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. 34.
If the 50TC unit is equipped with factory- - installed smoke
detector(s), disconnect the factory BLU lead at TB1- - 6
(Y2) before connecting the thermostat. Identify the BLU
lead originating 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 50TC 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. 29) installed in the space or in the
return duct, or it may be sensor PNO 33ZCSENSAT,
installed in the return duct. Connect this sensor to TB1- - 1
and TB1- - 3 per Fig. 31.
Configure the unit for Thermostat Mode — Connect to the
CCN bus using a CCN service tool and navigate to
PremierLink Configuration screen for Operating Mode.
Default setting is Sensor Mode (value 1). Change the
value to 0 to reconfigure the controller for Thermostat
Mode.
