KNX HVAC module - HDL Automation

Name: KNX HVAC module - HDL Automation
Brand: HDL Automation

KNX HVAC module from HDL belongs to the HDL KNX/EIB series. Supports control of heating, cooling, and high/medium/low fan speed. Includes 7 independent floor heating control channels that can be set. In conjunction with a digital temperature sensor, the actuator achieves precise temperature control. In addition, 5 switch output channels and 2 DC0-10V output channels can be set for staircase lights and other requirements.

Features

7 independent floor heating control channels;
Up to 7 digital temperature sensors supported;
5 relay output channels;
2 DC0-10V output channels (10mA/CH);
Fan speeds: high, medium, low;
Working modes: heating, cooling;
Operation modes: comfortable, standby, night, protection;

Main functions: fan speed, valve status report, local 7 channels temperature sampling, local temperature report, operation time statistics, channel status response, power-on status recall, power-off status saving, staircase lights, on/off delay, protection delay, PWM control output; Active control and passive control: more flexible to work in conjunction with panels by different manufacturers; When in active control mode, this module can work in conjunction with panels without PI algorithm, for example M/DLP04.1; When in passive control mode, this module can work in conjunction with panels with an algorithm, for example, Siemens 5WG1.

Advantages

Centralised HVAC control: consolidates multiple HVAC functions in a single KNX device, reducing system complexity;
High control flexibility: supports both autonomous and system-driven control architectures (active vs passive modes);
Precision temperature management: integration with multiple temperature sensors enables accurate zone-based control;
Reduced installation footprint: combines relay outputs, analog outputs, and heating control in one module;
Scalability in building automation systems: suitable for multi-zone residential and commercial applications.
