Temperature (Efficiency Dial) – Located on the front cover of the WF II Electro-Mate, the red center
screwdriver adjustment dial has a selection of A through G. 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 or the higher the operating efficiency. The closer a selected setting is to G, the steeper the
heat loss curve or the lower overall heat pump system efficiency. If knob is turned to "full" the WF II
will automatically go to "DT flat".
WF-LGR4 adjustments and settings – The normal/standby switch provides the standard user override
function (some power companies request inactivation or deletion of this switch).
Requires selection of the proper RV logic at the LGR4 board top center, see previous page.
Reference "WarmFlo Handheld Analyzer/Laptop Software" section in this manual for changes to your
chip functions.
The primary intent for this default arrangement is total electric heat pump without standby gas/oil furnace.
However, there are some specific dual heat applications where HPEL could apply.
1. On a temporary basis gas furnace is not operative.
2. Gas/oil furnace is intended or used only during load control function.
Application: 8-wire standard heat pump thermostat, WF II Electro-Mate, Heat Pump, and gas/oil
furnace. This code will only allow gas/oil on during utility control – The WarmFlo II controller with
this chip has outside temperature reference for enabling the electric heat staging (except "E" tab). The
outside temperature (actual sensor) must be below these values before the stage will come on,
independent of supply sensor requirement.
Stage 1 = 5Ø°F

WF II DIAL SETTINGS
Lower right dial switch – min. warm air – This is the screwdriver adjust which 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. Reference manual "heat loss curve graph".
0 = 90
1 = 92
2 = 94
3 = 96
Top right dial switch - Built-in ODT or Low Temperature Switch-Over – This is the screwdriver
adjustment dial that can be set to terminate heat pump below ODT temp. The only time gas will be
used is in utility control (reference manual WF-ANZ* for special programming).
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
COMMENT: If you are using outdoor compressor built-in ODT, set the dial to "0".
