Minimum Ventilation Cycles
Definition
Minimum ventilation cycles are activated when the
average room temperature is below the start tem-
perature of fan stage 1. Running the fans even
though ventilation is not required for reducing the
room temperature is useful to reduce humidity lev-
els and supply oxygen to the room. It also prevents
the fans from freezing in winter.
Minimum ventilation timer
The minimum ventilation timer is composed of an
“On Time” and of a “Cycle Time”. The fans stay on
during the “On Time” then stop until the end of the
cycle. This timer is common to all programs of the
controller.
Minimum ventilation fans
Minimum ventilation is ensured by a user-defined
selection of On/Off fans. Refer to section 4.8.2 to
select these fans.
Automatic adjustment of the min. ventilation rate
The controller can automatically increase minimum
ventilation rates over time by increasing the “On
Time” portion of minimum ventilation cycles. Re-
fer to section 6.1.3.

Set the following parameters:
Minimum ventilation status
Select “On” to use minimum ventilation
cycles; select “Off” to disable this function.
Minimum ventilation timer
Set the “On Time” and the “Cycle Time” of
the minimum ventilation timer. The “Cycle
Time” must last longer than the “On Time”.
This timer is common to all programs of the
controller.
This parameter can only be modified while the
minimum ventilation curve is inactive (sec. 6.1.4).
