Notes
ACT COUNT (c) N/A 1 to 65,535 N/A
Displays number of times actuator has
cycled. 1 Cycle equals the sum of 180°
of movement in any direction.
ACTUATOR (c) N/A
OK/Alarm (on
Alarm menu)
N/A
Displays Error if voltage or torque is
below actuator range.
EXH1 OUT (c)
OFF
ON/OFF N/A
Output of EXH1 terminal. Displays ON
when damper position reaches
programmed percentage setpoint.
ON = 24 Vac Output; OFF = No
Output.
STATUS EXH2 OUT OFF
ON/OFF N/A
EXH2 OUT is not available.
ERV OFF
ON/OFF N/A
ERV is not available.
MECH COOL ON (c)
0
0, 1, or 2 N/A
Displays number of mechanical cooling
stages that are active.
FAN SPEED (c) N/A LOW or HIGH N/A
Displays speed of fan on a 2-speed fan
unit.
W (HEAT IN) (c) N/A ON/OFF N/A
Displays status of heat on a 2-speed
fan unit.
MAT SET (c) 53ºF
38 to 70°F;
increment by 1
53ºF
The economizer will modulate the OA
damper to maintain the mixed air
temperature at the setpoint.
LOW T LOCK
(c) 32ºF
-45 to 80°F;
increment by 1
32ºF
Setpoint determines outdoor
temperature when the mechanical
cooling cannot be turned on.
Commonly referred to as the
Compressor lockout. At or below the
setpoint the Y1-O will not be energized
on the controller.
DRYBLB SET (c) 63ºF
48 to 80°F;
increment by 1
67ºF
Setpoint determines where the
economizer will assume outdoor air
temperature is good for free cooling;
e.g.; at 63ºF setpoint unit will
economizer at 62ºF and below and not
economize at 64 ºF and above. There
is a a 2ºF deadband.
SETPOINTS ENTH CURVE (c) ES3
ES1, ES2, ES3,
ES4, or ES5
ES3
Enthalpy boundary “curves” for
economizing using single enthalpy.
See
Table 9, p. 17 for description of
enthalpy curves.
DCV SET (c) 1100ppm
500 to 2000 ppm
increment by 100
1100 ppm
Displays ONLY if a CO
2
sensor is
connected. Setpoint for Demand
Control Ventilation of space. Above the
setpoint, the OA dampers will
modulate open to bring in additional
OA to maintain a space ppm level
below the setpoint.
MIN POS (c)
2.8V 2 to 10 Vdc
2.8V/3.2V LO/
2.8V HI
Displays ONLY if a CO
2
sensor is NOT
connected. With 2-speed fan units MIN
POS L (low speed fan) and MIN POS H
(high speed fan) settings are required.
Default for MIN POS L is 3.2V and MIN
POS H is 2.8V.
