12
ENGLISH
EN
The HSM operates as soon as power is supplied, the
key of the user interface has no effect.
The outside air temperature value is required for correct
operation of the HSM. It can be acquired in two different
ways (depending on the configuration):
• Measured by a thermistor connected to the HSM control
• Read on the heat pump control via the CCN bus.
The summer mode is automatically activated, based on the
outside air temperature. The summer mode is activated, if
the outside air temperature rises above ’oat_hl1’ for a
configurable period (‘stop_tmr’ parameter of the HL1_CONF
menu, default value 120 minutes i.e. two hours).
The summer mode is deactivated, if the outside air tempe-
rature sinks below ‘hl1_oat’ – 2K for a configurable period
(‘starttmr’ parameter of the HL1_CONF menu, default value
300 minutes i.e. five hours).
The outside air temperature threshold ‘hl1_oat’ is entered
in the SETPOINT menu. If the outside air temperature is
not available or missing, the summer mode is forced to NO.
The heat pump is controlled by the HSM via the CCN bus.
For this the CCN operating mode must be selected in the
heat pump control.
The HSM writes the heat pump setpoint and controls the
start-up and stop, based on the heating load and the domestic
hot water production load.
6.4.1 - Control point
The heat pump control point can take the following values
based on the different requirements:
• CTRL_PNT = heating setpoint + offset based on the
outside air temperature
• CTRL_PNT = domestic hot water setpoint
• CTRL_PNT = anti-legionella mode setpoint
An offset can be added to the control point (see ‘hp_bias’
parameter in the GEN_CONF menu).
If the external pump has been configured, it starts as confi-
gured ("hppmpsby" parameter in the PUMPCONF menu):
• hppmpsby = no:
the pump runs if the heat pump is in the "On" mode.
• hppmpsby = yes:
The pump runs only if the compressor runs. If the
compressor has stopped, the pump will be activated for
one minute every five minutes to take an entering water
temperature (EWT) sample.
6.5.1 - Anti-stick function
If the "hppmp_s" parameter in the PUMPCONF menu
has been configured as "yes", the water pump is started for
five seconds every Monday at 12.00 hours.
6.5.2 - Frost protection
If the outside air temperature falls below the frost protec-
tion threshold (see SETPOINT menu), the pump is forced.
This frost protection stops if the outside air temperature
again rises above the frost protection threshold + 1K.
6.6.1 - Pump P1
Water pump P1 is started, if the summer mode is deactivated.
6.6.2 - Anti-stick function
If the "hl1pmp_s" parameter in the PUMPCONF menu
has been configured as "yes", pump P1 is started for five
seconds every Monday at 12.01 hours.
6.6.3 - Heating setpoint
The heating setpoint transmitted to the heat pump can be
determined in two ways:
• If ‘oat_ctrl’ = NO: the heating setpoint is the same as
the setpoint of loop 1 ‘hl1_stp’ in the SETPOINTS
menu.
• If ‘oat_ctrl’ = YES: the heating setpoint is based on
the outside air temperature.
6.6.4 - Summer mode
In summer mode heating of water loop 1 is deactivated.
Pump P1 is stopped.
6.7.1 - Pump P4
Water pump P4 of the second heating loop is started at the
same time as pump P1 of water loop 1.
6.7.2 - Anti-stick function
If ‘hl2pmp_s’ parameter in the PUMPCONF menu has
been configured as "yes", pump P4 is started for five
seconds every Monday at 12.01 hours.
6.7.3 - Heating setpoint
The heating setpoint transmitted to the heat pump can be
determined in two ways:
• If ‘oat_ctrl’ = NO: the heating setpoint is the same as
the setpoint of loop 1 ‘hl2_stp’ in the SETPOINTS
menu.
• If ‘oat_ctrl’ = YES: the heating setpoint is based on
the outside air temperature.
6.7.4 - Control of mixing valve SV34
Mixing valve SV34 is controlled within 0-10 V by a PID to
control temperature HL2_WT of loop 2 in proportion to
the previously determined setpoint.
6.7.5 - Summer mode
In summer mode heating of water loop 2 is deactivated.
Pump P4 is stopped and mixing valve SV34 is fully closed.
13
ENGLISH
EN
6.8.1 - DHW setpoint
The domestic hot water setpoint is determined in the
SETPOINTS menu - the default is 55°C. This setpoint is
transmitted to the heat pump, when the HSM changes in
the domestic hot water production mode.
6.8.2 - Priority
Priority is given to the domestic hot water production.
However, to avoid a temperature drift in the heating loops
it is designed to regularly change from the DHW mode to
the heating mode (see the following chapter).
6.8.3 - Domestic hot water production time/stop time
If the HSM changes to the domestic hot water production
mode, it must remain there for a time "dhw_dur" defined
in the DHW_CONF menu. At the end of this time, the
HSM is allowed to return to the heating mode, if required.
In the same way, if the HSM changes to the heating mode,
it remains there for a time "dhw_stop". This time prevents
a temperature drift in the heating loops.
6.8.4 - Anti-legionella mode
The anti-legionella function permits heating of tank and
piping to eliminate the risk of legionnaires' disease.
The day, time and duration of the anti-legionella mode
operation are configurable in the GEN_CONF menu.
The anti-legionella mode setpoint is determined in the
SETPOINTS menu - the default value is 65°C. This setpoint
is transmitted to the heat pump when the HSM changes to
the domestic hot water production mode.
If a pre-heating pump is installed, this is controlled in the
anti-legionella mode.
A second domestic hot water tank can be installed.
6.9.1 - Additional pump P7
Pump P7 is started if the temperature of additional tank
GT7 falls below the DHW setpoint minus hysteresis. It is
stopped when the temperature again rises above temperature
GT7 minus 2 K and is under the DHW setpoint.
6.9.2 - DHW back-up pump P7-2
Pump P7-2 is started when the ‘Back-up heating allowed’
information is activated and when temperature GT7 minus
2 K is below the DHW setpoint threshold minus 5 K (see
chapter "Back-up heating"). This pump is stopped if the
information returns to zero or if GT7 minus 2 K again rises
above the DHW setpoint.
6.9.3 - Anti-sticking
If parameter ‘dhwpmp_s’ of the PUMPCONF menu is
configured to ‘YES’, additional pump P7 is started for five
seconds every Monday at 12.03 hours and back-up heater
pump P7 minus 2 K is started every Monday at 12.04 hours.
If a three-way domestic hot water distribution valve is
installed, this mixing valve SV35 is controlled within 0-10 V
by a PID so that the hot water distribution temperature
GT5 is controlled around the DHW setpoint.
If a domestic hot water pre-heating pump is installed, this
pump P5 is started when the distribution temperature GT5
is below the DHW setpoint minus 10 K. It stops when this
temperature again rises to the DHW setpoint minus 5 K.
This function permits instant hot water at the tap, even if
the domestic hot water distribution system is very long.
6.11.1 - Anti-sticking
If the "dhwpmp_s" parameter of the PUMPCONF menu
is configured to "YES", pump P5 is started every Monday
at 12.05 hours.
6.12.1 - Heating time delay
The "bck_pull" parameter in the BCKUPCONF menu,
that is configured by the user, shows the time delay before
the start-up of the back-up heater.
This function permits the heat pump to reheat the water
circuits using thermodynamic heating before starting the
back-up heating (often increased energy consumption).
This time delay is not initialised when an alarm is cancelled.
6.12.2 - "Back-up heating authorised" information
Operation of the back-up heating is authorised, if the heat
pump is at maximum capacity and the heating time delay
has expired.
6.12.3 - Back-up heating with electric heating stages
As an option, the HSM can control up to four electric heating
stages, used as back-up heating.
If the second domestic hot water tank is installed, the
temperature of loop 1 is controlled by electric heating stages, if
the ‘Back-up heating authorised’ information is activated.
Each electric heating stage is now started successively,
based on the heating load.
If the second domestic hot water tank is installed, two PI
control loops are used:
• The first PI controller regulates mixing valve SV31 to
control the temperature of loop 1.
• The second controller regulates the temperature of
the DHW back-up loop.
If the ‘Back-up heating authorised’ information is activated,
the controller with the largest output is used to control the
electric heating stages successively.
In summer mode, only the electric heating stages are
controlled by the second PI controller, when mixing valve
SV31 remains closed.

ENGLISH
EN
6.12.4 - Back-up heating using an electric boiler
The boiler is started based on the ‘Back-up heating autho-
rised’ information and controlled by a 0-10 V signal to
satisfy the temperature of loop 1, or the temperature of the
DHW tank if domestic hot water is needed.
6.12.5 - Back-up heating using a gas or oil-fired boiler
The boiler is started by the ‘Back-up heating authorised’
information. Mixing valve SV31 is controlled by a 0-10 V
signal to satisfy the temperature of loop 1, or the temperature
of the DHW tank if domestic hot water is needed.
The back-up heating is provided by district heating. Two
heat exchangers are installed, the first for heating and the
second for domestic hot water.
6.13.1 - Heat exchanger for loops 1 and 2
If the ‘Back-up heating authorised’ information is activated
(see chapter "Back-up heating"), temperature GT1 :3 is
controlled by valve SV21 via a 0-10 V signal to satisfy the
setpoint of loop 1 + an offset "d_hl_off".
A PI control loop is configured, and the proportional and
integral gains are adjustable in the DIS_CONF menu.
Valve SV31 is fully closed if back-up valve SV31 is closed
or if the "Back-up heating authorised" information is not
active.
6.13.2 - DHW heat exchanger
If the ‘Back-up heating authorised’ information is activated
(see chapter "Back-up heating"), temperature GT7 :2 is
controlled by valve SV27 via a 0-10 V signal to satisfy the
DHW setpoint.
A PI control loop is configured, and the proportional and
integral gains are adjustable in the DIS_CONF menu.
Valve SV37 is fully closed if the "Back-up heating authorised"
information is not active.
6.13.3 - Back-up valve
If the ‘Back-up heating authorised’ information is activated
and the district heating heat exchanger entering water
temperature is below the mixing bottle temperature (GT1 :4
< GT1 :2), back-up valve SV31 is limited to 95% opening.
The Pro-Dialog+ control system has many fault tracing aid
functions. The local interface and its various menus give
access to all unit operating conditions. If an operating fault
is detected, an alarm is activated and an alarm code is
stored in the ALARMS menu, sub-menu ALARMRST.
The alarm LED on the interface (see chapter 4.1) allows
immediate display of the unit status.
• A flashing LED shows that the circuit is operating but
there is an alert.
• A steady LED shows that the unit or one circuit has
been shut down due to a fault.
The ALARMRST menu on the interface displays up to
five fault codes that are active on the unit.
When the cause of the alarm has been corrected the alarm
can be reset, depending on the type, either automatically
on return to normal, or manually when action has been
taken on the unit. Alarms can be reset even if the unit is
running. This means that an alarm can be reset without
stopping the machine. In the event of a power supply
interrupt, the unit restarts automatically without the need
for an external command.
However, any faults active when the supply is interrupted
are saved and may in certain cases prevent a circuit or a
unit from restarting.
A manual reset must be run from the main interface via
the ALARMRST menu, item RST_ALM. Depending on
the configuration in the GENCONF menu, access to the
item may be protected by a password.

Caractéristiques électriques et conditions de fonctionnement
• L’équipement n’a qu’un seul point de raccordement
électrique localisé en amont immédiat du disjoncteur
principal (alimentation 230 V – 50 Hz sur bornier).
• Tous les raccordements au réseau et les installations
électriques doivent être en conformité avec les
directives applicables au lieu d’installation.
• Les conditions de fonctionnement sont :
- installation à l’intérieur des locaux.
- gamme de température ambiante: de +5°C pour
la température minimum, jusqu’à +40°C.
- altitude inférieure ou égale à 2000 m.
- présence d’eau: possibilité de chutes de gouttelettes.
- présence de corps solides: présence de poussières
non significatives.
- présence de substances corrosives et polluantes :
négligeable.
• Protection des conducteurs d’alimentation : elle n’est
pas assurée par l’équipement.
• Protection IP : L’enveloppe répond à la classification IP23.
• Le HSM est piloté par une régulation type Pro-Dialog+.
Les abréviations suivantes sont fréquemment utilisées:
Le coffret électrique contient en standard:
• un disjoncteur général.
• les équipements de démarrage et de protection des
moteurs.
• les équipements de protection contre les court-circuits.
• Le transformateur d’alimentation du circuit contrôle.
• les cartes électroniques de régulation
Les organes de régulations (sondes, pompes et vannes) ne
sont pas incluent dans la fourniture.
Le système de régulation est composé d’une carte de Type
NRCP2-BASE, d’une carte PD-Aux (gérant une boucle d’eau,
la production d’eau chaude et le chauffage de secours),
d’une carte AUX1 (assurant la gestion d’une seconde
boucle d’eau), d’une deuxième carte AUX1 (contrôlant le
chauffage urbain) et d’une interface utilisateur.
L’ensemble des cartes communique par l’intermédiaire
d’un bus interne, appelé bus LEN. La carte NRCP2-BASE
contient l’ensemble du programme de régulation de la
machine, et gère en permanence la récupération des valeurs
des différents capteurs de température.
L’interface utilisateur dispose d’un afficheur alphanumé-
rique de huit lignes, de deux LED, de cinq touches de
navigation et d'une molette de réglage du contraste.
Toutes les cartes sont alimentées à l’aide d’une source
24 V a.c. référencée à la terre.
En cas de coupure d’alimentation du HSM, celui-ci
redémarre automatiquement sans intervention extérieure.
ATTENTION: respecter les polarités lors de la connexion
des alimentations des cartes afin de ne pas les
endommager.
Toutes les cartes testent en permanence le bon
fonctionnement de leurs circuits électroniques. Une LED
est allumée sur chaque carte pour indiquer son bon
fonctionnement.
1. La LED rouge clignotant avec une période de 2
secondes, une seconde allumée, une seconde éteinte,
indique son bon fonctionnement. Un clignotement
différent signale un dysfonctionnement de la carte ou
du logiciel.
2. Sur l’ensemble des cartes, la LED verte clignote
constamment sur l’ensemble des cartes pour indiquer
que la carte communique correctement sur son bus
interne. L’absence de clignotement de la LED, indique
un problème d’installation du bus LEN.
3. La LED orange de la carte NRCP2-BASE clignote
lors de toute communication sur le bus CCN.
Les sondes de température d’eau devront être installées
sur les différentes boucles d’eau ou dans le ballon d’eau
chaude sanitaire. La sonde OAT sera montée à l’extérieur,
si possible à l’ombre.
