2. Updating of the PCU-195 software version : F 1.5The new board is compatible with previous appliance versions.An updating of the software version of the PCU-195 board is not possible : replace the board if necessary. Apreventive replacement is not necessary.The software version is displayed when the appliance is switched on. The program version is also written on thelabel sticked on the board:

Following parameters added:

* = Minimum room temperature for compressor operation = Maximum room temperature for compressor operation.

(1) Note: When parameter is set to 1 (= electric back-up), the control system anticipates the back-up starting,depending on the temperature, the volume of the calorifier, the power of the back-up and the parameter setting(= maximum charging time).
