AHU ECB-400 Series
Distech Controls
The ECB-400 Series controllers are microprocessor-based programmable controllers designed to control various building automation applications such as air handling units, multi-zone applications, chillers, boilers, pumps, cooling towers, and roof top units.
BACnet B-AAC 24-Point Programmable Controllers
The ECB-400 Series can also be used for lighting control applications. This controller uses the BACnet® MS/TP LAN communication protocol and is BTL®-Listed as BACnet Advanced Application Controllers (B-AAC).
These controllers meet the requirements of the following applications:
- Air handling units
- Chillers
- Boilers
- Cooling towers
- Heat-exchangers
- Pumps
- Lighting control
This controller has various software configurable universal inputs and software configurable universal outputs, and covers all medium to large-size industry-standard HVAC applications.
Rugged hardware inputs and outputs eliminate need for external protection components, such as diodes for 12V DC relays.
