WHAT TO DO
• Go to question 2
• Enter in parameter StC (index 3 menu USER) with the value of 35 °C
• Enter in parameter StC (index 3 menu USER) with the value of 45 °C (default value)
• Enter in parameter StC (index 3 menu USER) with the value of 55 °C
• Go to question 3
• Enter in parameter PAN (index 9 menu INSTALLER) with the appropriate value:
Value (1):
• Season selection controlled from the chiller circuit board
• ON/OFF control from the PR3
Value (2):
• Season selection controlled from the PR3
• ON/OFF control from the chiller circuit board
Value (3):
• Season selection controlled from the PR3
• ON/OFF control from the PR3
• Go to question 5
• Enter in parameter ASA (menu INSTALLER) with the value (1)
• Go to question 5
• Enter in parameter AAS (index C menu INSTALLER) with the appropriate value (in seconds):
this parameter shows the reversing time for the three way diverting valve in the circuit for the
production of domestic hot water
• No function
• This parameter enables a digital contact ID (shown on the electrical schematic with the
reference TRA) onto which to connect an ambient thermostat with which to disable the
compressors and electric heaters. Enter in parameter trA (index D menu INSTALLER), with the
appropriate value selecting from:
1. Value (1 or 2): ENABLED
2. Value (0 or 3): DISABLED
3. It is reminded that the OPEN state of the contact represents:
• stops compressors and heaters if the parameter value is set to 1
• stops compressors, pump and heaters if the parameter value is set to 2
• pump alarm (as in the previous software version), if the parameter value is set to 3
