6.10.7 Minimum/Maximum discharge temperature
When the discharge temperature exceeds the maximum or minimum set of parameters PF16 or PF17 the ventilation is
disabled.
PF15: Enable fan limitation
PF16: Min. temperature of limitation
PF17: Max. temperature of limitation
PF18: Differential
6.10.8 "Intake cycles"
When the temperature control sensor is positioned in the return duct (PG05=1), it is necessary to activate periodically
the return fan in order to measure the room temperature (parameter PC05 to enable).
The cycle is composed of a wait time (PC06) during which the fan remains off as well as a wait time for activation
(PC07) in which the fans will turn on. The cycle always begins with a period of pause; as soon as the fan is shut down
from the control room temperature (satisfactory room temperature), the cycle will terminate if during the activation
phase the regulation ramp of the ambient temperature exceeds the activation point of the fan. With the parameter
PC08 you can decide whether to activate only the pickup fan (PC08=0) or both the return and flow fans (PC08=1)
during air quality control measuring.
Note 1: if the fan control is continuous (PF01=0) the air quality sensor cycle can never be activated and is thus
unusable. If the return fan is not present (PG09=0) this function cannot be used.
Note 2: the fan activation time during the cycle (PC07) must be sufficiently long with respect to the protection time of
the two fans (PF05), to ensure that both fans are able to turn on during the start-up of the air quality measuring
phase (if requested, see PC08).
