NOTES ON RADIO TRANSMISSION
The central control unit should preferably be located in a high place and away from metal masses and conductive
elements. Otherwise, the range between the thermostats and the central control unit may be reduced.
Radio transmission does not take place on an exclusive frequency, so the possibility of interference cannot be
excluded. Frequency inhibitors and radio equipment operating in a permanent transmission mode in the same
frequency band (433 MHz) may impair the normal operation of the ZONING. The system is designed to work on two
different frequencies (433.92 and 434.33 MHz) to minimise this type of problem.
The installation should be carried out by authorised personnel only. Perform the entire
installation without supply voltage. Protect the equipment with the usual devices.

1 System description
The ZONING system is made up of a set of regulating
devices for temperature control in up to 18 separate zones
in centralised air conditioning and/or heating installations.
Control is achieved through a central control unit
connected to digital thermostats and motorised valves
(gate valves), installed in each of the areas to be climate-
controlled.
This central control unit regulates the temperature in each
zone acting on the relevant gate valves and the air
conditioning and/or heating unit. At the same time, the
system central control unit allows interaction with other
devices in the installation (home automation, digital input,
WIFE connection, etc.).
1.1 ZITY central control unit ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
Electronic control device for surface mounting, designed for
air condition and heating equipment from 2 to 18 areas.
ZITY can control direct expansion units, hydronic fan coils
and radiant floor or radiator heating systems.
Communication with the zone thermostats can be via radio
or wired, depending on the thermostat. It has 2 RS 485
communications ports, one local and the other remote,
which make integration possible in building management
systems.
Fig. 1 ZITY central control unit

supply wires should be connected (orange/ blue: 12VDC)
and the 2 communication wires (red/black), according to
the diagram opposite.
2.5. Production equipment and NTC probes ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
The ZITY zoning system is compatible with climate-control
installations via air ducts (direct expansion or Fan coil) and
hybrid systems with air conditioning and heating by
radiators.
The interconnection between the central control unit and
the production equipment varies according to the type of
installation, the combination between them and the
functionalities required by the user.
In addition, the ZITY central unit has 2 sensor inputs (NTC
1 and NTC 2), whose function depends on the production
equipment installed:
•NTC 1: return air temperature sensor in direct
expansion installations or water intake temperature

The internal unit control is not mandatory but it is advisable
to install it as an alarm display for the air conditioning
equipment.
2.5.A.2. ON/OFF direct expansion equipment
In older units that are not compatible with the interfaces,
the unit control relays can be used for remote start/stop.
The functionalities and output of the zoning system without
interface are lower than those of systems that do have it,
but they allow basic control of the air conditioning
equipment.
Fig. 18 Standard installation diagram for equipment without interface
See the connection diagram for each brand and model. It is
mandatory to install the internal unit control for controlling
the operating mode and setpoint temperature of the
equipment.
The NTC2 sensor is used for safety reasons and it is only
mandatory to install it in electromechanical equipment. In
all other cases the heating element that comes by default
from the factory can be left in place.

To do this, use the DIP 5 of
SW1 of the ZITY central
control unit.
Each internal unit is
connected to the
corresponding ZITY
central control unit, as in
the direct expansion
equipment with interface.
In this case any internal
Unit of the VRF system is
able to impose the mode.
In this application all ZITY
central control units con-
nected to each internal
unit should be configured
as VRF Master.

2.5.B.2. Combined heating / direct expansion hybrids
In this application it is possible to control a conventional
heating system and at the same time an air conditioning
unit by direct expansion with Interface, integrating in a
single type of thermostat all the functionalities of both
systems separately.
Two ZITY central control units are installed, one to control
the direct expansion unit (with or without gateway) and the
other to control the heating system by radiators or radiant
floor.
Both central control units are joined by a Communication
Bus, which manages either central control unit depending
on the operating mode (Cold/heat by air, or radiant heat).
The first one is defined as the Master Central Control Unit
and the second one as Slave.
The NTC sensors have the functionality of each of the
production equipment separately.

2.5.C. Hybrid aerothermal heating / water-operated air conditioning equipment
The same installation can combine water-operated heating
systems with radiators and/or radiant floor and fan-coils
with ducts for controlling air conditioning and/or air-
operated heating.
2.5.C.1. Water-operated heating and 3v Fan-coil with 2 pipes
Two ZITY central control units are installed, one for
controlling the Fancoil with ducts by zone and the other for
the heating system by radiant floor or radiators.
As in the previous case, the board that controls the fan-coil
is configured as the MASTER and the one that controls the
heating is configured as the SLAVE. With this configuration
the MASTER is the one that acts on the internal Unit of the
Aerothermal equipment to produce the ON/OFF and also
set the operating mode. This control takes place via 2
voltage-free contacts. Consult the wiring diagram for each
Aerothermal brand and model.
Consult Madel for other Aerothermal applications and

3 System configuration
The system configuration consists of two steps:
1Connect the thermostats to the central control unit and
the corresponding zone
2Configure the switches of the ZITY central control unit
according to the type of installation
3.1. Connect the thermostats
This consists of associating each thermostat
with the central control unit (with the
identification number ID of the central control
unit) and assigning it a zone number
(corresponding to the motorised gate valves
connected to outputs 1 to 6 of the central
control unit).
These operations will be carried out via the
settings menus of each thermostat, as
indicated below. You can find additional
information in the thermostat instruction
manuals.
