ECT-100 Temperature Controller
Version 1.4 (Oct, 2017)
1. Overview
This is an economical plug-n-play controller that can be used for Sous Vide
cooking, and other low temperature control applications (<221° F or 105° C). It
offers PID mode for heating control, as well as on/off control mode for either
heating or cooling. The PID mode is suitable for precision temperature control
such as Sous Vide cooking. The on/off control is suited for controlling devices
that does not like to be switched on/off too frequently such as the compressor
of the refrigerator.
This controller has a temperature sensor comes with it, which can measure
temperature in the range of -50 ~ 120° C (-58 ~ 248° F). The power input can be
either 120V AC or 240V AC. The output power will be supplied to the output
socket, to which a load can be plugged. The output power is controlled by an
internal electromechanical relay whose action synchronize with the OUT
indicator on the front panel. The output voltage is the same as the input voltage.

4. Temperature Setup
To change its preset temperature: Press SET key once to switch the display
from actual temperature to set temperature. The display will start to blink.
Press Up and Down keys to increase or decrease the setting temperature.
When finished, press SET key once to confirm and exit.
Note:
Parameter remains unchanged unless you press set key to confirm.
5. Parameter Setup
To enter parameter setting mode, press and hold SET key for 6s and it will
show
