Application Description
PARALLEL OFF 30 2566,
2567
When flow rises above this value, the parallel fan
will turn OFF.
CLG FLOW MIN 31 All except 2597 The minimum amount of air in CFM (LPS) to be
supplied to the space in cooling mode.
CLG FLOW MAX 32 All except 2597 The maximum amount of air in CFM (LPS) to be
supplied to the space in cooling mode.
HTG FLOW MIN 33 All except 2560,
2597
The minimum amount of air in CFM (LPS) to be
supplied to the space in heating mode.
HTG FLOW MAX 34 All except 2560,
2597
The maximum amount of air in CFM (LPS) to be
supplied to the space in heating mode.
AIR VOLUME {35}
2
All Actual amount of air in CFM (LPS) currently
passing through the air velocity sensor.
FLOW COEFF 36 All Calibration factor for the airflow sensor.
MTR3 COMD {37} 2560, 2561, 2562,
2597
The value to which the Motor 3 actuator is
commanded in percent of full value.
VLV2 COMD {37} 2563 The value to which the valve 2 actuator is
commanded in percent of full travel for applications
using a second water valve.
MTR3 POS {38} 2560, 2561, 2562,
2597
The current position of the Motor 3 actuator in
percent of full travel. This value is calculated based
on motor run time.
VLV2 POS {38} 2563 The current position of Valve 2 in percent of full
travel. This value is calculated based on valve run
time.
MTR3 TIMING 39 All except
2564, 2565, 2566,
2567
The time required for the Motor 3 actuator to travel
from the full closed position to the full open position.
DO 1 {41}
2
All Digital output 1 controls a 24 Vac load with an ON
or OFF status. If Motor 1 is enabled, DO 1 is
coupled with DO 2 to control an actuator.
DO 2 {42} All Digital output 2 controls a 24 Vac load with an ON
or OFF status. If Motor 1 is enabled, DO 2 is
coupled with DO 1 to control an actuator.
DO 3 {43} All except
2562, 2564, 2566
Digital output 3 controls a 24 Vac load with an ON
or OFF status. If Motor 2 is enabled, DO 3 is
coupled with DO 4 to control an actuator.
HEAT STAGE 1 {43} 2562, 2564, 2566 This point is DO 3 in applications with electric
reheat. This digital output controls the contact for
the first stage of heating and has a status of ON or
OFF.
