Safety warnings

• Hot surface: Some parts of this product can become very hot and cause burns. Special care must be taken if children or vulnerable adults are present.
• Installation: The lowest heated rail must be at least 600 mm above the floor. Do not install the device in a draught or directly under a fixed power socket.
• Electrical: Connection must be performed by an authorized person. Connection to the earth is prohibited for the pilot wire (black wire).
• Water circuit: The service pressure must not exceed 4 bars. The boiler return tap must remain open in all cases to allow fluid expansion.

Installation

The device is designed for residential use. It is class 2 and IP24 protected. Ensure the device is installed according to local standards. Do not install shelves above the device. The bottom case must be at least 5 mm from the wall.

Electrical and hydraulic connection

Hydraulic: The mixed version has two 1/2 gas 15/21 F threaded ports at the base. Follow the flow direction indicated in the diagram. Use a new connection set.

Electrical: The device requires a 230V single-phase 50Hz power supply. Connect directly to the network after a circuit breaker without an intermediate switch. If using a load shedder, choose a pilot wire output load shedder to avoid damaging the thermostat.

Operation and modes

The control panel allows you to navigate menus, adjust temperature, and activate the Boost function. The device offers two main modes: Active Prog (follows internal/external programming) and Inactive Prog (follows the setpoint temperature at all times).

Boost Mode: Accelerates heating for a rapid temperature rise in the bathroom. The duration is adjustable (10 to 60 minutes).

Programming

You can program up to 3 Comfort temperature ranges for each day of the week. Outside these ranges, the device uses the Eco temperature. You can also copy programs from one day to another. For external programming via a pilot wire, the internal programming must be set to inactive.

Expert menu

To access advanced functions, press the Menu and Boost buttons simultaneously for over 3 seconds. This menu allows for temperature calibration, setting maximum temperature limits, adjusting Boost duration, and setting a PIN code for access control.

Troubleshooting

If the device does not heat up, ensure it is in Comfort mode and that the circuit breakers are on. If an error code appears: Err 3.3 indicates the control box is covered; Err 6 indicates the filter needs cleaning (if equipped with a fan) or air inlets are obstructed; Err 10 indicates a connection fault (contact your installer).

Maintenance

Dust the air inlets and outlets with a vacuum cleaner or brush about twice a year. Never use abrasive products or solvents. Have the inside of the device checked by a professional electrician every five years.
