Mechanical Cooling COOL_LOCKOUT When the Mechanical Cooling Lockout Sensor 45
°
F
Lockout Setpoint is below this value, all mechanical cooling is
locked out. One degree accuracy, 10 to 70
°
F. A
value of Unprogrammed (or 0
°
F only)
disables this function.
Airflow Fail Delay AIR_FLOW_FL_DLY Delay from turning on the fan until 10 seconds
Airflow Failure, Dirty Filter, and Freezestat
are sensed. Failures are ignored when fan is
off. One second accuracy, 0-255 seconds.
Duct High Static Limit HIGH_STATIC_LIM Above this pressure limit, control is de- 5 inches
energized, alarm digital output turns on and an
alarm message is sent to the S7600. One-tenth
inch accuracy from 1.0 to 10 in. wc.
Duct High Static Duration HIGH_STATIC_DUR Control allows Duct Static Pressure above 9 seconds
Duct High Static Limit for a number of
continuous time periods before alarming and
de-energizing system. Three second time
period programmable, 0-765 seconds.
Low Discharge Air Limit LO_DA_LIM At or below alarm limit, the W7600 will send 35
°
F
an alarm message to the S7600 and turn off
all outputs.
Range = 10-50
°
F.
Discharge Low LO_DA_DUR Control allows temperature at Low Discharge 45 seconds
Limit Duration Air Limit for a number of continuous time
periods before alarming and de-energizing
system. Fifteen second time period
programmable, 0-3825 seconds.
Discharge Air TEMP_RATE_LIM When the Discharge Air Temperature 5
°
F/minute
Temperature Rate of changes faster than the programmed value,
Change additional cooling or heating capacity is
prevented from operating.
Range = 0 to 20
°
F/minute.
Discharge Pressure PRESS_RATE_LIM The programmed value is the limit allowed in 2 inches
Rate of Change the derivative portion of the total error used in per minute
the pressure control calculations. Effective only
when the derivative gain for pressure control
is unequal to zero. Range 0 to 5 in. wc/min.
Digital Input Debounce DEB_TIME0_ Control to ignore a digital input for this 0
DEB_TIME36 debounce time to avoid nuisance alarms.
One second accuracy, 0-255 seconds.
High Speed Fan Minimum HI_MIN_ON Defines minimum time high-speed fan digital
On Time output will be energized. Range = 1-20 minutes.
(Two-speed fan control.)
Warm-up Delay Time WU_DLY When mode changes from unoccupied to
occupied, control will delay
WARMUP_DELAY seconds before deter-
mining if warm-up sensor is below warm-up
setpoint, thus enabling warm-up mode.
