K, Z Series Landmark and Raider Rooftop Units
Product Information:
The Commercial Training Toolbox Tips provide guidelines for
setting up the economizer for KG/KC/KH and ZG/ZC/ZH Units with a
Siemens Climatix ECO Economizer Controller. The instructions apply
to Lennox Landmark and Raider Rooftop Units that have a factory or
field-installed economizer with a Siemen’s Climatix ECO controller.
An economizer uses a combination of sensible and enthalpy sensors
to determine when outside air is suitable for free cooling. The
type and number of sensors depend on the controller. The product
comes with installation and service literature that can be accessed
from LennoxCommercial.com or LennoxPros.com. The product also
provides self-service technical support with no wait times, service
videos on Lennox Commercial YouTube Channel, and Training Toolbox
Tips.
Product Usage Instructions:
To use the Commercial Training Toolbox Tips, follow the below
instructions:
- Ensure that you have a Siemens Climatix ECO Economizer
Controller installed on your KG/KC/KH or ZG/ZC/ZH Units. - Refer to the installation and service literature available on
LennoxCommercial.com or LennoxPros.com for detailed information on
how to set up the economizer. - Use the enthalpy and sensible sensors provided in the product
to measure return air and outside air enthalpy and
temperature. - Use the WLAN Stick Wi-Fi dongle to connect to the mobile device
app for remote monitoring and control of the economizer. - Enable free cooling operation when conditions are favorable by
comparing the return air enthalpy with outside air enthalpy sensor
for control. - Use the discharge air sensor to measure the temperature of the
air after the cooling coil. - Download all Training Toolbox Tips and register for Technical
Training Webinars to enhance your knowledge and skills on using the
Commercial Training Toolbox Tips.
