Temperature and Humidity Regulator
Humidistat is designed for two-state control e.g. heating, ventilation, humidifier, dehumidifier, etc. The transmitter is equipped with two relay outputs for alarm indication or control of external devices. Each relay can be assigned to any measured or computed value. For each relay setting of delay, hysteresis, an audible alarm is enabled. Measured temperature and relative humidity are recalculated to other humidity interpretations - dew point temperature, absolute humidity, specific humidity, mixing ratio, or specific enthalpy. Parameters are easily adjustable from the regulator keyboard or the computer. A large dual-line LCD for simultaneous display of temperature, relative humidity, or other calculated humidity interpretation is an advantage. State-of-the-art capacitive polymer sensor ensures excellent calibration long-term stability, inertia against water, and condensation. The transmitter is designed for use in a non-aggressive environment.
Humidistat Applications
- Building management and automation
- Server rooms

- Manufacturers
- Museums, archives, galleries
- Air-conditioned rooms, HVAC
- Weather stations
Regulator mounting and connection
Regulators are designed for wall mounting. The device must be mounted on the plane's surface to prevent its deformation. Mounting holes and connection terminals are accessible after demounting four screws in the corners of the box and removing the lid. There is recommended to use screws with a half-round head with cross-recessed screw ST 3.9 (DIN 7981). Lace the lead-in cable with an outer diameter of 3 to 6.5 mm through the glands at the case wall and connect them according to the schematic below. Terminals are self-clamping and can be opened by a suitable screwdriver. For the opening, insert the screwdriver into a smaller terminal hole and lever by him. Do not forget to tighten the glands and case lid with inserted packing after the cables connect. Insert the attached plug into unused cable glands too. Do NOT connect the regulator under voltage.
Measured values are also converted to other humidity interpretation
- Dew point temperature
- Absolute humidity
- Specific humidity
- Mixing ratio
- Specific enthalpy
