Controlling the pool circuit

The control system can be used to manage a swimming pool circuitin both cases:

Case 1: The control system regulates the primary circuit (boiler/exchanger) and the secondary circuit (exchanger/pool).

4 Connect the primary circuit pump (boiler/exchanger) to thepump B outlet. The temperature MAX. CIRC. B is then guaranteedduring comfort periods on programme B in summer and winteralike.

4 Connect the pool sensor (package AD212) to the S OUTL B input.4 Set the set point of the pool sensor using key C in the range 5 -

39°C.

Case 2: The pool has already a regulation system that is to bekept. The control system only regulates the primary circuit(boiler/exchanger).

4 Connect the primary circuit pump (boiler/exchanger) to thepump B outlet.The temperature MAX. CIRC. B is then guaranteed during comfortperiods on programme B in summer and winter alike.

The swimming pool can also be connected to circuit C:

4 Make the connection to the terminal blocks markedC.

4 Set the parameters for circuit C.

Hourly programming of the secondary circuit pump

The secondary pump operates during programme B comfort periodsin summer and winter alike.Stopping

n NIGHT

This parameter is displayed if at least one circuit does notinclude a room sensor.

For circuits without a room sensor:

4 NIGHT :DEC. (Reduced): The reduced temperature is maintainedduring reduced periods. The circuit pump operates constantly.

4 NIGHT :STOP (Stop): Heating is shut down during reducedperiods. When installation antifreeze is active, the reducedtemperature is maintained during reduced periods.

For circuits with a room sensor:

4 When the room temperature is lower than the room sensor setpoint: The reduced temperature is maintained during reducedperiods. The circuit pump operates constantly.

4 When the room temperature is higher than the room sensor setpoint: Heating is shut down during reduced periods. Wheninstallation antifreeze is active, the reduced temperature ismaintained during reduced periods.

n Function 0-10 V

This function controls the boiler using an external system thatincludes a 0-10 V output connected to the 0-10 V input. This controlimposes an instruction set temperature on the boiler. It will benecessary to ensure that the parameter BOILER MAX is higher thanCONS.MAX 0-10V.

If the input voltage is less than VMIN/OFF 0-10V, the boiler is off.The boiler temperature setting corresponds strictly to the 0-10 Vinput. The secondary boiler circuits continue to operate but have noimpact on the water temperature in the boiler. If using the 0-10 V inputand a secondary boiler circuit, the external regulator providing this0-10 V power supply must always request a temperature at leastequal to the needs of the secondary circuit.

Theparameter MAX FLOW is equal to the flow in litres per minute in thesolar circuit.Establish the MAX FLOW value with the help of the table below,according to the configuration of the installation and the number orsurface area of collectors.When the flow is input incorrectly, the display kWh will also beincorrect.

The quantity of heat (kWh value) can only be used forchecks carried out for personal reasons.

4 Refer to the boiler's installation and service manual.

7.4.1. Deletion of sensors from the memory in thePCB

The configuration of the sensors is memorised by the PCB. If asensor fault appears whilst the corresponding sensor is notconnected or has been voluntarily removed, please delete the sensorfrom the PCB memory.

4 Press key ? repeatedly until Do you want to delete thissensor? is displayed.

4 Select YES by turning the rotary button and press to confirm.
