Setback Input / Presence Input

The function of the universal input can be defined in the installer settings (default: setback input). If the setback input is energized (230 VAC), the thermostat switches to unoccupied mode. If the presence input is energized (230 VAC), it means that the thermostat switches to occupied mode.

Presets

Depending on the variant, the default preset values are:

• Heating: 21°C
• Cooling: 19°C

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 of protection class II.
• This independently mountable electronic device is used to control the temperature in 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 UTE 3500 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 Environment

• The thermostat 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 thermostat freely without restriction. The thermostat 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, 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:

• Connect the Powermodule according to the circuit diagram (see bottom of housing or circuit diagram in these instructions.) Note the mounting direction of the power module in the box (arrow pointing upwards)
• Mount the cover frame with the decorative frame holder on the power module
• Mount the logic module to the Decorative Frame Holder

Important!
Mount in non-conductive (plastic) flush-mounting boxes only.

Caution!
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.

Presets (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
• P5: Electrical Radiator, Infrared – Room
• P6: Hydronic Underfloor Heating – Limiter
• P7: Electrical Underfloor Heating – Floor
• P8: Electrical Underfloor Heating – Limiter

Technical data

Actuator NC / NO
Via the installer menu it can be adjusted whether the thermostat controls the actuators normally closed (NC) or normally open (NO). The preset is normally closed (NC).

Setback Input / Presence Input
The function of the universal input can be defined in the installer settings (default: setback input). If the setback input is energized (230 VAC) the thermostat switches to unoccupied mode. If the Presence input is energized (230 VAC), it means that the thermostat switches to occupied mode.

Heating / Cooling input
H/C-terminal connected to voltage means cooling mode, not connected means heating mode. In case of cable used longer than 100m an anti-interference capacitor (Merten 542895 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.
