Fig. 55 -- Space Thermostat Connections
If the 50TCQ unit has an economizer system and
free--cooling operation is required, a sensor representing
Return Air Temperature must also be connected
(field--supplied and installed). This sensor may be a T--55
Space Sensor (see Fig. 51) installed in the space or in the
return duct, or it may be sensor P/N 33ZCSENSAT,
installed in the return duct. Connect this sensor to TB1--1
and TB1--3 per Fig. 52.
Configure the Unit for Thermostat Mode —
Connect to the CCN bus using a CCN service tool and
navigate to PremierLink
t
Configuration screen for
Operating Mode. Default setting is Sensor Mode (value 1).
Change the value to 0 to reconfigure the controller for
Thermostat Mode.
When the PremierLink controller is configured for
Thermostat Mode, these functions are not available: Fire
Shutdown
(FSD),
Remote
Occupied
(RMTOCC),
Compressor Safety (CMPSAFE), Supply Fan Status
(SFS), and Filter Pressure Switch (FILTER).
