50F06-843 Universal Furnace Electronic Fan Timer
Product Launch – Fall 2019

Introducing WHITE-ROGERS Newest Universal Replacement Control
A Non-Integrated Control Board that utilizes an internal timer to turn the Furnace Blower Fan on through a timing sequence rather than a temperature sensing device.
Blower functions that are completed through an electronic timer on the Board are:
Heat Fan Speed
Cool Fan Speed
Continuous Fan Circulation Speed
The 50F06-843 can also initiate the Inducer Fan and monitor Furnace operation*
*Note: Level of control depends upon model being replaced.
Easy to Install, Easy to Configure, Easy to Diagnose

Non-Integrated Furnace Electronic Fan Timer
What is “Non-Integrated”?
A Non-Integrated Control is a partial control that connects to another for complete operation.
The 50F06-843 will Integrate with any one of these 3 types of Ignition Controls for complete Furnace operation:
Direct Spark Ignition Control
Hot Surface Ignition Control
Intelligent Gas Valve Control
The Timer controls the Fan Blower while providing Safety Circuits* to monitor Pressure Switch Safeties, Temperature Limit Safeties, Blower Failure, and Voltage Fluctuations.
*Note: Level of features depends upon model
being replaced.

Fan Timer History
Era of Fan Timer Controls Manufactured in Furnaces
ICP produced >2M furnaces
from 1994 to 2006. During this
period they manufactured
Furnaces using a Fan Timer
Control and SmartValve™ .
1935 1968 1988 1990 2006
Mechanical
temperature switches
are used to control
when the blower
turns on/off.
Hamilton Standard
Controls, Inc. – A
division of UTC,
patents a Furnace
Blower Control that
uses a microprocessor
to time the fan blower
on & off instead of a
temperature sensing
control.
An electric fan to
distribute the heated
air through ductwork of a coal fired furnace
within the home is
patented.
A fully Integrated
Furnace control that
controls the gas valve,
gas ignition, flame
sensing, blower fan
operation, induced
draft sensing, & limit
functions is patented
by Hamilton Standard
Controls, Inc.
Furnaces with non-
integraded controls no
longer manufactured
Fenwal introduces an
Intermittent Spark
ignition system to
replace Standing Pilot
Systems. Other
companies follow
over the next couple
of years.

Universal Fan Timer Application
Where all can this be
used?
The 50F06-843 has been cross to over 150 board numbers.
References are listed on the outside of the box packaging.
White-Rodgers gives you
over 150 cross-references
compared to Brand X
which only list 48
6
Easy to Install Mounting Options
The raised molded
base provides space between board and unit mounting plate.
6 mounting holes
designed to match the board being replaced give multiple options for alternate mounting.
Mounting screws are
provided for multiple options.
4x ¼”x1”, and 2x
¼”x½”
We match mounting holes
of existing boards that are
not matched by other
brand replacements.
7
Multiple ID Terminal Labels
On some Terminals
multiple identifiers are Silkscreened on the board. All cross-over boards are identified and referenced on each Terminal, making it easy for correct placement of wires.
Only White-Rodgers gives
all previous version
Terminal Identifier Labels
8
2 Sizes of 24v Power Connections
X1/24VAC/X has both ¼” & ³∕₁₆” Terminal
Connectors
For 24v Secondary input from 24v Transformer.
C/COM has both ¼” & ³∕₁₆” Terminal Connectors
For 24v Common input from 24v Transformer.
Some older systems still have ³∕₁₆” spade connectors
on wires from the Transformer to connect to the Board.
The 50F06-843 has these ³∕₁₆” terminals so the
existing wire Spades don’t have to be replaced.
Only White-Rodgers gives you both Spade
Terminal size options to connect the
existing Transformer Connector wiring.
9
24v Transformer Extension Wires Included
Some older systems have the 24v Transformer located so that the 24v wires will not reach the 24v input Terminals on the Fan Timer.
Additional ¼” x ¼” Spade Extension Wires are
included for Transformers located farther from the Control mounting location.
Only White-Rodgers gives you 2 Wire
Extensions with Spade Connectors to easily
connect the existing Transformer wiring.
Also included are a pair of ³∕₁₆
Insulated Spade Terminals for adapting the Extension wires.
10
Blower Speed Output Terminals for any Application
HEAT: Once the Fan timer completes the Blower
Heat-On Delay, the HEAT & ACC are powered.
COOL: Once the Fan timer completes the Blower
Cool-On Delay, the COOL & ACC are powered.
ACC: Powered anytime the HEAT or COOL is
energized.
EAC: Powered anytime HEAT or COOL is energized.
CONT: Powered when the Fan Control Board is
powered up and designed to power 24/7. Is De­energized when HEAT or COOL is powered.*
*Note: An Electronic Air Cleaner requires direct 115v power 24/7
when connecting the blower to the CONT terminal in order for it to be constantly on with the blower.
Only White-Rodgers gives you an ACC Terminal
that is powered during both Heat & Cool calls
for single Blower speed applications.
11
Additional Unused Blower Motor Lead / Park Terminals
M1/M2/M3/UNUSED: 3 Terminals are provided
to park / place unused Blower leads.
These Terminals allow unused Blower Motor
wires that are different speeds to be “parked”
without cutting off the Spade connector in case that Blower speed needs to be used and a different one parked.
White-Rodgers gives you 3
Unused Terminals compared to
Brand X which only has 2.
12
Adjustable Fan Delays & Options w/ Dipswitch Functions
Board has 2 sets of Dipswitches:
SW1 – 4 functioning SW2 – 2 functioning, 2 unused
Only White-Rodgers gives
you a Dipswitch to
customize the “G” Blower
speed to operate either on
the Heat or Cool speeds.
A screwdriver can be used to change settings through protective Dipswitch cover.
13
All 115v/230v Power Connections on one end of Board
L1/S/S1-S3 has 2x ¼” Connectors
115v Hot / L1-230v input from
power source.
115v Hot / L1-230v output to 24v
Transformer.
Neutral has 7x ¼” Connectors
115v Neutral / L2-230v* input from
power source
L2-230v* / 115v Neutral output to
24v Transformer
L2-230v* / 115v Neutral for
additional 115/230v* circuits (Inducer Fan, Blower Fan, EAC, Humidifier)
*See Manufactures Equipment Wiring
Diagram for correct voltage wiring.
White-Rodgers gives you 7
Neutral Terminals compared to
Brand X which only has 6.
14
Simplified Connection Wiring Harnesses w/ ID Flags
Port E38 is used
for 2ndgeneration SmartValves (ST9160 Boards).
Using Port 38
requires a ST9160 Jumper installed on Port J1.
Port J1 is used for
1stGeneration SmartValves or Non-Integrated Ignition Controls.
Additional wiring
harnesses are provided for various applications.

ST9101
ST9141
ST9160
The ST9120 replacement does not
require any additional wiring harnesses.
15
Duplicate “Y” & “C” 24v Terminal Connections
The 24v Terminal Block has 5 standard
connections:
“C”, “G”, “Y”, “W”, & ”R”
Additional 24v “Y” & “C” spade terminals are internally
connected on the bottom of the board. This allows for easy connection to the cooling Contactor in some applications.
White-Rodgers gives you both screw
and spade Terminal connections for
cooling control wiring.
16
Fan Blower Twinning Feature
Two 50F06-843 Fan Timer Boards
can be connected to operate the Fan Circulator Blowers simultaneously.
Twinning only requires a
connection of the Twin/Z1/Z2 Terminal on both boards using an 18ga wire.
The Board with the Thermostat
connection will fully function including the LED indicator and Dipswitch settings. The Twinned Board will operate the blower only simultaneously (LED will show standby) as determined by wired
board unless “W” or “Y” are
powered to it.
The Twinned unit can be wired for
Heat to come on by utilizing the
“W” terminal either with the 1
st
unit
or as a 2ndstage.
If both Boards are not powered
a Twinning fault of 6 red flashes occurs.
