Hog Slat Inc. Newton Grove, NC USA May 2024 REV IR 17 Ventilation System ================================================================== 17. COOLING: All stages can provide cooling. Stage 1 and 2 are variable speed output while Stages 3-6 are constant speed relay output. 17A: STAGE 1: Variable output stage. BW1 is the temperature range between when the stage operates at minimum speed up to full speed. MIN. VENT temperature and below is the temperature at which the fan is running at minimum speed. As the temperature goes up, the fan speed increases proportionally until temperature is equalled to “FULL SPEED” temperature at which time the stage 1 fans will be at full speed. 17B: STAGE 2: Variable output stage. OFFSET 2 is the temperature above stage 1 when the stage 2 fan(s) turn on. BW 2 is the temperature range between when the stage operates at minimum speed up to full speed. Example shown above, stage 2 turns on at 72F and runs at minimum speed. Speed will proportionally increase as temperature increases to 73. At this time stage 2 fans will be operating full speed. 17C. STAGE 3: ON/OFF output. DIFF (3) equals the temperature above stage 2 when stage 3 is to come on. Stage 3 turns off when temperature falls below the OFF temperature setting. 17D. STAGE 4: ON/OFF output. DIFF (4) equals the temperature above stage 3 when stage 4 is to come on. Stage 4 turns off when temperature falls below the OFF temperature setting. 17E. STAGE 5: ON/OFF output. DIFF (5) equals the temperature above stage 4 when stage 5 is to come on. Stage 5 turns off when temperature falls below the OFF temperature setting. 17F. STAGE 6: ON/OFF output. DIFF (6) equals the temperature above stage 5 when stage 6 is to come on. Stage 6 turns off when temperature falls below the OFF temperature setting. 17A 17B 17C 17D 17E 17F
