Specifying Motor Setup

MTR SETUP determines which actuators are controlled by the application and whether

they are direct or reverse acting. Set MTR SETUP according to Table

MTR SETUP

Values

NOTE:

When MTR SETUP is changed, all enabled actuators will calibrate. Wait until

each actuator has completed its calibration before continuing.

MTR SETUP Values

Motor 1 (Damper)

Enabled Enabled and Reversed

Motor 2

Not Used 1 (default) 3

Enabled 5 7

Enabled and Reversed 13 15

Verifying Actuator Setup

1. Command all actuators closed. Verify that they close and remain closed. If not,

adjust the setting for MTR SETUP according to Table

MTR SETUP Values

2. If any of the actuators still do not close completely, then the actuators have been

installed or set up incorrectly. See the installation instructions (550-031), the iKnow

Troubleshooting Tool, or contact Field Support.

Setting Number of Heat Stages

Depending on the application, HTG STG CNT (if present) refers to electric heat stages

used (enabled), some point names may vary.

 For electric heat applications, check the hardware to verify the number of electric

heat stages wired to the controller (1 to 3 stages without fan or 1 to 2 stages with

fan) and set HTG STG CNT to this value.

CAUTION

For installations using electric heat coils, never set min airflow settings to 0.

Equipment damage can occur if electric heat is on without airflow.
