Electrical Wiring Schematics
The following sections detail the internal and client wiring for the Temperzone OPA 211RLTFY(H/V) Econex unit, managed by the UC8 controller.
Internal Wiring Overview (Page 3)
The internal wiring schematic illustrates the connections between the main power supply (L1, L2, L3, N, PE), the UC8 controller, indoor and outdoor fan motors (IFM1, IFM2, OFM1, OFM2), compressor (COMP), electronic expansion valve (EEV), power speed drive (PSD), and various sensors and control components. Key terminal blocks (TB1-TB26) are shown, facilitating power distribution, signal transmission, and fault reporting.
Components like capacitors (CAP1, CAP2), transformers (TR), circuit breakers (CCB, IFCB, OFCB), and relays are integrated into the system.
Client Wiring and Connections (Page 4)
Client wiring involves connecting the unit to the external power supply via an isolator switch and protection. It also details connections for customer BMS (Building Management System) inputs, optional room temperature controllers (like TZT-100), and sensor inputs.
Key Connections and Terminals:
- Power Input: TB1 (L1), TB2 (L2), TB3 (L3), TB4 (N), MIS (Main Isolator Switch).
- Control Circuit: TB5, TB6, TB7, TB8, TB9, TB10, TB11 (24V AC), TB12 (24V COM).
- Analog Controls: Compressor (0-10V) via TB13, Fan (0-10V) via TB14.
- Fault Signals: TB16 (N/O), TB17 (COM), TB18 (N/C).
- Remote Control: LOW IN (TB19), MED IN (TB20), HIGH IN (TB21), COM (TB22), HEAT ON (TB23), COMP ON (TB24), ON (TB25), 0V (TB26).
Sensors and Transducers:
Various sensors are connected to the UC8 controller for monitoring and control:
- Temperature Sensors (Type S): Discharge Temp (DL), Suction Temp (SL), Ambient Temp (AMB), De-ice Temp (DEI).
- Pressure Transducers (Type T): Suction Pressure (LPT), Discharge Pressure (HPT).
DIP Switch Settings:
The unit features DIP switches on the UC8, PSD, and TFC modules to configure operational parameters. Specific settings are provided in tables, indicating which switches to set to 'On' or 'Off' for different functions like fan speed control, compressor operation, and fault reporting.
