Managing the climate in a greenhouse or livestock facility means controlling multiple parameters simultaneously, across different zones, with different devices. When each function requires a separate controller, the installation becomes harder to wire, program, and maintain over time.<\/p>\n

X-3TRH<\/strong><\/a> solves this with a single device: a digital controller with 3 independent smart contacts, each individually configurable as a thermostat, a humidistat, or both. One device. Infinite configurations.<\/p>\n

What is X-3TRH<\/h2>\n

\"\"X-3TRH<\/strong> is a digital controller developed by Agricontrol for climate management in greenhouses and livestock facilities. It integrates three independent relays, each individually programmable to manage temperature, relative humidity, or both variables in combination. Each contact manages two intervention thresholds (low and high) with adjustable differential.<\/p>\n

The third contact (S3) features a NO\/NC changeover relay (Normally Open \/ Normally Closed), making it directly compatible with any external device \u2014 alarm systems, third-party equipment \u2014 without additional adapters.<\/p>\n

The problems it solves in the field<\/h2>\n

In real production environments (commercial greenhouses, horticultural facilities, poultry farms ecc) climate control requires simultaneous management of multiple variables. Typical configurations include:<\/p>\n

    \n
  • Heating + air circulation + alarm for high and low temperature<\/li>\n
  • Ventilation + cooling activated by temperature and\/or humidity<\/li>\n
  • Heating + cooling managed by temperature and\/or humidity<\/li>\n<\/ul>\n

     <\/p>\n

    With a traditional single-function controller, each of these scenarios would require multiple devices, additional wiring, and more potential failure points. X-3TRH<\/strong> handles all of them within a single unit, reducing installation complexity and maintenance costs.<\/p>\n

    Key technical features<\/h2>\n
      \n
    • 3 independent smart contacts, each individually configurable as thermostat or humidistat<\/li>\n
    • Combined temperature + humidity probe (SHT85 sensor, included in protective shelter)<\/li>\n
    • Probe installable up to 100 metres from the control unit: suitable for large-span structures<\/li>\n
    • S3 contact with NO\/NC changeover relay for full compatibility with any device<\/li>\n
    • Physical buttons, gloves-ready: operable by any worker, with or without protective gear<\/li>\n
    • IP55 protection: resistant to dust and water jets, even in harsh environments<\/li>\n
    • Accuracy: +\/-0.5 degC \/ +\/-2% RH<\/li>\n
    • Supply: 230 Vac, 50\/60 Hz. Outputs: 3 x 2A @ 250 Vac<\/li>\n
    • CE certified. Made in Italy. 1-year warranty<\/li>\n<\/ul>\n

       <\/p>\n

      Why choose a multi-contact controller<\/h2>\n

      Single-function controllers\u00a0 (one thermostat, one humidistat) handle one variable at a time. For installations requiring multiple control zones or parameters, the result is a control panel crowded with separate devices, each with its own programming and maintenance requirements.<\/p>\n

      X-3TRH consolidates these functions into a single unit: three independent relays, one combined probe, one programming interface. Simplicity here is not a compromise on performance, it is the design intent.<\/p>\n

      Designed for people who work in the field<\/h2>\n

      X-3TRH<\/strong> requires no IT expertise to programme. The configuration language was designed to be accessible to any operator, regardless of technical background. Physical buttons work with work gloves on. IP55 protection ensures reliable performance in humid, dusty, or frequently washed environments.<\/p>\n

      The combined probe, housed in a white protective shelter, can be positioned up to 100 metres from the control unit \u2014 a key feature for large-span greenhouses or poultry houses where the measurement point does not coincide with the panel installation point.<\/p>\n

      45 years of experience in agricultural climate control<\/h2>\n

      X-3TRH<\/strong> is developed by Agricontrol by Termotecnica Pericoli<\/strong>, a brand with 45 years of history in climate control for greenhouses and agricultural structures, based in Albenga (SV), Italy. The integration into the Termotecnica Pericoli industrial ecosystem has expanded Agricontrol’s manufacturing capabilities and international commercial reach, while preserving the technical identity the brand is known for: no planned obsolescence, genuine customisation to each installation’s requirements, and direct post-sales technical support to end users.<\/p>\n

      Technical specifications<\/h2>\n
        \n
      • Supply: 230 Vac, 50\/60 Hz<\/li>\n
      • Outputs: 3 x 2A @ 250 Vac<\/li>\n
      • Temperature sensor accuracy: +\/-0.5 degC @ 25 degC (included)<\/li>\n
      • Humidity sensor accuracy: +\/-2% RH @ 25 degC (included in shelter)<\/li>\n
