cold chimney when the stove is lit. In certain cases it is necessary to assist the draught in the chimney
by burning a couple of newspaper pages on top of the wood ready to be lit. Read more on www.hwam.
com about the function of the chimney.
Important!
The ashpan must not be opened when lighting up. It must always be closed when the stove is in use.
Otherwise the stove’s intelligent control system does not function. The door should only be opened
when lighting up, when restoking, and when cleaning the stove. Never leave a stove before there are
lasting flames in the wood after firing!
The Thermostat Function
The HWAM Autopilot IHS
TM
will in general have an environmentally friendly combustion and adapt
to the desired room temperature. The thermostat function is designed as a radiator valve. The user
enters a desired heat level, which suits the room in which the stove is installed. When the thermostat
is set at a heat level, the control function will adapt to this temperature.
If the room temperature is lower than the desired heat level, the control function increases the flue
gas temperature in order to increase the heat radiation from the stove.
If the room temperature is higher than the desired heat level, the control function decreases the
flue gas temperature, thereby giving the layer of embers as long a life as possible before re-stoking.
This will reduce the heat radiation from the stove and facilitate re-stoking without having to light
up the fire anew. If the room temperature drops below the desired level, the ember phase will be
shortened, and the system will activate a re-stoking alarm. The system will signal that a re-stoking
is due at the flue gas temperature of 180° C, and at 100° C the system will enter standby mode and
all dampers will close.
Should the room temperature be much lower than the desired heat level, the control function
increases the flue gas temperature. If a satisfactory increase in temperature does not occur, the
control will activate a re-stoking alarm, since it expects that more wood is needed to increase the
heat level in the room.
If the room temperature after a new re-stoking still does not reach the desired level, the water
content in the firewood may be too high or the draught in the chimney too weak. The IHS system
always strives for a sufficiently high flue gas temperature to ensure an environmentally friendly
combustion.
Stoking
When alarm for re-stoking sounds the stove is ready for re-stoking. The alarm for re-stoking will come
via the room temperature sensor or the acquired remote control. The app IHS Smart Control
TM
will
also come with a notification that it is time for re-stoking if the app is opened. For more information
on the app, see separate manual.
The amount of wood that is used for re-stoking should be adjusted based on the current heat demand.
Small amount of wood Medium amount of wood Large amount of wood
(700 - 1200 g) (1000 - 2000 g) (1800 - 3000 g)
In terms of combustion technique, you should always stoke the stove with at least two pieces of wood
at a time even if you only use a small amount of wood. You can also choose not to restoke. After a
while the stove will then automatically go into hibernation.
Important!
Never leave a stove before there are lasting flames in the wood after re-stoking!
During combustion, the outer surfaces of the stove will become hot, and due care must
therefore be shown.
