Automatic summer ventilation (if fitted)
The purpose of Automatic summer ventilation is to deliver a continuous supply of fresh filtered
air from outside the roof space by automatically changing the air source to draw from the
external vent when the roof space air becomes too warm. This means you can ventilate your
home throughout the summer months without the need to leave windows open during the day
or night (thus reducing pollen, dust and insects in your home).
In some weather conditions the outside air is too warm to ventilate the home. In this instance
the system will behave normally and reduce delivery to an ‘idle’ so as not to warm the home.
The Automatic summer ventilation function can be set to work manually or automatically.
Note: This is an optional extra and will not appear on the control panel unless installed.
•
In Manual mode you can set the Automatic summer ventilation function to be on for a fixed
time, from 30 minutes to 2 hours. After this time the Automatic summer ventilation will
automatically switch off.
•
In Auto mode you can set the Automatic summer ventilation function to switch on
automatically if the temperature in your home rises above your “Set temperature”.
Manual mode
To switch the Automatic summer ventilation function on or off manually:
•
Press the Menu button briefly.
•
Use the down arrow to select Summer vent and press OK.
•
Use the down arrow to select Manual [0] and press OK.
•
Use the up and down arrows to select the amount of time you want the Automatic summer
ventilation function to run for (30, 60, 90 or 120 minutes), or to turn it OFF.
•
Press OK to confirm your selection, then press the Menu button repeatedly until you return
to the Main Screen.
Automatic mode
To set the Automatic summer ventilation function so that it switches on automatically if the
temperature in your home rises above your Set temperature:
•
Press the Menu button briefly.
•
Use the down arrow to select Summer vent and press OK.
•
Use the down arrow to select Auto and press OK twice.
•
The automatic summer ventilation function will now work based on the “Set
temperature” set from the Main Screen.
•
Press the Menu button repeatedly until you return to the Main Screen.

Air Transfer (if fitted)
The purpose of air transfer is to deliver a supply of warm air from the warm room and delivering
this to the colder part of the house by automatically changing the air source to draw from the
warm room with excess heat (eg. The living room with a wood burner). In air transfer mode
the system will not ventilate, but will merely redistribute existing air around the house. This
function lets you set when and at what temperature the Air transfer mode will switch on. If
you have this option installed then you will also have a separate temperature sensor near your
home’s main heat source.
The Air Transfer function is reactive to the room set temperature and the actual room
temperature. This is regardless of the ‘mode’ selected. So; if the room temperature at the
control panel is equal to or warmer than the set temperature (this is the main system set
temperature, not the automatic mode temperature for air transfer,
see page 12
) then little or
no air will be transferred.
The Air transfer function can be set to work manually or automatically.
•
In Manual mode you can set the Air transfer function to be on for a fixed time,
from 30 minutes to 2 hours. After this time the Air transfer will automatically
switch off.
•
In Automatic mode you can set the Air transfer function to come on:
•
at certain times (timer), or
•
above a certain temperature (according to the sensor), or
•
a combination of both (i.e. you can set the Air transfer to come on above a certain
temperature during the “On” part of the timer’s cycle).
Manual mode
To switch the Air transfer function on or off manually:
•
Press the Menu button briefly.
•
Use the down arrow to select Air transfer and press OK.
•
Use the down arrow to select Manual [0] and press OK.
•
Use the up and down arrows to select the amount of time you want the Air
transfer to run for (30, 60, 90 or 120 minutes), or to turn it OFF.
•
Press OK to confirm your selection, then press the Menu button repeatedly
until you return to the Main Screen.
