ACCESSORIES
2.1: FAN THERMOSTAT ACTION
In this case, the valve is not used (hot or cold water flows freely into the bank) and thermoregulation occurs by tur-
ning the fan on or off. This regulation is associated with both the
heat
and
cool
modes. To prevent the ambient probe
from making reading errors, the
PERIODIC VENTILATION
function is activated in both the cool and heat modes.

2.2: VALVE THERMOSTAT ACTION
In this case, fan management differs depending on whether the appliance operates in
heat
or
cool
mode, as descri-
bed below:
• Cool mode:
the thermostat function opens/closes the valve as required, while the fan is permanently on even
when the thermostat action has been accomplished.
• Heat mode:
the thermostat function opens/closes the valve while the fan is managed with delay times linked to
the
HOT START
and
PERIODIC VENTILATION
functions (described on page 35).
