Setup or Programming
It is extremely important the installer properly sets the peg jumpers for all of the following requirements.
WarmFlo Controller –
Inside View, Left Board
Program Control Chip – AHS Chip Code
This unit is provided with a control chip (version 2.36 or higher) which can relate to non-heat pump, only
ST sensors installed. The key information is programmed within this “AHS” chip.
Warm Air Dial Settings
Lower right
dial switch
–
min. warm air
– The yellow dial switch sets the operating temperature.
0 = 100
4 = 116
Factory set on #3.
1 = 104
5 = 119
2 = 108
6 = 122
3 = 112
7 = 124
Program Control Chip – WFMU Chip Code
This unit is provided with a control chip (version 2.36 or higher) which can relate to make-up air, only ST
sensors installed. The key information is programmed within this “WFMU” chip.
Warm Air Dial Settings

Electric Furnace Control –
Inside View, Right Board
Room Thermostat Type
On the control board left side is a peg jumper which, based on application, this jumper must be set
accordingly.
• Forced air space heating application (AHS): Set to conventional heat/cool.
• Make-Up Air application (WFMU): Set to “HP”
Heat Minimal Blower Speed Selection
On the right side is a peg jumper for a LO/MED/HI selection. As an ST sensor only model, this setting
must match the kW.
10 kW LO 765 CFM
15 kW MED 900 CFM
20 kW HI 1035 CFM
Cool Minimal Blower Speed Selection
At the control board right side is A/B/C/D selection. It is very important that this selection be matched to
the cooling ton installed within the system. This is independent of the heating as outlined and setup
above.
A – 3-3.5 ton 1200 CFM
B – 2.5-3 ton 1100 CFM
C – 2-2.5 ton 1000 CFM
D – 2 ton 900 CFM
Note: “COOL” section is used in
make-up air
applications with default in A.
