Flow Switch (ref. 6 on pic. 4)

It's strongly suggested to use a flow switch on the system.
The pool control logic uses this sensor to detect if the pool
is operative or not.
When the flow switch detects water flow, the priority is

Three way valve (ref. 4 on pic. 4)

This valve drives the water to the pool exchanger when pool
heating/cooling is required.
This valve is not optional and must be placed on the same
hydraulic side of the Sanitary water valve.

Water Pool temperature sensor (ref. 8 of pic. 4)

This sensor detects the temperature of the water pool. It is
used to calculate the priority and the heat/cool demand of
the pool.
This temperature is also used to change the leaving water
setpoint calculated by the Climatic Curve (±4°C).

Leaving Water to pool temperature sensor (ref. 9 of pic. 4)

It probes the temperature provided to the pool.
The control acts to provide water at the setpoint calculated
with the Climatic Curve, driving the Proportional Valve (if
available) and asking the right water temperature to the
Comfort Module.

Water to heat exchanger temperature sensor (ref. 7 of pic. 4)

It used to better calculate the water temperature requested
to the Comfort Module.

Pressure Switch

It's possible to connect a pressure switch on water pipes (on
the Comfort Module side). When the water pressure is below
the pressure switch preset value, the Pool Kit communicate

calculated and the software runs all the logic dedicated to
the pool.
If the Flow switch is not installed, it is considered as
detecting flow.
On the Variable Table of the Comfort Module, set the Par.
107 according to the real position of the valve.
It is strongly suggested to install this sensor, if this sensor is
not installed, the control always considers a priority of 0.5.
It used also to avoid to drive too hot water to the pool. If
the water provided to the pool is higher than 5°C then the
leaving water setpoint, the control stops the pool heating.
It's strongly suggest to install this sensor.
If this sensor is not installed, the Pool Kit can't operate to
achieve the best efficiency.
the pressure error and stop the heating production.
In case of pressure fault, the control commands the shut off
valve to close, if installed.
