The MFR 012 is a mechanical hygrostat used to prevent condensate by regulating heating and fans based on relative humidity levels, with an adjustable setpoint range of 35% to 95% rF and a switching differential of 4% rF. It features a snap-action changeover contact with a switching capacity of 5 A AC at 250 VAC and 0.6 A DC at 30 VDC, and operates reliably over more than 50,000 cycles. The device is housed in a light grey plastic casing rated UL94 V-0 with IP20 protection and mounts via a clip for 35 mm DIN rail. It measures 2.6 in height, 2 in width, and 1.5 in depth, and connects to rigid wire up to 2.5 mm² or stranded wire up to 1.5 mm² with ferrules. The operating temperature range is 32 °F to 140 °F, and it meets CCC and CQC standards.
The hygrostat is used to prevent condensate and regulates heating and fans. From a critical relative air humidity of 65 %, the temperature is increased so that the dew point is raised.
