Aux control
About this task:
The TEC has an auxiliary output that can be configured to
operate in a few different ways. The Aux Mode supports
the following options:
• Not Used—Output is always off
• Occupied NO—Output is normally open, but closes
when occupied
• Occupied NC—Output is normally closed, but opens
when occupied
• Occupied Fan NO—Output is normally open, but is
closed when occupied with the fan running
• Occupied Fan NC—Output is normally closed, but is
open when occupied with the fan running
• On—Output is turned on (relay closed), used by a BAS
to directly control the AUX output
• Off—Output is turned off (relay open), used by a BAS to
directly control the AUX output
To set the Aux Mode, complete the following steps:
1. Press the Menu icon.
2. Press Setup.
3. Press General Setup.
4. Press Aux Mode and set accordingly.
5. Press Save and the back arrow to return to the
previous screen.
This option is also exposed to the BAS through the point
AUX-MODE.
When the Reheat installed parameter is set to True, the
Aux output is used for Reheat Output. The setting for the
Aux Mode is ignored when reheat is enabled.
Commissioning mode
About this task:
You can quickly test equipment wiring and functionality
with the thermostat controller's built-in commissioning
mode. The commissioning mode temporarily disables
the control logic and you can then manually command
any individual output. Commissioning is designed as the
last step of the installation process after configuring the
controller for the equipment being controlled, and the
available options in commissioning mode are dependent
on the controller configuration. To enter commissioning
mode, complete the following steps:
1. Press the Menu icon.
2. Press Setup.
3. Select Commissioning.
4. Confirm that the selection was intentional. (The
control is overridden upon selecting Confirm).
Individual outputs can be commanded through this
interface. For binary outputs, the options are Off or On;
for analog outputs, they can be commanded from 0 to
100%. Whenever a control output is turned on, the fan
is engaged for safety purposes. To command an output
from the Commissioning menu, complete the following
steps:
1. Select the output to command. Adjust the value to
the preferred output and press Save. The output
immediately changes to that value.
2. Restore the value to the original setting and press
Save once again to complete testing that output.
Pressing the back icon from the main commissioning
menu or allowing the menu system to time out and return
to the home screen ends commissioning and puts the
control logic back in control of the outputs.
Scheduled circulation
About this task:
You can schedule to run your fan for a minimum duration
per hour in order to maintain circulation in a space. If
the minimum hourly fan runtime is not exceeded as part
of normal HVAC operation, the fan turns on at the end
of the hour for the length of time required to fulfill the
minimum hourly run time. The fan runtime calculation
includes runtime initiated when the Fan Mode is set to
On and other overrides. The fan does not turn on if the
fan runtime is already longer than the minimum hourly
fan runtime. When you enabled the Scheduled Circulation
Only When Occupied setting, the fan does not turn on at
the end of the hour to fulfill the minimum runtime unless
the occupancy state is set to Occupied.
To set the Scheduled circulation, complete the following
steps:
1. Press the Menu icon.
2. Press Setup.
3. Press General Setup.
4. Press Scheduled Circulation and select Enable
5. Press Minimum Hourly Fan Runtime and set the
time in a range of 5 to 30 minutes.
6. Press Scheduled Circulation Only When
Occupied and select Disable or Enable as
required.
7. Press Save and the back arrow to return to the
previous screen.
