Temperzone Unit Controller 6 - Operation and installation 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. -

DI1: Low o DI2: Medium o DI3: High If the system uses a temperzone TZT-100 thermostat then the indoor fan input signals are received from the TZT-100 through the RS485 communications cable. Two types of outputs are available for indoor fan speed control:... -
Page 13: Outdoor Coil De-Ice Control
The UC6 will not allow both systems to de-ice at the same time. Exceptions to this rule exist, for example for units with a common outdoor fan chamber must de-ice the two outdoor coils at the same time. Temperzone configures each unit to the correct de-ice strategy. -
