* The left thermostat will be wired to control your heater. The right thermostat is going to act as back up to ensure that in the event of the unlikely but possible left thermostat failure, it will be able to prevent an overheating situation for your heater. This is very important! Calibrate your cage temperature based upon your left thermostats reading. Then set your right thermostat just two degrees higher than the left. In this way your right thermostat will always be monitoring the temperature of your heat source and will turn off in the event that the temperature rises just two degrees above the desired temperature at your heat source.


Double checking the operation of both thermostats

You can periodically double check your thermostats to make sure they are working by simply doing the following:

1. Adjust the setting of your left unit up three degrees higher than your real desired setting.
2. Stay with your thermostat and watch as the temperature will rise fairly quickly in the next few minutes. When that temperature reaches the level set by the right thermostat it will kick in and turn off the power to the left thermostat.
3. This will be your indicator that your thermostats are operational.
4. After the temperature drops low enough for the left thermostat to come back on again return it to the original desired temperature. You are ready to go.



Troubleshooting error messages

Display

 Messages  To correct

 E1

 Appears when either the up or down key is pressed when not in the programming mode  If the E1 message appears even when no keys are being pressed, replace control.

 E2

 Appears if the control settings are not properly stored in memory.  Check all settings and correct if necessary.

 EP

 Appears when the probe is open, shorted or sensing a temperature that is out of range.  Check to see if the sensed temperature is out of range. If not, check for probe damage by comparing it to a known ambient temperature between -30F and 220F. Replace the probe if necessary.

 EE

 Appears if the EPROM dada has been corrupted.  This condition cannot be field repaired. Replace the control.

 CL

 Appears if calibration mode has been entered.  Remove power to the control for at least five seconds. Reapply power. If the CL message still appeared, replace the control.


How to set up your thermostat including probe placement

Your Boaphile Plastics Thermostat is an industrial grade thermostat that will give you great service for many years to come. Paramount to the proper use of your thermostat is understanding how to set up your thermostat and exactly what it will do for you. Your thermostat comes with a long cord attached to the temperature probe. This probe is what will run your heating device(s) at whatever temperature you set your thermostat at. The closer your probe can be placed to that heat source the more accurately it will be able to maintain the temperatures you will require for your animals.

Every situation is unique and the many different animals housed in our or other folk's caging systems may require different heater temperatures to maintain the temperatures your animals require. For instance, if you are heating a single cage in a 68 degree room, your heater will necessarily have to run much warmer to maintain the minimum temperatures required at the cool end of a cage than if your room temperature is 78 degrees. Let me be more specific; when keeping Boa Constrictors I want the cool end of my cage to be 80 degrees. The warm end is warmer than this and in my case with my room at 76 degrees and all of my cages stacked tightly; I set my temperature at my hot spot at only 85 to 87 degrees. My hot spot is not necessarily the same size as yours is either. I use Aspen bedding and so my hot spot is warmer than it was when I used newspaper exclusively. So you can see that if your room is cooler and if you are heating a single cage and your heater may or may not be identical to mine and your cage may be a different size as well. Your substraight will have an impact on how your heating system works as well. All of these things together mean that you will need to be able to calibrate your heat source to your own unique situation.

Now be aware that the temperature of your heat source will necessarily be different than the overall temperature of your cage. Remember given my own set up my heat source is only set at 85 to 87 degrees to maintain 80 degrees at the cool end of my cage. Your situation may require a hot spot of 95 degrees to maintain 80 degrees at the cool end of your cage.

All that being said, setting up your cage/rack(s) should be easy to do. The best ways to maintain the steadiest temperatures possible is to make sure you have the sensitivity of your thermostat set to within 1 degree sensitivity. We ship our thermostats preset to this level. Next is to fully tape your temperature probe(s) onto your heat source. When monitoring a rack, tape the probe(s) onto the Flexwatt nearest the side so that your tubs do not bump into the probe itself. The only exceptions to taping the probe onto the heaters are higher temperature heaters like radiant heat panels, ceramic heat emitters and lights. These all require that the probe be set somewhere else in the cage as they just get too hot for the probe to work effectively. When the probe is taped fully over the heat source; this allows the heat to be measured as closely as possible to the heater itself. This close-as-possible monitoring will allow you to keep your temperatures as steady as possible. This is also the best way to keep your probe clean if it is installed directly inside the cage which is perfectly acceptable. The only other thing to remember is your thermostat is used to set the temperature of your heater and not the temperature of your cage. You will need to set up your thermostat and probe and test the temperature setting you will use at the heater to achieve the temperature you really want inside the cage/rack. As I mentioned earlier, this temperature will vary each individual set up. A good rule of thumb is to first try setting the temperature of the heater at 5 degrees warmer than your ultimately desired temperature of the cage/rack. Allow the set up to run for several hours before making any change. Using a separate temperature measuring device, you should monitor the temps in the cage/rack or check it periodically to see how close you are getting to what you would like to see. Continue to move the temperature set on your thermostat up until the temperature in your cage/rack(s) is where you would like it. Next after all is set up be sure to double check again several hours later to make sure everything is set properly and your set up is ready for the animals.

Your thermostat will control 1500 watts of heaters power. I would recommend not running more than 20 heaters on a single or double thermostat set up because of the voltage loss you will suffer just due to all the cords. However, banks of cages and stacks of racks can be run off of one Boaphile Plastics Thermostat set up.
