Controller Operation

The pool heating/cooling request works following the logic
of priority described in the Comfort Module manuals.
The pic. 5 shows the curve used to calculate the Pool priority.
When the pool priority is higher than the Room and Sanitary
priority, the system switchs to perform pool heating/
cooling.
In the pic. 5:
P=Priority calculated
T=Pool water temperature
A=Pool water temperature setpoint (Par. 1 of Variable Table)
B=Delta temperature for priority 0.5 (Par. 75 of Variable Table)
C=Delta temperature for priority 1 (Par. 76 of Variable Table)
The priority will be calculated only when the Flow Switch
detects water flow (if installed and mapped).
If there is NO Pool water temperature sensor, the priority will
be always 0.5.
Mode selection
See the Comfort Module and User Interface documentation.
It's possible to select the mode of the zone by:
The Pool Kit works communicating a heating demand and
a priority to the Comfort Module, priority is compared with
the priorities from zones and sanitary tank.
Using the User Interface, if the mode set is Not OFF, and the
schedule mode is ON, the water pump will be turned on and
the water temperature setpoint requested will be compared
with the Water Pool Temperature, to calculate the priority.
Using the Dry Contact, the user can set the Pool On or Off,
but the mode (heating/cooling) has to be set using the
User Interface by the Virtual Zoning feature if no Pool User
Interface is used (refer to User Interface Manual). When the

mode is On, the water pump is turned on and priority will
be calculated.
In all the case, water pump behaviour also depends on
Par. 11.2 setting and Pool Temperature.
If the Pool Temperature Sensor is used, to read the right Pool
Temperature, don't stop the water pump when the set point
is reached.
If flow switch is installed, priority is 0 if no flow is detected.
Pool Antifreeze protection
If enabled on Varbiale table Par. 11.0, and if the Pool
Temperature read by Water Pool temperature sensor (ref.
8 of pic. 4) is below the value at Par. 12 of Variable Table, the
Pool Kit starts to heat the Pool.
This protection is active only when the Pool mode is Off, and
main system mode is not cool.
Climatic Curve
The temperature of the water provided to the pool is
calculated by the Climatic Curve.
It works using the Outdoor Air Temperature, according to
the graph in pic. 6 and the values set in the Variable Table
(Par. 52÷60).
The Pool Kit adjust the temperature requested to the
Comfort Module in order to achieve its setpoint.

This function prevents the icing of the water in hydronic
