CM61RF
WIREFREE CHRONOTHERM
PRODUCTSPECIFICATION SHEET
FEATURES
• Attractive slim styling makes it ideal for location in
any home
• Proven narrow band, multi-frequency synthesiser
based technology for communication jamming
avoidance
• As no wired connection needs to be provided
between room unit and boiler, CM61RF can be
installed without disrupting the room decor
• 6 daily independent time and temperature level
changes let you set 6 time and temperatures pairs to
suit your life style
• Temporary setpoint temperature change overrides
the programmed temperature till the next switch
point
• Holiday button provides energy savings by
reducing the temperature for 1 to 99 days when
people are on holiday, returning to normal operation
(AUTO or MANUAL) on the day of return
• EEPROM memory holds the user program
indefinitely even when the batteries are removed
• OFF mode has an integral fixed frost protection
setting at minimum 5
°
°°
°C (installer adjustable) so that
pipes in the house will never freeze in winter.
• 24...230V 8A resistive, 3A inductive SPDT relay
provides compatibility with most domestic central
heating systems without stocking many different
models.
•
T
he wall mounted holster allows removal of the
CM61RF from the wall for armchair programming
• The HC60 relay box may be surface or wallbox
mounted
• Frost protection is ensured when the slider is in the
OFF position. Frost protection setpoint may be
adjusted by installer (minimum setting 5
o
C)
• Installer Set-Up Mode allows extra functions to be
set at the discretion of the installer to match the
consumers applications:
• Optimisation
• Pump Exercise
• Upper / Lower Setpoint Limit Adjust
• Temperature offset
• Minimum ON time
• Cycle rate
• Heat / Cool Operation
• Proportional Band Width
• Failsafe mode for communication loss
• Every room unit can be bound with several relay
boxes (e.g. to control several electric heating
panels)
• CM61RF can be used with Automatic Time Setting
module (Q6667B1007)

1RF Chronotherm is designed to provide automatic
time and temperature control of heating or cooling systems
in villas and apartments. It can be used as a part of system
in conjunction with gas and oil boilers, circulation pumps,
variety of valves and actuators or electric heating systems
(<10A).
The radio frequency controlled
CM61RF system consist of
a room unit T6661C and relay box R6660C (HC60). No
wiring to the room unit is required. Installer needs to wire
only the relay box to a controlled device (e.g. boiler) and
mount the room unit in a suitable location where the RF
communication is reliable.
The
CM61RF display, buttons and slider layout are identical
to CM61 ‘wired’ chronotherm The unit is ideal for consumers
who want reliable precise temperature control from a simple
to program easy to use product.
