17.1.4 AUX Output 1 (AFR)
- 0. None
- 1. Fault alarm: the contact is closed in case of fault
- 2. Humidistat alarm: the output is closed when the AUX 1 is
set as humidistat and it is closed.
- 3. External heat request: the contact is closed to generate an
heat request to a external heat source instead of the heating
resistors.
Turn the knob and select:
17.2 Energy manager
parameter 1
Press the OK button to con rm. Turn the knob and select:
17.2.0 Hydraulic scheme
Hydraulic scheme. De ne the hydraulic con guration corre-
sponding to the installation. Here we got the options:
-None
- Plus (SPLIT M-R; M-RX); only heating/cooling
- Compact (SPLIT M-CR; M-CRX); DHW tank integrated
- Flex (SPLIT M-R; M-RX with separated tank) external DHW tank
- HP Water Heater; only DHW
17.2.1 Thermoregulation
Activate/deactivate the thermoregulation function
17.2.2 ECO / COMFORT
De ne the delay time of the heating resistors switching on
starting from the longer one (ECO PLUS) to the shorter one
(COMFORT PLUS).
17.2.3 FlowT HP O set
De ne the  ow setpoint temperature compensation due
to heat losses along the hydraulic connection between the
outdoor unit and the internal hydraulic module.
17.2.4 Boost Time
Enabled only with thermoregulation active and thermoregu-
lation type set as “Basic Thermoregulation” (see parameters
421/521/621). It de nes the delay time to increment the  ow
setpoint temperature by step of 4°C (max 12°C). If the parame-
ter value is 0 the function is not active.
17.2.6 Active Resistance Stages
De ne the number of active stages of the heating resistors
17.2.9 Antiblocking Function Enable
activate the antiblocking function ofthe main circulator. Main
circulator is switched on and 3way valve is positioned in DHW
mode for 30s after 23h without any activity.
Turn the knob and select:
17.3 Central Heating
Press the OK button.
Turn the knob and select:
17.3.0 CH pump pre-run time
De ne the pre-run time of the main circulator to detect water
 ow in the primary circuit.
17.3.1 Time for pre-run new attempt
De ne the waiting time between a pre-run cycle and the fol-
lowing one.
17.3.2 CH Pump Overrun
Post circulation time.
17.3.7 Max PWM Pump
Circulator max speed
17.3.8 Min PWM Pump
Circulator min speed
17.3.9 Floor drying Flow
Set Point Temperature
De ne the  ow setpoint temperature for the  oor heating. (see
parametre17.8.1).
Push OK button.
Turn the knob and select:
17.4 Cooling
Press the OK button.
Turn the knob and select:
17.4.0 Cooling mode activation
Press the OK button.
Turn the knob and select:
- Not active
- Active (enables the function)
17.4.1 Cooling anticycling time
De ne the delay time for the end of cooling request and heat
pump switching o .
17.4.2 Cooling Flow T HP O set
De ne the  ow setpoint temperature compensation due
to heat losses along the hydraulic connection between the
outdoor unit and the internal hydraulic module.
Push OK button.
Turn the knob and select:
17.5 Domestic Hot Water
Press the OK button. Turn the knob and select:
17.5.2 Comfort function
Con gures the domestic hot water production mode as fol-
lows:
- Disabled
- Time Based (starts the comfort function for periods which can
be set through the domestic water production schedule pro-
gramming feature)
- Always Active
- HC/HP
NOTE: The hot water storage is heated only by the heat pump
when the EDF input is enabled (see par. 17.1.0) and switches
to 230V (reduced rate electricity supply).
- HC/HP 40°C
NOTE: Similar to HC/HP, during full rate electricity supply (EDF
input = 0V) the hot water storage is kept heated to 40°C.
- GREEN
NOTE: uses only the heat pump in the periods con gured
with the domestic water auxiliary schedule programming
function.
17.5.3 Max HP charging time
De ne the charging time of the DHW tank done only with the
heat pump. When this time elapses, the integration resistors
are switched on.
Press the OK button to con rm. Turn the knob and select:
17.5.4 Thermal Cleanse
Function Function
Activating this function, the sanitary water tank is heatted up at
60°C for 1h every 24h .
Press the OK button to con rm. Turn the knob and select:
- ON (enable function)
- OFF
17.5.5 Thermal Cleanse
Function start time
De ne the start time of the thermal cleanse function
Turn the knob and select:
17.6 Manual Mode - 1
Manual activation of the system components (circulators, di-
verter valve, resistors, etc)
17.7 Manual Mode - 2
17.7.1 Force Hp Heat
