4.2.-

Communication between zone manager and boiler.

The box contains a MOD-BUS cable to communicate the zone manager, the boiler periphery and the
keyboard.
4.3.- Drive group installation.
When making hydraulic connections, it is highly recommendable to make them with mobile or quick
couplings to be able to disassemble any element for maintenance or replacement.
The drive group supplied by Ecoforest must be installed in an area close to the zone manager, taking into
account that it will be electrically connected to it.
The supply connections for the accelerator pump, motorized mixing valve and the NTC exit from the drive
group. These connections go in the zone manager. Check the electrical connections section.
It is highly important to respect the connections for zone 1, 2 and 3, that is, if we have 1 zone, make all the
connections for the pump, motorized mixing valve and NTC on zone 1 and so on.
In the event of having to extend the electrical connections, this must be carried out by welding the cables
and insulating them correctly with a vulcanized tube or vulcanized tape.
The rest of the installation will be according to the manufacturer's recommendations.
4.4.-

Room temperature control for each zone.

The Ecoforest zone manager offers the possibility of managing the temperature through a thT room
thermostat managed through MOD-BUS or through a room thermostat with a normally open voltage-free
contact (NO) when it cuts out by temperature. We have the possibility of connecting any contact as long as it
is voltage-free, be it, as mentioned previously, a closed contact to make a temperature demand or an open
contact to cut the temperature.
The contact room thermostat can be wired or wireless.

CONNECTIONS.

5.1.- On table 1 we have indicated the different nomenclatures of the connection terminal blocks.
5.2.- Scheme 1 (see following pages) indicates the connection between the boiler and the zone manager. The
supplied cable is 5 meters long. Its characteristics must be respected since it will manage communications
between both elements.
5.3.- The zone manager has the possibility of managing up to 3 zones, not being necessary to fully connect them.
Scheme 2 shows how to connect the zone manager to one of the impulse groups supplied by Ecoforest. The
connection of zones 2 and 3 would be carried out in the same way, having independent terminal blocks for
each zone (the contacts of zone 1, 2 and 3 are not shared)
scheme 3.
5.4.- Our zone manager has the possibility of managing the temperature of the zone, with a contact room
thermostat (normally open), either wired or wireless, scheme 4. In addition, it has the possibility of
connecting a thT thermostat in its wired version and communicated through a MOD-BUS cable. On this
connection is extremely important to respect the position of the cables.
5.5.- In scheme 5 we can see the assembly with 3 heating zones and with a different thermostat for each zone,
being in zone 1 a standard type wired room thermostat, with a normally open or closed contact. In zone 2 we
have a wireless room thermostat, although the receiver connection is identical to that of the wired
thermostat. In zone 3 a thT is connected, if we look at the connection it goes to another set of strips since, as
mentioned, it is extremely important to respect the connections.
5.6.- After connecting the zones and thermostats we must make the configuration in the web interface of our
boiler, for this we must read the user manual supplied with the boiler.
