Notice: Improper tuning of this temperature controller (or any temperature controller) can lead to excessive thermal cycling
and/or overheating of the thermoelectric device, either of which are known to reduce the lifetime of any thermoelectric device.
Care should be taken to prevent the temperature of the thermoelectric device from going beyond the range specified by the
device manufacturer. Care should also be taken so that any thermal cycling of the thermoelectric device is a result of changes
in the controller’s set-point temperature and not instability at a given set point due to improper selection of the tuning variables.
In no event shall TE Technology, Inc. be liable for any damages whatsoever (including without limitation, damage for loss of
business profits, business interruption, loss of business information, or any other pecuniary loss) arising out of the use or
inability to use this TE Technology, Inc. product, even if TE Technology, Inc. has been advised of the possibility of such
damages.
