Honeywell thermostat CM67RF 7 Day Wireless Programmable Thermostat User Manual

							What is an RF Chronotherm?A Honeywell Radio Frequency (RF) communicating Chronotherm is a
programmable thermostat that controls your heating system so that
you can have comfortable temperatures when you are at home and
energy savings when you are out. With RF communication there is no
need to provide wired connection between thermostat and boiler. The
Chronotherm can therefore be installed without disrupting your room
decor. Instead of wired connection the Chronotherm sends a radio
frequency signal directly to the relay box installed next to the boiler.
These instructions explain how to program and operate your
Chronotherm to get the most comfort at the least cost.What will the 
CM67NG Chronotherm do for me?

Wireless connection to the boiler allows you to mount the
Chronotherm in your room without decor disruption

Armchair programming feature lets you program your
Chronotherm while resting comfortably in your armchair

Attractive slim styling makes it ideal for location in any room in
your home

7 day program lets you set the 
CM67NG to match your weekly
lifestyle

6 daily independent temperature levels let you set any 6
temperatures from 5 to 30°C at any time each day, to match your
daily lifestyle

Party button  lets you temporarily maintain (or adjust) the current
temperature for 1 - 23 hours. Useful when you have friends round
or go out of the house for a short while

Day Off button copies Sunday’s program into tomorrow so that
you can make the 
CM67NG follow the Sunday program if you
have a day off during the week

Holiday button saves energy by letting you reduce the tempera-
ture for 1 to 99 days while you are on holiday, returning to normal
operation on the day you return

Memory holds the user program indefinitely so that it is never lost
even if you remove the batteries
How do I install the batteries?1. Lift up the front flap to reveal the battery compartment. Open the
battery compartment by inserting a coin underneath the bottom
right edge of the flap and lift it out.
2. Pull the paper tab out to activate the 2 AA LR6 Alkaline Batteries
included and push the battery compartment firmly back into the
front of the unit. After a pause the unit will now display information.
RF Chronotherm
Automatic Time Setting (ATS) “Add-On” Module *The ATS module picks up a daily time signal from a transmitter in
Central Europe and corrects the time on the RF Chronotherm display.
So:
You never need to set or adjust the time

There is no need to adjust the unit by -/+ 1 hour in summer / winter
since the unit does this automatically

Your Chronotherm is the most accurate clock in your home so you
can use this information to set-up all your other clocks.
* Not available in all Geographic Regions depending on transmitter
range and home location.
Can I use my Chronotherm to control my air-
conditioning system?Yes. Please refer to your installer for more information.

When do I need to use the push button?During the normal system operation there is no need to use HC60NG
push button. You can control your boiler manually using yourCM67NG room unit:
1. Move the slider to the MAN position
2. Switch the boiler ON or OFF by pressing the TEMPerature 
 or
 button to increase or decrease the programmed temperature.
You should use the push button to control your boiler only when the
radio 
frequency communication is lost (see the 
CM67NG Trouble-
Shooting Guide).
Multi-zone Heating SystemsHow can I enhance comfort and save energy
with Honeywell RF multi-zone system?We are quite used to switching the lights on in our houses using
individual switches in every room. It is common that we even use more
than one light switch to control the lights in the room. Yet we still expect
that one room thermostat will control heating in the entire house,
providing comfort for all inhabitants and maximum energy efficiency of
the heating system. Certainly just one room thermostat can not meet
these requirements. To address the needs of modern households,
Honeywell developed 
CM60NG – simple and practical heating
controller for up to 4 zones.
Why do I need a multi-zone system?We can all distinguish at least two functional zones in our houses. A
day time zone, where we spent our time when we are active and the
night zone where we sleep. Sometimes we can define more zones e.g.
study zone or teenager’s zone. This functional division of the house
into zones dictates the need for different temperatures at different
times of the day. Therefore our heating control system should allow us
to set and program temperatures individually for each zone.
What is required to install a zoning system?First, your heating system has to be laid out in a way that allows
control of the heat supply to a zone by means of zone valves or pumps
(see drawing, ask you installer for details).
If this condition is fulfilled the rest is easy. Ask your installer to add
additional zone controller(s) and a boiler controller.
Is the Honeywell zoning system easy to use?It is very easy to use. In fact it is just an additional room unit exactly
the same as standard 
CM60NG. As the system is using RF commu-
nication you do not have to install the room unit on the wall in the
second zone. Just mount it on the table stand and find suitable location
where the communication is always reliable.
What are the benefits of installing Honeywell
multi-zone system?- Enhanced comfort - you can now control temperature individually
in each zone
- Improved efficiency of your heating system – your multi-zone RF
system will save energy delivering heat only to the zones, which
really require it.

							How do I know when the batteries need changed
and how do I change them?Your RF Chronotherm has built-in electronics that constantly monitor
the battery power level. With no other accessories fitted the batteries
should last about 3 years. When the batteries need replaced, a
flashing 
 symbol will be displayed.
To change the batteries:
1. Lift up the front flap to reveal the battery compartment. Open the
battery compartment by inserting a coin underneath the bottom
right edge of the flap and lift it out.
2. Replace the used batteries with 2 new AA LR6 Alkaline Batteries
(Duracell are recommended) and push the battery compartment
firmly back into the front of the unit.
RESPECT YOUR  ENVIRONMENT!
Take care to dispose of used batteries carefully.The RF Chronotherm has a permanent memory to keep your program
settings while you change the batteries, you should never need to
reprogram. However, if you  take more than one minute to change
them, you may need to correct the time by moving the slider to the
DAY / 
 position and pressing the 
 + button.
I want to use the table stand instead of wall mounted
bracket. Where can I position the room unit?It is important to keep the room unit in a location where reliable RF
communication was proven. Advise your installer where would you like
to position the room unit and he will check if the RF communication is
reliable in the selected location(s).How do I remove the RF Chronotherm from the
table stand or wall bracket?After programming is finished always replace the RF Chronotherm
back on the wall holder or table stand.HC60NG Relay Box Controls Layout
