Installation of the unit is relatively simple (so says the person who designed it)! :)
Notes for Installation
- Reference the instructions, you cannot install this without following the instructions for programming!
- Consider the best location to for the controller and the sensor.
- The controller does not need to be fully accessible but should be somewhere where remember where it's at and can reach if if necessary.
- The sensor should never be in contact with a component or anything metal, it should be set to where it's reading the air temperature, not surface temp.
- Consider the best way to route the power and fan wires (a little thought ahead of time makes it all easier later)
- It may be easier to mount the unit using velcro if the unit is in a place that is difficult to reach. If using velcro, make it so the unit can be easily pulled out and serviced.
Installation
Determine the best location for the unit which is determined by accessibility for the power supply, the location of the fan unit/s and area seeking to cool. Do not place the controller or sensor on a component, it is best to screw, zip tie, or velcro to the side of the cabinet or rack and mount the sensor so it also is not in contact with equipment. When venting equipment (exhausting air out of a cabinet or enclosure) it may desirable to put the sensor in the airflow pathway of the fan as that is a good measure of the ambient temperature in the closet.Once location is determined, power the unit with the power supply, some controllers come with a 2-pin power connector while other’s come with 2.1mm coax, for the 2-pin ensure to Align to + on the connector ends and for the 2.1 Coax, the center pin is +. The unit is polarity protected so mis-wiring will not damage the unit but it will not operate with incorrect polarity.
Once the unit is powered it can be programmed following the instructions below and fans can be plugged in at any point but also ensuring proper polarity. Multiple fans up to 2.5A can be connected using Y or Tri-Cables sold separately.
Programming
Fan Mode Programming. For programming the fan mode, press the programming button once and the unit will beep once, this indicates it is in programming mode. Within 5 seconds press the button corresponding to the desired mode, for example 3 times for Mode 3 (fans on at 90°F). Once desired mode is input wait and the unit will beep to confirm that selected mode (3 beeps for mode 3 for example).
Alarm Programming. Press and hold the button for 3 seconds, the unit will beep, press for desired Mode. 1 press for Mode 1 (Off), 2 presses Mode 2 (Alarm at 115°F), 3 presses Mode 3 (Alarm at 125°F).
