System Pilot - Communication Space Sensor
Install the System Pilot and connect the CCN communication bus from it to the units CCN connection on the low voltage terminal board. Configure the unit’s CCN communication element number, bus number, and baud rate. Refer to the System Pilot’s installation instructions for configuring it to be used as a space temperature and attaching it to a unit.
Gen III TEMP Monitor - Linkage Communication
Thermostat (33CSTMT-01)
Install the linkage thermostat. Connect the CCN communication bus from the Stat to the CCN terminals on the field connection terminal board located at the unit control box. Configure the unit’s CCN communication element number, bus number, and baud rate. Refer to the Linkage Thermostat’s installation instructions for configuring the Stat and additional information about it.
Space Humidistat Control
The humidistat input is provided on the field connection terminal
board. The Space Humidity Switch configuration, Configuration→UNIT→RH.SW, identifies the normally open or normally closed status of this input at LOW humidity. Humidistat 1 terminal is the 24 VAC source for dry contact and the Humidistat 2 terminal is the signal input.
Relative Humidity Sensor Control
For units with the economizer option (with the
CCN Communication
Configure Configuration→CCN→CCN.A to desired element number (Default is 1). Configure Configuration→CCN→ CCN.B to desired bus number (Default is 0). Configure Configuration→CCN→BAUD to desired code number for baud rate (Default is 3 = 9600 baud).
Accessories
Below are quick configuration settings for field installed accessories. If these accessories were installed by the factory, they will already be configured. See the
Economizer
If an Economizer accessory was field installed, the unit must be configured for it by setting Configuration→ECON→EC.EN to YES. The default settings for the other economizer configurations
should be satisfactory. If they need to be changed, additional information about these configuration settings can be found in the Economizer section.
Power Exhaust
If a Power Exhaust accessory was field installed, the unit must be configured for it by setting Configuration→ECON→PE.EN to ENBL. The default settings for the other power exhaust configurations should be satisfactory. If they need to be changed, additional information about these configurations can be found in the Power Exhaust section.
Electric Heat
If an Electric Heat accessory was field installed, the unit must be configured for it by setting Configuration→HEAT→HT.TY to a value of 2. The number of electric heat stages must be configured by setting Configuration→HEAT→N.HTR per the installed heater.
Fire Shutdown
If a Fire Shutdown or Smoke Detector accessory was field installed, the unit must be configured for it by setting Configuration→UNIT→FS.SW to normally open (1) or normally closed (2) when there is not a fire alarm. Normally open (1) is the preferred configuration.
IMPORTANT: On standard units, the fire shutdown input is the terminals Fire Shutdown 1 and 2.
Outdoor Enthalpy
If an Outdoor Enthalpy accessory was field installed, the unit must be configured for it by setting Configuration→ECON→EN.SW, identifies the normally open or normally closed status of this input when the outdoor enthalpy is low.
IAQ Switch
If an IAQ Switch accessory was field installed, the unit must be configured for it by setting Configuration→AIR.Q→II.CF, identifies the normally open or normally closed status of this input when the indoor air quality value is low (good) and also selects the unit response to this input.
IMPORTANT: An IAQ switch cannot be used if an enthalpy switch is already on this input.
IAQ Sensor
If an CO2 Sensor accessory was field installed, the unit must be configured for it by setting Configuration→AIR.Q→IA.CF selects the unit response to this input. Default conversion to 0 to 2000 ppm.
OAQ Sensor
If an Outdoor Air Quality Sensor accessory was field installed, the unit must be configured for it by setting Configuration→AIR.Q →OA.CF selects the unit response to this input. Default conversion to 0 to 2000 ppm.
