OPERATING GUIDE FOR DVS G3
®
AIR-WARMER
Introduction
The optional DVS
®
Air-Warmer pre-warms cooler air from your roof space before it
enters your home through the ceiling outlets. The Air-Warmer is designed to take
the ‘chill’ off incoming air from the DVS
®
during cooler months, NOT to warm your
home or replace your existing home heating.
The Air-Warmer’s thermostat is pre-set at 28ºC for economical use. Depending on
several factors including the roof space air temperature, fan speed and air flow, length of time the Air-
Warmer has been operating and the distance from the Air-Warmer to individual ceiling outlets, the air
entering the home will typically range between 20ºC and 25ºC. The incoming air may not feel especially hot
or warm, but feel about the same temperature as, or slightly warmer than your home. However, because the
incoming air is moving, the temperature felt by the skin can feel cooler than it actually is.
NOTE: Even when the DVS
®
Air-Warmer is operating you will still need to use normal home heating to
maintain a comfortable living environment, and to assist condensation control.

Mode
Use the MODE button to select whether the DVS
®
Air-Warmer operates on Auto, Timer, or Dual modes, or is
turned Off (as shown).
We recommend operating your Air-Warmer on Dual function for maximum
energy efficiency. When set to Dual, the Air-Warmer will only turn on between
the pre-selected times as set in the TIimer menu and WHEN the roof space
temperature drops below the temperature selected in the Auto menu.
Note:
The currently selected mode of operation will be displayed on the current
status screen. Whenever the Air-Warmer is operating, shimmering lines will appear over those displayed
words.
