NSTALLING THE AIR
TEMPERATURE PROBES

Position of the air temperature probe

This chapter is valid for ECFWEB6 controllers only (FWV
and FWL units). For ECFWER6 controllers, the probe is
integrated in the controller itself.
Use the plastic adhesive probe-holder supplied with the
controller.
Refer to the following figures for installing the air probe:
Unit without supporting feet (figure 13)
Unit with supporting feet (figure 14)
Unit with front air intake (figure 15)

Position of the water temperature probe

(white)
NOTE The standard wires connected to the
water probe (1.5 m) are not shielded.
These wires are only intended to be
used inside the unit and need to be
installed away from the power supply
cable. Always use shielded cable if the
water probe wires can not be installed
away from the power supply cables.
The water probe
shortened if required.
Always use shielded cable to lengthen
the water probe cable.
The specifications of the shielded
cable are as follows:
- maximum length: 100 m
- minimum section: 0.5 mm
- the shield must be connected to
of the basic unit. Do not
connect the shield on the
controller side in order to avoid
electromagnetic interference.
For the electrical connection, refer to
the appropriate wiring diagram.
Position for FWV FWL FWM
Use the special copper probe-holder for the water
temperature probe and install it as described below.
For 2-pipe system units without valve, the water
temperature probe has to be placed on the heat
exchanger (see figure 16 and figure 17).

For 4-pipe system units without valve, the water
AND WATER
temperature probe has to be placed on the heat
exchanger of the heating circuit. (See figure 18)
For 2-pipe system units with valve, the water
(black)
temperature probe has to be placed on the valve inlet
(on the branch coming from the system). (See
figure 19).
For 4-pipe system units with valve, the water
temperature probe has to be placed on the heating
valve inlet (on the branch coming from the circuit).
(See figure 20).

INTERFACE
The EPIMSA6 Master/Slave interface or EPIA6 Power
2
interface must be installed to use microprocessor-based
control panels on the whole range of units for models
with a current consumption greater than 1 A.
The EPIMSA6 Master/Slave interface is used for
connecting up to 4 units in parallel to 1 controller
(ECFWEB6 or ECFWER6). Up to 3 EPIMSA6
interfaces can be connected in parallel to 1 controller
(i.e. maximum of 12 units). The capacity of the
EPIMSA6 contacts is 4 x 3 A.
The EPIA6 Power interface permits to use the
electronic
ECFWER6) on the whole range of units with a
current consumption greater than 1 A. The capacity
of the EPIA6 contacts is 16 A.
