Short Description
Short description Radio Thermostat Mechanical Clock - Transmitter
The Radio Thermostat Mechanical Clock is a 7 day radio frequency (RF)
wireless thermostat/ timer which communicates with a special receiver
designed to replace the universal digital timer fitted to most of Ferroli’s
combination boilers.
The Radio Thermostat Mechanical Clock is battery powered and can be
sited wherever conventional room thermostats would normally be sited.
In combination with the Radio Thermostat Mechanical Clock receiver,
the Radio Thermostat Mechanical Clock transmitter creates a room
thermostat clock of highly advanced technology. The device is wireless
and controls the heating boiler via radio, providing comfortable room
temperatures.
Safety Instructions
Safety Instructions
Both receiver and transmitter should be fitted by a competent person.
It is imperative to observe the generally applicable safety measures,
such as: Before starting any work on fitting the receiver, switch off power
supply and secure against switching on.
Do not use any metallic and sharp pointed objects for the operation of
the keys.
For technical data, see label on the unit or data sheet.

Installation
ATTENTION!
Note: If no reception is possible it has to be checked whether any
metallic cupboards or other metallic obstacles may interfere.
Note: During a demand the LED will show a solid light.

Location
Emergency running mode
If no valid radio signal is received from the transmitter, the receivers LED light will flash
every half second. After 1 hour the boiler will operate in ‘Emergency Mode’ (heating for 4
min. and off for 9 min.). Ensure the batteries are ok, replace batteries if necessary.
Radio link installation
1. Press receiver button and hold down for 2
seconds. The LED flashes twice. Then release
the button. The LED remains on between 1 and
10 seconds. When a correct link between the
transmitter and receiver has been established
the LED goes off. Subsequent RF transmissions
are indicated visually by a momentary flash of
the LED (approx every 5 seconds).
2. Install the batteries onto the transmitter, the
receiver LED will go out. The radio link between
the transmitter and receiver is now established.

Installation
Mounting the wall plate
Locate and fit the transmitter, taking into consideration where not to position
the transmitter as shown. 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, filling cabinets, mirrors etc.
C. Maximum distance between the receiver and transmitter is:-
1. In open air 50m.
2. In building 20m to 30m depending on radar obstruction.

Setting the time
Note: Panel (A) slides back to reveal reference instructions (B).
Slide cover (D) off the transmitter.
Turn the outer dial clockwise to set the clock hands to the correct time.
Ensure the time corresponds with the correct time on the 24hr dial.
3.00pm = 15.00 not 3.00.
Note: Do not rotate anti-clockwise or damage may occur to the unit. Rotate
the minute hand with your finger to set the exact time.

12
Set Heating ON/OFF Periods
Select the ON times by pushing the tappets to the outside.
Select the OFF times by pushing the tappets to the inside.
Above shows the clock set as follows:
ON 3.00pm to 10.00pm (15.00-22.00)
OFF 10.00pm to 5.00am (22.00-5.00)
ON 5.00am to 8.00am (5.00-8.00)
OFF 8.00am to 3.00pm (8.00-15.00)

13
Set Max/Min Room Temperatures
Manual Switch
Maximum setting - Rotate the Maximum dial to
give the required room temperature up to 30oC
when heating is on.
Minimum setting - Rotate the Minimum dial to
a lower temperature down to 5oC to ensure that
when the heating is off a minimum room
temperature is maintained.
The clock has a manual heating ON/OFF switch which operates as follows:
Timed Position - Heating ON/OFF as set by tappets.
Max Position - Heating ON continuously.
Min Position - Heating OFF, but a minimum set room temperature is
maintained.
