DISCLAIMER AND WARRANTY DISCLAIMER By using the CoolBot temperature controller, you (the “User”) acknowledge there are inherent hazards in getting an air-conditioner (“A/C”) to do something it was not originally designed to do, and that these inherent hazards cannot be ameliorated, mitigated or obviated while still maintaining the essential functionality of the CoolBot. User accepts all responsibility in the use of and monitoring of the CoolBot and A/C.
KNOWING YOUR COOLBOT FIG. 1 During normal operation or after 20 seconds of inactivity the CoolBot goes into the “Room Mode” by default and the display shows the current room temperature. DISPLAY: The display changes depending on which Mode indicator light is illuminated. MODE INDICATOR LIGHT: Shows which mode you are currently using. Change modes by pressing the left or right arrows.
POWER INDICATOR LIGHT: This light is constantly on (solid), as long as your CoolBot is plugged in and getting the correct power supply (110V-230V). HEATER ACTIVITY INDICATOR: During normal operation and when “calling for cooling” this light will blink slowly. It will stop blinking if the room temperature has reached the “set point” or the fins are reaching the freezing set point. INPUT TOUCH KEYS CHECKMARK KEY: Press to enter the setup menu, save values, and exit each particular mode.
HOW DOES THE COOLBOT WORK? The CoolBot uses 2 sensors (ROOM and FIN sensors), the HEATER cable (red tip) and a programmed micro-controller to direct your air conditioner to operate in such a way as to cool the room to a set temperature in between 33°F/0.5°C and 65°F/18°C without freezing up. How does it do this? The HEATER cable (red tip) is keeping your A/C’s sensor warm to make the A/C “think” it is warmer than the actual room temperature.
BEFORE INSTALLING YOUR COOLBOT Please go through the following checklist before installing your CoolBot: ❏ The A/C Unit: ❏ Has digital display only. ❏ Is properly sized in BTUs according to storeitcold.com. ❏ Is of one of the recommended brands and models. ❏ Has Automatic Restart. For assistance on Sizing and Brand selection please visit our website at: https://www.storeitcold.com/ac-selection/ ❏ The A/C is installed: ❏ High up on the cooler wall (bottom of the A/C >5 feet/1.5 meters).
INSTALLING YOUR COOLBOT For videos and pictures about how to install your CoolBot please visit us at: https://www.storeitcold.com/install-your-coolbot/ STEP 1 ● ● ● STEP 2 ● ● STEP 3 ● ● ● STEP 4 ● ● STEP 5 ● ● Plug the wires into the labeled ports at the bottom of your CoolBot. Make sure you plug the wires in their corresponding ports according to the description in the KNOWING YOUR COOLBOT Section (Page 3).
FIG. 2 STEP 6 IMPORTANT! If your A/C Has a Secondary Sensor, IT MUST BE UNPLUGGED. ➢ ➢ ➢ Window LG and Haier units DO NOT have Secondary Sensors (skip to Step 7). Most window A/C units over 10K BTUs from GE, Kenmore, Frigidaire, ComfortAire, Arctic King, PerfectAire, Danby have a Secondary Sensor. All “Mini-Split” air conditioners have Secondary Sensors. For videos and pictures on removing secondary sensors check out our website at: https://www.storeitcold.
STEP 7 ● ● ● ● Use a pen/pencil to open a small gap in the fins about 1” from the bottom and near the center (horizontally), between the first and second horizontal cooling pipes. Take the cable sensor coming from the CoolBot port labelled “Fins” and gently insert just 1/4 inch (0.7 cm) of the TIP into the small gap. DO NOT force the sensor in, you'll damage it. Do not touch a coolant pipe with the FINS Sensor. You want to be between the bottom 2 horizontal cooling pipes.

CHANGING SETTINGS ON THE COOLBOT IMPORTANT! Please make sure you are familiar with the CoolBot parts and controls as described in the KNOWING YOUR COOLBOT (Page 3) and HOW DOES THE COOLBOT WORK? (Page 5) sections, before making any changes to the default setup. ROOM TEMPERATURE SETTING This setting is the average temperature you want to keep your room at. Note: The default temperature from the factory is set at 42°F/5.6°C.
HEATER DELAY SETTING This setting allows you to increase or decrease the defrost cycle time. If you are experiencing ice ups and the problem has not been solved by increasing your Fins setting, then raise your Heater Delay setting. NOTE: The factory default Heater Delay setting is “d1” 95% of CoolBot installations work well with settings in the SHADED zone.
TROUBLESHOOTING GUIDE If you are experiencing problems with your cooler please double-check all the requirements in the BEFORE INSTALLING YOUR COOLBOT (Page 6) section of this manual and make sure that you have followed all the steps in the INSTALLING YOUR COOLBOT (Page 7) section of this guide. “Er” SHOWING ON MY COOLBOT DISPLAY “Er” is a communication error with the ROOM sensor. ● Unplug the ROOM sensor from the CoolBot. ● Inspect the cable for possible damages in the cord or on the tip.
“Ef” FLASHES ON MY COOLBOT DISPLAY The Fins Mode Indicator light flashes rapidly. “Ef” is a communication error with the FINS sensor. ● Unplug the FINS sensor from the CoolBot. ● Inspect the cable for possible damages in the cord or on the tip. ● Clean the plug end (jack connector) of the sensor with a cotton cloth and plug it back in the CoolBot port a couple times making sure it goes all the way in. ● If the error persists after 20 seconds, the sensor is bad and needs replacement.
MY HEATER DOES NOT SEEM TO BE WORKING Checking the HEATER is very simple: ● Pull the HEATER out of the aluminum foil. Hold the red tip against the inside of your wrist with your fingers. ● Unplug the POWER to the CoolBot, then plug it back in. In ~5 seconds the Heater Activity Indicator light will come on SOLID for about 20 seconds. ● The HEATER should get Warm/Hot within the first 10-30 seconds of the CoolBot being plugged in. If not, unplug/plug the HEATER a couple times and repeat the test.
● ● ● ● ● ● ● Watch your A/C unit as it is cooling. Where does it start icing up? Reposition the FINS sensor to that area where the frost begins to form. If the problem persists after the previous checks, increase the Fins setting by 1 or 2 points. If the problem persists increase the Heater Delay setting by 1 or 2 points. If the problem persists keep stepping up the Fins Setting, then the Heater Delay, until problem is solved.
MY COOLER WAS RUNNING FINE AND NOW IT WON’T GET COLD ● ● ● ● ● Is the compressor running? Unplug the A/C unit and reset it following the instructions in the owner’s manual of your A/C unit. Are the fins clean? See DIRTY FINS (Page 15). Is your A/C in the “COOL” mode and the fan on “HIGH”? Did you check your HEATER foil connection? See INSTALLING YOUR COOLBOT-STEP 5 (Page 7). Did something change from the original setup? Please see MY ROOM WON’T GET COLD ENOUGH (Page 16).
You can run the A/C in “ENERGY SAVER” mode so the fan cycles off when the compressor stops running (and comes on every few minutes for a couple seconds to circulate air), but your room will cool slower and might not get quite as cold. You must change the Heater Delay setting to “d3” if running in “ENERGY SAVER” to avoid possible ice ups. Please see CHANGING SETTINGS ON THE COOLBOT (Page 12) to adjust your Heater Delay setting.
MY A/C UNIT ACCUMULATES A LOT OF WATER IN THE BOTTOM TRAY Depending on the conditions of your Cooler, construction, insulation, ambient humidity and other factors, your cooler may experience higher amounts of condensation. Most window A/C units nowadays are designed to run with up to ½” of water in the back part of the bottom tray and no drains.
