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.
Trench chassis made of sendzimir galvanised sheet steel, graphite-grey coated. Modular trench unit, consisting of connection, power and extension module. The connection module contains all the building services interfaces consisting of an electrical connection and control box, EC fan motor, water-side heat exchanger connection and the condensate connection on the waste water side, optimized for simple, time-saving installation. Power module consisting of heat exchanger and tangential fan with continuous cascaded tangential rollers. Extension module for the 4-pipe heat exchanger connection.
With lateral installation aids and step-stable height adjustment, each with impact sound insulation, for secure elevation of the trunking. With pre-punched feed-throughs for water supply and return and electrical connection, on the room side. Trench chassis prepared for condensate pump mounting kit. Segment plates as simultaneous finger protection for the tangential fan and filter fleece support frame, air guide plate, grate support and cross brace for stiffening the duct. Center wall as air guide and mounting plate 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.2,18E+02. Further calculations possible online.

Heat exchanger

High-output heat exchanger, made of round copper pipes with aluminium fins and 1/2-inch valve connection, painted graphite-grey. With sturdy anti-torsion mechanism and simultaneous spray protection when venting. Collector with integral bleed option.

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. High-performance energy-saving EC fan with 0-10 V input for continuously variable speed control, sound-optimised. Integrated controller with variable cable design. Valve controlled via 24 VDC control contacts. All rotating parts have low-noise and maintenance-free bearings. Motor monitoring by integrated active temperature management. With ball bearing with long-lasting greasing.
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. Factory-wired ready for connection. Valve control via 24 VDC 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.
