Description
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 and 2. 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.
HTG l GAIN
68
All
except
2560, 2597
The integral gain value for the heating temperature control
loop.
HTG D GAIN
69
All
except
2560, 2597
The derivative gain value for the heating temperature control
loop.
CHK STATUS
70
All
Displays the results of CHK OUT.
FLOW P GAIN
71
All
except
2597
The proportional gain value for the flow control loop.
FLOW l GAIN
72
All
except
2597
The integral gain value for the flow control loop.
FLOW D GAIN
73
All
except
2597
The derivative gain value for the flow control loop.
FLOW BIAS
74
All
except
2597
The biasing of the flow control loop.
