Controls & Features
The following describes the controls and features of the energiSava
®
500. Ensure the supplied
control is adequately labelled, indicating function clearly.
The unit can be controlled by various volt free
switches and sensors. Ensure all controls are
adequately labelled, indicating their function clearly.
Filter Covers
The filters are located behind a removable cover
on the front of the unit.
Continuous Speed
Continuous speed is the normal continuous
extract and supply air flow running speed of the
units.
Auto Setback Speed
Setback speed is used to reduce ventilation rates.
Setback speed is automatically set at the mid
point between minimum possible continuous
speed and the selected continuous speed. The
setback speed can be enabled by connection of
a volt free one-way switch.
Boost Speed with Overrun Timer
Boost speed increases the extract and supply
air flow. Boost speed is configured with step-
less independent fan controls and includes an
overrun timer variable between 0 and 60 minutes.
The boost speed can be triggered by any device
which provides a volt free one-way switch, such
as a PIR, thermostat, humidistat or a standard
one-way switch.
If the unit is left in boost (latching switch) for
longer than 2 hours the overrun timer is disabled
meaning the unit will return to continuous speed
as soon as the switch holding the unit in boost
is released.
Status Indicator (included as standard)
The status indicator is a low voltage hard wired
remote LED ventilation information panel, to fit a
standard UK patress or recessed backbox. The
indicator has six LEDs which display:
