7 day, Single Channel Digital Wireless Programmer and Room Thermostat –

Part No. CT200001

The digital wireless programmer and room thermostat is a 7 day radio frequency (RF) wireless
thermostat / timer, which communicates with a receiver designed to fit in the clock aperture of the
boiler control panel. The unit can be pre-programmed to provide maximum and minimum room
temperature control. Each day can be programmed with the same – or different – time periods. The
programme can be temporarily or permanently overridden to increase or decrease the desired
temperature setting.

The batteries should operate the unit for approximately 18 months to 2 years depending on the
number of switching operations etc. Only good quality alkaline batteries should be used. When the
batteries need replacing, a low battery symbol will be displayed. After replacement, all the
programmes and temperature settings remain stored and no resetting is required.

Note: If the batteries are not replaced and no valid signal is received from the Transmitter, the
Receiver’s neon light will flash every 0.5 seconds. After 1 hr the boiler will operate in ‘Emergency
mode’ (heating on for 4 min. and off for 9 min.) until the batteries are replaced.

Note; always press the reset button after removing or replacing the batteries.

This timer is suitable for installation as a time controller for:

ATAG iC 24 Combi

ATAG iC 28 Combi

ATAG iC 36 Combi

ATAG iC 40 Combi

ATAG Economiser 27

ATAG Economiser 35

ATAG Economiser 39

ALWAYS switch off and disconnect the electricity supply to the appliance before installing the
programmer. Merely switching the boiler ON/OFF switch to 'OFF' will still leave a live feed to
the boiler.

WARNING.

This unit must be installed by a skilled electrician

in accordance with the current I.E.E. Wiring Regulations.
