DIRECT MOUNT ECONOMIZER SEQUENCE OF OPERATION GENERAL This accessory economizer package is designed to save energy costs by using outdoor air for cooling and ventilation in place of mechanical cooling whenever possible. The economizer continuously monitors indoor and outdoor air conditions and compares them to a user-selected setpoint to determine if free cooling is available.
B. Range of adjustment is from 0-100% (2-10V); in most applications the minimum position is adjusted to allow 10% to 25% outside air to enter the system. C. The Outside Air Damper Minimum Position potentiometer can be adjusted at any time. D. Whenever the "G" (supply fan) signal is present, the damper will open to this minimum position unless: a. It may modulate to a greater position if overridden by the CO2 sensor (DCV). b.
C. Economizer Setpoint potentiometer can be adjusted at any time. D. The controller compares the enthalpy sensor input with the economizer setpoint to determine if free cooling is available. a. Single enthalpy strategy: If outdoor air enthalpy is lower than the setpoint, then free cooling is available. Note: The factory-installed 620-ohm resistor must be in place across terminals SR and SR+. b. Dual enthalpy strategy: If outdoor air enthalpy is lower than return air enthalpy, then free cooling is available.
TROUBLESHOOTING 1. Checkout requires a handheld multimeter, 9V battery, a 5.6k ohm ¼ watt resistor, a 1.2k ohm ¼ watt resistor, a jumper wire with ¼" quick connect terminals, and the 620 ohm resistor that is factory-installed across terminals SR+ and SR. The terminal names below reference the economizer controller. Use the following flowcharts for to diagnose unit. 2. a. Disconnect power to the unit. b. Jumper P to P1 (factory installed jumper is normally present). c.

Use the following graph and the multimeter to verify proper operation of the mixed air / discharge air temperature sensor. Measure the resistance (ohms) of the mixed air / discharge air temperature sensor with the multimeter. Look up the equivalent temperature on the graph. This should be the same as temperature the mixed air / discharge air sensor is detecting. If it is not, replace the mixed air /discharge air sensor. NOTES 1.

Recognize this symbol as an indication of Important Safety Information! ! WARNING FURNACES USED ON LP GAS MUST BE EQUIPPED WITH 100% SAFETY SHUT-OFF CONTROLS. CONVERSION WITH THE CORRECT KIT WILL MEET THIS SAFETY REQUIREMENT.
EXAMPLE Serial number on furnace rating plate: 1AD1234AAAAF12340001 CONTROL SYSTEM The first two characters in the serial number are “1A.” When the “1A” is located in Chart I, the control system in the furnace is a Honeywell VR8205 gas valve with United Tech. 1016-452 direct spark ignition control, manufactured to burn natural gas. With the model number from the rating plate, the control system from Chart I, and the type gas it presently burns, the proper conversion kit can now be selected.
USING CONVERSION KIT CHART II STEP 1) Find the appropriate control system by serial number code letters in line 2 of Chart II. STEP 2) Verify the control system listed in line 3 of Chart II by name. Also verify that the furnace actually has this type control system. STEP 3) Identify the furnace model number in lines 4 or 5 in Chart II and move across this line until it intersects the proper serial number column found in step 1. This space shows the proper conversion kit model number.
USING CONVERSION KIT CHART III The following chart should be used to verify the size of all main burner orifices for high altitude derating and natural gas to propane gas conversions. Use the furnace nameplate gas INPUT rating, the number of main burners and the altitude of the installation to select the correct natural gas or propane gas orifice size. The table is based on manifold pressures of 3.5” W.C. for natural gas and 10” W.C. for propane gas.
