Product Overview

Controls & Features

The following describes the controls and features of the energiSava

®

 325. 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 removable covers 

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:

• Normal 

Solid Light - 

Unit is running at continuous speed. 
Flashing light - 

Unit is running at setback speed.

• Frost 

Unit is in automatic frost protection mode.

• Filter 

Filters require change.

• Boost 

Solid light - Unit is running at boost speed. 

Flashing light boost alert is active.

• Summer
