving power. If this lamp is steady ON the DS-8C is powered but is not triggered.
