When the condition becomes TRUE, a START will be sent to the blower under the following restrictions:
(1) WIND DIRECTION ON DELAY - A START will not occur unless the wind direction is TRUE for the duration specified in Register 14 (Normally 6 seconds). If within 6 seconds, the direction becomes FALSE the process restarts and a START will not occur. Note – this process is fine-tuned by selecting several neighboring wind direction segments (Registers 1 thru 12) so wind direction can become TRUE in a broad general direction rather than one exact wind direction segment.
(2) LOW WIND SPEED ON DELAY - A START will not occur unless the wind speed is TRUE for the duration specified in Register 18 (Normally 6 seconds). If within 6 seconds, the speed becomes FALSE the process restarts and a START will not occur. Note – this process is fine-tuned by selecting wind speed thresholds in Registers 17 and 20 lower and higher than the problematic wind speed. For instance – if odor issues occur between 6MPH and 18 MPH, then the speed thresholds should be programmed to 4 MPH and 20MPH.
(3) HIGH WIND SPEED ON DELAY - A START will not occur unless the wind speed is TRUE for the duration specified in Register 21 (Normally 6 seconds). If within 6 seconds, the speed becomes FALSE the process restarts and a START will not occur. Note – again, this process is fine-tuned by selecting wind speed thresholds in Registers 17 and 20 lower and higher than the problematic wind speed. For instance – if odor issues occur between 6MPH and 18 MPH, then the speed thresholds should be programmed to 4 MPH and 20MPH.
(4) RESTART LOCKOUT – When a blower STOP occurs, a START cannot occur with the time period specified in Register 22 (Normally 60 seconds). If a START occurs after the time specified in register 22, the blower will start immediately. This supersedes all other START logic to protect the blower motor from an immediate restart.
When the condition becomes FALSE, a STOP will be sent to the blower under the following restrictions
(5) WIND DIRECTION OFF DELAY - A STOP will not occur unless the wind direction is FALSE for the duration specified in Register 15 (Normally 18 seconds). If within 18 seconds, the direction becomes TRUE the process restarts and a STOP will not occur. Note – again, this process is fine-tuned by selecting several neighboring wind direction segments (Registers 1 thru 12) so wind direction remains TRUE in a broad general direction rather than one exact wind direction segment.
(6) MINIMUM RUN TIME – When a START occurs, the blower will continue to run for the time period specified in Register 23 (programmed time depends on the size of blower motor, can be up to 16 minutes). This supersedes all other START / STOP logic to protect the blower motor from short cycling.
Note – there is no wind speed off delay – this argument is managed via simple on delays as discussed in points 2 and 3 above.
