DDC Panels
Tor AHU Panel
A DDC panel for controlling and monitoring Air Handling Unit. It controls the chilled water valve and fan, monitors every trip and filter alarm, and reports to Tor Shield.
What it runs
- Supply or return air temperature control by modulating the chilled water valve
- Fan speed through the VFD, on a 0–10 V signal
- Start/stop on schedule or on command from Tor Shield
- Fan status, trip and auto/manual feedback
- Filter and fault alarms pushed to the Tor Shield dashboard and phone
What's inside
- Tor Saturn 521 controller
- Tor Jupiter gateway (812 or 511 GSM)
- 12 V SMPS
- 2-pole 16 A MCB
