HOW TO USE THE REGULATOR

PRINCIPLE OF OPERATION

The main function of the EU-RI-1 room regulator is to maintain the pre-set room/floor temperature by sending a signal to the EU-I-2, EU-I-2 Plus, EU-I-3 or EU-I-3Plus controller, when the room or floor temperature is lower than the pre-set value.

 OPERATION MODES

The regulator may operate in one of the two operation modes available:

•   Day/night mode – in this mode the pre-set temperature changes depending on the time of the day. The user presets the temperature values for both day-time and night-time as well as the time of entering day mode and night mode. In order to activate this mode, press MENU and hold until a corresponding icon (day /night mode) appears on the main screen.
•   Manual mode – In this mode, the user sets the temperature in the main screen view using PLUS and MINUS buttons. The manual mode will be activated automatically after pressing one of these buttons. Once this mode is activated, the previously selected mode enters ‘sleep mode’ and remains inactive until the next pre-programmed temperature change. Manual mode may be deactivated by holding the EXIT button for about 3 seconds.
•   Constant mode – Constant mode allows the user to set the desired temperature permanently. Activating this mode deactivates the day / night mode.
