Heat Transfer Summer Add-On Kit 150Ø

HTS1 Summer Kit Add-On

Cool your home the smart way—no bugs, no open windows, no fuss.

After a hot summer’s day, your home can feel stuffy and slow to cool down. The HTS1 Summer Kit Add-On brings in fresh, filtered evening air to help cool your home naturally—without dust, insects, or the security risk of leaving windows open.

Cool air is gently drawn in through an under-eave inlet and circulated through your existing heat transfer system, helping create a more comfortable environment on hot, humid nights—so it’s easier to relax and sleep.

When the Summer Kit is activated, your heat transfer inlet is sealed off by a motorised damper, so warm air isn't pulled from the heat source room. Instead, filtered air from outside moves through the system. Due to natural air pressure, gentle circulation still occurs throughout your home, even if not all rooms are directly ducted.

The air is filtered using a G2 inline filter that helps capture dust, leaves, and insects—keeping the incoming air clean and fresh.

How It Works

• A motorised damper switches the airflow from warm indoor air to cool outdoor air

• The air is drawn in via an inlet grille under your eaves

• The system uses your existing ducting and outlet grilles to circulate air

• Controlled via a wall switch, using your current thermostat controller

• Simply set your thermostat to a lower temperature (e.g. 15°C), and the Summer Kit will activate when the room rises above it
