ECM2 Blower Operation

Fan speeds will be selected through the user interface or the facility management system. There will be a total of 12 speeds selectable with only three being selected at any one time. The lowest numbered speed selection set to ON will select the low-speed fan setting, the middle selection set to ON will select the medium-speed fan setting and the highest selection set to ON will select the high-speed fan setting. If all selections are set to OFF the software shall select speed setting 10 for low-speed, 11 for medium- speed, and will select speed setting 12 for high speed. If only one selection is set to ON, that selection will set the low-speed fan setting, the medium-speed setting will be 11, and the high-speed setting will be speed 12. The maximum low-speed setting will be speed 10 and the minimum high- speed setting will be speed 3. In addition there is a low limit setting in the software to prevent the ECM2 fan speed from being set below acceptable limits for each unit size.

ECM2 Fan air flow “Soft Switch Settings”

A set of 12 “soft switches” accessible through the user interface or building automation system are used to select the three fan speed settings for the ECM2 fan motor.

The 12 soft switches work in exactly the same way as the hardware switches used on the Premier control (Refer to Fan Performance Data - ECM2 Motor for proper settings). No more than three soft switches may be set to the “ON” position. The first “ON” switch (the lowest number switch) determines the “low speed fan” setting. The second de- termines the “medium speed fan” setting, and the third determines the “high speed fan” setting.

Inputs & Outputs Configuration

Field Selectable Options

Water Coil Low Temp (Freeze Sensing) Limit Set Point (BI-5) The water coil low temperature (freeze sensing) limit set point input allows you to adjust the water coil low tem- perature (freeze sensing) limit set point (AI-5). When the jumper is installed on BI-5 (Wire #24) the water coil low temperature (freeze sensing) limit set point is factory set for 30°F. When the jumper on BI-5 (Wire #24) is removed the water coil low temperature (freeze sensing) limit set point will be 15°F.

Accessory Outputs (BO-7 and BO-8)

Accessory Output 1 will be energized 90 seconds prior to the compressor output being energized. Accessory Output 2 will be energized with the fan output (BO-1). When the corresponding compressor output is turned off the acces- sory output will be deactivated immediately. These outputs are selectable for normally open or normally closed opera- tion through the Medium User interface or through the Building Automation System.

Emergency Heat/Network Enabled Output (BO5)

This output is set from the factory to enable/disable emergency heat. If a problem occurs with the unit result- ing in the compressor being locked out in heating mode, the control will automatically enable this output to turn on field installed electric heat. This output is interlocked with the fan proving input BI-6 (Fan proving sensors must be field supplied and installed). BI-6 must be connected to PB2 position 3 (see unit schematic) in the field if no fan proving sensor is desired. There is a configurable parame- ter available through a BAS network that must be enabled if this output is to be commanded over the BAS network.

MUI Alarm History Reporting

If a fault occurs the fault will be recorded in history for display on the medium user interface in the History Menu. Each fault type will be displayed in the history menu with a number between 0 and 3. A reading of 3+ will mean that fault has occurred more than three times in the past. The history menu can be cleared with a power cycle only. Alarm date and time are not included in the history.
