2-wire mounting
●

RL 1
R
RL 2
This is the simplest way, but line resistors (RL1 and RL2) are connected to the sensor in a series circuit.
The addition of RL1 + RL2, leads to an off-set between measured temperature and real temperature. This
connection must be avoided.

3-wire mounting
●

This connection involves identical line resistors (RL1-RL2-RL3), RL2 + RL3 allow you to measure the line
resistance that will be subtracted from the measured resistance between 1 and 22' terminals. This is the
most common connection.

To mount the transmitter, mount the ABS plate on the wall (drilling : Ø6 mm,
screws and pins are supplied).
Insert the transmitter on the fixing plate (see A on the drawing beside). Rotate
the housing in clockwise direction until you hear a “click” which confirms that
the transmitter is correctly installed.

Ambient model has not any fixing plate.
4 fixing holes are inside the back housing. Use them to install the transmitter on the
required location.
The contact model is fixed with 2 mounting brackets supplied with the transmitter.
