n Controlling the pool circuit
The control system can be used to manage a swimming pool circuit
in 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 the MB
outlet on the connection terminal block. The temperature
MAX.CIRC.B is then guaranteed during comfort periods on
programme B in summer and winter alike.
4 Connect the swimming pool sensor (package AD212) to the S
DEP B inlet on the connection terminal block.
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 be
kept. The control system only regulates the primary circuit
(boiler/exchanger).
4 Connect the primary circuit pump (boiler/exchanger) to the MB
outlet on the connection terminal block.
The temperature MAX.CIRC.B is then guaranteed during comfort
periods on programme B in summer and winter alike.
