PI (proportional plus integral) control action provides accurate, stable and comfortable temperature control. Compatible with series 70 direct-coupled damper / valve actuator like ML7161,ML7174, ML7420 / ML7421series ML7425,ML7984 series, N20010, S10010, M7410E series, CN7505, CN7510 / CN72 seriesCN7220 & CN7234 also VC79 series etc. Backlit LCD to display both setting and measured value. Adjustable Zero Energy Band, On/Off Differential, Proportional Band and Temperature Offset. Analog output can be forced manually to be convenient for installation & commissioning. Optional 2 to 10Vdc or 4 to 20mA direct acting and reverse acting analog output. Selectable internal and external temperature sensor. Wide temperature control range (-20 to 110°C by using external temperature sensor) is suitable for extreme temperature control such as steam and ice water. Watch Dog Timer: to resume the controller from hanging condition. Brownout effect to avoid malfunctioning and care on power ON and power OFF. Pluggable terminal block allows pre-wiring outside of the controller. Compact size and slim design provide elegant and attractive modern style appearance.

HONEYWELL COMMERCIAL THERMOSTATS HONEYWELL manufactures a wide range of 12.7mm (0.5 inch) commercial snap-action thermostats for possible use in a wide range of small and major appliances, office copy machines, medical equipment, heat detectors, HVAC equipments etc. Download Catalog Ask a question about this product DESCRIPTION DEFINITION OF TERMS• Automatic Reset: A type of thermostat that will automatically reset at a specific temperature (i.e. a thermostat operates at65,5 oC [150 oF] and resets at 48,89 oC [120 oF]).• Bimetal: Two dissimilar metals bonded together to form the material for manufacturing thermally-sensitive discs which actuatethe thermostat.• Close on Rise (COR): Refers to operation of the contacts. When the temperature rises to its set point, the contacts close ormake contact and complete the circuit.• Contact Resistance: The value of resistance measured between the terminals.• Dielectric Strength: The value of insulation between two electrically conducting parts. It may be tested by the application of apredetermined overvoltage for a specified time.• Differential: The temperature difference between the operate and reset set points, also known as operate and reset.- Nominal: The temperature difference between nominal set points regardless of tolerance.- Maximum: Maximum number of degrees between actual opening and closing set points.- Minimum: Minimum number of degrees between actual opening and closing set points.• Exposure Temperature: Thermal environment of a device during application operation.• FLA (Full Load Amps): Current taken from the line by the motor when the motor is yielding the rated hp at the rated voltageand frequency.• Life Cycles: The endurance rating of the thermostat expressed in number of operations with stated electrical load applied.Temperature limit application = open on rise.• LRA (Locked Rotor Amps): The amount of current the motor can be expected to draw under starting conditions when fullvoltage is applied, also known as starting inrush current.• Manual Reset: A bimetal thermostat with a reset button that must be pressed to reset the contacts.• Open on Rise (OOR): Refers to the operation of contacts. When the temperature rises to its set point the contacts open,terminating the circuit.• Overmold: Encapsulation with an insulating material.• Phenolic: Thermoset plastic used for the insulating body of the thermostat.• Set Point: The nominal temperature at which the thermostat operates.• SPST (Single Pole/Single Throw): A switch with one current path which can be either open or closed.• Tolerance: The allowable range above and below the set point temperature.• Operate: Change of state when the thermostat reaches its set point.• Reset: Change of state when the thermostat returns to its original condition prior to operation.NOTES• Standard Temperature Characteristics Tables:- Temperatures: Please consult applications engineering for temperature ranges, tolerances and differentials not noted.The operating temperature ranges include tolerances.- Tolerances: The ± tolerances given have been established after review of many thermostat applications. Attempts shouldbe made to establish the widest acceptable tolerance possible.• UL and CSA Approvals: 12,7 mm [0.5 in] thermostats are available with multiple agency approval for incorporation intoequipment.• Fan control applications: Require thermostat set points to be derated by 20 °C from the equivalent temperature limitapplication. They also close on rise.• Dimensions: Are for reference only and are given in mm [in].
