B5 Dehumidify:ON/OFF

Input Status:Open

THIS SCREEN DISPLAYS THE STATUS OF THE DEHUMIDIFICATION MODE.

This screen only appears if there is a humidistat wired to terminals B5 and BC5 on

the controller.

When the Input Status is Open, there is no call for dehumidification. When the Input

Status is Closed, the cold-coil set point is reset for further dehumidification.

ANALOG OUTPUTS - PARAMETERS

The Analog Output screens allow the user to adjust the analog outputs for the energy recovery wheel, heating, cooling, and

hot gas reheat operation. The factory defaults are provided in the screens shown and are designed to operate with any

factory supplied components. Chilled water valves, hot water valves, DX distributors, or HGRH valves provided by others

may require adjustments to the following screens to properly operate the components.

Analog output Y1

Energy Recovery Wheel

Output 0% --> 100%

SIGNAL 00.0V 10.0V

THIS SCREEN DISPLAYS THE CORRELATION BETWEEN THE ANALOG OUTPUT %

AND THE VOLTAGE SIGNAL FOR THE ENERGY RECOVERY WHEEL.

***DO NOT ADJUST THIS SETTING***

This screen may relate to on/off or modulating control depending upon what

accessories were ordered with the unit. The energy recovery wheel is factory-installed

and programmed.

Analog output Y2

Heater

Output 0% --> 100%

SIGNAL 00.0V 10.0V

THIS SCREEN DISPLAYS THE CORRELATION BETWEEN THE ANALOG OUTPUT %

AND THE VOLTAGE SIGNAL FOR THE HEATING (IE. 60% = 6 VDC).

This screen only appears if Heating was provided with the unit.

The Output and SIGNAL will provide the appropriate control of a hot water coil, electric

heater, or indirect gas furnace. User can change the SIGNAL range if required. Factory

defaults are 0-10 VDC.

NOTE: This is where the user would adjust for a Heating Control Valve that is

2-10 VDC rather than 0-10 VDC.

Analog output Y3

Cooling

Output 0% --> 100%

SIGNAL 00.0V 10.0V

THIS SCREEN DISPLAYS THE CORRELATION BETWEEN THE ANALOG OUTPUT %

AND THE VOLTAGE SIGNAL FOR THE HEATING (IE. 60% = 6 VDC).

This screen only appears if Chilled Water was provided with the unit.

The Output and SIGNAL will provide the appropriate control of a chilled water coil.

User can change the SIGNAL range if required. Factory defaults are 0-10 VDC.

NOTE: This is where the user would adjust for a Cooling Control Valve that is

2-10 VDC rather than 0-10 VDC.

Analog output Y4

Hot Gas Reheat

Output 0% --> 100%

SIGNAL 00.0V 10.0V

THIS SCREEN DISPLAYS THE CORRELATION BETWEEN THE ANALOG OUTPUT %

AND THE VOLTAGE SIGNAL FOR THE HOT GAS REHEAT (IE. 60% = 6 VDC).

This screen only appears if HGRH was provided with the unit.

The Output and SIGNAL will provide the appropriate control of a on/off or modulating

hot gas reheat coil. User can change the SIGNAL range if required. Factory defaults are

0-10 VDC.

DIGITAL INPUTS - PARAMETERS

Digital Input (ID1)

Supply proving switch

Alarm: Open

Status:Closed

THIS SCREEN DISPLAYS THE ALARM STATUS MODE OF THE SUPPLY PROVING

SWITCH.

When the Supply proving switch alarm is triggered, the fan is not seeing airflow and the

unit will shutdown and alarm. The Alarm parameter allows the user to select Open or

Closed for the contact position that will trigger the alarm. Status displays the real time

status (Open/Closed) of the digital input.

NOTE: The controller is only monitoring the contact position -- Not the actual

operation of the fan.

I/O SETUP MENU - continued

WARNING!

The following screens show the factory defaults for each parameter. Do NOT change parameters unless you are

absolutely certain the parameter needs to be modified. Unit will not function properly and damage may occur

to the unit if the parameters do not match the contact requirements of the components.
