Easy, modern and comfortable with the... With the user-friendly VGA color touch-screen controller, the burning-process, as well as heating circuits, a hot water tank, buffer tank and a solar system can be controlled. A central control unit for: Buffer management Back flow elevation (pump and mixer valve) Domestic hot water preparation Controlled heating circuits (pump and mixer valve) Solar circuit control Frost protection The convenient menu and simple screen layout with schematic 3D-representation ensures maximum user-friendliness. The modular operation of the T-CONTROL offers extension possibilities up to 55 modules. As a result, the central control unit can optimally coordinate the processes of the combustion control (lambda probe control), buffer management, back flow elevation, heating circuit, hot water preparation, solar and more. 4
... central control unit T-CONTROL Remote access to the control via the myherz-portal As an additional option, the T-CONTROL offers the possibility for remote visualization and remote maintenance via smartphone, PC or tablet PC. The handling is the same as in the Touch-Control directly on the boiler. The processes and parameters can be read and modified any time from anywhere. Further advantages of the T-CONTROL: power-saving standby mode status and error messages via e-mail data transfer and software updates via USB stick possibility of Modbus-communication easy and clear presentation of the functions from various components (heating circuit pump, hot water tank loading pump, circulation pump, mixing valve, switching valve, actuator motors etc.) Cascade switching With the HERZ T-CONTROL up to 8 boilers can be switched in cascade. That means, several boilers are merged in order to achieve a higher performance. A special advantage of the cascade arrangement is the efficient utilization of the boiler at lower heat consumption (eg in the transitional period). 5
Benefits and details... T-CONTROL - the user-friendly control with touch display Central control unit as standard for: Buffer management Back flow elevation (pump and mixer valve) Domestic hot water preparation Controlled heating circuit (pump and mixer valve) Frost protection Simple screen design and convenient menu guide. Extension modules up to 55 modules possible (heating circuits, solar-use, second buffer etc.) 2 Made of high heat-resistant steel - for longest lifetime High heat resistant stainless steelcombustion chamber 4 3 5 Automatic cleaning via tipping grate. T-CONTROL central control unit Complete cleaning of the grate due to automatical tipping on a cleaning device. No manual cleaning requirement. Due to the clean combustion grate an optimum air supply is guaranteed. The ash from the combustion chamber is dropped into the large ash bin below. The HERZ pelletstar is depending on the fuel quality several weeks maintenance-free. 2. High heat resistant stainless steel combustion chamber 3. Automatic tipping grate for complete cleaning 6
...of the HERZ pelletstar 0-60 Energy saving combustion due to the lambda probe 9 8 A built in lambda probe, which monitors continuously the fl ue gas values, detects fuel quality changes and ensures optimum combustion and low emission values. The lambda probe controls the air supply and ensures a complete combustion, even in part load operation. The results are low fuel consumption and lower emission values even with different fuel qualities. 0 7 Automatic cleaning of the heat exchanger 6 The heat exchanger surfaces are automatically cleaned via the integrated turbulators, even during heating operation and therefore no manual cleaning is necessary. A consistently high level of effi ciency by purifi ed heat exchanger surfaces means low fuel consumption. The integrated, extractable ash boxes allow an easy ash disposal. 4. Automatic ignition via hot air fan 5. Ash-bins for combustion and fly-ash are easy accessible from the front, easy to handle 6. Certified back fire protection flap (BFP) 7.

Full automatic pellets discharge systems HERZ offers a variety of solutions to store the wood pellets and to discharge the fuel via various systems to the boiler. Whether a room discharge with fl exible screw, suction system, agitator or with a rigid pellet screw: Due to the wide range of discharge variants HERZ has the optimal solution for each room and space situation. If there is no pellet storage room available, there is also the possibility of an underground tank outside of the building or a bag silo, which can be placed for example, directly in the boiler room. Discharge via fl exible screw The room discharge with a fl exible screw is an easy and energy saving solution to empty the storage room in an effi cient way. 2 3 5 4. Filling nozzle The pellets are blown via a fi lling nozzle into the storage room. At least fi lling nozzle and suction nozzle are required because parallel to the blowing operation the produced dust and the necessary conveying air are sucked away. 2. Impact mat An impact mat serves to protect the pellets during the blow in and is mounted opposite of the fi lling nozzle. 3. Slide ramps In order to empty the storage room completely a sloping fl oor is recommended. 4.

Storage systems from HERZ System bag silo Room discharge with flexible screw from a bag silo If no pellet storage room is available, there is the possibility of a bag silo. The bag silo can be placed directly in the boiler room (depending on national regulations). If the bag silo is placed a floor higher the pellets transport is done via a flexible discharge screw with chute pipe system. Suction discharge from a bag silo 4
The silo The advantages in detail Easy and fast assembly The bag silo can be installed & assembled easy and fast. If the silo is not on the right place after installation, it can be easily rearranged. Clean The special antistatic polyester fabric prevents that dust escapes from the silo, whereby a clean filling and a dust-free operation is possible. Careful pellet storage The pellets are protected during filling by the integrated impact mat inside of the bag silo. In addition, the silo provides an optimal environment for the careful storage of the fuel. Individual positioning The place of installation of the silo can be selected individually. Due to the variety of the pellets discharge systems HERZ offers for each place and room situation the optimum solution. The HERZ bag silo is available in different sizes with storage capacities from. up to.7 m³. User-friendly The filling level of the pellets is due to the transparent fabric easy to read from the outside. Additionally, the system offers the cost-effective acquisition and full automatic & maintenance-friendly operation. System ground storage If there is not enough space to store the pellets inside the building, there is the possibility of a ground storage outside of the building. The fuel is transported to the boiler via suction system. 5

HERZ domestic hot water module & buffer tank Buffer tank fresh water module ILLUSTRATION OF FUNCTION cold water The HERZ fresh water module is a domestic hot water preparation unit which is working in continuous fl ow mode. The fresh cold water is heaten up via a plate heat exchanger with water from the buffer tank. The fresh water module is characterized by its compact design, low pressure drop, low water content and easily accessible and clearly arranged connections. THE BENEFITS: Domestic hot water hygienic & fresh Easy to install Very compact (low space required) Useful supplementation for your heating system: HERZ buffer tanks In the use of a buffer tank the generation of energy takes place over a longer period. As a result the number of boiler starts is reduced and the effi ciency of the entire system increases. A buffer tank ensures a constant heat supply for different heating circuits (eg underfl oor heating and radiators) and ensures optimum operating conditions. 8
