Recently, a customer reflected that there was a problem with a CW-5000 chiller, the temperature controller display E1 code alarm which means over high room temperature alarm. Generally speaking, when the room temperature is over 40℃, the alarm sounds. However the room temp around 20℃ at that time. Therefore, the customer doubted the room temperature sensor to be the problem.

Regarding room temperature alarm with S&A chiller CW-5000

Firstly, we suggest to restore to factory setting, the operation step as below:
Before machine startup, press and hold ▽△ bottons until the controller displays rE, 6seconds later releasing the buttons, all parameters values setting of the controller have been restored to factory settings.
Regarding room temperature alarm with S&A chiller CW-5000
Please press ▽ botton to show the room temperature. If the room temperature displays in normal, the sensor is failure, we should change it.
As the chiller CW-5000 works in defaulted intelligent control mode. The water temperature is adjusted according to room temperature. Now we should change to constant temperature mode which needn’t temperature sensor work and can constant at a certain temperature. 

After you replace a new sensor,and restore to factory setting again.
