Options
OFF
The DVS
®
Air-Warmer is permanently turned OFF, unless temporarily overridden by HEAT BOOST.
Recommended when the Air-Warmer is no longer required, e.g. at the end of winter/early spring.
Auto
The DVS
®
Air-Warmer will turn on whenever the roof space temperature drops below the temperature set in
the Auto Set menu. To set the Air-Warmer to automatically turn on when the roof space temperature drops
below, say, 15ºC, set the Auto temperature to 15ºC. The Timer option does not operate under Auto mode.
The Air-Warmer will turn on whenever the roof space temperature falls below the pre-set temperature.
Adjust the Auto temperature setting by using the up and down arrows.
Press the UP arrow to INCREASE the roof space temperature below which the DVS
®
Air-Warmer will turn
on.
Press the DOWN arrow to DECREASE the roof space temperature below which the DVS
®
Air-Warmer will
turn on.
The Auto temperature may be set between -9
o
C and +25
o
C.
Note: The higher the Auto temperature setting, the longer the Air-Warmer will be in operation.
Timer
The DVS
®
Air-Warmer will turn on and off according to the days and times preset in the Timer menu,
irrespective of the roof space temperature. If the roof space is warm, the Air-Warmer may turn on, but once
the output temperature of 28ºC is reached, the G3
®
will automatically reduce the Air-Warmer power and only
use sufficient power to maintain the 28ºC output temperature.
The Timer mode provides up to seven combinations of days and times when the DVS Air-Warmer will switch
on and off. Each programme represents a start and end for a day or a combination of days (e.g. Mon-Fri or
Sat-Sun or Mon-Sun or individual days).
Detailed instructions on setting the Timer are shown below in Section 3.
Dual
This mode combines
Auto and Timer functions (above) so that the DVS
®
Air-Warmer will operate according to
the Timer settings, but ONLY when the roof space temperature is LOWER than the temperature set in Auto.
To utilise Dual, it is necessary to set BOTH a minimum roof space temperature under Auto mode, AND set
your preferred On and Off settings in the Timer mode.
RECOMMENDED for Maximum Energy Efficiency
Note
: If you have both a DVS
®
Air-Warmer and Automatic Summer Ventilation, the Air-Warmer has been
programmed so that if the Air-Warmer is in Auto or Dual mode, the Air-Warmer will not switch on if the
Summer Vent is open.
