) in the 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).
D. MULTI-ZONE RF SYSTEM (READ THIS SECTION ONLY IF YOU USE CM67/61NG TO CONTROL A MULTI-ZONE SYSTEM)
Fig.2 Marking the room unit and the zone controller as a pair.
Fig.1 Multi-zone System Plan
NOTE: If you replace any of the components of the multi-zone control
system, it is recommended to follow all procedures described in Part. D
C. TROUBLE SHOOTING GUIDE
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
1. START-UP (max. 4 zones)
1. Mark the room units and relay boxes (zone controllers) from
system packs using
1
,
2
,
3
,
4
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
7
)
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 , and
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.
BINDING.
6. Repeat steps 4 and 5 for every room unit and zone controller pair
in the system.
Symptom (Fault Message)
The room unit displays the
symbol but the relay does not
switch on
The HC60NG zone controller
does not react to setpoint
changes on the room unit
After binding procedure the red
LED is on and the green one is
fl ashing once every 3 sec
The red LED is on (Communica-
tion loss)
After procedure described in part
D. section 3.BINDING THE
ROOM UNITS TO THE BOILER
CONTROLLER the red LED is
on and the green one is fl ashing
twice every 3 sec.
After procedure described in part
D. section 2.SYSTEM
SYNCHRONISATION the red
LED is on and the green one is
fl ashing 3 times every 3 sec.
After procedure described in part
D. section 2.SYSTEM
SYNCHRONISATION the red
LED is on and the green one is
fl ashing 4 times every 3 sec.
The red LED is fl ashing 2.5 sec
on - 2.5 sec off (Communication
loss)
Possible Cause
This is normal operation. The room unit
sends only the demand signal (0-100%) to
the relay box. Depending on the demand
signal the relay box will switch the relay on
when required
The room unit and receiver are not bound.
Incorrect or incomplete binding procedure
Incorrect position of the room unit during
binding
The relay box receives no RF messages
from
CM67/61NG:
RF signal is blocked due to wrong location
of the room unit
Room unit batteries are exhausted
An attempt was made to bind more than 4
room units with the boiler controller
An attempt was made to bind the HC60NG
with system timing message when no
demand binding information is present
An attempt was made to bind two system
timing masters with one receiver box
The relay box is missing signals from
one (or more)
CM67/CM61NG but still
receives messages from other room units:
RF signal is blocked due to wrong location
of some room units in the system
Room unit batteries are exhausted
Remedy
Using TEMP button change the temperature setpoint by
a few degrees. The receiver should switch the relay on after
a few seconds delay
Reset* the HC60NG zone controller and follow the binding
procedure as described in part A. section 8 BINDING
Repeat the binding procedure
Repeat the binding procedure keeping approx. 1 m distance
between the HC60NG and
CM61/67NG
Re-locate the room unit(s) following instructions in:
Par t A. section 2. LOCATING THE CM67/61 NG ROOM UNIT
or Part D. section 4.LOCATING THE ROOM UNITS
Replace batteries in the room unit
Reset* the HC60NG boiler controller, repeat the following
binding procedures:
Par t A. section 8.BINDING
Par t D. section 3. BINDING THE ROOM UNITS TO THE
BOILER CONTROLLER
Reset* HC60NG zone controller, repeat the following binding
procedures:
Par t A. section 8.BINDING
Par t D. section 2. SYSTEM SYNCHRONISATION
The above listed operations should be repeated ONLY for the
receiver which displayed the fault message
Make sure that only one room unit in the system is confi gured
as synchroniser. Reset all the HC60NG’s in the system.
Bind matching room units with the zone controllers (1 with 1,
2 with 2, …) as described in Part A, section 8.BINDING

7. AUTOMATIC OPERATION
HC60NG receives the heat demand (0-100%) signal from one (or
more)
CM61/67NG. The room unit will display the symbol whenever
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 on - relay on
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.
The HC60NG will also enter the failsafe mode as selected in Installer’s
Mode (see 6. FAIL-SAFE MODE SET UP).
Red LED fl ashing at 2.5s on/2.5 sec off - if messages from one of the
room units is lost but the HC60NG still receives signals from others
units it is bound to.
The fail-safe mode operation depends on the HC60NG confi guration
and its function in the system:
- HC60NG boiler controller: Fail-safe mode/0 confi gured in all room
units => relay OFF
Fail-safe mode/1 confi gured in any
of room units => relay cycling 20%
ON/80% OFF
- HC60NG zone controller Fail-safe mode/0 confi gured in the
zone room unit =>relay OFF
Fail-safe mode/1 confi gured in the
zone room unit => relay ON
When the HC60NG does not receive the synchronising message it will
indicate the communication loss status (red LED fl ashing at 2.5s on/2.5
sec off) It will operate using the available heat demand information.
The system synchronisation may be lost and consequently tempera-
ture control performance will become unsatisfactory. See section C.
TROUBLE SHOOTING GUIDE for possible cause and remedy.
For the set-up of the fail-safe mode see 6. FAIL-SAFE MODE SET-UP.
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:
4. LOCATING THE ROOM UNITS
