The Andivi TRC-A/D room controller is a multipurpose programmable room thermostat used to control temperature and fan speed.
It is intended for managing convectors and for regulating underfloor heating, ceiling cooling systems, radiator systems and other cooling/heating elements.
The difference between a classic thermostat and a room controller thermostat, like Andivi TRC, is in its energy saving ability.
Classic thermostats do not optimize for regulation, they only turn valves on and off. Often classic thermostats overheat and overcool rooms, hence using more energy while providing a lower level of comfort.
Room controller thermostats optimize their performance by working with PI regulator functionalities. The consequence is better living conditions while saving energy over time.
Prefer a sleek, simple solution? The TRB Programmable Touch Thermostat offers a sophisticated design with intuitive functionality.

Humidity module
Calm Air Flow
Comfort Fan Coil regulation (PI regulation) with minimum air flow allows a pleasant heating/cooling change.
Detect Guest Presence
Detect guest presence in the room by directly connecting the Energy Saving Switch to the room controller: save energy while the guest is not in the room.
Humidity module
Andivi TRC-Ah/Dh room controllers have the same features as the Andivi TRC-A/D room controllers, but are upgraded with a humidity module that allows for humidity monitoring and contol.
Multi-purpose
Multi-purpose thermostat for manual/automatic control of fan coils, underfloor heating systems, ceiling cooling systems, radiator system and other cooling/heating elements.
Reception Overview
Monitor in-room guest presence status and control temperature in all the rooms straight from the reception. The Andivi TRC room thermostats have the ability to be connected to a central building automation system, to a guest room management system within a hotel or any other automation platform.
The Andivi TRC room thermostats have the ability to connect every guest room in the hotel from a single platform like VIA ,or other 3rd party systems.
Use Cases
The Andivi TRC room regulator – room controller can be connected in several scenarios: 2-Pipe fan coil, 4-Pipe fan coil, floor heating, radiator heating, ceiling cooling, ventilation system, VAV system, VRV systems, air zone heating & cooling with classic remote access and remote access through Modbus.
The use cases support various schemes ready for connecting the room regulator in hotels, offices, condominiums and homes & can be downloaded here.
