SETTINGS AND CONTROLS
A.
CHECKING THE FLOW THROUGH THE BY-PASS:
Please note:
The heat pump only operates while the filtration is running. The length of the daily filtration cycles may be
insufficient for the heat pump to properly maintain the pool water temperature around the set point. In this
case, lengthen the filtration cycles and cover the pool while it is not in use to limit heat loss from the pool.
In "COMFORT" mode the machine will operate at maximum power until the set point temperature is
reached. In "ECO" mode the machine will adjust the power according to the water and air
temperature in order to optimize electricity consumption.
The amount by which the pool water temperature is raised by passing through the titanium
heat exchanger depends on two factors:
o
flow rate (adjustable)
o
the temperature difference between the incoming heat transfer fluid and the incoming pool water.
The higher the ambient temperature, the greater the heat transferred to the fluid at the inlet of the
heat exchanger.
The temperature difference between the inlet and outlet of the heat pump varies depending
on the operating conditions of the machine:
o
diminuirà con la diminuzione della temperatura dell'aria ambiente e / o aumenterà la
temperatura dell’acqua da piscina
o
aumenterà con l'aumentare della temperatura dell'aria ambiente e / o diminuirà la
temperatura dell’acqua da piscina
.
To regulate the flow rate of the by-pass loop, the machine must be operating at full power,
i.e. the set point temperature is more than 3°C above the pool water temperature for at least
20 minutes. Under these conditions, and only under these conditions, the by-pass must be
adjusted to obtain a delta T of 3°C.
Please note:
The efficiency of heat transfer between the heat transfer fluid and the pool water will decrease if the heat
exchanger is encrusted (scale, etc.) or partially clogged. This can prevent the pool water from reaching
the set point even with the bypass valves configured to minimise the flow rate through the bypass loop..

INITIAL HEATING-START-UP PHASE
The first time the heat pump is started or when it is restarted at the beginning of the season, the
pool water must be heated by several degrees to reach the desired temperature (set point).
In addition to minimising heat loss from the pool (use of a cover), it is often necessary to leave the
filtration system running 24 hours a day, so that the heat pump is also running 24 hours a day to
heat the water to the set point in an acceptable time.
When taking these precautions, the initial heating period could take between 2 and 4 days
depending on the daytime and night-time hours (although the air temperature may be high during
the day, nights are often quite cold at the beginning of the season).
