A space temperature sensor must be installed for each zone controller. There are three types of SPT sensors available from Carrier: the 33ZCT55SPT space temperature sensor with timed override button, the 33ZCT56SPT space temperature sensor with timed override button and set point adjustment and the 33ZCT58SPT with liquid crystal display.

Page 23: Primary Air Temperature Sensor Installation
PRIMARY AIR TEMPERATURE SENSOR INSTALLA- TION — A primary air temperature (PAT) sensor is used on a zone controller which is functioning as a Linkage Coordinator for a non CCN/Linkage compatible air source. The part num- ber is 33ZCSENPAT. See Fig. 15. When used on a zone controller, try to select a zone control- ler which will allow installation of the PAT sensor in the main trunk, as close to the air source as possible.
Page 24 PRIMARY AIR INLET PRIMARY AIR INLET ZC — Zone Controller → → → → Fig. 17 — Supply Air Temperature Probe (Part No. 33ZCSENSAT) Locations The CO sensors (33ZCSENCO2) factory set for a range of 0 to 2000 ppm and a linear voltage output of 0 to 10 vdc. Figure 19 shows ventilation rates for various CO when outside air with a typical CO level of 350 ppm is used.

9. Check to be sure the area around the air handler(s) is clear of construction dirt and debris. 10. Check that final filters are installed in the air han- dler(s). Dust and debris can adversely affect system operation. 11. Verify that the zone controller and the air handler con- trols are properly connected to the CCN bus.
Page 31: Configuration
The following sections describe the computer configuration screens which are used to configure the zone controller. The screens shown may be displayed differently when using differ- ent Carrier software. Points Display Screen — The Points Display screen allows the user to view the status of the air terminal controller points.
Page 32: Modify Controller Configuration
SUPPLY AIR TEMPERATURE — Temperature of the air leaving the zone controller downstream of any ducted heat source. Measured by a 10 kΩ thermistor (Type III). This tem- perature is used to control the maximum discharge air to the space when local heat is active. The sensor is not required or recommended for cooling only terminals.

Alarm Routing Control — This decision indicates which CCN system software or devices will receive and process alarms sent by the zone controller. This decision consists of eight digits each can be set to zero or one. A setting of 1 indi- cates alarms should be sent to this device.
Page 34: Linkage Coordinator Configuration
LINKAGE COORDINATOR SCREEN — The Linkage Coordinator Configuration screen allows the user to set the linkage coordinator configuration set- tings. See Table 6. Linkage Master Zone — This decision defines if the zone controller will function as a Linkage Coordinator (Linkage Master) for itself and other zones.

The inclusion of these configuration set- tings does not indicate that Carrier is endorsing this product for pressure dependent operation. In the case of a pressure sensor failure, the zone controller will broadcast a pressure sensor failure message on the CCN bus.

The default PMF value of 2.273 is the correct value to use when the zone controller is used with a Carrier probe in a Carrier air terminal. For terminals and probes supplied by other manufacturers, the PMF must be calculated and entered into the zone controller configuration in order to correctly measure airflow.
Page 40 The calibration gain is used for the fine tuning adjustments which might need to be made to the airflow calculation. This number is calculated automatically by the zone controller after input to the air balance maintenance screen, or it can be input manually at this screen.
Page 41: Options Service Configuration Screen
Start Value: Units F (C) Range 40 to 125 Default Value Ducted Heat — The Ducted Heat configuration is used to con- figure the terminal for ducted heat. If a local heat source is in the duct and requires airflow to provide heat, set the Ducted Heat configuration for yes.

Override — The Override parameter is used to configure the number of hours and minutes the override will be in effect. The user initiates override by pressing the override button on the space temperature sensor. This will cause the schedule to enter into the Occupied mode.
