Eberle UTE 3500 Room Thermostat Smart Home Capable Instruction Manual

Eberle UTE 3500 Room Thermostat Smart Home Capable

Installation and Operating Instructions

Important!
The device may only be opened by an electrically skilled person and must be installed as shown on the circuit diagram on the device and in these instructions. The existing safety regulations must be followed.The relevant installation measures must be taken to achieve the requirements ofprotection class II. This independently mountable electronic device is used to control the temperaturein dry and enclosed rooms only, with normal environment. This device conforms to EN 60730, it operates according to type 1Y (UTE 3500) and 1B (UTE 3800-U).

Area of use

The electronic temperature controllers UTE3500 and UTE 3800-U can be used to control the floor and room temperature. They are suitable for water-based and electric heating systems.

Installation site

• The controller should be mounted in a place in the room that is easy to access for operation.
• Mounting height: approx. 1.5 m above the floor.
• Preference should be given to installation on an internal wall. Avoid external walls and draughts from windows and doors.
• Ensure that the room’s normal convection air reaches the controller freely without restriction. The controller should therefore not be mounted inside shelf units or behind curtains and similar coverings.
• Extraneous heat has a negative influence on the control accuracy.
• Direct sunshine, and proximity to televisions, radios and heaters, lamps, stoves, and heating pipes must be avoided.
• Install in flush-mounting box 60mm

Electrical connection

Important!
Disconnect the electric circuit from the mains Connection in the following steps:

1. Connect the power module according to the circuit diagram (see bottom of housing or circuit diagram in these instructions.)
2. Note the mounting direction of the power module in the box (arrow pointing upwards)
3. Mount the cover frame
4. Fixate the cover frame with the decorative frame holder
5. Insert the logic module

Attention!
Only mount in non-conducting (plastic) flash-mounting boxes only.

Attention! Risk of fatal injury, due to electric shock. The appliance is not a safety extra-low voltage device (SELV). The sensor cables are connected to 230 V AC mains voltage. Only use sensors with insulated cables. Failure to do so may result in serious injury or death.

UTE 3800-U

Attention!
Risk of fatal injury, due to electric shock. The appliance is not a safety extra-low voltage device (SELV). The sensor cables are connected to 230 V AC mains voltage. Only use sensors with insulated cables. Failure to do so may result in serious injury or death.

Status-LED

Note: The heating and cooling LED shows the difference to the setpoint, not the switching status of the output.

Use case (depending on variant)

Selection after the first start or inside the menu:

• P2: Hydronic Underfloor Heating – Room
• P3: Hydronic Radiator – Room
• P4: Blow convector – Room (Attention: Use UTE 3500 only with external relay)
• P5: Electrical Radiator, Infrared – Room (Attention: Use UTE 3500 only with external relay) P6: Hydronic Underfloor Heating – Limiter
• P7: Electrical Underfloor heating – Floor

Confirm the selection with [O]­Button. P8: Electrical Underfloor Heating – Limiter

Actuators NC / NO (only UTE 3500)

Via the installer menu, it can be adjusted whether the thermostat controls the actuators normally closed (NC; default) or normally open (NO).

Universal input: setback input/presence sensor The function of the universal input can be adjusted in the Installer Menu (default: setback input). When the setback input is energized, the controller switches to unoccupied mode. When the presence sensor input is energized, the controller switches to occupied mode.

Heating / Cooling input

H/C­terminal connected to voltage means cooling mode, and not connected means heating mode. In case of cable used longer than 100m an anti­in­terference capacitor (Capacitor 230 VAC 0,33µF or comparable) between control line H/C and neutral line N can be installed at any position to avoid a malfunction.

Matter WiFi Configuration

How-to Video:

Via Matter the thermostat can be connected to smart home apps and the respective controllers/hubs from Apple, Google, Amazon and Samsung. To integrate the thermostat into a Smart Home App and the respective Matter WiFi network, scan the QR code on the back of the logic module with a smartphone or type in the eleven-digit Matter provisioning code. Press the [O] button for 5 seconds until the thermostat displays „Jn“ for Join Mode. The WiFi LED lights up yellow.

If an error occurs during connection, the controller displays „Er“ for Error: The WiFi LED lights up red.

Acknowledge with [O] and restart the Matter WiFi configuration.
