GENERAL

2.2

Assembly, set-up and connection of on-board control panels

Assembly

The controllers have two independent clean contacts for

controlling a refrigerator unit, a boiler and a presence input.

The 2 tube versions have a 230V output to power the

summer and winter solenoid valve.

The 10 kΩ water temperature probe positioned in the

compartment on the battery regulations the minimum level

when heating (30°C) and the maximum level when cooling

(20°C).

The board also has a function when there is no water

probe, in such cases the fan stop thresholds are ignored.

Slide the control panel into its housing in the upper part

of the device and fix it with the two fixing screws (ref. A).

To install the connection box:

- open the box (ref. B);

- lock the lower tooth into its hole (ref. C) on the side of

the device;

- hook the upper part of the box to the side (ref. D);

- fix it with the two fixing screws (ref. E);

- connect the grounding cable to the fan coil body (ref. M)

using the fixing screws (the minimum force that must be

applied for tightening screws must be around 2N);

- connect the fast connector of the MOTOR to the other

on the board (ref. I) *;

- on the two GRID block terminals (ref. L) there is a

bridge that allows the FWXM-series to work without a

microswitch.

- For other versions, remove the bridge and connect the

two terminals originating on the grill safety microswitch*;

- connect the water probe to the H2 connector on the

device.

The water temperature probe controls the temperature

inside the batteries and determines when the fan starts

according to pre-set parameters (minimum operation

in winder and maximum in summer).** Check that

they are correctly inserted into the compartment on

the battery.

- Connect the electrics, tidy cables and fix them with

the three clevises supplied (ref. G);

- close the box with the 4 screws (ref. H);

- refit the vanity plate on the side of the unit;

- tighten the upper screws on the control panel;

- place the screw head covers in their housing on the

control panel;

* For versions with hydraulic connections on the right,

refer to the relevant paragraph

** The regulation also works without a water probe

connected

2.4

There are two dip switches on the controller circuit board

for configuring unit operation as per requirements.

- The night-time heating operation logic is modified by

using dip switch C:

- in the ON position, the fan is always off, and heats the

room using radiation and natural convection, as with

traditional radiators; in the off position it operates as a

normal fan.

- By positioning dip switch B to ON, when cooling, the

fan operates at the minimum speed even after having

reached the set point, to allow for more uniform

operation of the temperature probe and to avoid

layering in the air. With the cursor in the OFF position,

the functions are cycled (4 minutes ON, 10 minutes

OFF).

On closing the contact connected to the CP input (ref. A)

the panel is placed in stand-by mode.

If the contact is open the unit is active, if the contact is

closed it is deactivated when a key is pressed the

symbol flashes.

The input cannot be connected in parallel to that of other

electronic boards (use separate contacts).

- To position the temperature probe (ref. A):

- pass the probe through the hole on the shoulder (ref. B)

- insert the probe into the lower hole (ref. C)

Continuous modulation circuit board for connecting remote thermostat

LED Indications (Ref. A)

EKWHCTRL0

The circuit board for remote control is for all functions of

the fan coil system from the wall-mounted remote control

EKWHCTRL0.

A remote control can be connected to a maximum of

30 fan coils that will be controlled in broadcast mode

(simultaneous commands to all fan coils).

It can be installed on all versions, the board has a green

LED that indicates the operational state and any anomalies.

The main operational parameters, the set point and the

room temperature are transmitted from the wall-mounted

remote control EKWHCTRL0 to all terminals connected to

the network, allowing unified operation.

Refer to the instructions for this control for use of the fan

coils.

The 10 kΩ water temperature probe positioned in the

device battery regulations the minimum level when heating

(30°C) and the maximum level when cooling (20°C).

Green LED: Indicates that the unit is

operational. Flashing indicates an anomaly. LED off: unit is off or has no power.

Error signals

Error Display

Communication error. The circuit board expects continuous information exchange on the serial line

with the wall-mounted control EKWHCTRL1. If this exchange is lost for more than 5 minutes, an

error warning is displayed and the unit deactivated.

6 flashes + pause

Problem with fan motor (e.g. blockage caused by foreign objects, faulty rotation sensor). 2 flashes + pause

Water temperature probe fault (H2).

In this case, ensure that the probe installed is 10 kΩ. 3 flashes + pause

Engaging of grille microswitch S1 due to filter cleaning operation. Continuous rapid

flashing

Water demand detected by probe H2 insufficient (above 20°C when cooling, below 30°C when

heating). Stops the fan until the temperature returns to a suitable level to satisfy the demand*. 1 flashes + pause

* If after having powered the board the water probe is

detected, start-up takes place with the minimum and

maximum water temperature thresholds.

The board also has a function when there is no probe, in

such cases the fan stop thresholds are ignored.

conditions with the minimum water temperature

when heating (30°C) and maximum when

cooling (20°C).

The board also has a function when there is no

probe, in such cases the fan stop minimum and

maximum thresholds are ignored.

Rigid or flexible wires with a 0.2 to 1.5 mm² cross-section

(0.75 mm² if two wires are connected to the same terminal

block) can be inserted in the 4 spring-loaded terminal

blocks (ref. A) for connection of the wall-mounted controller

EKWHCTRL1. If the wires have wire end ferrules with a

plastic collar, the maximum cross-section is 0.75 mm².

Strip 8 mm of the wire, then if the wire is rigid, you can

insert it easily whereas, if it is flexible, it is advisable to use

long nose pliers.

Push the wire completely in and check that it is anchored

by pulling it gently.

To disconnect the cables, press the

corresponding white indent (ref. A) with a

screwdriver and remove the conductor.
