Thermostat Heat Anticipation

Set the heat anticipator setting (if adjustable) according to the amp draw listed on the wiring diagram that is attached to the unit.

NOTE: Do not secure the electrical conduit directly to the air ducts or structure.

Electrical

1.Check all wiring for loose connections.

2.Check for the correct voltage at the furnace (furnace operating). Correct voltage is 120VAC ± 10%. 3.Check amp-draw on the blower motor with inner blower panel in place.

Blower Speeds

Follow the steps below to change the blower speeds.

1.Turn off electrical power to furnace.

2.Remove blower access panel.

3.Disconnect existing speed tap at integrated control speed terminal.

NOTE: Termination of any unused motor leads must be insulated.

4.Place unused blower speed tap on integrated control “PARK” terminal or insulate.

5.Refer to blower speed selection chart on unit wiring diagram for desired heating or cooling speed. See Blower performance data beginning on the next page.

6.Connect selected speed tap at integrated control speed terminal.

7.Resecure blower access panel.

8.Turn on electrical power to furnace.

9.Recheck temperature rise.

Electronic Ignition

The integrated control has an added feature of an internal control. The feature serves as an automatic reset device for integrated control lockout caused by ignition failure. This type of lockout is usually due to low gas line pressure. After one hour of continuous thermostat demand for heat, the control will break and remake thermostat demand to the furnace and automatically reset the integrated control to begin the ignition sequence.
