A Honeywell Radio Frequency (RF) programmable thermostat is a
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
a wired connection between thermostat and boiler. The
can therefore be installed without disrupting your room decor. These
instructions explain how to program and operate your
get the most comfort at the least cost.
What will the
CM61NG Programmable Thermo-
stat do for me?
Wireless connection to the boiler allows you to mount the
CM61NG in your room without disrupting the decor
Armchair programming lets you set up your
resting comfortably in your armchair
Optimum Start means that the
CM61NG will switch on your
heating system so that your desired comfort temperature is
reached at the programmed time, thus avoiding unnecessary boiler
Attractive slim styling compatible with any room decor
6 dailyindependenttemperature levels let you set any 6
temperatures from 5 to 30°C to match your daily lifestyle
Holiday button saves energy by lettingyou 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 take the batteries out
What is Optimum Start?
Instead of switching on the heating at the set time every day, the
CM61NG will delay the start time to the latest possible moment, so
that unnecessary heating is avoided. All you have to do is set the time
when you want comfort temperature and the
CM61NG will then
decide when to turn the heating on, thereby ensuring your comfort.
What if something happens to my heating system? How can I check that the
CM61NG is working?

The heat demand is sent to the relay box as a value between 0-100%.
The relay box will adjust the boiler on time to meet this requirement.
That is why the heating will be off sometimes even if the ‘flame’
symbol is displayed. To check if RF system is communicating properly
press the TEMPerature UP button to increase the set temperature a
few degrees above the current temperature. The heating should come
on after a few seconds
Switch the boiler on
Call electrical installer to check the boiler and relay box power supply
as well as the connection between the boiler and the relay box
Hook the room unit back on the wall bracket or replace the room unit

NOTE: You can control the boiler manually when the RF communica-
tion is lost:
Press the HC60NG push button to switch the boiler on and off. When
the green LED is on – the boiler is on.
Remove the battery compartment and re-insert it. If the ‘spanner’
symbol does not clear itself in a few minutes call the installer
