Siemens Building Technologies, Inc. 

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. 

DO 6 

{46} 

All except  

2564, 2565,  2566, 

2567  

Digital output 6 controls a 24 Vac load with an ON 
or OFF status. If Motor 3 is enabled, DO 6 is 
coupled with DO 5 to control an actuator.  

In applications with CAL MODULE set to YES, this 
digital output controls the Autozero Module to 
calibrate the controller's internal air velocity 
transducer. 

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.
