: Always disconnect power sources before wiring or servicing.
The module needs its own 12V power supply (on the VCC/GND terminals) plus the load power. The relay is just a switch; it does not convert voltage.
: Dual display showing Measured Value ( PV ) in red and Set Value ( SV ) in green.
Displays target temperature (Set Value). SET Key: Used to change parameter settings. AT Light: Lights up when Auto-Tuning is in progress. sinotimer mc101 manual
: Supports both precise PID control and standard ON/OFF modes.
Shifts the active editing digit to the left when modifying values. It also acts as an Auto/Manual switch in certain modes. Down Arrow Button: Decreases the numerical value. Up Arrow Button: Increases the numerical value. 4. Quick Start: Setting the Target Temperature (SV)
The system needs to be auto-tuned. Run the AT function, or increase your P and D variables manually. : Always disconnect power sources before wiring or servicing
Connect your 85–265V AC main power lines here. Control Output (Terminals 3, 4 & 5):
Connect to pins for AC/DC power (check label for voltage, usually 85–265V). Input (Sensor):
: Connect to the designated input terminals (often terminals 4 and 5 or 9 and 10). : Dual display showing Measured Value ( PV
Use to select your sensor code (e.g., K for K-type, Pt for PT100). Press SET to confirm. 3. Changing Temperature Units ( C-F ) In the main menu, locate the C-F parameter. Press SET to modify. Select C for Celsius or F for Fahrenheit. Press SET to save. Tuning and Operation Running the Auto-Tune Feature
: Connect 100–240V AC power to terminals 1 (Line) and 2 (Neutral) . Temperature Sensor (Input) :
: Illuminates when the control output is actively heating. AT Light : Flashes during the automatic tuning cycle. ALM Light : Illuminates when an alarm threshold is crossed.
ALM1 / ALM2 : Signals that user-defined high or low boundary alarm states have been tripped.
Choose your sensor type (e.g., K for a K-type thermocouple). Press to confirm. 3. Setting the Target Temperature
