The menus are briefly described below:
• The “Unit Menu” displays information such as temperature, pressure and circuit states.
• The “Setpoint menu” is used to set the setpoints for the various available functions. Different
setpoints can be set depending on the available operating modes (chiller, heat pump and
recovery). Dual setpoint values can also be set for chiller and heat pump operation (only if the
digital input is fitted and the “dual setpoint” function is enabled in the “user menu”).
• The “I/O menu” shows the status of the digital inputs and values read from the analogue inputs.
It also shows the status of the digital outputs and the voltage supplied to the analogue outputs.
If expansions are necessary (depending on the configuration parameters), the inputs and outputs
of the latter are also shown.
• Parameters relative to user programming of the unit can be displayed and set in the “User
menu”.
• Unit configuration parameters can be displayed and set in the “manufacturer menu”.
• Service engineers can view and set parameters in the “Assistance menu”.
• The list of alarm events recorded by the unit can be displayed in the “Log menu” (only accessible
if the clock card is installed).
• The “Clock menu”, if the clock board is present, is used to set and display the date and time and
configure the time bands (except for W3000 base).
After enabling time bands from the “enable time bands” parameter in the “user menu”, time
bands can be set and specific operating modes and different setpoints can be set according to
requirements.
Several time bands (up to 10) of different types (A, B, C and D) can be set during the day.
Figure 1.3 shows an example: the beginning of the first time band is set at 00:00 and the end of
the tenth time band is set at 23:59; the end of one time band determines the beginning of the
following one.
To use a smaller number of bands, set the time a band ends to the same time it begins, and that
band will be ignored. Summer and winter setpoints and unit On/Off switching can be set for each
time band. If the unit is switched Off, it will remain in the “Off from time bands” mode.
