Pompe di calore inverter aria/acqua con ventilatori assiali
- continuous operation (default);
The circulator is switched off immediately if:
-There is a manual reset pump block alarm, including the flow switch alarm;
-With remote input in standby or off, the pump (if running) is always switched off with a delay equal to
P02
in tenths of a minute (default P02=2)
The circulator can be configured with
P03
to operate independently from the compressor or on call.
0=continuous operation in heating/cooling mode(default P03=0)
1=operating on call by temperature controller
Note
: with automatic reset flow switch alarm triggered, the circulator is on even if the compressor is off. The circulator is always on when the
antifreeze heaters are running and if operation of the hydraulic pump in antifreeze is enabled. Antifreeze operation is enabled if the regulation
temperature drops below
P04
°C (default 5°C), and disables if the regulation temperature rises above
P04+P05
°C (Default value
P05
=2,0°C).
7.1 CONTINUOUS OPERATION [P03=0] - Default
The circulator is only off with the unit OFF, in all other cases it is always on.
7.2 OPERATION ON CALL BY TEMPERATURE CONTROLLER [P03=1]
In this operating mode, the circulator is active on demand by the temperature controller, after a delay time of
P01
seconds (default
P01=30
) from
when the pump switched on, the compressor switches on as well.
Whereas when switching off, the pump is deactivated after a delay time of
P02
minutes (default P02=2) from when the compressor switches off.
With automatic reset flow switch alarm triggered, the circulator is on even if the compressor is off.

OPERATING ON CALL BY TEMPERATURE CONTROLLER WITH PERIODIC ACTIVATION
The function is disabled if
P17=0
(default).
If
P03=1
, the circulator turns on periodically for a time defined by the parameter
P17
(in seconds) after a count, lasting a time set by parameter
P16
(in minutes), activated when the pump switches off because temperature control fulfilled.
With automatic reset flow switch alarm triggered, the pump is on even if the compressor is off.
The periodical function is a suspended if the antifreeze protection trips.

OPERATION WITH HEATER ACTIVE
See paragraph 10.8.
7.5
PROPORTIONAL REGULATION OF THE CIRCULATOR
The speed of the circulator changes depending on the temperature difference between the inlet water and outlet water of the heat exchanger,
according to the diagram below, where:
•
P07
: Maximum speed = 100%
•
P08
: Minimum speed = (according to model)
•
P09
: modulating pump inlet/outlet water Delta T setting (°C) (according to model)
•
P10
: Modulating pump Delta = 3°C (default)
