Selecting the Installation Site
To ensure reliable room temperature measurement, the internal temperature sensor must be protected from external influences and temperature fluctuations.
Insert Installation Site
- Recommended installation height: 1 meter above the floor.
- Avoid installation near windows, doors, or ventilation openings.
- Do not install above heaters or other heat sources.
- Do not cover or install behind curtains.
- Avoid direct sunlight and lamp light.
Floor Sensor Installation Site
For reliable operation, protect the floor sensor from moisture, mechanical stress, and temperature fluctuations.
- Install the sensor in the middle of the underfloor heating unit's loops.
- Lay the sensor cable in a plastic tube with an inner diameter of at least 16 mm.
- Attach tape to the end of the tube and cut a slice to allow condensation water to drain.
- Ensure tube corners are not too tight, as they can affect sensor cable installation.
Electrical Connections
DANGER: HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Safe electrical installation must be performed only by qualified professionals with knowledge in connecting to installation networks, multiple electrical devices, laying electric cables, and relevant safety standards and regulations. Failure to follow these instructions can result in death or serious injury.
DANGER: RISK OF FATAL INJURY FROM ELECTRIC SHOCK
The output may carry electrical current even when the load is switched off. Always disconnect the device from the power supply via the fuse in the incoming circuit before working on the unit. Failure to follow these instructions can result in death or serious injury.
DANGER: RISK OF FATAL INJURY FROM ELECTRIC SHOCK
The device is not a Safety Extra Low Voltage (SELV) device. Sensor lines are connected to the mains (AC 230 V) line. Use only sensors with mains voltage basic insulated cable. Failure to follow these instructions can result in death or serious injury.
NOTE: It is recommended to use only sensors tested as compatible. Refer to the Device User Guide for a list of compatible sensors.
A: Load connection: max. 16 A.
B: Input for floor sensor (optional).
Mounting
Optional IP31 Protection:
- 1. Place the gasket on the fixing plate.
- 2. Complete the device with an ELKO RS16 or ELKO Plus frame.
Module Installation:
- 1. If not preconfigured, pull the frame over the module, minding the orientation of the module springs.
- 2. Clip the module into the insert.
NOTICE: EQUIPMENT DAMAGE
The module is firmly connected to the insert with a cable. Do not pull hard on the module or insert. When unmounting, note the cable length. Failure to follow these instructions can result in equipment damage.
Presets
A preset must be selected after the first power-up or reset.
Preset | Configuration |
---|---|
P1 | Heat Pump/Oil Boiler (Room sensor) |
P2 | Hydronic Radiator/Gas Boiler (Room sensor) |
P3 | Hydronic Underfloor (Room sensor) |
P4 | Electrical Radiator (Room sensor) |
P5 | Electrical Underfloor (Room sensor - without floor limit sensor) |
P6 | Electrical Underfloor (Room sensor - with floor limit sensor) |
P7 | Hydronic Underfloor (Floor sensor) |
P8 | Electrical Underfloor (Floor sensor) |
P9 | Regulator Mode (based on percentage) |
Selecting a Preset
To switch between presets, press the '+' or '-' push-button. Use '+' to increase the preset value and '-' to decrease it.
Confirming the Preset
To confirm the selection, press and hold both the '+' and '-' buttons simultaneously for more than 1 second.
Detailed information about presets can be found in the Device User Guide.
