4.1 Configuration 1, 2, 3 or 4:
heat pumps with electric back-ups
"
Parameter 5700.
Configuration 1
: 1 heating circuit (see figure
page 45
).
Configuration 2
: 1 heating circuit and DHW tank. (see figure
page 46
).
Configuration 3
: 2 heating circuits (see figure
page 47
).
Configuration 4
: 2 heating circuits and DHW tank. (see figure
page 48
).
DHW tank control (with electrical back-up) requires the
use of the DHW kit.
The control of 2 heating circuits requires the installation
of the 2
nd
circuit.
4.1.1 Hydraulic connections
"
In the case of a mixed DHW tank.
Install the directional valve on the heating circuit
(on circuit 2 if it exists).
"
In the case of 2 heating circuits.
With the 2
nd
circuit kit, the hydraulic unit's circulation
pump (CC1) must be moved and installed in a box of
the 2
nd
circuit kit (CC1).
4.1.2 Electrical connections
• 1
- Power supply to the outdoor unit.
Please refer to section (Electrical connections on the
outdoor unit side
page 24
).
• 2
- Interconnection between the outdoor unit and the
hydraulic unit (see
figure 37 , page 26
).
• 3
- Power supply to the electrical back-ups :
-Connect the electrical supply for the back-ups
(terminals 20, 21, 22 and 23) to the electrical panel.
(see
figure 37, page 26
).
• 4
- Outdoor sensor (see
figure 38, page 27
).
• 5
- Room thermostat and/or room control unit (Option,
see
figure 38, page 27
).
• 6
- Contract with the power provider :
-Connect the "Power Provider" contact to input EX5 or
EX4. (see
figure 38, page 27
)
"
In the case of a mixed DHW tank.
Please refer to the instructions supplied with the DHW
kit.
• 7
- Connect the directional valve to connector QX4,
(see
figure 38, page 27
).
• 8
- Connect the domestic water sensor to terminal
BX1 on the heat pump’s control panel (see
figure 38,
page 27
).
• 9
- Connect the back-up resistance to terminal 19
(Earth) and relay RP EPS to terminals 2 (L) and 4 (N)
(see
figure 37, page 26
).
• 10
- Connect the electrical power supply for the
domestic water back-up (terminals 17, 18 and 19) to
the electric panel (see
figure 37, page 26
).
"
In the case of 2 heating circuits.
Please refer to the instructions supplied with the second
circuit kit.
• 11
- Circulation pump CC2.
• 12
- Circulation pump CC1.
• 13
- Mixer valve.
• 14
- Initial sensor.
• ()
- Interconnection between RVS / AVS.
"
In the case of a heated floor.
Heated floor thermal safety fuse.
• 20
- The installer is responsible for connecting the
heated floor’s safety system. Thermal safety will stop
the heat pump if the temperature in the floor is too high.
