NOTES ON RADIO TRANSMISSION
The control unit should preferably be located in a high place and away from metal masses and conductive elements.
The range between the thermostats and the control unit may be reduced if this is not the case.
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.

tween 0.75 mm2 and 1.0 mm2. If there are two regulators per zone (maximum recommended), connect them in parallel
2 System settings
Configuring the system is a two-step process:
1 Configure the switches of the ZITY control unit: Se lec t s wit ch S W1
ac co rd ing t o th e t yp e of m ac hin e an d po si tio n t he DI P8
in l ear ni ng m od e.
2 Link and configure the thermostats with the control unit
2.2 Configuration and connection of control interfaces
(only for Direct Expansion installations/VRF)
By default, the communication interfaces between the
ZONING System and the Direct expansion climate-
control units are factory-set. Only check the switches to
adjust the unit fan speeds and/ or in the case of remov-
ing the unit remote control. See the all switches configu-
ration of the corresponding interface manual.
The interface is connected to Rs485/LOC Bus, following
the indicated polarity.
For the connection between interfaces and the different
units, see the corresponding manual for each brand.
2.1 Configure the control unit switches: Consult for other applications.
The SW1 switch is used to configure the ZITY control unit according to the type of installation.
Dip 8 from SW1 8 is used to place the unit in learning mode during start-up (see the corresponding section).
2.3.A RC radio thermostat with ZITY-RC: Link the thermostats and the control unit via the following steps:
2.3 Link and configure the thermostats
Access the ZEUS/ ZOE-RC thermostats configuration menus to carry out the steps described. See the following diagrams:
· On the front label, locate the ID number (radio ID) of the ZITY control unit and
associate this number to each of the thermostats.
· Assign a zone number to each thermostat (corresponding to the motorized
control that has been connected to outputs 1 to 6 of the ZITY control unit.
· Select whether the thermostats is Master or Slave. A single thermostat must
be declared as a Master. If there is no Master or more than one, the ZITY con-
trol unit will be in error.
2.3.A ZOE-RC thermostats with ZITY-RC: After locating the corresponding radio ID of the ZITY-RC unit, assign a zone number to each
thermostat and select which thermostat will be MASTER or Slave.
key
2.3.B ZEUS-RC thermostats with ZITY-RC: Assign ID number / Zone / Master– Slave.
Learning and start-up: See section 3 to carry out this process.
2.3.B ZEBRA thermostats with ZITY-W (by wire)
1 Connect the thermostats and the control unit via the following steps:
· For the Master thermostat: define a single Master per installation.
Configure menus 5 (Master/ Slave), 6 (Flexifan), 9 (Actives Modes), 14 (Zone Number) and 16 (Keypad Lock):
For the Slave thermostat: Only configure menus nº5 (Slave) and nº14 (Zone number):
Valid values for the ZEBRA V2 (7 wires) in the case of having a ZEBRA V1 (4 wires) see the advanced setting.

3 Learning and start-up
In the first place, it is necessary to carry out the appraisal
process in order to detect all the system's elements and
start-up can be carried out later (once recognised).
Place the switches according to the type of the system (Direct
expansion, Fancoil, Boiler…). See page 11
Make sure that DIP 8 is OFF (up).
3.2 Exiting learning modeSalir del modo aprendizaje
1 Wait for 30 seconds after the last component has been
detected.
2 Pull down the DIP8 (ON).
3 Disconnect the voltage to the ZITY
control unit.
3.4 Learning and start-up for systems with zone expansion modules
The learning process should be carried out at the same
time in all the control units, main board (ZITY-RC or ZITY- W)
and expansion modules (ZITY-W/ME).
The SW1 DIP 8 should therefore be placed in learning
mode for all units (central and modules).
The LEDs for the associated zones will be enabled in each
control unit. The main board will detect, apart from the
zones, the expansion modules (LED R2 or LED R2/R3,
OFF).
* For RC systems, enter the ID for the main board in all
thermostats.
3.1 Recognising components
1. Connect the 230VAC power supply
of the ZITY control unit.
2. The control unit is positioned in
learning mode and the 7 LEDs
corresponding to the relays begin
to flash.
3. Every time the thermostat of one of
the zones is recognized by the
control unit, the LED for the zone
lights up in green.
The upper row of LEDs
corresponds to
peripheral detection.
Each time one of them
is detected, the
associated LED goes
out.
LED R1: Pasarela de comunicación máquina.
LED R2: Modulo de expansión 7-12 zonas
LED R3: Modulo de expansión 7-12 zonas
LED R4: Central combinada W-MC
LED R5: Central Slave 1
LED R6: Central Slave 2
LED R7: Central Slave 3
3.3 Start-up in normal operating mode
1 Connect the ZITY control unit again.
2 When power is supplied to the control unit, it will begin
to operate normally according to the settings specified
in the SW1.
3.5 Learning and start-up for systems with combined modules (…-MC). The learning process must be carried out on both
boards (the main one and the combined one), with the following particularities;
3.5.1 ZITY-RC/MC Combined modules: First, check that both
the base board (ZITY-RC) and the combination module
(ZITY-RC/MC) share the same ID.
The thermostats will be detected by both boards, the
gateway (...Box) will only be detected by the base board, and
the ZITY-RC/MC combined module will not be detected in
the relay LEDs although it will normally.
The learning process for the 2 control units can be carried out
at the same time or separately.
If the air and water climate control zones do not coincide,
consult the technical department.
3.5.2 ZITY-W/MC Combined modules:
Carry out the learning process simultaneously in both control
units, base board (ZITY-W) and the combined module (ZITY-W/
MC). The base board will detect the thermostats, the gateway
(…Box) if fitted, and the combined module (LED R4, OFF). The
combined module will not detect any component during this
process.
When starting for the first time in normal mode after learning,
the combined board WILL NOT turn on any LEDs until 3 min
have passed, and will then show the zone LEDs and the relays
that are active.
