1. Safety notes
The FXK cable remotes enables the instantaneous water heaters DEX, DSX, DCX and DBX to be comfortably con-
trolled even if the appliance is relatively inaccessible and the temperature consequently cannot be set as required.
The communication between the cable remote and the instantaneous water heater is bi-directional. Due to this
technology the data transfer is secured even under difficult installation conditions.
Note: A single FXK is used for one device only! There is no priority circuit between the cable remote and the set-
ting options at the appliance. All operation modules are coequal. Please observe that by interference of a second
user the water outlet temperature can change. The cable must be installed, sheltered and protected against exces-
sive traction.
