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.
