Digital TEC/Fan Controller  
ATFC106D  
Analog Technologies  
ATFC106D is designed for regulating an enclosed chamber  
temperature by driving a TEC array and a fan array. In  
addition, upon detecting the chamber temperature goes beyond  
the safety windows, see the table below, it cuts off an AC  
power switch by sending the relay control signal. The  
ATFC106D is a digitally controlled TEC/fan assembly  
controller for driving TEC assemblies with fans and  
monitoring the working status at the same time. It allows  
setting the parameters of the set-point temperature window, the  
safety temperature window, monitoring the heat sink hot side  
temperature, heat sink cold side temperature, and the chamber  
temperature, as shown in Figure 2. The controller integrates a  
digital display, a TEC controller, a fan controller, and  
temperature controlled relay control output into one assembly,  
see Figure 3.  
In the controller, there are 2 control loops: TEC and Fan. The  
former has a bi-directional output for achieving both heating  
and cooling effects, the latter switches the fan on and off.

As shown in Figure 4, a digital display is used to show these  
temperatures: Safety High Temperature, Safety Low  
Temperature, Cool On Temperature, Heat On  
Temperature, Satisfied, TEC Outside Temperature, TEC  
Inside Temperature and Chamber Temperature. There are  
8 LEDs indicating which of these temperatures is shown in  
the display.  
The Heat On Temperature, T3, is the temperature point on  
which triggers the TECs to start heating up the chamber air.  
The Safety Low Temperature, T4, is the temperature point  
on which the chamber air temperature gets too low that the  
load control relay is turned off, but the TECs keeps heating  
up the chamber air. There is an option that when the chamber  
temperature gets too low, the load control relay is not turned  
off so that the load is still on and works as a heating element,  
helping increase the chamber temperature.  
The Safety High Temperature, T1, is the temperature point  
on which the chamber air temperature gets too high that the  
load control relay is turned off, but the TECs keep cooling  
down the chamber air.  
The LED indication logic for the above 4 temperatures is  
shown in Table 1.  
The Cool On Temperature, T2, is the temperature point on  
which triggers the TECs to start cooling down the chamber  
air.

There are 2 ARROW keys: ︽ and ︾, for increasing or  
lowering the temperature values when setting the set-point  
temperatures.  
There are 2 LEDs, indicate setting temperature or displaying  
temperature modes respectively.  
The total LED indicating logic is shown in Table 4.  
There is a SET key, to store the displayed temperature into  
the set-point temperature memories in the control software.  
The display can display the temperature from 4°F to 185°F.  
All the buttons, the LEDs, and the display are protected by a  
vinyl face and is of water proof.  
There are 8 temperature parameter indicating LEDs, each is  
dedicated to indicate which of the above 8 temperatures is  
being shown in the display.  
The controller has a metal front plate for panel mounting.  
There is a seal slot so that the mount will be water proof.  
There is 1 LED indicating when the chamber temperature is  
within the normal operating temperature, i.e. T2 > T > T3.  
On the back side of the controller, there are 2 terminal blocks  
with 8 ports and 3 IC ports, see Table 5.
