MN-S4HT-500 Schneider MicroNet Temp Humidity Sensor Fan Speed Controller
The Schneider Electric MN-S4HT-500 is the most fully-featured sensor in the MicroNet MN-S series, integrating temperature sensing, humidity sensing, setpoint adjustment, override control, full Controller Mode Functions, On/Off/Auto switching, and fan speed selection into a single compact wall-mounted unit. The thermoset polymer capacitive humidity element provides excellent long-term accuracy stability. All data is transmitted to the MicroNet VAV controller via S-Link bus — a two-wire power-and-data combined connection.
Designed for premium commercial environments where occupants require maximum local environmental control and humidity monitoring is operationally critical.

Applications
The MN-S4HT-500 is specified for luxury hotels, hospital patient rooms, research laboratories, and executive suites where occupant comfort, indoor air quality monitoring, and HVAC mode autonomy are all required simultaneously. The combined humidity + temperature display at the zone level reduces the need for separate handheld measurement instruments during facilities inspections.
