Special parameters
1. Used to adjust the target temperature difference between the production circuit
outlet and inlet in heating mode.
2. Used to adjust a temperature difference between the calculated target outlet
temperature and the actual outlet temperature of the heating pump. This option is
useful in cases where collection must be performed at a different temperature than
consumption, or when an intermediate exchanger is installed between production and
use.
3. Used to enable simultaneous activation of units that request heating and cooling.
A.
ENABLED: In case of simultaneous heating and cooling requests, all outlet units are
enabled equally.
B. DISABLED: In case of simultaneous heating and cooling requests, priority is given
to the service (heating / cooling) of the lowest number outlet group with an
enabled request. Activation of units that do not request the service set as a priority
is not allowed. This restriction only affects the outlet units that are enabled for
both heating and cooling mode.
Note: Simultaneous unit activation is associated with the heating and cooling services. If it
is modified for the heating service, it will automatically change for cooling.
Heating buffer
1. Allows adjust the maximum settable heating buffer setpoint. This is the setpoint in
case of surplus for the SG states.
2.5. Configuration of the cooling system
Active cooling
1. Used to enable the active cooling service.
2. Used to select the type of connection to the active cooling emission system.
A.
DIRECT: Cooling production is enabled by requests coming from indoor terminals.
Enabling the outlet units for active cooling is not allowed when another service is
being produced (heating / DHW / pool).
B. BUFFER: Active cooling production is enabled by the temperature probe of the
buffer storage tank. Enabling the outlet units for active cooling is allowed when
another service is being produced (heating / DHW / pool).
3. Used to enable use of the production pump for the active cooling service.
Passive cooling
1. Used to enable the passive cooling service.
2. Used to enable use of the circulator pump for the passive cooling service.
Used to enable use of the collector circulator pump for the passive cooling service.
Note: The passive cooling system is enabled by requests coming from indoor terminals,
even in installations with a cooling buffer storage tank.
