Caution! Ensure that the installation complies with local safety  

regulations.  

Warning! Before installation or maintenance, the power supply must first  

be disconnected in order to prevent potentially lethal electric shocks! In-  

stallation or maintenance of this unit should only be carried out by quali-  

fied personnel. The manufacturer is not responsible for any eventual  

damage or injury caused by inadequate skills during installation, or through  

removal of or deactivation of any security devices.

The room thermostat regulates the heating and/or cooling in a room via  

on/off outputs for 2- or 4 pipe installations, and has a function for three-  

speed fan control. The large LCD touch screen displays status and is also  

used to access all parameters, such as setpoint, hysteresis, fan speed etc.  

Dimensions, external (WxHxD)  

95 x 95 x 50.5 mm  

The unit has a built-in temperature sensor for controlling the room  

temperature. The change-over function can be controlled using an  

external PT1000 sensor or via a digital input connected to any potential  

free contact. Functions such as mould protection and automatic valve  

exercise ensures a proper functionality and a problem free installation  

over time.  

Installation  

1. Separate the back plate from the display part with a small screw  

driver. Insert the screw driver in the grooves at the bottom of the  

unit.

REGIN RCFD-230C Fan Coil Room Thermostat Instructions Overview

Summary of Contents

• Page 1: Caution! Read and understand the instruction before using the product. Warning! Before installation or maintenance, the power supply must first be disconnected to prevent potentially lethal electric shocks. The room thermostat regulates the heating and/or cooling in a room via on/off outputs for 2- or 4-pipe installations. The unit has a built-in temperature sensor for controlling the room temperature. The large LCD touch screen displays status and is also used to access all parameters, such as setpoint, hysteresis, fan speed, etc. Functions such as mould protection and automatic valve exercise ensure proper functionality and a problem-free installation over time. Supply voltage is 230 V ~ (207…253 V ~ 50/60 Hz). Power consumption is less than 2 VA. Ambient humidity ranges from 10 to 90 %RH (non-condensing). Dimensions, external (WxHxD) are 95 x 95 x 50.5 mm.
• Page 2: The thermostat can be in three different modes: idle, active, and setpoint mode. In idle mode, the thermostat has been inactive for a set time, dimming all buttons except the arrows. The active mode shows either the calculated setpoint or the current room temperature. Setpoint mode is activated by pressing one of the arrows in active mode. The thermostat settings can be controlled via display buttons, a parameter list, or Modbus variables. The parameter list is accessed by pressing the arrow buttons simultaneously for five seconds. The thermostat regulates heating and cooling for 2- or 4-pipe systems. Warning: Power supply must be disconnected before installation or maintenance to avoid electric shock. Installation and maintenance should only be performed by qualified personnel. The display behaves differently depending on the mode and state of the thermostat.
• Page 3: Interne serielle Schnittstelle, Stopp- Tasten sichtbar im Display Kabelanschluss: Schraubklemmen, max. 1,5 mm2 Abmessungen, außen (B x H x T): 95 x 95 x 50.5 mm Installation: Trennen Sie die Rückseite vom Teil mit Display. Der Thermostat kann sich in einem der folgenden Stati befinden: AUS, Standby, Belegt. Der Thermostat kann sich in 3 verschiedenen Modi befinden: Inaktiver Modus, Aktiver Modus, Sollwert-Modus. Einstellungen am Thermostat: Bedienelemente, Parameterliste, Modbusvariablen. Durch gleichzeitiges Drücken der Pfeiltasten AUFWÄRTS/ABWÄRTS erreichen Sie die Parameterliste. Dieses Produkt trägt das CE-Zeichen.
• Page 4: Élément sensible, température Précision, température Le thermostat d'ambiance régule le chauffage et/ou le rafraîchissement d'une pièce via ses sorties ToR pour des installations à 2 ou 4 tubes. Le large écran LCD tactile affiche l'état de l'installation et peut également être utilisé pour accéder aux paramétrages tels que la consigne, l'hystérésis, la vitesse de ventilateur, etc. Attention ! Veuillez lire attentivement l'instruction avant d'utiliser le produit. Avertissement ! Avant de procéder à l'installation ou à la maintenance de l'appareil, il convient de couper l'alimentation afin d'éviter tout risque de choc électrique. Les opérations d'installation et de maintenance doivent être effectuées par un professionnel qualifié. L'unité d'ambiance est équipée d’une sonde de température. Les fonctions telles que l'anti-moisissure et l'exercice des vannes automatique permettent de garantir le bon fonctionnement de l'installation dans la durée. Les paramètres du thermostat peuvent être contrôlés comme suit : RCFD-230C.
• Page 5: A l'écran : paramètres d'utilisateur tels que l'ajustement de consigne et la vitesse de ventilation. Ce produit porte le marquage CE. Liste des paramètres : Configurations rapides pour l'installateur. Variables Modbus : contrôle avancé du thermostat via la communication Modbus. On accède à la liste des paramètres en appuyant simultanément sur les boutons Flèche vers le haut et Flèche vers le bas pendant 5 secondes. Tous les paramètres et variables sont répertoriés dans le manuel. L'écran réagit différemment selon le mode et l'état du thermostat. Les états du thermostat sont : Arrêt, Éco (Standby), Confort (Occupied). Le thermostat peut être dans 3 différents modes : inactif, actif, consigne. Le thermostat entre dans le mode consigne lorsqu'une des flèches est activée pendant le mode actif.
