Tate SmartAire M User manual

Advanced SmartAire M and PowerAire M
Controller Guide
Tate’s SmartAire and PowerAire M units are factory configured for
optimal performance in a typical data center environment. The
installation of these units in most data center space will result in ideal
performance without any user intervention.
Some sites however have differing requirements, and the application
of SmartAire and PowerAire M units may not be ideal based on a
number of site conditions. These requirements have prompted Tate
to publish an advanced guide to the SmartAire and PowerAire M
controllers which will allow the expert user more precise control over
the functionality of Tate’s product.
This document is intended to be only a guide to the operation of the
embedded controller. The user takes full responsibility when
adjusting the default parameters set in all PowerAire and SmartAire
M units when they leave our factory. Adjusts to these parameters
may result in undesirable operation of the units, as well as decrease
the life expectancy of the units themselves. It is suggest that only
those users with a high level of experience in control methodology
attempt to make these changes without direct consultation with
Tate’s data center product management team.
Please feel free to contact Tate with any questions regarding this
operations guide.

We would be very interested to hear any comments you might have
on this new guide. We are particularly interested in learning of
omissions or subjects that are unclear. Please call, fax, or e-mail and
direct your comments to Technical Service. Thank you very much for
your assistance.

45.0 Proportional Term Current
Setting
SEL
The default Pb value is 45, if the unit seems too slow in responding in your
environment, decrease the value to achieve a quicker response
45.0 SEL
Default value is 45.0. Adjust the Proportional term as required, higher numbers reduce
the effect of the proportional term, lower values increase the effect. Press SEL to save

it Integral Term
Configuration Prompt
SEL
This value allows the user to adjust the integral term of the PI or PID loop. Note that
the I terms is only displayed if the controller type is set to PI or PID
110 Integral Term Current Setting
SEL
This value adjusts the effect of the integral term of the PI or PID controller, this value
examines the current difference in the set point, as well as historic error, to determine the
change in set point. Increasing this value increases the time the controller examines older
data, decreasing it shortens the window of data examined
Proportional Term Setting
Adjustment
110 SEL
Default value is 110. Adjust the integral term as required, higher numbers increase the
effect of the integral term, lower values decrease the effect. Press SEL to save the

dt Derivative Term
Configuration Prompt
SEL
This value allows the user to adjust the derivative term of the PID loop. Note that the
D terms is only displayed if the controller type is set to PID
0SEL
This value adjusts the effect of the derivative term of the PID controller, this value
examines the rate of change in the historic temperature values. The faster the temperature
is changing, the more effect the derivative term will have on the fan speed or damper
setting. The higher the value of derivative term constant, the slower the reaction of the unit
will become, but a lower level of steady state error and less overshoot will be realized.
0SEL
Default value is 0. Adjust the derivative term as required, higher numbers increase the
effect of the derivative term, lower values decrease the effect. Press SEL to save the

dB Dead Band Value
Configuration Prompt
SEL
This value allows the user to adjust the dead band of the temperature values before
any action is taken by the controller to adjust the settings. This dead band is +/- the
current temperature setpoint
1.0 Dead Band Value Current Setting
SEL
This value represents the current dead band of the controller where no action will be taken
by the control system to either increase or decrease fan speed or damper position.
1.0 SEL
Default value is 1.0. Increasing the dead band will result in fewer input changes to the system,
and will likely result in a higher level of SmartAire or PowerAire control stability. Lower values
will result in tighter control over the output temperature, but will result in more frequent
changes in fan speed or damper position. Press SEL to store the new value.

add Address Configuration
Prompt
SEL
This value allows the user to adjust the address of the unit when connecting the unit to
a BMS interface via a serial link between units.
1SEL
This value assigns the unit an address on the Carel I/O bus when units are linked serially
together to a master unit equipped with a BMS interface card.
1SEL
Default value is 1, units should be assigned in order, with the unit equipped with the
BMS card assigned the address value of 1, with each unit in the chain being assigned
the next higher number.
