The AVHRU1 unit is designed to constantly ventilate the room with fresh warmed air. The air exiting the room passes over an aluminium heat exchanger and heat is transferred at an efficiency rate of up to 80% to the air coming into the room.

A remote humidistat sensor monitors the humidity level and switches the unit to boost if the set levels are exceeded. The unit automatically returns to trickle mode.

The high efficiency aluminium heat recovery unit is up to 80% efficient in trickle mode, exceeding the efficiency of plastic units.

The remote humidistat and transformer can be mounted where convenient and incorporates an externally adjustable humidistat which can be set and locked at installation.

A pull cord allows the boost setting to be manually controlled.

A photoelectric cell can be incorporated into the operation of the unit to ensure the unit does not go into boost mode when the room is dark.
