CONTROLLER SETUP OR PROGRAMMING

Important - Located on the WF II board is a firmware chip that determines a specific set of defaults. This can
also be programmed (altered) with optional PC software (ET-SOFT-WF) or a plug-in WarmFlo analyzer (WF-
ANZ*). As part of the WF II system this chip represents critical defaults and settings that make your system
operate correctly.
This application, as outlined on the cover page, is supplied with "HPEL". Other chip codes are available, or
can be field reprogrammed, see Handheld Analyzer section.
The factory default setup of the WarmFlo II module is detailed below:

Electric staging enable – Stage 1 = 50°F, 2 = 38°F, 3 = 36°F, 4 = 34°F

MU time – set as disable

ODT mode – HP ODT

SOT S time – disabled

SOT E time – disabled

OT sensor function – DT cal.
NOTE: If these factory defaults do not meet your application, reference HD320 for more options.
Dial Settings
Left 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 later section "heat loss curve".
0 = 90
1 = 92
2 = 94
3 = 96
Right dial switch - built-in compressor ODT – The yellow screwdriver adjustment dial can be set to
terminate the heat pump (reference manual WF-ANZ*).
NOTE: Requires added relay to open yellow wire, see Electrical Hookup section.
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".
