Controller TM Models Available The Tempatron MINITHERM6-MCU quad range temperature controllers MINITHERM6-MCU are designed for a wide range of OEM heating and refrigeration Quad Range Temperature Controller applications, and are ideal for replacement of electromechanical controls. Product Features Any one of four commonly used temperature ranges can be selected by Ideal for OEM heating and refrigeration 4 temperature range options cutting just two wire links. They are available in 110Vac and 30Vac For use with 10K NTC thermistor probe versions (or 4Vdc to special order) with a 16 Amp changeover relay 16 Amp changeover relay output 110Vac, 30Vac or 4Vdc powered output and are compatible with industry standard 10K ( 5C) NTC Energy regulation feature thermistors. Lockpot operation feature Onboard LED or optional remote LED These chassis mounting modules measure only 70mm x 45mm and have an integral energy regulation feature (link selectable) which reduces the connected heating/cooling power to 33% duty cycle as the temperature approaches the setpoint. An onboard (or optional remote) LED indicates current temperature status and diagnostic conditions. For temperature control in machinery, systems and operational processes i Dimensions Connections 45.0 Note: The thermistor connections are not isolated from the AC supply. Probe LED The unit is set for 33% M3 onboard LED indication PAD To select remote LED T3 T Links T2, T2R, T3, T3R indication, spin cut the Leave in place for copper pad adjacent to K temperature range of 73 to 99C the LED to disconnect the T3R T R Cut links T and T R for onboard LED. Connect temperature range of to 54C the remote LED to the LED Cut links T3 and T3R for -pin LED Molex header temperature range of - 0 to +6C .0 (ensuring LED cathode is Cut links T , T3 and T3R for connected to pin K). 17.0 temperature range of 4 to 34C. N/O C N/C N L Load Connection Power Supply 33% Duty Cycle This feature cycles the output on for 6.4 seconds every 19. seconds as the temperature approaches the setpoint. This can reduce over/undershoot in many basic temperature control applications. It is primarily intended for heating applications. Spin cut the pcb pad (copper side, top right) adjacent to the 8-pin integrated circuit to enable this feature.

Flashing on/off: On, temperature in range To use this feature simply:- 1. Set up the required temperature using the adjustment potentiometer. On, blinking off: . Switch off the auxiliary power to the controller. On, nearing set temperature 3. Insert the red programming link into the pin header marked LP. Continuous on: 4. Switch on the auxiliary power to the controller. The LED will blink on for 5 seconds Off, at set temperature indicating LOCKPOT off, then change to continuous flashing indicating LOCKPOT on. 5. Switch off the auxiliary power to the controller and remove the programming link. Flashing seconds: 6. Repeat above to re-select LOCKPOT off. Off, lockout failure Electrical Connections: Five 6.3mm blades for power (L, N) & relay output (N/C, C, N/O) -pin molex connector for thermistor -pin molex connector for remote LED Mounting: Two M3 fixing pillars spaced 33mm Operating Temperature: - 0C to 65C Enclosure Code: Case IP00 Weight: 35g Specification subject to change without notice.
