In OTHER HEATING SOURCE the following
parameters should be set. Backup electric heater
is optional.
ddTT11__IIBBHH__O
ONN sets the temperature difference
between the heat pump
’
s leaving water set
temperature (T1S) and the heat pump
’
s leaving
water temperature (T1) above which the backup
electric heater heating element are on.
When T1S - T1
≥
dT1_IBH_ON the backup
electric heater is on (on models where the
backup electric heater has a simple on/off
control function).
tt__IIBBHH__DDEELLAAYY sets the delay between the
compressor starting and the backup electric
heater being turned on.
TT44__IIBBHH__O
ONN sets the outside temperature below
which the backup electric heater is used. If the
outside temperature is above T4_IBH_ON, the
backup electric heater is not used.
The relationship between operation of the backup
heater and the outside is shown in figure
T4: outside temperature
IBH: Backup electric heater
Currently for unit the IBH is not avaible.
ddTT11__AASSHH__O
ONN sets the temperature difference
between the heat pump
’
s leaving water set
temperature (T1S) and the heat pump
’
s leaving
water temperature (T1) above which the
additional heating source is on. When T1S - T1
≥
dT1_AHS_ON the additional heating source is on.
tt__AASSHH__DDEELLAAYY sets the delay between the
compressor starting and the additional heating
source being turned on.
TT44__AAHHSS__O
ONN sets the outside temperature below
which the additional heating source is used. If
the outside temperature is above T4_ASH_ON,
the additional heating source is not used.
The relationship between operation of the
additional heating source and the outside
temperature is shown in the picture below.
AHS: Additional heating source
T4: outside temperature
IIBBHH PPO
OSSIITT..:: defines the position of the IBH (only
possible selection)
PP__IIBBHH11:: set the electrical power of the IBH (if
present).
It is used for more accurate calculation of the
unit's output and efficiency.
P_IBH2: set the electrical power of IBH 2 (if
present).
It is used for more accurate calculation of the
unit's output and efficiency.
Not available for the SPHERA EVO 2.0 unit
PP__TTBBHH: set the electrical power of the TBH (if
present).
It is used for more accurate calculation of the
unit's output and efficiency.

The HOLIDAY AWAY SETTING menu settings are
used to set the outlet water temperature to
prevent water pipes freezing when away from
home in cold weather seasons.
In HOLIDAY AWAY SETTING the following
parameters should be set.

’
s leaving water
set temperature for space heating mode when in
holiday away mode.
TT55SS__HH..M
M__DDHHW
W sets the heat pump

EEnnSSW
WIITTCCHHPPDDCC: Enables or disables the € switch
function.
The € switch function makes it possible to
calculate the resource (between the heat pump
and/or boiler) that is able to fulfil the heat
demand with the lowest economic cost in every
operating condition.
To use the € switch function, simply enter the
cost of a cubic metre of gas (GAS_COST) and
the cost of a kWh of electricity (ELE_COST), both
of which can be obtained from the energy
company's supply contract.
The function calculates the minimum efficiency of
the heat pump required to make it more cost-
effective than the boiler.
When the efficiency of the heat pump is lower
than the minimum efficiency, the heat pump is
switched off and the demands are handled by
the boiler.
If the € switch function is activated, the boiler
activation logic for integration remains
unchanged.
GGAASS__CCO
OSSTT:: set the average cost of fuel gas
used to power the boiler (in €/mc).
If you don't know this value and want to
calculate it, we recommend that you take your
latest gas bills, add up the various amounts (in
€) and divide it by the sum of the amount of
gas consumed (in mc).
EELLEE__CCO
OSSTT:: set the average cost of electricity (in
€/kWh)
M
MAAXX__SSEETTHHEEAATTEERR:: maximum setpoint value that
can be reached by the boiler for setpoint control
by 0-10V signal.
For a Rinnai boiler the value is 80°C
M
MIINN__SSEETTHHEEAATTEERR:: minimum setpoint value that can
be reached by the boiler for setpoint control by
0-10V signal.
For a Rinnai boiler the value is 30°C
M
MAAXX__SSIIGGHHEEAATTEERR:: 0-10V signal relating to the
maximum boiler setpoint value
For a Rinnai boiler the value is 10V
M
MIINN__SSIIGGHHEEAATTEERR: 0-10V signal relating to the
minimum boiler setpoint value
For a Rinnai boiler the value is 3V
DDEELLTTAATTSSO
OLL:: set the temperature difference
between Tsol (if solar option is present) and T5
which activates the pump for the solar option
(Pump_S).
When Tsol - T5 > DELTATSOL the Pump_S is
activated.
