IMPORTANT NOTE 1:
CM60RFNG room unit and HC60NG receiver operate
on 868MHz frequency. They will not communicate with
other RF products using different frequency or com-
HC60NG is a Radio Frequency (RF) device. For the
best performance install in an open space. Leave at
least 30cm distance from any metal objects including
wall boxes and boiler housing.
Do not mount on metal wall boxes.
Once you have inserted the battery compartment,
after a pause the unit will display information. If this
does not happen or the display shows the
symbol please refer to the 'trouble shooting' section
CM61NG user guides.
A. SINGLE ZONE RF SYSTEM
CM67/61NG Chronotherm controls a single heating system compo-
nent such as a boiler, a pump or zone valve. The factory conﬁ gured RF
link between the room unit and receiver makes the installation process
fast and easy.
1. START UP
CM67/61NG room unit is factory bound with the HC60NG relay
box. Therefore no initial binding between the room unit ( CM67/61NG)
and receiver (HC60NG) is required.
Follow the installation diagrams to install and connect the
power supply to HC60NG relay box. The RF system will com-
mence normal operation immediately.
NOTE: If the red LED is ﬂ ashing or if you install a replacement
relay box or room unit, please follow the procedure described in
section 8. BINDING before system START UP.
To check the RF communication move the
CM67NG slider into
OFF position (for
CM61NG press the OFF button) then press the
and PROG 2 buttons for 3 seconds. The unit will
display tESt and it will send test signals to the receiver switching
the green LED on and off every 5 seconds (relay output will remain
off) for a maximum of 10 minutes. When the green LED ﬂ ashes
on/off every 5 seconds proceed to the next step.
NOTE: If the green LED is not switched at speciﬁ ed intervals follow the
procedures described in section 8. BINDING.
2. LOCATING THE CM67/61RF ROOM UNIT
Locate the room unit using the same test mode as described in
1. START UP. Review the
CM67/61NG location guidelines (see
) and ﬁ nd a suitable location where the
signal transmission is reliable. Reliable transmission is indicated
when the HC60NG relay box is switching the green LED every 5
seconds. (if the accessory module is applied the room unit must be
located with the module attached).
CM67/61NG on the wall using the wall bracket or ﬁ t it
on the table stand as shown in installation diagram
NOTE: The HC60NG relay will be off.
Exit the TEST mode by moving the
CM67NG slider to the MAN
or AUTO position (for
CM61NG press MAN or AUTO button).
3. SYSTEM CHECK
Switch the boiler on
CM67/61NG slider to AUTO or MAN position(for
CM61NG press the AUTO or MAN button)
CM67/61NG setpoint up to the maximum (30°C) by
pressing the TEMP
button. The boiler should come on a few
seconds after the on 'ﬂ ame' symbol appears Check the system
operation changing the setpoint several times, bearing in mind the
switching delay already referred to.
4. FAIL-SAFE MODE SETUP
The failsafe mode selected deﬁ nes the HC60NG output relay status
if the RF communication is lost (e.g. when room unit stops to com-
municate due to discharged batteries). The factory setting keeps the
relay permanently off when communications is lost. If the factory setting
needs to be changed follow the instructions below:
CM67NG slider into OFF position (for
press the OFF button). Press and hold the and PROG 3 & 4
IMPORTANT NOTE 2:
CM67/61NG can be used for two different applications
1. to control stand alone heating device (e.g. boiler,
pump, zone valve).
2. as a part of multi-zone control system.
If you intend to use it as deﬁ ned in point 1 - read part A.

If you intend to use it as deﬁ ned in point 2 - read part D.

HC60NG contains no user serviceable parts. It should
be opened and installed by qualiﬁ ed installer only.

f. Electric heater
NOTE: Install in accordance with local wiring regulations
CAUTION: Observe ambient temperature and current limits (see HC60NG wiring label)
be installed in an open space. Leave at least 30cm distance from any metal objects
including wall boxes and at least 1 metre from any other electrical equipment eg.
radio, TV, PC etc. Do not mount on metal wall boxes.
It is recommended that the HC60NG relay box is installed before commencing with
the Room Unit installation.
Press the PROG 2 button to enter the category 2 parameters.
Select the parameter 16:LC by pressing
Select the fail-safe mode by pressing TEMP
0 - when RF communication is lost the relay will be held in OFF
1 - when RF communication is lost the relay output will cycle at
20% on 80% off.
- 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 .
Conﬁ rm the selected value by pressing the button.
Attach appropriate label to the HC60NG relay box to indicate the
selected fail-safe mode.
5. AUTOMATIC OPERATION
HC60NG receives the heat (or cool) demand (0-100%) signal from
CM61/67NG. The room unit will display the symbol whenever more
heat is required. Depending on the demand the HC60NG will switch
the heating (or cooling) device on to match the current requirements
of the system.
The green LED indicates status of the relay output.
Green LED on - relay on
Green LED off - relay off
6. 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 back to automatic operation as the automatic control has higher
priority than manual operation
7. 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 4. FAIL-SAFE MODE SET UP).
To allow manual control of the HC60NG output manual override is
available in fail-safe mode. When RF communication is restored the
HC60NG will automatically return to normal operation.
The binding operation described below is required if:
- any of the system components (room unit or relay box) are
- HC60NG has incorrect or no binding data stored (e.g. when
pre-bound system pack components have been mismatched)
During the binding procedure keep approximately 1m distance
between the room unit and the relay box.
Press and hold the HC60NG push button for 15 sec to reset
previously stored data. The red LED will start to ﬂ ash at 0.1 s
on/0.9 s off. Release the push button.
Press and hold the HC60NG push button for 5 sec to enter the
binding mode. Red LED ﬂ ashing at 0.5s on/0.5 s off conﬁ rms the
binding mode has been entered.
CM67NG slider to the OFF position (for
push the OFF button) and press the TEMP
1 buttons together
Press the button to send the binding signal. The red LED is
switched off to conﬁ rm successful binding operation. If red LED
still ﬂ ashes push the button again until binding is successful.
Follow the START UP and other procedures to commission the
single zone RF system.
