Carrier 33CSPREMLK Supply Air Temperature Display Units, Control Set Point Display Units

To access the sub-mode to change the Unoccupied OAT Lockout Setpoint, press the down arrow to scroll down until the Navigator™ module display reads:

SETP

OATL >NTLO

UHDB

To view an expansion of the sub-mode, press the ENTER

and ESCAPE keys simultaneously and the Navigator will

display:

>NTLO

UNOCC. OAT LOCKOUT TEMP

The Navigator will remain in the expanded display mode

until the ESCAPE key is pressed. Use the arrow keys to view

expansions for any of the other sub-modes within the Setpoint mode.

Password Protection — If an area is entered that is password protected or an item is selected for change that is password protected, the Navigator will display:

Enter Password

1111 (default password)

The first digit of the password will be flashing. Hold either of the arrow keys down to change the value of the first digit (if

necessary) and press ENTER to accept. Repeat the process for

the remaining three digits.

The message “Invalid Password” is displayed if the pass- word is not correct. The password can not be disabled from the Navigator, nor can it be changed.

Forcing Values and Configuring Items — Cer- tain items are allowed to be forced and other items are user- configurable. Both of these changes can be made using the Navigator.

CONFIGURATION

The following sections describe the computer configuration screens which are used to configure the PremierLink™ con- troller. The screens shown may be displayed differently when using different Carrier software.

Points Display Screen — The Points Display screen is used to monitor and change the PremierLink controller set points. See Table 7.

SPACE TEMPERATURE — This point displays the space temperature from the 10K thermistor (Type III) located in the space.

Space
Temperature:	Display Units:	Degrees F (Degrees C)
	Default Value:	–40.0
	Display Range:	–40.0 to 245.0
	Network Access:	Read/Write

SUPPLY AIR TEMPERATURE — The Supply Air Temper- ature point displays the temperature of the air leaving the unit, downstream of any cool or heat sources. Temperature is mea- sured by a 10K thermistor (Type III). This sensor is required for proper function of the heating, cooling, and the economizer.

Supply Air
Temperature:	Display Units:	Degrees F (Degrees C)
	Default Value:	0.0
	Display Range:	–40.0 to 245.0
	Network Access:	Read/Write

OUTDOOR AIR TEMPERATURE — Temperature of the air leaving the unit downstream of any cool or heat sources, measured by a 10K thermistor (Type III). This sensor is required for proper function of the heating, cooling, and the economizer.

Outdoor Air
Temperature:	Display Units:	Degrees F (Degrees C)
	Default Value:	0.0
	Display Range:	–40.0 to 245.0
	Network Access:	Read/Write

CONTROL SET POINT — This point displays the current controlling set point when a heat or cool mode is active. If there is not an active heat or cool set point, the set point of the last mode is displayed. Upon reset or start-up, the proper cooling set point is displayed, depending on occupancy. In the thermo- stat mode, this point is not used for equipment control.

Control Set Point: Display Units:	Degrees F (Degrees C)
Default Value:	Unoccupied Cool
	Setpoint
Display Range:	35 to 110
Network Access:	Read Only

COOLING PERCENT TOTAL CAPACITY — The Cooling Percent Total Capacity point is used to display the current Cooling Capacity. When cooling is enabled, the percent of cooling being delivered is determined by the following formula for the number of compressor stages confirmed:

% Output Capacity = (# of active stages/Total stages) * 100.

Cooling Percent
Total Capacity: Display Units:	% output capacity
Default Value:	0
Display Range:	0 to 100
Network Access:	Read Only

HEATING PERCENT TOTAL CAPACITY — The Heating Percent Total Capacity point is used to display the current Heating Capacity.

When heat is enabled, the percent of heat being delivered is determined by the following formula for electric heat:

% Output Capacity = (# of active stages/Total stages) * 100

Heating Percent
Total Capacity: Display Units:	% output capacity
Default Value:	0
Display Range:	0 to 100
Network Access:	Read Only

ECONOMIZER ACTIVE — The Economizer Active point displays the status of the economizer for free cooling. When the outdoor conditions match the desired indoor conditions, the economizer will be enabled for outdoor air assisted cooling.

Active: Display Units: Discrete ASCII Default Value: No

Display Range: No/Yes

Network Access: Read Only

SUPPLY FAN RELAY — This point displays the command- ed state of the Supply Fan Relay.

Supply Fan

Relay: Display Units: Discrete ASCII Default Value: Off
