WF II DIAL SETTINGS
Lower right dial switch – min. warm air – The lower inside yellow screwdriver adjustment dial sets a
"floor" or level minimum operating temperature. The supply temperature will never go below this point
independent of outdoor temperature. In other words, this is the flat horizontal line on the warm air versus
outdoor temperature curve referenced in this manual "Heat Loss Curve" graph.
Upper right dial switch – built-in ODT or Low Temperature Switch-Over – The "ODT" yellow
screwdriver adjustment dial can be set to terminate the Electro-Mate for low outdoor temp. gas/oil
operation. For outside temperatures below this set value, the gas furnace is used for all heat call cycles
and requirements. Comment: Typically this is used for undersized Electro-Mate.
The temperature settings related to the "ODT dial" are:
Ø = Disabled, no ODT switch-over
1 = -15°F
2 = -10°F
3 = 0°F
4 = 5°F
Front control red dial - Temperature (Efficiency Dial) – Located on the front door of the main WF II
cabinet. The small red adjustment screw is active and needs to be set. Verify the outdoor sensor (OT) is
installed. These A through G selections represent a supply temperature point at 0° outdoor. The closer
the user or installer selection is to A, the flatter the heat loss curve and the lesser the operating electric.
The closer a selected setting is to G, the steeper the heat loss curve and more operating electric.
Reference WarmFlo Operation Information section on heat loss curve for further information. Setting the
dial to full electric will bring on all stages of electric at full capacity.
Reference "WarmFlo Handheld Analyzer/Laptop Software" section in this manual for changes to your
chip functions.
Electro-Mate, Non-Heat Pump, using EMR type program chip code – The outdoor sensor is used as a
staging disable function. With a call for heat the desire temperature attempts to rise to "flat DT" (desired
temperature). With this chip code the number of stages is limited by the enable temperature reflected
below.
Stage 1 = 90°F
MU Time – 00 (disabled)
