The SmartVent Positive2 System
SmartVent Positive2 is a positive pressure system which uses
air taken from the roof cavity to ventilate your home.
System Enhancements1)
Summer Feature
Adds outside air as second air source option so that your
system can provide continued quality ventilation in warmer
months and especially so when the roof cavity air temperature
exceeds that of the outside air.
Heat Transfer
Used to transfer any excess heat from your lounge to your
bedrooms.
Tempering Heaters
Designed for situations where supply air temperatures are too
cool.
When system enhancements are added, your system can offer greater options
in how it operates.
The options can override or influence one another as in the following examples.
Example: When the environment in your home meets your chosen heat transfer
condition the ventilation and tempering heater functions deactivate.
Example: When the system is ventilating and conditions are met for the heater
to turn on, the speed of the fan will be influenced by the heater function.
1) For more information about SmartVent system enhancements, contact 0800 140 150 or email [email protected]

Ventilation
AUTO Mode
- Your SmartVent Positive2 system chooses where to draw air from and at what
speed depending on temperature.
- You select the set temperature you want it to be in the home (i.e. 22°C
(default)) and the system will work on the best air source to achieve your set
temperature1).
- For example, if you set your system to 22°C while the current house
temperature is 20.3°C, the control system measures the temperature of the
incoming air and alters the fan speed to suit. If the temperature of the
incoming air is 22°C or higher it will operate at a high speed to use the free
heat to try and increase the overall house temperature. If the incoming air is
lower than 22°C, the fan speed would decrease to reduce the cooling
effect
2).
1) Your system is not a heating or cooling device, this parameter is set to reduce nuisance over-
heating or over-cooling of your home.
2) Additional features are available when low temperatures are present. See RECYCLE mode, HEAT
TRANSFER and TEMPERING HEATER

Heat Transfer
When HEAT TRANSFER is ON, the fan speed will be low when the lounge
temperature exceeds chosen temperature, and it will gradually speed up as your
lounge gets warmer.
HEAT TRANSFER mode has priority over VENTILATION mode. To
ensure your home stays regularly ventilated, we recommend you use the timer
function to turn HEAT TRANSFER OFF during the day, the middle of the night
and early morning. We also recommend HEAT TRANSFER is set to ON in the
evening.
OFF Mode
When HEAT TRANSFER mode is OFF, the system will operate in
VENTILATION mode.
