Please read the full instructions as this is just the highlights and key points!
Installation with this unit is actually very easy. It is either rack mounted or just sits on a shelf or component so select the desired and proper location. If rack mounting, install the rack 'ears' and if using set top, install the rubber 'feet'. Also, before installing the unit, insert the fan and sensor wires and ensure they are seated properly (press in the tab firmly and then insert the wire, once inserted, give a little tug). Testing the unit prior to installation is good to confirm the wires are properly installed and seated.
Ensure that the sensors are not simply placed on a component, it should be located to read the air temperature, not component surface temp. The sensors can also be placed in the path of airflow.
Multiple fans can be connected and controlled using Y, Tri and Extension Cables (purchased separately). Make certain not to exceed 2A for each bank of fans and 5A max for the unit.
For programming, auto mode should be used for the control type and also for fan speed. The only things should program is the On set point, the High Speed Set Point, and the Alarm. This means press the Programming button and the first setting is the On setpoint, the next is the High Speed and the 3rd is Alarm. Set around 80 for rooms and closets, between 90 and 100 for use inside cabinets and enclosures and 100-110F for secondary cooling. Alarm is normally set between 115 and 125F.
If wish to use the contact closures, ensure to use the proper location for NO and NC. The relays will be activated on alarm and then will 'release' when the alarm is deactivated.
