Space Sensors —
The PremierLinkt controller is factory--shipped configured
for Space Sensor Mode. A Carrier T--55 or T--56 space
sensor must be us ed. T--55 space temperature sensor
provides a signal of space temperature to the PremierLink
controller . T--56 provides same space temperature signal plus
it allows for adjustment of space temperature setpoints from
the face of the sensor by the occupants.
Connect T--55: See Fig. 53 for typical T--55 internal
connec tions. Connect the T--55 SEN terminals to TB1
terminals 1 and 3 (see Fig. 54).

Connect Thermostat —
A 7--wire thermostat connection requires a 24--v power
source and a common connection. Use the R and C
terminals on the CTB’s THERMOSTAT connection strip
for these. Connect the thermostat’s Y1, Y2, W1, W2 and
G terminals to PremierLink TB1 as shown in Fig. 57.
If the 50HC unit is equipped with fact ory--installed smoke
detector(s), disconnect the factory BLU lead at TB1--6
(Y2) before connecting the t hermostat. Identify the BLU
lea d originati ng at CTB--DDC--1; disconnect at TB1--6
and tape off. Confirm that the second BLU lead at TB1--6
remains connected to PremierLink J4--8.

If the 50HC unit has an economizer system and
free--cooling operation is required, a sensor represent ing
Return Air Temperature must also be connected
(field--supplied and installed). T his sensor may be a T--55
Space Sensor (see Fig. 53) instal led 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. 54.
Configure the Unit for Thermostat Mode —
Connect to the CCN bus using a CCN service tool and
navigate to PremierLin k Configu ratio n screen for Operating
Mod e. Defau lt setting is Sens o r Mo de (valu e 1). Chan ge the
value to 0 to reconfigure the controller for Thermostat Mode.
When the PremierLink controller is configured for
Therm ostat Mode, these functions are not available: Fire
Shutdown (FSD), Remote Occ upied (RMTOCC),
Compressor Safety (CMPSAFE), Supply Fan Sta tus
(SFS), and Filter Pressure Switch (FILTER).
