Reasons for alarms to activate
The Err message appears when an incorrect key has been pressed or if an attempt has
been made to change a parameter while memory protect is on. The Err message will
appear for 2 seconds and then disappear.
The high temperature alarm appears when the room temperature is above the high

alarm may occur on very hot days when the desired room temperature can not be
maintained.
