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 Programmable Thermostat controls a
single heating system component such as a boiler, a
pump or zone valve. The factory conﬁ gured RF link
between the room unit and receiver makes the installa-
tion process fast and easy.
1. START UP
The 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.
1. Follow the installation diagrams to install and
connect the power supply to HC60NG relay
box. The RF system will commence normal
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.
2. To check the RF communication move the
CM67NG slider into OFF position (for CM61NG
press the OFF button) then press the TEMP
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
2. LOCATING THE CM67/61RF ROOM
1. Locate the room unit using the same test mode
as described in 1. START UP. Review the CM67/
61NG location guidelines (see installation diagram
) 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 Automatic Time Setting module attached).
2. Install the CM67/61NG on the wall using the wall
bracket or ﬁ t it on the optional table stand as shown
in installation diagram
NOTE: The HC60NG relay will be off.
3. Exit the TEST mode by moving the CM67NG
slider to the MAN or AUTO position (for CM61NG
press MAN or AUTO button).
IMPORTANT NOTE 2:
CM67/61NG can be used for two different applications
1. to control a single zone system
2. to control a multi-zone system.
If you intend to use it as deﬁ ned in point 1 -
read part A. SINGLE ZONE RF SYSTEM ﬁ rst
If you intend to use it as deﬁ ned in point 2 -
read part D. MULTI-ZONE RF SYSTEM ﬁ rst
HC60NG contains no user serviceable parts. It should
be opened and installed by qualiﬁ ed installer only.
Electrostatic sensitive device! Do not touch the circuit
a. Burner (direct control)
b. Combi boiler
c. Zone valve
NOTE: All wiring must be in accordance with IEE 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.
3. SYSTEM CHECK
1. Switch the boiler on
2. Move the CM67/61NG slider to AUTO or MAN
position(for CM61NG press the AUTO or MAN
3. Adjust the CM67/61NG setpoint up to the maxi-
mum (30°C) by pressing the TEMP
boiler should come on a few seconds after the
on 'ﬂ ame' symbol appears Check the system opera-
tion 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 communicate due to discharged bat-
teries). The factory setting keeps the relay permanently
off when communications is lost. If the factory setting
needs to be changed follow the instructions below:
1. Move the CM67NG slider into OFF position (for
CM61NG press the OFF button). Press and hold
the and PROG 3 & 4 buttons together.
2. Press PROG 2 button to enter category 2 param-
eters. Select the parameter 16:LC by pressing
+ or - button.
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.
- To enable the frost protection when RF com-
munication is lost select the fail-safe mode 1.
- For systems with separate frost protection thermo-
stat 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 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. Depend-
ing on the demand the HC60NG will switch the heating
(or cooling) device on to match the current require-
ments of the system.
d. Cooling device
CM67/61NG is a radio frequency device and for the best performance should
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
The HC60NG will also enter the failsafe mode as
selected in Installer's Mode (see 4. FAIL-SAFE MODE
To allow manual control of the HC60NG output manual
override is available in fail-safe mode. When RF com-
munication is restored the HC60NG will automatically
return to normal operation.
B. INSTALLER SET-UP MODE
Installer Set-Up Mode allows changing the controller parameters so it can meet speciﬁ c application requirements or customer's needs. See 4.
