Z-450
Setting Up
1. Once the Z-450 has been installed in its place of operation, wait approximately 24 hours
before switching it on. This will allow the oil in the compressor to settle and prevent
contamination of the refrigerant fluid.
2. Connect the machine to the power supply.
3. Switch it on. The machine will then commence operations to reach its default working
temperature of 16ºC. The ventilation system will start up and run constantly, alternating
between refrigeration and heating cycles.
Viewing and Changing the Working Temperature.
The Z-450's built-in digital regulator allows you to view the current temperature and modify the
assigned temperature.
Once the machine is switched on, the regulator takes temperature measurements using the
internal thermometer and displays these continuously on the screen.
The machine is programmed and calibrated at the factory to operate at a default temperature of
16ºC. However, if you wish to assign a different temperature, follow the steps below:
1. Press and release the key 'SET'. The screen will show SP alternating the set point value.
2. Use the arrow keys to adjust the value.
3. Press and release 'SET' to confirm the value. The value will save in the memory of the
device and the screen will show the current value of the temperature.
Once you have assigned the new temperature, the thermostat will begin to adjust the heating and
cooling cycles as required. You can consult the status of the machine (i.e. whether it is heating,
cooling or in neutral mode) by checking the corresponding LED indicators displayed on the left
side of the thermostat screen. The indicator for the cooling cycle is the snowflake and for the
heating cycle is the sun indicator.
