• The unit is a cooling only model • Go to question 2
• Radiant panels • Enter in parameter StC (index 3 menu USER) with the value of 35 °C
• Fan coil units or low temperature
radiators
• Enter in parameter StC (index 3 menu USER) with the value of 45 °C (default value)
• Other applications • Enter in parameter StC (index 3 menu USER) with the value of 55 °C
• Not installed • Go to question 3
• Installed • Enter in parameter PAN (index 9 menu INSTALLER) with the appropriate value:
• Season selection controlled from the unit circuit board
• ON/OFF control from the PR3
• Season selection controlled from the PR3
• ON/OFF control from the unit circuit board
• Season selection controlled from the PR3
• ON/OFF control from the PR3
• Not present • Go to question 5
• Present • Enter in parameter ASA (menu INSTALLER) with the value (1)
• Not present • Go to question 5
• Present • 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
• Not present • No function
• Present • 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 , with the
appropriate value selecting from:
1.
2.
3.
• 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
