Description
Sets PID control of bypass damper for all modes, ventilation, cooling, heating
and smoke alarms.
PID Proportional constant
PID Integral constant
PID derivative constant
Supply static pressure setpoint during smoke alarm. Typically 1 to 1.5"w.c.
Supply static pressure setpoint during ventilation only. Typically 1 to 1.5"w.c.
Supply static pressure setpoint during heating. Typically 1 to 1.5"w.c.
Supply static pressure setpoint during cooling. Typically 1 to 1.5"w.c.
Minimum output to bypass damper during smoke alarm, ventilation only and
cooling. Sets minimum air delivered. Bypass damper motor is set to 10 to 2
volts with 10 v being closed.
Minimum output to bypass damper during heating. Sets minimum delivered.
Maximum output to bypass damper for all modes. Sets the maximum air deliv-
ered.
Bypass damper manual reset value output. Output when blower is off.
Supply static shutdown setpoint. Unit will shutdown for ECTO 5.02 minutes if
duct pressure exceeds this value for 20 seconds
The number of occurrences before permanent lockout. Counter resets when
M2 resets.
A value of 0 will disable lockout.
Sets PID control of VFD all modes, ventilation, cooling, heating and smoke
alarms.
VAV supply static pressure setpoint during smoke detection.
VAV supply static pressure setpoint during ventilation.
VAV supply static pressure setpoint during heating.
VAV supply static pressure setpoint during cooling.
Supply minimum speed for cooling, ventilation or smoke.
If minimum is >= manual reset (ECTO 0.09), then manual reset used is
shifted to (ECTO 0.07 + ECTO 0.08) / 2
Supply minimum speed for heating.
If minimum is >= manual reset (ECTO 0.09), then manual reset used is
shifted to (ECTO 0.06 + ECTO 0.08) / 2
Supply maximum output.
Supply PID manual reset value.
