Integrated Furnace Control

Contains all necessary controls and relays to operate

Combustion air inducer is operated by the integrated furnace control. Prior to ignition, a pre-purge cycle for 15 seconds is initiated. After the main burners are turned off, a post-purge cycle for 5 seconds is run.

Safety Controls - Flame sensor utilizes flame rectification for safe and reliable operation.

Should loss of flame occur, the integrated furnace control will initiate 4 re-attempts at ignition before locking out unit operation for 60 minutes.

Watchguard type circuit automatically resets ignition controls after one hour of continuous thermostat demand after unit lockout, eliminating nuisance calls for service.

Thermostat Control - For optimal performance, the use of a high-quality, digital two-stage thermostat with adjustable settings for first stage/second stage, on/off differentials and adjustable stage timers is recommended.

FEATURES

CONTROLS (continued)

Display LED - Seven segment LED displays alphanumeric information related to diagnostics as well as system operation and status. Diagnostic codes are held in non-volatile memory, immune from power interruptions. Holds up to ten diagnostic codes in order of occurrence for recall on demand. Port on blower door allows for easy viewing.

DIP Switch Settings

Select Thermostat used - Single-Stage or Two-Stage.

Two selectable second stage recognition times (7 and

12 minutes) are available on the control when the furnace is used with a single-stage thermostat. When used with a two-stage thermostat, furnace will only initiate second stage operation with a second stage thermostat demand.

Second Stage Delay - Used with single-stage thermostat only. See Furnace Input Staging Options table for details.

Blower On/Off Time (Heating) - Blower on time is fixed at 30 seconds, blower off time is adjustable from 60, 90,

120 and 180 seconds (factory setting - 90 seconds).

Blower On/Off Time (Cooling) - For air-conditioning applications, blower on time is 2 seconds following thermostat demand for cooling. Blower off time in cooling mode is adjustable from 2 or 45 seconds

(factory setting - 45 sec).

For air-conditioning applications, blower is automatically energized on thermostat demand for cooling.

Heating Speeds - Low Heat or High Heat.

Cooling Speeds - Low Cool or High Cool.

Continuous Speed - Low Heat (factory setting) - adjustable.

Dehumidification - A jumper on the control must be clipped to enable dehumidification. A humidity controlling thermostat or device is also required. During a call for cooling, air volume is automatically reduced, forcing humidity removal by the air conditioner or heat pump system (single stage units or two-stage units running at 2nd stage). After the humidity has reached the desired set-point the cooling air volume returns to its designed rate.

Dual-Fuel Operation - A jumper on the control must be clipped to enable operation with a single or two-stage heat pump. The indoor blower is started without delay when a call for heat is received.

Two Stage Compressor Operation - A jumper on the control must be clipped to enable operation with a twostage compressor.

Accessory Terminal - One accessory terminal furnished for additional power supply requirements for

120 volt (less than 1 amp) powered air cleaners.

One unpowered pair of contacts are provided for humidifier connections and may be connected to 24V or 120V.

Control is factory installed in the unit control box.

HIGH ALTITUDE DERATE

NOTE - Units may be installed at altitudes up to 10,000 ft.

At altitudes above 4501 ft. the unit must be derated to match the manifold pressure information shown below.

Units installed at altitudes of 4501 to 10,000 ft. require a pressure switch change.

Units installed at altitudes of 7501 to 10,000 ft. require an orifice change.

See the Gas Heat Accessories table for ordering information.

NOTE - This is the only permissible derate for these units.

NOTE - In Canada, certification for installations at elevations over 4500 feet is the jurisdiction of local authorities.

NOTE- Optional Side Return Air Filter Kits are not for use with Optional Return Air Base.

Both the unit return air opening and the base return air opening must be covered by a single plenum or IAQ cabinet.

Minimum unit side return air opening dimensions for units requiring 1800 cfm or more of air (W x H): 23 x 11 in. (584 x 279 mm).

The opening can be cut as needed to accommodate plenum or IAQ cabinet while maintaining dimensions shown.

2

Side return air openings must be cut in the field. There are cutting guides stenciled on the cabinet for the side return air opening. The size of the opening must not extend beyond the markings on the furnace cabinet.

To minimize pressure drop, the largest opening height possible, up to 14 in. (356 mm), is preferred.
