WF II DIAL SETTINGS
Lower right dial switch – min. warm air – The 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. 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 – The yellow screwdriver
adjustment dial can be set to terminate the heat pump or via special programming can terminate heat
pump and electric to allow total gas operation below ODT temp. (reference manual WF-ANZ*).
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".
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-LGR3 adjustments and settings – The normal/standby switch provides the standard user override
function (some power companies request inactivation or deletion of this switch). No other adjustments or
settings are necessary.
Reference "WarmFlo Handheld Analyzer/Laptop Software" section in this manual for changes to your
chip functions.
HPDF Chip Code – Electro-Mate Undersized
Application: 8-wire standard heat pump thermostat, WF II Electro-Mate, Heat Pump, and gas/oil
furnace using ODT setting as full electric 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
Electro-Mate or strip heat undersizing – there are provisions within WarmFlo and within Electro's
various heating products to add partial resistance heating section to heat pumps. To provide optimum
operation and comfort, the setup functions need to be activated accordingly. Default program code chip
"HPDF" has been designed for this application. As a field setup, you probably want MU to be relatively
short (30 minutes), the ODT mode will be "EL to SB" with a dial switch temperature selection at about
the combination heat pump and Electro-Mate output energy (probably 0°) or position #3.
MU Time – Set to 30 minutes
