FA-UNT111-2

The Johnson Controls FA-UNT111-2 controller is a versatile Unitary Controller (UNT) from the Metasys FA series. This controller supports seamless communication and control in single-room and single-zone HVAC systems. It supports both N2 Bus and Zone Bus connectivity, and it supports easy integration with various system components. The FA-UNT111-2 operates on a 24 VAC power supply with a frequency rating of 50/60 Hz for ensuring stable and efficient performance. It supports 2 analog outputs rated at 0 to 10 VDC at 10 mA. This controller has spade lug terminations. It also supports 6 analog inputs. These inputs can accommodate different devices, including RTD temperature elements (NI, SI, or PT), 0-10 VDC trans. devices, and 2K ohm setpoint potentiometers. The FA-UNT111-2 controller’s operating temperature range is from 32 to 140°F (0 to 60°C). The FA-UNT111-2 features 4 binary inputs that support dry contacts along with a momentary push button at the zone sensor and an accumulative input. This design enhances the unit's adaptability to various input types. The FA-UNT111-2 controller also offers 6 binary outputs that can operate as 24 VAC triacs outputs at 0.5 Amps. Users can select either a low or high side common for added operational convenience. The FA-UNT111-2 controller measures 165 x 163 x 51 mm (6.5 x 6.4 x 2.0 in.) without an enclosure and 173 x 185 x 119 mm (6.8 x 7.3 x 4.7 in.) with an enclosure. It supports isolated N2 Bus connections and Zone Bus connections with an 8-pin phone jack or a terminal block. The FA-UNT111-2 controller meets the FCC Part 15 (Subpart B, Class A), IEEE 472, IEEE 587 (Category A), and UL 916, UL 864 standards.
