RF Programmable Thermostat
What is an RF Programmable Thermostat?
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 CM61NG can therefore be installed without disrupting your room decor. These instructions explain how to program and operate your CM61NG to 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 CM61NG while 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 firing
•Attractive slim styling compatible with any room decor
•6 daily independent temperature levels let you set any 6 temperatures from 5 to 30°C to match your daily lifestyle
•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 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.
