First installation
At first installation, it's necessary the following:
1. Select the kind of gas.
2. Set the range of the pressure probes.
In the following paragraph a short cut for the above operations.
Chapters 10 Parameters programming and 16 will show in detail these operations.
• How to set the kind of gas
The controller has memorized the relation between temperature and pressure for some gases.
The pre-set gas is: R404.
If another gas is used, act as in the following:
1. Enter the Programming mode by pressing the Set and DOWN key for 3s.
2. Select the "Pr2" parameter. Then enter the password 3 2 1 0.
3. Select the FtyP, kind of gas, parameter.
4. Press the "SET" key: the value of the parameter will start blinking.
5. Use "UP" or "DOWN" to change the gas among the following: r22= R22; r404=R404A; 507=R507; 134=134; r717= ammonia.
6. Press "SET" to store the new value and move to the following parameter.
To exit: Press SET + UP or wait 30s without pressing a key.
NOTE: the set value is stored even when the procedure is exited by waiting the time-out to expire.
