To avoid unwanted tampering of the required hot water tem-
perature the CET2000B-RF includes a key lock feature which
disables the Λ and V buttons.
First set the required hot water temperature using the Λ or V
button. Then slide internal DIL switch 4 to the locked posi-
tion and mount the CET2000B-RF back on its wallplate (as
shown on page 9).
