ELECTRICAL CONNECTIONS

1.Measure resistance between the neutral (white) connection and one of the burners.

2.Resistance should measure 10 ohms or less.

This furnace is equipped with a blower door interlock switch which interrupts unit voltage when the blower door is opened for servicing. Do not defeat this switch.

24VOLTTHERMOSTATWIRING

IMPORTANT NOTE

WIRE ROUTING MUST NOT INTERFERE WITH CIRCULATOR BLOWER OPERATION, FILTER REMOVAL OR ROUTINE MAINTENANCE.

A REMOVABLE PLUG CONNECTOR IS PROVIDED WITH THE CONTROL TO MAKE THERMOSTAT WIRE CONNECTIONS. THIS PLUG MAY BE REMOVED, WIRE CONNECTIONS MADE TO THE PLUG, AND REPLACED. IT IS STRONGLY RECOMMENDED THAT MULTIPLE WIRES INTO A SINGLE TERMINAL BE TWISTED TOGETHER PRIOR TO INSERTING INTO THE PLUG CONNECTOR. FAILURE TO DO SO MAY RESULT IN INTERMITTENT OPERATION.

As a two-stage non-communicating furnace, the furnace integrated control module provides terminals for both “W1” and “W2”, and “Y1” and “Y2” thermostat connections. This allows the furnace to support the following system applications: ‘Two-Stage Heating Only’, ‘Two-Stage Heating with Single Stage Cooling’, and ‘Two- Stage Heating with Two-Stage Cooling’. Refer to the following fig- ures for proper connections to the integrated control module.

Low voltage connections can be made through either the right or left side panel. Thermostat wiring entrance holes are located in the blower compartment. The following figure shows connections for a “heat/cool system”.

This furnace is equipped with a 40 VAtransformer to facilitate use with most cooling equipment. Consult the wiring diagram, located on the blower compartment door, for further details of 115 Volt and 24 Volt wiring.

NOTE: For single stage cooling applications, a jumper must be located between Y1 and Y2 at the furnace control in order to achieve the desired single stage cooling airflow. Use of ramping profiles and dehumidification features require a jumper between Y1 and O and Y1 and DEHUM, respectively.

NOTE: Thermostat “R” required if outdoor unit is equipped with a Comfort Alert™ module or if the out door unit is a part of the ComfortNet family of equipment AND is wired as a legacy system.

SINGLE-STAGE HEATINGTHERMOSTATAPPLICATION

A single-stage thermostat with only one heating stage may be used to control this furnace. The application of a single-stage thermostat offers a timed transition from low to high fire. The furnace will run on low stage for a fixed period of time before step- ping up to high stage to satisfy the thermostat’s call for heat. The delay period prior to stepping up can be set at either a fixed 5 minute time delay or a load based variable time between 1 and 12 minutes (AUTO mode). If theAUTO mode is selected, the control averages the cycle times of the previous three cycles and uses the average to determine the time to transition from low stage to high stage.
