D. MULTI-ZONE RF SYSTEM (READ THIS SECTION ONLY IF YOU USE CM67/61NG TO CONTROL A MULTI-ZONE SYSTEM)
NOTE: Before commencing installation make sure that the
hydronic layout of the heating system is suitable for zoning.
CM67/61NG is designed to be able to control multi-zone systems
where heat transfer to the individual zones is controlled by means of
zone valves or pumps (see Fig. 1).

Fig.1 Multi-zone System Plan
The HC60NG zone controllers operate zone valves or pumps. The
CM67/61NG room units located in every zone provide heat demand
signal for each zone controller. The HC60NG boiler controller operates
the boiler. It is collecting the demand signals from all room units to
make sure that the boiler delivers enough heat to satisfy every zone.
To set up a multi zone system you will need:
- one
CM67NG or
CM61NG system pack per zone in the installa-
tion. The system pack contains one room unit (transmitter) and one
zone controller (receiver)
- one HC60NG boiler controller
Fig.2 Marking the room unit and the zone controller as a pair.
1. START-UP (max. 4 zones)
1.
Mark the room units and relay boxes (zone controllers) from
system packs using
1
,
2
,

,

labels supplied (see Fig.2).
Leave the HC60NG boiler controller unmarked.
NOTE: It is important not to mismatch the pairs from the system
pack boxes as they are already pre-bound. Keeping them in pairs
will speed up system set-up. The HC60NG from the system packs
work as zone controllers (controlling the zone valves or zone
pumps), the HC60NG delivered separately will work as the boiler
controller (see Fig.1)
2.
Install and wire up all the zone controllers following the installation
guidelines, zoning system plan (see Fig.1) and wiring diagrams.
NOTE: Do not connect power supply to the boiler controller.
3.
Remove the insulation tabs from the room unit battery compart-
ments (see installation diagram

)
4.
To check the factory pre-set RF link between the room unit and
zone controller, move the CM67NG slider into OFF position (for
CM61NG press the OFF button) and press TEMP
,
PROG 2 buttons together for 3 sec. The unit will display tESt and
it will send test signals, The zone controller 1 will start switching
green LED on and off every 5 sec (the relay output will remain
off)
5.
Exit the test mode by moving the slider into AUTO position (for
CM61NG press the AUTO button)
NOTE: If green LED is not switched on and off at specifi ed
intervals, follow the procedure described in Part A. section 8.

2. SYSTEM SYNCHRONISATION
One of the room units has to be set up to govern the synchronisation
of all zones. To confi gure room unit
as system synchroniser follow
1
the procedure below:
1.
Enter the installer's mode of the room unit
to the OFF position (for
CM61NG press the OFF button) and
pressing the PROG 3, 4 and buttons together
2.
Press the PROG 2 button to enter the category 2 parameters.
Select parameter 9:Sn by pressing
+ or - button
3.
Set the 9:Sn parameter value to 1 by pressing the TEMP
button. Confi rm the selected value by pressing the button
NOTE: Only one room unit can be confi gured as the system
synchroniser.
4.
Move the
CM67NG slider to AUTO or MAN position (for
CM61NG press the AUTO or MAN button to exit the installer mode.
5.
To check if the room unit
is confi gured as the synchroniser
1
press the button twice. The unit will display the time and Sn
NOTE: If the Sn is not displayed repeat instructions above
6.
Using the room unit
confi gured as the synchroniser, enter the
1
synchronisation binding mode by moving the
the OFF position (for
CM61NG by pressing the OFF button) and
pressing the TEMP
,
and PROG 6 buttons together. The
CM67/61NG will display InSt Sn
7.
To enter the binding mode, press and hold the push button of the
HC60NG zone controller
for 5 sec (until the red LED starts
2
fl ashing at 0.5s on/0.5s off).
NOTE: It is not required to bind the room unit
controller
as they are already factory bound.

8.
Press the button of the
CM67/61NG synchroniser room unit to
send the timing binding signal. After successful binding operation
the red LED will be switched off If red LED still fl ashes push the
button again until binding is successful.
9.
If you set-up a system with 3 or 4 zones, repeat steps 7 and 8 with
HC60NG zone controllers for zone 3 and 4
10. Exit the synchroniser binding mode by moving the slider to AUTO
or MAN position (for
CM61NG by pressing the AUTO or MAN
button)
3. BINDING THE ROOM UNITS TO THE BOILER
CONTROLLER
To provide the heat demand signal from individual zones to the boiler,
each zone room unit has to be bound to the boiler controller
1.
Install and wire-up the HC60NG boiler controller. The red LED will
fl ash 0.1s on/0.9s off.
NOTE: If it is not fl ashing as described above, press and hold the
push button for 15 sec to remove any stored binding data from
the memory.
2.
Press and hold the push buttons of the boiler controller for 5 sec
to enter the binding mode. The red LED will start fl ashing at 0.5s
On/0.5 s Off. HC60NG is ready for binding
3.
Move the slider of the
CM67NG
1
to OFF position (for
CM61NG

press the OFF button). Press the TEMP
and PROG 1 button together. The
CM67/61NG will display InSt
and
4.
Press the button to send the binding signal to the HC60NG boiler
controller. After successful binding operation the red LED will be
switched off. If red LED still fl ashes push the button again until
binding is successful.
5.
Move the
CM67NG slider to AUTO or MAN position (for
CM61NG press the AUTO or MAN button to exit the binding mode.

the OFF button) and push the TEMP
together to enter the RF communication test mode. The room unit
will display tESt
1
by moving the slider
2.
The room unit will start sending RF signals switching the green
LED of the HC60NG's on and off every 5 seconds for 10 minutes.
NOTE: All the HC60NG relays will be off.
3.
Review the RF Communication Check Table to establish which
or
HC60NG should react to the test signals of the room unit
4.
Observing the room unit location guidelines (Fig. 9) fi nd suitable
location for the room unit where RF communication is reliable.
5.
The reliable communication is indicated when all appropriate
HC60NG's (see RF COMMUNICATION CHECK TABLE) are
switching the green LED every 5 seconds.
6.
Install the room unit in the selected location following
Installation Guide (alternatively use the optional table stand).
7.
Repeat the testing procedure with all the room units in the system.

6. FAIL-SAFE MODE SET-UP
The failsafe mode selected defi nes the HC60NG output relay status
if the RF communication is lost. The factory setting keeps the relay
to the zone
permanently off when communications is lost. If the factory setting
1
needs to be changed follow the instructions below:
1.
Move the
CM67NG slider into OFF position (for
press the OFF button). Press and hold the and PROG 3 & 4
buttons together.
2.
Press the PROG 2 button to enter the category 2 parameters.
Select the parameter 16:LC by pressing
3.
Select the fail-safe mode by pressing TEMP
0 - when RF communication is lost the relay will be held in OFF
position
1 - when RF communication is lost the relay output will cycle at
20% on 80% off
IMPORTANT:
- To enable the frost protection when RF communication is lost
select the fail-safe mode 1
- For systems with separate frost protection thermostat or where
frost protection is not required select fail-safe mode 0
4.
Confi rm the selected value by pressing the button
5.
Attach appropriate label to the HC60NG to indicate the selected
fail-safe mode.
NOTE: You can set fail-safe mode operation individually for each zone.

more heat is required. Depending on the demand signal the HC60NG
will switch the heating device on to match the current requirements
of the system.

Green LED off - relay off
The green LED indicates status of the relay output.
8. TEMPORARY MANUAL OVERRIDE
Pressing the HC60NG button will override the current relay position.
As soon as next signal is received from the room unit the HC60NG
will return to automatic operation as the automatic control has higher
priority than manual operation
9. COMMUNICATION LOSS
When the RF communication is lost for a period of 1 hour the red
LED will be switched on to indicate that no RF messages have been
received during the last hour.

10. SYSTEM PARAMETERS CONFIGURATION
The key parameters of the boiler control algorithm are set centrally
at the unit confi gured as the system synchroniser. The following param-
eters of the synchroniser unit will be used for boiler control:
Parameter
- minimum on time:
+ or - button.
- cycle rate
or

If no modifi cations to the values of these parameters are made the
default values apply (see part B. INSTALLER SET-UP MODE).
For detailed information on setting Installers parameters refer to part B.
