1 Introduction

The Bunsen Air is designed to provide automatic constant hot water heating preset to 55℃. If the

cylinder temperature drops by 5℃the Bunsen Air will switch on and run until the target temperature of

55℃is reached, then it will return to Standby mode.

Advanced Settings - The Bunsen Air has 2 Run Time settings, so you can program 2 periods during

which the unit does or does not run during the 24-HR day.

For energy saving, the Bunsen Air has 3 running periods during which you can choose 3 target

temperatures over the 24-HR day. These can be used with or without the Run Time settings.

If an Immersion Heater is wired into the unit, it will be automatically called on to work with the Bunsen

Air unit, to achieve the Disinfection target temperature once a week. The immersion unit is also called

upon along with the Bunsen Air for either Single Boost or for if the Daily Boost is set-up.

The immersion will be called on as a heating back-up, should anything affect the functionality of the

Bunsen Air unit.

Bunsen Air units should always be installed with a secondary heating source. This can be the existing

heating source, or an immersion as a back-up.
