Issue The word TEST is displayed on the Liquid Crystal Display screen of a Satchwell Climatronic Controller when first powered up during initial installation preventing it from being commissioned. Environment Satchwell Climatronic CSC5252 CSC5352 CXR5805 CXT5605 CZT5305  Controller Display TEST LCD Screen Cause The cause of the word TEST being displayed on the Liquid Crystal Display screen of a Satchwell Climatronic Controller when first powered up during initial installation and preventing it from being commissioned is normally due to a micro processor programming error occurring during the course of production. Resolution There is no field remedy that can be applied to a Climatronic Controller displaying the word TEST on the Liquid Crystal Display screen that will enable it to be commissioned successfully. The Controller should therefore be returned to the vendor for replacement under the terms and conditions of the warranty applicable at the time of purchase.
