The TEMP Display indicates that the control cabinet
temperature has exceeded 155ºF (68ºC). If this occurs,
the unit must be turned off for at least 20 minutes so
that it can cool off and reset.
If this condition reoccurs, contact your Authorized
Service Agency or Roundup Technical Assistance.
The control board monitors the control cabinet ambient
