1 6  Operating principle

The heat pump transmits the energy contained in the 

surrounding air into the dwelling to be heated.
The heat pump consists of four main elements, in which 

a refrigerant (R410A) circulates.

 

- In  the  evaporator  (ref. 

13

figure  7,  page  10

)  :

 

The energy is taken from the surrounding air and is 

transmitted  to  the  refrigerant.  Because  it  has  a  low 

boiling  point,  it  changes  from  the  liquid  state  to  the 

vapour  state,  even  in  cold  weather  (down  to  -20  °C 

outdoor temperature).

 

- In  the  compressor  (ref. 

10

fig  7  ,  page  10

)  :

 

The  vaporised  refrigerant  brought  to  high  pressure 

and takes on more calories.

 

- In  the  condenser  (ref. 

15

figure  8,  page  10

  )  :

 

The  energy  in  the  refrigerant  is  transmitted  to  the 

heating circuit. The refrigerant returns to liquid state.

 

- In  the  expansion  valve  (ref. 

9

figure  7,  page  10

)  :

 

The liquefied refrigerant is brought back to low pressure 

and returns to its initial temperature and pressure.

The  heat  pump  is  equipped  with  a  controller,  which 

controls  the  room  temperature  based  on  the  outdoor 

temperature  measurement  and  governed  by  the 

temperature control.
The  room  thermostat  (option)  provides  a  corrective 

action for the temperature control.
The hydraulic unit is equipped with an electric back-ups 

system,  which  is  triggered  to  provide  additional  heat 

during the coldest periods.

• 

Regulation functions

 

- The heating circuit’s initial temperature is controlled by 

the temperature control.

 

- The power of the outdoor unit is modulated according 

to  initial  heating  temperature  via  the  “inverter” 

compressor.

 

- Possibility to set the setpoint of maximun heating initial 

temperature.

 

- Control of the electric back-up heating.

 

- The  daily  timer  program  enables  you  to  define 

the  periods  for  comfortable  or  reduced  ambient 

temperature.

 

- Summer/winter mode switchover is automatic.

 

- Control of the supplementary boiler* (the electric back-

ups are deactivated).

 

- The  room  thermostat*  (option)  provides  a  corrective 

action for the temperature control

 

- Control of a second heating circuit*.

 

- Domestic hot water : Heating time programme, control 

of the operation of the DHW circulation pump*.

 

- Control of swimming pool heating*.

 

- Managing the cooling*.

• 

Protection functions

 

- Anti-legionella cycle for domestic hot water. 

If the heat pump is equipped with optional equipment and 

the associated kits.

• Domestic hot water (DHW) operating principle

Two  domestic  hot  water  (DHW)  temperatures  can  be 

parametered: comfort temperature (line 1610 to 50 °C) 

and reduced temperature (line 1612 to 25 °C).
The default heat pump program (line 560, 561 and 562) 

is set for comfort temperature from 0.00 to 5.00h and for 

reduced temperature for the rest of the day.
This  optimises  electrical  consumption  while  ensuring 

comfortable availability of hot water.
Setting for reduced temperature can be useful to prevent 

the DHW from switching on too often and for too long 

during the day.
The production of domestic hot water (DHW) is triggered 

when the temperature in the tank falls 7°C (setting from 

line 5024) below the set temperature.
The heat pump produces the domestic hot water, which 

is then supplemented, if required, by electrical backup 

heating  from the tank.
To  ensure  a  DHW  setting  over  45°C,  the  electrical 

backup heating or the boiler must be left on.
Depending on how the parameter (1620) is set, comfort 

temperature can be reached 24h/day or only at night or 

depending on the heat pump programme.
If  the  contract  concluded  with  the  energy  provider 

includes a subscription to day/night tariff, the electrical 

backup is subordinate to the supplier’s power tariff and 

the comfort temperature may only be reached at night.
If  no  particular  contract  is  concluded,  the  comfort 

temperature  can  be  reached  at  any  time,  including 

during the day
The  production  of  DHW  takes  priority  over  heating; 

nevertheless  the  production  of  DHW  is  controlled  by 

cycles  that  control  the  times  assigned  to  the  heating 

and the production of DHW in the event of simultaneous 

demand.
A  function  to  switch  from  "reduced"  to  "comfort"  is 

provided on the front of the user interface (see ref. 

1

figure 39, page 29

 ).

If  the  heating  installation  is  equipped  with  a  DHW 

circulation  pump,  the  pump’s  operation  during  DHW 

cycles can be parametered.
Anti-legionella cycles can be programmed.

• Fan convectors with integrated control system

Do not use a room sensor in the area.
