HANDHELD ANALYZER/LAPTOP SOFTWARE
PC software (ET-SOFT-WF) or Handheld (WF-ANZ*) – has provisions for the following
setup or reprogramming functions. Caution – do not attempt to reprogram a forced air (Electro-
Mate) chip for boiler application.
- Select proper product application – dial switch on the back
- MU time, or disable
- SB RESET – disable/enable
- SOT S time, or disable – switches to standby
- SOT E time, or disable – all stages on
- Stage disable temperature – 1, 2, 3, 4
- OT sensor function
·
DT cal.
·
Flat DT or HL (suggest not using)
·
Disable
- ODT dial switch mode
·
EL to SB – interrupt all electric energy (Electro-Mate and HP)
·
HP – Outdoor compressor interrupt only
- OT SPD A/B and ST SPD A/B – special temperature sensing speed settings, relates
only to variable speed motor interface arrangements (WF-ANZ5 and up)
- WF-ANZ7 adds a EB-WO or EB-MO function for establishing the baseline or
beginning point for modulation temperature ramp-on
Warning, field reprogramming – within WarmFlo II internal logic and non-volatile memory, it
can detect whether it is operating from a pre-programmed chip (see table, following pages) or if it
has been modified (reprogrammed) with PC software or Handheld. Once the user or field
technician has downloaded (save), the WarmFlo II physical control board is no longer governed
by the chip code written on the plug-in chip, etc. In other words, power up/power down or reset
does not affect any altered reprogrammed functions. It is smart enough to know it is no longer
the original chip and that specific physical board, from this time forward, must be under the
control of the PC software/Handheld.
However, a new totally different coded chip with the same or different revision date will
automatically wipe out any of the previous setups and can restart the same physical board based
on the defaults within this newly added or different coded chip. After power-up reset the internal
program reads the chip code and the version number. If either changes it begins new with the
defaults and revision code of the specific replaced chip.
In order for the installer to completely understand the WarmFlo II functions and operational
sequence it is recommended to thoroughly read and understand the information below. This
knowledge can help in determining settings that can be set according to the end customers needs.
Normal Heating Operation – Whenever the WarmFlo II Y tab is at 24 volt (with reference to
"C"), the WarmFlo II controller begins turning on the Electro-Mate elements (assume outdoor
temperature is below disable value) and automatically controls the warm air temperature as
sampled by the warm air sensor (ST). However, if added heat is not required, no element power
is used.
Depending upon Electro-Mate model, the heating section may have one, two, three, or four
stages. Stage one is pulse modulated (approximate 10-second cycle) based upon the WarmFlo II
controller automatic requirement. Stages 2, 3, and 4 are turned on and off with a relay. However,
Stage 2, etc. is only used when needed by the WarmFlo II supply air temperature calculations.
