WF-EZ3 adjustments and settings – only one setting, selection of the reversing valve logic. See page
10, paragraph 7. The normal/standby switch provides the standard user override function (some power
companies may request deactivation or deletion of this switch, call factory).
Reference "WarmFlo Handheld Analyzer/Laptop Software" section in this manual for changes to your
chip functions.
HPDF Chip Code – Electro-Mate Undersized
Application: 4-wire 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 at 30 minutes
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 all electric to allow total gas operation below ODT temp.
(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
This arrangement provides low temperature interrupt of both the heat pump and the Electro-Mate
elements. If you desire to interrupt only the heat pump, this is the wrong chip code or can be altered with
Handheld.
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-EZ3 adjustments and settings – only one setting, selection of the reversing valve logic. See page
11, paragraph 7. The normal/standby switch provides the standard user override function (some power
companies may request deactivation or deletion of this switch, call factory).
