Summer Vent Kit
Your Dry-Matic is designed to provide summer time ventilation when it is hot in the ceiling by providing a DM controller
override that operates fan at full speed (approx double the airflow of DM in heat r
ecovery mode) and drives a motorised
diverting branch that draws cool fresh air through the soffit from outside.

Cleaningthelters
Although the Dry-Matic is designed to run continuously for
years, the lters do need cleaning every 8 months or so for
optimal performance (clean at least yearly).
If the lter timer is activated, the hall controller display will start
ashing Dirty Filter to indicate it is time to clean the lters.
The white lter bag can be machine washed on gentle cycle
or hand washed - vacuum rst to remove excess dust.
Alternatively replace with a new one.
The carbon lter inside the lter box should be replaced every
year.
You may prefer to get a professional to climb into the attic
space to access the lters.
Dry-Matic Maintenance
Optional Summer Vent Kit
The Dry-Matic Summer Ventilation Kit is an optional add-on for Digital
Dry-Matics.
It can be added during installation or several years after installation.
The digital hall controller can be commissioned to control the motorised diverting
branch damper, directing air intake from the cooler outside air for summer
months.
Again, the air intake filter, and the inline ‘Sock’ will need cleaning as above.

Optional Heater
Some Dry-Matic units have been tted with a thermostatically controlled duct
heater that tempers the incoming air when it is cold in the attic.
