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.

– 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”.
