Application Description 
MTR2 POS 
{53} 
2560, 2561,  2597 
The current position of the Motor 2 actuator in 
percent of full travel (for use as an auxiliary slave 
point). This value is calculated based on motor run 
time. See MTR2 TIMING. 
VLV POS 
{53} 
2565  
The current position of the valve in percent of full 
travel for applications using a water valve. This 
value is calculated based on motor run time. 
VLV1 POS 
{53} 
2563 
The current position of valve 1 in percent of full 
travel for applications using a water valve. This 
value is calculated based on motor run time. 
MTR2 TIMING 
55 
All except  
2562, 2564,  2566 
The time required for the Motor 2 actuator to travel 
from full closed to the full open position. 
DMPR ROT ANG 
56 
All except 2597 
The number of degrees the damper is free to travel. 
DPR1 ROT ANG 
56 
2597 
The number of degrees that damper 1 is free to 
travel. 
DPR2 ROT ANG 
57 
2597  
The number of degrees that damper 2, the hot duct 
damper, is free to travel. 
MTR SETUP 
58 
All 
The configuration setup code for Motors 1, 2, and 3. 
This enables the motors individually and sets each 
motor to be either direct or reverse acting.  
Note: When a motor is enabled, its associated DOs 
are enabled. 
DO DIR.REV 
59 
All 
The configuration setup code for DOs. Allows the 
DOs to be direct or reverse acting (enabled equals 
energized or disabled equals de-energized). 
EHEAT FLOW 
60 
2562 
The flow required before the electric heat will be 
enabled. 
COOL TEMP 
61 
2561 
The discharge air temperature where the controller 
will switch from heating to cooling mode. Used only 
in applications with SUPPLY TEMP. 
HEAT TEMP 
62 
2561 
The discharge air temperature where the controller 
will switch from cooling to heating mode. Used only 
in applications with SUPPLY TEMP. 
CLG P GAIN 
63 
All except 2597  
The proportional gain value for the cooling 
temperature control loop. 
CLG l GAIN 
64 
All except 2597  
The integral gain value for the cooling temperature 
control loop. 
CLG D GAIN 
65 
All except 2597  
The derivative gain value for the cooling 
temperature control loop. 
CHK OUT 
66 
All  
The procedure tests all of the necessary I/O and 
ensures the controller has the ability to operate 
within the set airflow range, between CLG FLOW 
MIN and CLG FLOW MAX. 
HTG P GAIN 
67 
All except 
2560, 2597 
The proportional gain value for the heating 
temperature control loop.
