Atlantic Alfea Evolution 5 - Configuration 1 or 3; Parametering the Setting; Hydraulic Connections; Special Cases

4.1 Conguration 1 or 3 :
" Parameter 90.
Conguration 1 : 1 heating circuit with or without electrical back-up (see page 40);
and : 1 heating circuit with or without electrical back-up, with DHW tank (voir schéma page 41).
Conguration 3 : Boiler connection, 1 heating circuit (see "boiler connection kit" manual);
and : Boiler connection, 1 heating circuit with DHW tank (see "boiler connection kit" manual).
- Additional electrical heating can only be managed with
the heat pump electrical back-ups kit.
- DHW tank control (with electrical back-up) requires
the use of the DHW kit.
- The management of a boiler is required to install a
boiler connection kit.
4.1.1 Hydraulic connections
" if boiler connection
• Removing the boiler’s circulation pump.
• For boilers where the heating system’s circulation
pump has not been removed, a disconnection bottle
must be installed.
• Install the elements from the boiler connection kit.
" In the case of a mixed DHW tank
• Install the distribution valve on the heating circuit.
4.1.2 Electrical connections
• 1 - Power supply to outdoor unit.
Please refer to section "Electrical connections on the
outdoor unit side".
• 2 - Interconnection between the outdoor unit and the
hydraulic unit.
• 3 - Outdoor sensor.
• 4 - Room thermostat and/or room control unit (option).
• 5 - Contract with the power provider. Connect the
"Power Provider" contact to input EX2.
" if electric back-ups
See the user instructions provided with the electrical
back-ups kit.
• 6 - Power supply to the electrical back-ups :
Connect the power supply of the heat pump’s electrical
back-ups to the mains supply board.
" In the case of a mixed DHW tank
Please refer to the instructions supplied with the DHW kit.
• 7 - Connect the distribution valve.
• 8 - Connect the DHW sensor to the heat pump’s
regulator board.
• 9 - Connect the back-up resistance.
• 10 - Connect the power supply of the DHW heating
back-up to the mains supply board.
" if boiler connection
Please refer to the instructions supplied with the boiler
connection kit.
• 15 - Distribution valve (deviation boiler).
• 16 - Boiler supply (or if used with room thermostat,
connect a relay for control boiler).
• 17 - Move the low-temperature sensor to the low-
temperature point on the boiler connection.
" In the case of a heated oor
Heated oor thermal safety fuse.
• 20 - The installer is responsible for connecting the
heated oor’s safety system. Thermal safety will stop
the heat pump if the temperature in the oor is too high.
4.1.3 Parametering the setting
• Adjust the conguration: 1 or 3 (line 90).
• Adjust the DHW programme (lines 82-83-84 & 85).
• Adjust the heating curve slope (line 66).
4.1.4 Special cases
Please consult us regarding any other installation
