Product

This controller is used to manage heating and cooling equipment, filter
fans, or signal devices. During operation, the LED indicator will illuminate
(e.g, heater on).

•  Adjustable and pre-set relative humidity
•  Optional LED operational indicator
•  High switching performance
•  35mm DIN rail mounting
•  Built-in temperature compensation
•  Long service life

This electronic humidity controller monitors the relative humidity inside an
electrical enclosure. It activates a heater once the humidity reaches the set
point to prevent condensation. An LED indicator on the adjustment knob
illuminates when the heater is operating.

•  Adjustable and pre-set relative humidity
•  Optional LED operational indicator
•  High switching performance
•  Easy installation on 35mm DIN rail
•  Built-in temperature compensation
•  Long service life

The MFR012-2 humidistat is designed to control a heater within a switch
box. When humidity exceeds the set level, the heater activates to expel
moist air. This method effectively prevents condensation and rust.

•  Adjustable Humidity Control
•  Changeover contact (SPDT)
•  High switching capacity
•  Easy access for setup and wiring
•  DIN rail mounting clamp
•  Long electrical service life

Operation & Control:
The operating range of the humidifier is set via the range knob. The humidity sensor
continuously monitors the environment. When the actual humidity falls below the set
value, output power is supplied to the load. When the actual humidity rises above the
set value, the output power is cut off.

To prevent the load from frequently cycling on and off at the set point, this product
incorporates a hysteresis of 5%- 10%. This means the device will only reactivate after
the humidity has dropped 5-10% below the set point.
Load Selection:The product can be configured to drive loads of different sizes and
types based on customer requirements.

•  35% - 95% adjustable relative humidity range . Long service life
•  Easy installation on a 35mm DIN rail
•  High switching performance
•  Single-pole, double-throw (SPDT] contact

This temperature regulator is ideal for controlling filter fans, heaters, and heat
exchangers. It can also serve as a signal generator for monitoring the internal
temperature of control cabinets.

•  Compact size
•  Convenient wiring via terminal blocks
•  Dynamic heating with high-temperature limitation
•  Long service life
•  Easy installation on 35mm DIN rail
•  Wide operating voltage range

Performance & Specifications
Sensing Element: Thermistor
Contact: Single-pole changeover, quick-break
Wiring: Front-access terminal blocks
Mounting: Vertical/horizontal 35mm DIN rail mount (EN 60715); optional clip
adapter for TS/35 cabinet rails

Panel Thermo-Hygrostat

•  Compact size
•  Electronic control system
•  LED status indicator for contact operation
•  Mounts on standard 35 mm DIN rail (EN 60715)

Control Heater:
When the internal cabinet temperature falls below the minimum set
value, the circuit closes to begin heating. The circuit opens when the
temperature exceeds the set value.
Control Fan Filter:
When the internal cabinet temperature rises above the maximum set
value, the circuit closes to activate cooling. The circuit opens when the
temperature drops below the set value.

•  Compact size
•  Long electrical service life
•  Easy installation on 35mm DIN rail . Wide temperature setting range
•  Snap-action metal temperature sensing contact
•  Convenient wiring and simple setup

Technical Specifications
Alarm Output Contact: Passive contact, rated for AC 250V 5A
Alarm Logic (NC - Normally Closed): Contact closes upon dehumidification
function failure

Dehumidification function failure is defined as:
Temperature or humidity sensor malfunction, OR
The relative humidity remains 280% after the dehumidifier has operated
continuously for 24 hours

• Four selectable operating modes with configurable ambient temperature and
  humidity thresholds
• Utilizes a capacitive humidity sensor for low power consumption and stable
  performance
• Passive relay output for driving cooling fans, TEC, heating wires, and other devices
• LED indicator displays the operational status of the relay
• Wie-range AC power supply: 85~240V
• Ultra-compact design with only 18mm width for easy 35mm DIN rail installation
• Designed for temperature and humidity control in power distribution cabinets

A Temperature Controller with Dual Temperature Settings

Normally Open (NO) Contact: Typically used to monitor filter fans or heat
exchangers, and closes the circuit when the temperature exceeds the set
value
Normally Closed (NC) Contact: Typically used to connect heaters and opens the
circuit when the temperature reaches the set value.
This design allows independent switching of heating and cooling equipment,
preventing temperature deviations common with traditional switching
methods.

•  Wide temperature setting range
•  Integrated NO and NC contacts
•  Bimetallic temperature sensing element
•  Easy installation on 35mm DIN rail
•  High switching performance
•  Independent temperature settings

KTO 011:
Thermostat (Normally Closed): Typially used to connect heaters and
open the circuit when the temperature reaches the set value.
KTS 011:
Thermostat (Normally Open): Typically used to monitor filter fans or
heat exchangers, and close the circuit when the temperature exceeds
the set value.

• Compact size
• Long electrical service life
• Easy installation on 35mm DIN rail
• High switching performance
• Easy wiring and simple setup

JTO 011:
Thermostat (Normally Closed): Commonly used to connect heaters and
disconnect the circuit when the temperature reaches the set value.
JTS 011:
Thermostat (Normally Open): Commonly used to monitor filter fans,
heat exchangers, or close circuit output signals when the temperature
exceeds the set value.

• Compact size
• Long electrical service life
• Easy installation on 35mm DIN rail
• High switching performance
• Easy wiring and simple setup
