SCC-300-AHC/SCC-310-AHC Air Handler Terminal Unit Controller
A flexible, feature-rich but cost-effective solution for two-pipe
or four-pipe packaged air handler terminal unit applications. The
SCC-300-AHC/SCC-310-AHC maintains constant zone temperature or supply air temperature
by configurable, energy-efficient, sequenced control of supply fan,
heating sources, cooling source and optional mixed air damper and
exhaust air damper or fan.
- Configurable resistive inputs for space temperature or supply
air temperature (required) with/without bypass button and any
four of: mixed air temperature, setpoint adjust, fan, filter,
window and occupancy sensors.
- Configurable analog input for CO2-based demand control ventilation
or dehumidification control.
- Digital and analog outputs simplify connecting to a variety
of digital, floating and analog-controlled actuators.
- Side loop provides independent control using spare inputs and
outputs for simple HVAC applications.
- Optimize energy usage with optimum start, demand limiting and
occupied/unoccupied/standby setpoints.
- Built-in alarming, trending and scheduling.
- Space Comfort Controller functional profile #8508.
- Easy-to-use LNS plug-in software simplifies configuration.
- Optional DIN rail mounting kit.
Input/Output Summary
- 5 resistive inputs: 10k Ohm thermistor, or dry contact
- 2 analog outputs: 0-10 VDC at 100 mA
- 5 digital outputs:
