Congratulations on your new wood-burning stove complete with a HWAM Autopilot IHS

TM

IHS is short for “Intelligent Heat System”, which is a digital control of the combustion in your new 
wood-burning stove. The purpose of the HWAM Autopilot IHS

TM

 is to control the combustion in an 

environmentally optimal and economically efficient way, with a view to generating greater user comfort. 

The HWAM Autopilot IHS

TM

 is a completely new patented technology, which electronically adjusts the air 

supply to the combustion chamber. Your new wood-burning stove continually measures the temperature 
and the oxygen levels of the combustion. Moreover, it is programmed to supply oxygen to the fire through 
three important air inlets in the right amount, and at the right time and place in the combustion chamber. 
Via a simple remote control, the user can adjust the thermostat to the desired heat level, while continually 
receiving information about room temperature and optimal stoking times that ensure environmentally 
friendly and economical combustion.

Your new wood-burning stove and the HWAM Autopilot IHS

TM

 will ensure the cleanest possible combus-

tion as well as a good fuel economy, regardless of external conditions such as the type of firewood used, 
the chimney, the user’s experience, and other external circumstances. 

The HWAM Autopilot IHS

TM

 consists of the following components: 

• 

Air box: the Air box contains a printed circuit board/software, as well as three motors that control 
primary, secondary, and tertiary combustion air. The fresh air system can be mounted on the Air box 
to the rear or in the bottom.

• 

Two sensors: a temperature sensor and an oxygen sensor transmit information from the wood-
burning stove to the Air box.

• 

Remote control and wall-mounted stand: the remote control, complete with batteries, is placed at a 
minimum of two meters from the wood-burning stove. The wireless remote control measures the 
room temperature and transmits the information to the Air box. 

• 

Electricity supply: from the Air box to the nearest wall socket.
