Design for Comfort

01

IAQ Sensors CO2 / PM2.5 / VOCs / TEMP / RH

The control panel is fitted with CO2, RH (Relative Humidity), PM2.5, VOCs and Temperature sensors as standard. There are also temperature sensor at the intake air of the unit, temperature sensor at the exhaust air of the unit, temperature and RH sensor at the extract air of the unit, which they are fitted as standard. The sensors work for the automation of airflows, bypass and defrost. Optional extra external CO2, RH and Temperature sensors are also available for rooms, where up to 8 external sensors can be connected to the control system.

02

Bypass / Defrost / IAQ Automation

When in automation, the fan speed runs at different level according to the real-time indoor air quality data from the sensors, the parameters can be set on the control panel. User can also choose which IAQ indicator to participate the automation mode. In the case of bypass or defrost automation, it runs according to the temperature level set on the control panel. Summer bypass automation runs based on the indoor or outdoor temperature sensors on the unit, user can adjust the comfortable indoor temperature set-point or adjust the comfortable outdoor temperature set-range, while defrost protection runs in cyclical stops of the supply fan based on the temperature sensors on the unit.

03

Boost Function

Boost ventilation is a function that can be triggered when indoor needs a fast circulation of air with outdoor fresh air, for example when after a party where bad IAQ produced, or when indoor humidity is high, for example when after an activity where wet condition produced. Up to 10 external boost switches can be connected to the control system. The time duration can be set on the control panel.

Internal Temperature / Relative Humidity Sensors

Fitted as Standard

There are five level of fan speeds. The two fans on the unit can separately run in different fan speed levels or run in same fan speed levels for the five fan speed levels, so as to achieve an over-pressure or under-pressure needs.
