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.

1. Installation of Transmitter
Locate and fit the transmitter to the wall 1.5m from the floor, taking into consideration where
not to position the transmitter as shown the next diagram.
The following can reduce, deflect or block radio frequency signals between the transmitter
and receiver.
a. Steel reinforced walls.
b. Large metallic objects e.g. kitchen appliances, filing cabinets, mirrors etc.
c. Maximum distance between Receiver and Transmitter is:-
i. In open air 50m.
ii. In building 20m to 30m depending on radar obstruction.
