DESCRIPTION:

The Ranco ETC is a microprocessor based electronic temperature controller designed to provide on/off control of heating and cooling (Chillers) . The ETC is equipped with a Liquid Crystal Display(LCD) that provides a constant readout of the sensed temperature, and a touch keypad that allows the user to easily and accurately select the set point temperature, differential set point, and heating or cooling mode of operation. The unit can be operated on either line voltage, 120/208/240VAC. With its wide temperature setpoint range and selectable heating or cooling modes, the ETC can be used for a wide variety of applications such as Research, Science, Laboratory, Education, Aquariums, Hydroponics, Pools and more..

Some of ETC's outstanding features include:

Programming Procedures: Single Temperature Controller Double Temperature Controller Safety Check of your Thermostats Operation Troubleshooting error messages Probe placement and temp set up

Programing procedure for single temperature controller.

Steps	Procedure	Annunciator	Description	Display
Step 1	To start programming, press the SET key once to access the Fahrenheit/Celsius mode. The display will show the current status, either F for degrees Fahrenheit or C for degrees Celsius. Then Press either up or down arrow key to toggle between the F or C Designation.	F or C	Fahrenheit or Celsius Scale
Step 2	Press SET key again to access the setpoint. The LCD will display the current setpoint and S1 annunciator will be blinking on and off to indicate that the controls in the setpoint mode. Then press either the up key to increase or the down key to decrease the set point to the desired setting.	S1 (blinking)	Setpoint Temperature Your probe should be placed directly at the heat source. Your cage temperature must be calibrated based upon this temp.
Step 3	Press SET key again to access the differential. The LCD will display the current differential and DIF1 annunciator will be blinking on and off to indicate that the controls in the differential mode. Then press either the up key to increase or the down key to decrease the differential to the desired setting.	DIF 1 (blinking)	Differential Temperature "Boaphile Plastics" recommends setting at just "1" degree for greatest consistency.
Step 4	Press SET key again to access the cooling or heating mode. The LCD will display the current mode, either C1 for cooling H1 for heating. Then press either the up key or the down key to toggle between the C1 or H1 designation. Press the SET key once more and programming is complete.	C1 / H1	Cooling or Heating mode Of course the setting will be on "H1".

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 -30°F and 220°F. 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.
