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-2C or any controlled equipment.
SELECTING A MOUNTING LOCATION FOR THE DS-2C
The interleaved grid on the top of the DS-2C is the precipitation or "moisture" sensor. The brass cylinder
protruding from the bottom of the enclosure is the temperature sensor. For reliable rain and snow detection
the unit must be mounted in a location that exposes the moisture sensor to a clear view of the sky.
The unit should not be mounted directly under eaves or overhangs. It should not be mounted so close to the
ground that it may become buried in snow. For proper temperature detection the DS-2C must be mounted
outdoors, away from furnace vents, dryer vents, and other sources of heat. Note that, when powered, the
DS-2C 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.
The DS-2C 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-2C 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.

Summary of Contents for Warmup DS-2C
- Page 1 SELECTING A MOUNTING LOCATION FOR THE DS-2C The interleaved grid on the top of the DS-2C is the precipitation or “moisture” sensor. The brass cylinder protruding from the bottom of the enclosure is the temperature sensor. For reliable rain and snow detection the unit must be mounted in a location that exposes the moisture sensor to a clear view of the sky.
- Page 2 The DS-2C precipitation sensor is very sensitive and can detect a single snow flake or rain drop. However, if the DS-2C is mounted in an area susceptible to high winds, overhanging trees, or blowing ground snow, nuisance triggering may occur.
- Page 3 “Manual On” position. However, any trigger of the system will restart the 40 hour “Manual On” timer. You may put the DS-2C back into “Manual On” mode by switching to AUTOMATIC, then back to MANUAL ON. This will also restart the 40 hour timer.
- Page 4 The Yellow load leads are N.O. contacts and do not supply power directly to your load. The relay inside the DS-2C acts as a switch. While not as convenient as directly supplying power for the load this allows you to operate the DS-2C from one voltage while controlling a load of a different voltage without adding an external relay or contactor.
- Page 5 POWER & ACTIVATION INDICATOR A green lamp shines through a lens on the cover of the DS-2C to indicate operational status. If this lamp is OFF the DS-2C is not receiving power. If this lamp is steady ON the DS-2C is powered but not triggered. If this lamp is FLASHING the DS-2C is powered on and triggered, the main relay is closed, and attached equipment should be activated.
