chip functions.
Application: 4-wire 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
MU Time = 00 (disabled).
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 – The yellow screwdriver
adjustment dial can be set to terminate heat pump below ODT temp. Electric will stay on until
thermostat is satisfied. Gas will operate only during 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". At no time
can the outdoor compressor built-in ODT and WF II ODT setting (other than 0 = disable) be used
at the same time.
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).
