Configuration Information – Read First
This is an upgrade for the WF-ANZ5, but this unit complies with all WarmFlo units shipped.
- Original board with 28-pin chip
- WarmFlo II board with 40-pin chip
- WarmFlo Plus board with 40-pin chip
- WarmFlo Select board with 40-pin chip
- WarmFlo TS Boiler with 40-pin chip
EB boards include:
EB-WA, EB-WO, EB-MA, EB-MO
EB-S, EB-CA, EB-CO, EB-MS
The analyzer can communicate with different WarmFlo boards. This is done by setting the rotary switch to the board type
you want to communicate with before connecting the analyzer to the board.
NOTE: For the original WarmFlo board with the 28-pin chip, select the ‘Forced-Air’
switch setting.
When the analyzer is connected the display will have “WF-ANZ7” in the top row and the analyzer software version in the
bottom row. After approximately 3 seconds the analyzer will display the type of WarmFlo board the switch is set to for
approximately 3 seconds then “PRESS MON” will appear.
When “PRESS MON” appears, press the ‘MON’ button to continue or if you hold the ‘SHIFT’ key and press the ‘0’ key, the
handheld will read the software version currently in the WarmFlo board connected. The version will stay in the display
until you press any key (except ‘SHIFT’). “PRESS MON” will then re-appear. You can press the ‘MON’ key now to
continue or press ‘SHIFT’ ‘0’ again to read the software version.
If you are connected to a WarmFlo Plus board with software version 10.xx or 12.xx or a WarmFlo Select board (version
18.xx), the configuration switch position will be displayed in parenthesis following the version number.
After the ‘MON’ key is pressed, the analyzer will check the software version against the rotary switch position on the back
of the analyzer. If you are connected to a boiler board and you have the switch in the wrong position the display will show
“SWITCH SETTING” in the top line and the boiler board software version in the bottom line. You must disconnect the
analyzer, change the switch setting and then re-connect.
Because of the different communications protocol between the boiler boards and the forced air boards, the analyzer can
not determine if you have the rotary switch in the forced air position when connected to a boiler board and vice versa. If
the analyzer gets locked up or displays “weird“ numbers then the switch is probably not set correctly.
The boiler boards have a polling scheme for communications, so it will take longer for reading and writing to these boards.
There is an internal timer in the handheld that will display “-----ERROR-----“ if, during monitoring, reading or writing, no
response is received within 10 seconds. To clear the error, press any key (except ‘SHIFT’) to restart the handheld.
If you enter a value that is not within the acceptable range the analyzer will display
“OUT OF RANGE” (on the same line as the bad entry) when you try to write to the board you are connected to.
In addition to the two-line display, the added field programmable functions are shown on the following pages grouped
according to the 3 switch settings.

The keyboard, “SHIFT” is to allow added control functions. Similar to a typewriter keyboard, “SHIFT” refers to the upper
designated key function and must be held down while pressing the other key.
Read Mode:
1) Press and hold the ‘SHIFT’ key, then press the ‘READ’ key to enter the read mode.
2) Pressing 'MON' at any time will go to the real time monitor mode.
3) Use the LEFT and RIGHT arrow keys to move between digits in a field or if a field contains a word choice
use these keys to toggle or change the choice.
4) Use the UP/DOWN arrow key to move between the 2 lines of the display.
5) The 'CLR' key can be used to zero all digits on the display line the cursor is currently on.
This key will not change any word choices.
6) The ‘SHIFT’ + the 'SAVE' key will write the data currently displayed to the WarmFlo board.
When in the MONITOR mode pressing 'MON' again will toggle between 2 displays. Press the 'SHIFT' key plus the 'READ'
key to exit the monitor mode and go into the data entry mode.
If the sensor is not used by the program you will see ‘N/A’ instead of the temperature for that sensor. If the sensor is
detected as bad, you will see ‘BAD’ instead of the temperature for that sensor. This pertains only to the TS Boiler boards
and WarmFlo boards with a 40-pin chip.

Monitor Mode:
1) Pressing 'READ' at any time will go to the data entry or read mode.
2) Use the 'MON' key to toggle between the 2 displays.
3) The displayed data is automatically updated every 7 seconds.
While in the monitor mode you can also hold the ‘SHIFT’ key and press ‘9’ to get to the CFM setup (see page 9).
The monitor mode data consists of:
OUTDOOR (Outdoor Temperature, OT)
SUPPLY (Supply Temperature, ST)
DESIRED (Desired Temperature, DT)
PWM RATIO
Within the WarmFlo operating module DT is calculated based upon the "Min. Warm Air" switch setting and/or the heat loss
curve built into the software. This heat loss curve takes the same shape as a typical building heat loss plot. The curve's slope
or point-by-point relationship between OT and ST is determined by specific WarmFlo chip codes or by the setting of the center
"Temperature" switch. In other words, this either represents "min. warm air" for mid or higher outdoor temperatures or the slope
(heat loss) for the lower OT values requiring DT above the "min. warm air". Thus DT is the delivery temperature required to
"heat the house" at a specific outdoor temperature.
PWM Ratio is the percentage of time stage 1 output is on. As the ST gets closer to the DT the PWM Ratio will decrease.
OT and ST (Outdoor and Supply Temperature)
(OT and ST Offset Entry)
Enter an offset to be added or subtracted from the OT and ST temperatures read from the sensors. Use the '–' key to enter an
offset to be subtracted from the sensor reading.
MU TIME
(Makeup Time)
(Enter 0-99 minutes)
An entry of 00 disables the timer.
The make up timer starts counting down when all electric stages are full on (PWM = 100%) and ST (Supply Temperature) is
less than DT (Desired Temperature) by more than 2°F. When the timer reaches 0 the board will go into the standby mode until
the Y input is removed.
SB RESET
(Standby Reset)
(Select Enable or Disable)
When the WarmFlo board goes into a standby mode, it sets a timer for 5 minutes. After this timer has expired, it checks the ST
temperature. If the ST temperature is less than 80°F, the unit will reset itself. Select ‘Enable’ if you want the board to do this
and ‘Disable’ if you do not want the board to reset.
NOTE: Unless the WarmFlo board has software version 2.21 or greater the disable function will be ignored.
It will always be enabled.
SOT-S TIME
(Enter 0-99 minutes)
An entry of 00 disables the timer.
This timer starts counting down at the beginning of heat active. If the timer reaches 0 during a continuous heat active cycle, the
board will go into the standby mode until the Y input is removed.
If both SOT-S and SOT-E times are used, SOT-S time should be greater than SOT-E time.
SOT-E TIME
(Enter 0-99 minutes)
An entry of 00 disables the timer.
This timer starts counting down at the beginning of heat active. If the timer reaches 0 during a continuous heat active cycle, the
board will default to a flat DT/HL until the Y input is removed.
If both SOT-S and SOT-E times are used, SOT-E time should be less than SOT-S time.
(See the definition of Flat under the OT Sensor Function below.)

04/24/2009 7 HI010
STG 1-4 OT DIS
(Stage 1-4 OT Disable Temperature)
(Enter a temperature within the range of -40°F to +185°F)
The OT sensor is used to determine summer or air conditioning function and keeps the electric elements and stand-by off even
though there may be a Y input.
Whenever the OT is greater than or equal to the entered value the stage is kept off.
OT FUNC
(OT Sensor Function)
Note: If V10.xx, V12.xx or V18.xx ‘DT CAL’ or ‘DISABLE’ will be displayed and cannot be changed.
Select from 3 choices: DT CAL, FLAT or DISABLE.
DT CAL
OT sensor will be read and its reading will be used to calculate DT.
FLAT
(Flat DT/HL)
Any heat call will step-up to a flat DT/HL (High Limit temperature).
In other words the high limit temperature will become the DT.
(The OT sensor will still be read but its reading will not be used.)
DISABLE
Electronic Aquastat mode.
The OT sensor is not read.
When changing TO this mode from one of the other 2 modes, or when changing FROM this mode to one of the other 2
modes, you must cycle power on the WarmFlo board.
ODT SW
(ODT Switch Mode)
Select from 3 choices: EL TO SB, HP ODT or HP W/STEP.
EL TO SB
If OT is less than the ODT dial switch setting, the board will go into the standby mode.
HP ODT
(HP ODT Only)
If OT is less than the ODT dial switch setting, the HP-ODT interrupt is activated.
HP W/STEP
(HP ODT With Step-Up)
Same as "HP ODT" plus the stages step-up to a flat DT/HL.
OT SPD A and B
ST SPD A and B
(Software version 2.30 and greater only)
Note:If V10.xx or 12.xx, OT SPD A and ST SPD A will display ‘N/A’ and cannot be changed.
(Enter a temperature within the range of -40°F to +185°F)
During heat active (including E), non-standby, SPD A and/or SPD B outputs are turned on if OT is less than
the temperature values for SPD A and/or B.
Once on, the outputs are left on until the end of the heat cycle.
During heat active (including E), non-standby, SPD A and/or SPD B outputs are turned on if ST is greater than
the temperature values for SPD A and/or B.
Once on, the outputs are left on until the end of the heat cycle.
ST check is done only after 30 seconds after the start of a heat cycle.
This only applies to Dual Heat I/F modules plugged into J2 (full 10 pin cable).
The temperature entered can control the furnace or air handler blower speed.
NOTE: WarmFlo Plus and WarmFlo Select have OT/ST SPD B output (tab connection)

CT STG DISABLE
(Software version 10.xx, 12.xx or 18.xx only)
(Enter 0, 1, 2, 3 or 4)
Enter one or two stage numbers to disable when the CT input senses 10 amps or more.
These stages will turn OFF immediately.
When the CT input senses 5 amps or less, the stages will be re-enabled and come back ON if necessary.
If no stages are to be disabled, enter ‘0’.
When a CT input of 10 amps or more is sensed, a 30 second timer is started and the stages entered are disabled. The CT input
is now ignored until the timer expires and then the input is read again and if still active the timer restarts and the input is again
ignored for 30 seconds. This continues until the CT input senses 5 amps or less, then the input is continuously read until 10
amps or more is sensed and the timer starts again.

TS Boiler EB-S EB-CA EB-CO EB-MS
04/24/2009 10 HI010
Note: TS Boiler EB-S and EB-CA models do not use the outdoor sensor so the temperature displayed
for “OUTDOOR” will read “N/A”.
Monitor Mode:
1) Pressing 'READ' at any time will go to the data entry or read mode.
2) Use the 'MON' key to toggle between the 2 displays.
3) The displayed data is automatically updated every 5 seconds.
The monitor mode data consists of:
OUTDOOR (Outdoor Temperature, OT)
WATER (Water Temperature, WT)
SET POINT (Set Point Temperature)
For models EB-S, EB-CA and EB-MS:
The Set Point Temperature is determined by the position of the temperature selector switch on the boiler’s front panel.
For model EB-CO:
Within the TS Boiler operating module, SET POINT is calculated based upon the heat loss curve built into the software.
This heat loss curve takes the same shape as a typical building heat loss plot. The curve's slope or point-by-point
relationship between OT and WT is determined by the setting of the "Temperature Selection" switch on the front of the
boiler. This dial switch allows field selection of 8 “curve slopes”. The setting reference point is the controlled outlet
temperature (WT) at 0°F outside. Thus SET POINT is the delivery temperature required to "heat the house" at a specific
outdoor temperature.
OT and WT (Outdoor and Water Temperature)
(OT and WT Offset Entry)
Enter an offset to be added or subtracted from the OT and WT temperatures read from the sensors. Use the '–' key to enter an
offset to be subtracted from the sensor reading.
* DELAY E HI MASS
(Enter 0 to 9 minutes)
Every ‘Delay E’ cycle the WT temperature is compared to the set point temperature to determine if any more or any less stages
should be on. The set point switch settings that are ‘Hi Mass’ are positions 0 thru 4.

TS Boiler EB-S EB-CA EB-CO EB-MS
04/24/2009 11 HI010
* DELAY E LO MASS
(Enter 0 to 9 minutes)
Same as ‘Delay E Hi Mass’ except the set point switch settings for ‘Lo Mass’ are positions 5 thru 7.
* START UP DELAY
(Enter 0 to 99 seconds)
This is the delay at the beginning of a ‘W’ heat call before determining whether or not any stages should be turned on.
* Typically these are factory only settings.
