4.4 Installing the VR 10 standard sensor

Note

You can use the VR 10 as a cylinder sensor (for

example, as an immersion sensor in a cylinder

dry pocket), as a flow temperature sensor (for

example, in the low loss header) or as a surface

mount sensor. We recommend that the pipe with

the sensor be insulated to ensure optimum tem-

perature recording.

▶ If you use the VR 10 as a surface mount sensor, secure

the VR 10 to a heating pipe using the enclosed strap.

5 Electrical installation

Danger!

Risk of death from live connections!

There is a risk of death from electric shock

when working on the open product and in the

electronics box of the boiler.

▶ Before working on the product and in the

boiler's electronics box, switch off the

power supply.

▶ Secure the power supply against being

switched on again.

▶ Do not carry out any work when the

(green) LED on the PCB of the product is

lit.

Danger!

Risk of damage caused by incorrect in-

stallation.

Connecting wires that have been stripped

too far may cause short circuits and damage

the electronics if a strand accidentally comes

loose.

▶ Only strip the outer sheathing of flexible

cables to a maximum of 2.5 cm to prevent

short circuits.

▶ Lay the lines correctly.
