Important!
The door must not be opened when lighting up. It must always be closed when the stove is in use. Oth

erwise 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
ames in the wood after ring!
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 ue
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 ue
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 re
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 ue 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 ue 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 rewood may be too high or the draught in the chimney too weak. The IHS system always strives
for a sufciently high ue 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 notication 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
(1000 - 1600 g) (1400 - 2200 g) (2000 - 3600 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 ames in the wood after re-stoking!
During combustion, the outer surfaces of the stove will become hot, and due care must
therefore be shown.
Fuelling with coal, wood briquettes or pet coke
The stove is not approved to use coal or pet coke as a fuel. However, wood briquettes can be used to
fuel the re and should be placed on the embers produced by the burned wood.
Be aware that using fuels other than wood, will cause soot to form on the glass pane.
