If the desired flue gas temperature of 350° C has not been achieved within 15 minutes, the remote control
will activate a re-stoking alarm even if there still might be wood and flames in the combustion compart-
ment. The re-stoking alarm can seem misplaced, but it is activated because the temperature climbs too
slowly. Re-stoking with small pieces of kindling wood can often result in a faster increase in temperature.

hot air from the room to enter the chimney (heat loss). This might on the other hand result in a very
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.

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.
The Thermostat Function
The HWAM Autopilot IHS
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. For environmental reasons
the recommended flue gas temperature should always be a min. of 350° C.
Stoking
When the stoking alarm on the remote control sounds, the stove is ready for stoking. The remote control
will recommend the amount of wood you should use.
Small amount of wood
(700 - 1200 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.
Place two pieces of wood (5-8 cm in diameter) horizontally in the bottom of the
combustion compartment. Place 5-8 pieces of kindling randomly on top. Place
two fire-lighters in between the top layers of kindling. Press the remote control
twice to activate the symbol of lighting up. Light up the fire-lighters and close the
stove door. Adjust the temperature selection mechanism on the remote control
to the desired heat level.
