Honeywell CM67NG Installation Manual

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-
munication protocol
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
in the CM67NG or 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
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.
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
8. BINDING.
2. LOCATING THE CM67/61RF ROOM
UNIT
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
10
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 .
11
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
or
2. to control a multi-zone system.
If you intend to use it as defi ned in point 1 -

If you intend to use it as defi ned in point 2 -

NOTE:
HC60NG contains no user serviceable parts. It should
be opened and installed by qualifi ed installer only.
WARNING:
Electrostatic sensitive device! Do not touch the circuit
board.

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
button)
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
buttons.
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 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.

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
button. The
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 com-
munication is restored the HC60NG will automatically
return to normal operation.
B. INSTALLER SET-UP MODE
or
Installer Set-Up Mode allows changing the controller parameters so it can meet specifi c application requirements or customer's needs. See 4.
INSTALLER SET-UP MODE TABLE for detailed list of confi gurable parameters.

8. BINDING
The binding operation described below is required if:
- any of the system components (room unit or relay
box) are replaced
- 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 HC60NG.
1. 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.
2. 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.
3. Move the CM67NG slider to the OFF position (for
CM61NG push the OFF button) and press the
TEMP ,
CM67/61NG will display InSt
4. Press the button to send the binding signal. The
red LED is switched off to confi rm successful bind-
ing operation. If red LED still fl ashes push the
button again until binding is successful.
5. Follow the START UP and other procedures to
commission the single zone RF system.
