D-F228 + Temperature Controller

D-F228+ differential-temperature controller is mainly used in forced solar circulation, Hot water circulation, return water system control, etc.,Can detect the temperature difference between a [high-temperature point] (e.g., collector) and a [low-temperature point] (e.g., water tank),When the [temperature difference] reaches the user's preset value,Automatically activates the relay output to control loads such as the [circulation pump], circulating hot and cold media between high- and low-temperature points,Thereby reducing the temperature difference between the high- and low-temperature zones (referred to as the temperature differential).

Compact size and fast track mounting design.

• Measures the temperature difference between two points and activates one relay output when the set positive differential is reached

• Relay output normally open, normally closed point

• Press F1 to independently view the high- and low-temperature readings

• High-temperature, low-temperature measured temperature values can be manually corrected

• Setting parameters Power-off memory function

• High-precision NTC 10K temperature sensor for stable, reliable measurement

• Long-distance temperature measurement (100 m) requires no compensation

• Standard rail mounting, tiny size, easy installation

• Switching power supply for stable operation at AC80～240V
