First and foremost, these units are designed to be mounted outside. For reliable snow and rain detection, the moisture grid must be mounted in a location that exposes it to a clear view of the sky. Therefore, do not mount underneath eaves or overhangs. Do not mount unit near furnace vents, dryer vents or other sources of heat since this would negatively impact its ability to accurately register outside temperature (temperature sensor). If not mounting the unit on or against the house, avoid placing it in a high traffic area where people will trip over it.The units can be mounted using a free standing, appropriately sized conduit or by using the mounting holes on each end of the units. DO NOT DRILL HOLES THROUGH THE ENCLOSURE FOR MOUNTING! This can allow water into the enclosure causing a potential shock or fire hazard. It is recommended that a weatherproof condulet or junction box be mounted beneath the DS5 for termination of the power and load pigtails to the building wiring.
2.2 Wiring the DS2
There are 2 yellow wires, 1 green, 1 white, 1 black
Your unit will come configured with the following settings: "Configuration switch Snow/On": This means that the moisture grid is set up to power on the heating system when snow is detected. "Rain/Off": This means that the moisture grid will not power on the heating system when rain is detected. "Delay/On": This means that the heating system will stay on after precipitation has no longer been detected. This will serve to prevent any refreezing of melted snow or ice. "LTC/Off": This feature is designed for limited output systems. When turned on, the controller will not power on the heating system when precipitation is initially detected and the outside temperature is below 15 degrees. The unit assumes that light, puffy snow is falling that would not be an issue. Since we do not produce limited output systems and are designed to keep snow from piling up (light or otherwise), you will typically keep this setting as is. "Temp Adjust" determines at what temperature the unit will power on the heating system. It comes set at 39 degrees. When moisture is detected below this trigger point it will assume snow is falling. When above this trigger point it will assume rain is falling. In either instance, if Snow, Rain or both are selected on the configuration switch, the heating system will power off once precipitation has ceased and the delay time has completed its cycle. "Delay Adjust" determines how long unit will keep the heating system on after precipitation has stopped. It comes set at 30 min at the 12 o’clock position and a maximum of 90 min at the 4 o’clock position. Control Switch (On front cover) Should be in the “Automatic position.” When making any changes to the aforementioned settings, you will put the switch in "Standby/Reset" position and then back to the automatic position. The "Manual On" position will be used for testing purposes and should not be left on.
4.1 Why does my sensor trigger without precipitation?
The precipitation sensor on a DS unit clears itself by evaporating the rain for snow that lands on it. Over time, minerals and contaminates con be left behind by the evaporation process, thus making the sensor think that it still needs to be active. This can also be caused by testing the sensor using a liquid other than clear water. Soda or saliva are not good substitutes! It is recommended that the sensor grid be cleaned with water and a non-metallic (Scoth-Brite TM or equivalent) cleaning pad about every 4 months.
4.2 My sensor is triggered but no voltage is coming out of the load leads.
You have correctly wired the DS2 to your power source as evidenced by the fact that the sensor powers on but your mat has not been correctly wired to the DS.Check to make sure that the black wire from the mat’s power lead is connected to the remaining yellow wire of the DS (the other yellow wire of the DS is going to the power source). SEE INSTALLATION INSTRUCTIONS FOR DETAILS. REMOVE ALL SENSOR AND CONTROLLED POWER BEFORE OPENING THE FRONT COVER!!!! Always check with a licensed electrician and observe local codes.
4.3 Why does my DS unit not operate the way I expect it to?
The sensors contain configuration switches that allow the sensor to operate properly for the application. This is what gives you flexibility. Your unit is preconfigured for the most common applications. Check your settings as described below – you can refer to diagrams on pg.30.Configuration Switch: Snow on - detects snow, Rain on – detects rain,Del (delay) –determines how long heat will be provided after precipitation has stopped to prevent water from refreezing into ice.LTC (low temperature cut off) – Used for systems with limited power output. It keeps the sensor from turning on if initial precipitation is detected below 15 degrees F. At this point you would likely be dealing with fresh snow or rain that has not melted and created ice. However,if the sensor has already been activated, it will ignore the low temperature cut off setting and perform as usual. This setting would be turned off for Warmup’s snow melting systems since they are designed with the ability to melt snow and ice regardless of the outside temperature, thus ensuring that your walkways, stairs and driveways will remain snow/ice free right from the start without any delay. Temp Adjust: When the ambient temperature is below the number selected the sensor will assume that the precipitation is snow. When the SNOW switch is in the “on” position it will power on the snow melting system until precipitation has ceased. When the temperature is above this temperature it is assumed that it is rain. If the RAIN switch is in the “on” position it will power on the snow melting system until precipitation has ceased. Delay Adjust: The timer will determine how long the heating system will remain on after precipitation has stopped to provide a drying cycle to prevent refreezing of moisture. Controller will reset once precipitation begins again. Minimum time of 2min and max of 30. Comes set at 30min. Only use "Manual On" for testing purposes. Never leave “Manual On” on this setting.
4.4 My sensor just sits there. What could be wrong?
There could be a number of issues. Here are a couple of tests to perform: 1. Remove any connected remote control and monitor cabling. Confirm that the distant end leads of these cables are properly terminated and are not touching any metal surfaces or other leads. 2. If the precipitation grip is getting hot this means power is making it to the unit. If not, check the onboard fuse and the input power wiring (the fuse is directly above the grid jack and can be replaced. 3. Is the unit strapped for the correct input power? Running 240VAC into a unit strapped for 120VAC will normally blow the fuse and call the precipitation grid to be cool. The fuse can easily be replaced if this happens. At the same time, running 120VAC into a unit strapped for 240VAC will warm the grid but not allow the unit to operate. 4. Try turning the Delay adjustment down to the 9 o’clock position. This is a forced Manual On position. The load contactor should close. Return the Delay adjustment to is original position (whatever it was previously set at). The load contactor should open and the unit should function properly.
4.5 My sensor triggers properly most of the time but seems to miss very wet snow.
Wet snow tends to fall at elevated temperatures. While it could be above freezing outside the colder upper atmosphere may allow snow to form. This occurs regularly in high altitude locations. This why the center position for the Trigger Temperature is 39 degrees rather than 32 degrees.You can try adjusting the Trigger Temperature higher to activate the system when such conditions are prevalent. Also, make sure that the sensor is not mounted in a location near exhaust hoods since this will increase the temperature whereby the control will not activate the mats.
4.6 After a deicing cycle is complete my pavement still has some snow on it. Why?
You should try adjusting your Delay Off cycle longer to allow the deicing system to clear all of the snow and dry the surface. The Delay Off adjustment 12 o’clock position is 30 minutes moving to 90 minutes at 3 o’clock. If this does not cure the problem or if snow removal is patchy, check to see if the deicing system itself is working properly.
4.7 The sensor relay is closed but the deicing system is not running. Why?
The heating system will be supplied by a different breaker that the one supplying power to the sensor. Make sure that this load breaker is closed. Are you using a sensor load contactor? Confirm that this contactor is working properly. Check to see if any included thermal overloads are not tripped.You might also find some additional helpful information by copying the following URL into your browser: http://www.doityourself.com/stry/troubleshooting-common-magnetic-contactor-problems#b
4.8 The temperature is below 15 degrees F, it is snowing and my sensor hasn’t triggered. What’s wrong?
Check the configuration switch. You likely have LTC (Low Temperature Cutoff) turned on. This will prevent triggering the snow removal/deicing system below 15 degrees F. In the on position, the assumption is that snow at very low temperatures tends to be very dry and should not be a problem. Of course, this is not always the case. If LTC is on, switch it to off.
5.1 Does the DS2 have a low voltage operation mode?
No. Additionally, the DS2 is requires at least a 100 volt power source and our snow melting mats require a minimum of 120 volts and a maximum of 240 volts.
5.2 Can the DS2 handle more than 30amps? Can the DS5 utilize more than the 2/30 amp relays?
As standalone units this is correct. However, when you use contactors in conjunction with the DS2/DS5, you can effectively extend your amperage needs to satisfy your mat configuration.
5.3 Can I heat any amount of surface area?
This is not necessarily true. You need to check the amperage your electrical service can handle. Most newer constructions handle 200 amps. Contact your service provider for details regarding upgrading your electrical service and factor this into the total cost of your product.
