Basic unit
Kampmann Katherm HK trench heater, ready-to-install floor trench, either for installation in raised or screeded floors, convector-based for heating and cooling with tangential fan convection. Heat and cooling outputs tested in accordance with E DIN EN 16430, parts 1 to 3. Hygiene-certified in line with VDI 6022.
Floor trench made of sendzimir galvanised sheet steel, painted graphite grey on both sides. Height adjustment feet on the side to adjust the trench height, fitted with impact sound insulation, raised floor height adjustment feet with impact noise insulation, for the secure support of the trench. With pre-punched connection openings for water flow and return pipes and electrical connection, on the room side. Floor trench configured for condensation pump kit. Segment panels act as a finger guard for the tangential fan and as frame for the filter, airflow baffle, grille seat and reinforcing stays to strengthen the trench. Central wall acts as an air guide and support for the tangential fan.
Life Cycle Assessment (LCA) data is published in the form of an EPD according to EN 15804 and is available to download from the International EPD System. Registered in the building products platform DGNB Navigator. GWP (phase A1-A3), kg CO2 Äq.2,40E+02. Further calculations possible online.

Condensate tray
Condensate tray has a flow-optimised design, for the simultaneous discharge of condensate and air guidance below the convector. Condensate tray designed as an independent component that can be removed for cleaning and maintenance in accordance with VDI 6022.
Fan
Tangential fan with safety guard. Energy-saving EC fan with 0-10 V input for continuously variable speed control with sound-optimised commutation electronics. Valve controlled via 24 V DC control contacts. All rotating parts have low-noise and maintenance-free bearings. Motor monitoring with internal fault processing.
Even flow through the convector, low power consumption for effective, energy-saving consumption, also sound-optimised for low sound values. Easily removable for cleaning and maintenance due to combined coupling/ball joint system with simultaneous acoustic decoupling. With sound-optimised commutation electronics Factory-wired ready for connection. Valve controlled via 24 V DC control contacts.
Control
- Built-in KaControl MC controller for continuous fan control with motor monitoring.
- For the control of 24 V DC actuators (Open/Closed) for heating and cooling operation.
- With connection option for 5 multifunctional inputs (room temperature, window contact, supply and return temperature, heating/cooling changeover, condensate alarm, sequential control via a 0-10 V signal etc.), unit-specific control and regulation algorithms with the core functions of room temperature control (heating/cooling).
- Timer program with battery-backed real-time clock for four operating modes (Day/Eco/Extra/Off), commissioning function.
- Grouping of up to 10 units and a display to create a control zone using CAN-bus, automatic addressing and communication monitoring of all bus subscribers, continuous synchronisation of all statuses and parameters within the group.
- CAN bus interface and galvanically isolated RS485 interface, each with two terminal blocks for separate connection with daisy chain cabling with a switchable terminal resistor.
- connection of central functions, such as heating cooling changeover to a freely selectable unit within the group.
- Ethernet interface with two RJ45 sockets with built-in switching function.
- KNX-TP interface with socket terminal, all terminals are designed as plugs, wireless communication via Wi-Fi web server for user-friendly operation and for complete password-protected parametrisation.
- protocols can be unlocked via licences: BACnet/IP, Modbus TCP, Modbus RTU, KNX.
- Built-in 24 V DC current measurement.
Grille
