Page 4: Introduction
Temperzone Unit Controller 6 - Operation and installation- Hydronic Issue 1 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. -

Variable duty units The UC6 can control a variable speed compressor or a digital scroll compressor. Temperzone pre-configures the unit to the correct compressor type; a UC6 service tool is required if the compressor type configuration must be changed. The capacity input signal must connect to input CS (0-1V, duty 10% per 0.1V). -

Temperzone Unit Controller 6 - Operation and installation- Hydronic Issue 1 Suction side superheat is defined by the difference between the evaporating temperature and the compressor suction line temperature. The evaporating temperature normally is calculated from the suction line pressure. -
Page 16: Loss Of Refrigerant Protection (Lor)
Temperzone Unit Controller 6 - Operation and installation- Hydronic Issue 1 The UC6 will automatically reduce capacity of a variable compressor before the maximum value of 42bar / 66°C is reached. When a compressor is stopped due to high pressure it is held off for a period of 3 minutes, after which it is allowed to restart (provided pressure has fallen well below the maximum). -
Page 17: High Discharge Line Temperature Protection (Hdt)
Temperzone Unit Controller 6 - Operation and installation- Hydronic Issue 1 If this temperature falls below the threshold then some amount of ice (frost) is likely to have formed on the indoor coil. When indoor coil frost protection is activated the compressor is stopped for 15 minutes, after which it is allowed to restart. -
