Temperzone Unit Controller 6 - Operation and installation- Hydronic

1. Introduction

The temperzone Unit Controller 6 (UC6) is the successor to the OUC4 controller.
The UC6 provides increased capability and flexibility in indoor-, outdoor- and
packaged units. The complete controller combines the µPC controller board from
Carel plus an interface board to connect temperzone standard sensors and plugs.
The UC6 receives requests such as "Unit On/Off", "Start compressors", "Activate
HEAT (Reverse Cycle)" and transfers these requests to the outputs after enforcing
safety timers. The UC6 ensures unit safety by continuously monitoring input
signals such as pressures and temperatures. Beside the normal controls and unit
safety the UC6 has many other functions, for example head pressure control,
capacity control, superheat control, serial communications and more.

2. Features

The UC6 has the following features:
Normal controls:
- One controller can manage two complete refrigeration circuits
- Two drivers for uni-polar electronic expansion valves (EEV)
- Outdoor fan control
- Reversing valve change over management
- Variable speed compressor management
- Crankcase heater control
- BMS interface with optional board(BACnet/IP, Ethernet, MS/TP)
- DRED input and control
Safety functions:
- Compressor minimum cycle time, minimum run time, minimum off time.
- High pressure protection via high pressure transducer
- Low pressure protection via low pressure transducer
- Loss of refrigerant protection
- Indoor coil frost protection
- No water flow protection
- Water float protection
- Low water output temperature protection
- Repeat fault lock out
- Error code display
- Alarm logging
Commissioning functions:
- Commissioning mode
- Automatic test sequence
