Description

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.

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.

DO 4

{44}

All

except

2562, 2564, 2566

Digital output 4 controls a 24 Vac load with an ON or OFF

status. If Motor 2 is enabled, DO 4 is coupled with DO 3 to

control an actuator.

HEAT STAGE 2

{44}

2562, 2564, 2566

This point is DO 4 in applications with electric reheat. This

digital output controls the contact for the second stage of

heating and has a status of ON or OFF.

DO 5

{45}

2560, 2561, 2563,

2597

Digital output 5 controls a 24 Vac load with an ON or OFF

status. If Motor 3 is enabled, DO 5 is coupled with DO 6 to

control an actuator.

DO 5

{45}

2565, 2567

Digital output 5 controls a 24 Vac load with an ON or OFF

status.

HEAT STAGE 3

{45}

2

2562, 2564, 2566

This point is a digital output used to control the contact for the

third stage of heating and has a status of ON or OFF.

FAN

{46}

2564, 2565, 2566,

2567

This point is a digital output used to control the fan. ON

indicates that the DO is energized; OFF indicates that the DO

is de-energized.

DMPR COMD

{48}

All

except 2597

The value to which the damper motor is commanded in

percent of full travel.

MTR1 COMD

{48}

2597

The value to which the Motor 1 actuator is commanded in

percent of full travel.

DMPR POS

{49}

All

except 2597

The current position of the damper motor in percent of full

travel. This value is calculated based on motor run time.

MTR1 POS

{49}

2597

The current position of Motor 1 in percent of full travel. This

value is calculated based on motor run time. See MTR1

TIMING.

MTR1 TIMING

51

All

The time required for the Motor 1 actuator to travel from full

closed to the full open position.

MTR2 COMD

{52}

2

2560, 2561, 2597

The value to which the Motor 2 actuator is commanded in

percent of full travel (for use as an auxiliary slave point).

VLV COMD

{52}

2565, 2567

The value to which the valve actuator is commanded in

percent of full travel for applications using a water valve.

VLV1 COMD

{52}

2563

The value to which the valve 1 actuator is commanded in

percent of full travel for applications using a water valve.

MTR2 POS

{53}

2560, 2561, 2597

The current position of the Motor 2 actuator in percent of full
