The Di2RF thermostat is a programmable thermostat 24-Hour
product (the same program for every day of the week) which
allows you to set up to 6 time and temperature events per day.
Clock Setting
Your Di2RF is fitted with a real-time clock, which is pre-set
at the factory. You will not have to alter the time settings.
A special feature of this real-time clock is to automatically update
the time during the summer/winter time change removing the
need to manually alter the clock.
General Operation
With the unit in Auto mode (the small arrow to bottom of screen
will point to Auto) the temperature can be changed for a short
time by using the + or - buttons. Changing the temperature in
this way will keep the Di2RF set to your new temperature
until the next pre-programmed event (at which time it will revert
to programmed temperature). The temperature you are setting
will flash on the screen. Once temperature is set, the unit will
revert to showing the current temperature. The indicator will
show on the screen if the heating is turned on.

As you can see, at 06:30 , the heating will come on to raise the
temperature to 20ºC. At 08:30, the temperature set point is
dropped from 20ºC down to16ºC, it stays at 16ºC throughout the
day, until 16:30 when the temperature increases to 21ºC. The
temperature then drops down to a night-setback temperature of
7ºC until 06:30 when the cycle repeats for the next day.
To adjust these times and temperatures
1. With the product operating as
normal in the Auto mode
press twice until the
display is flashing as shown.
The time will be flashing, use
the + or - buttons to adjust
the 1st time as required
(* small 1 in lower half of screen
shows which time period is being set
e.g. 1=1st period, 2 = 2nd period etc)
Congratulations!
The unit is now set correctly to follow your required timings.

What is a programmable room thermostat?
...an explanation for householders
A programmable room thermostat is both a programmer and a room
thermostat. A programmer allows you to set ‘On’ and ‘Off’ time
periods to suit your own lifestyle. A room thermostat works by sensing
the air temperature, switching on the heating when the air
temperature falls below the thermostat setting, and switching it off
once this set temperature has been reached.
So, a programmable room thermostat lets you choose what times you
want the heating to be on, and what temperature it should reach
while it is on. It will allow you to select different temperatures in your
home at different times of the day (and days of the week) to meet
your particular needs.
Turning a programmable room thermostat to a higher setting will not
make the room heat up any faster. How quickly the room heats up
depends on the design of the heating system, for example, the size of
boiler and radiators.
Neither does the setting affect how quickly the room cools down.
Turning a programmable room thermostat to a lower setting will result
in the room being controlled at a lower temperature, and saves energy.
The way to set and use your programmable room thermostat is to
find the lowest temperature settings that you are comfortable with at
the different times you have chosen, and then leave it alone to do its
job. The best way to do this is to set low temperatures first, say 18
o
C,
and then turn them up by one degree each day until you are
comfortable with the temperatures. You won’t have to adjust the
thermostat further. Any adjustments above these settings will waste
energy and cost you more money.
If your heating system is a boiler with radiators, there will usually be only
one programmable room thermostat to control the whole house. But you
can have different temperatures in individual rooms by installing
thermostatic radiator valves (TRVs) on individual radiators. If you don’t
have TRVs, you should choose a temperature that is reasonable for the
whole house. If you do have TRVs, you can choose a slightly higher
setting to make sure that even the coldest room is comfortable, then
prevent any overheating in other rooms by adjusting the TRVs.
The time on the programmer must be correct. Some types have to be
adjusted in spring and autumn at the changes between Greenwich
Mean Time and British Summer Time.
You may be able to temporarily adjust the heating programme, for
example, ‘Override’, ‘Advance’ or ‘Boost’. These are explained in the
manufacturer’s instructions.
Programmable room thermostats need
a free flow of air to sense the temperature,
so they must not be covered by curtains
or blocked by furniture. Nearby electric
fires, televisions, wall or table lamps
may prevent the thermostat from
working properly.
(Fig 3)
How to replace the batteries see fig 3.
Remove the battery cover using a coin. Replace the spent
batteries with 2 x 1.5V IEC LR6 (AA) Alkaline batteries ensuring
correct orientation. Replace the battery cover pressing fully home.
(Fig 1)
(Fig 2)
How do I know when to change the batteries.
When the batteries start to run low a battery icon will flash in the
display, to indicate “low battery” during this time the
Di2RF
will function normally (see fig 1).
Please replace batteries with 2 x 1.5V IEC LR6 (AA) Alkaline batteries.
When the battery icon alone is shown in the display, the batteries
are completely exhausted and the
Di2RF
will cease to
function (see fig 2). Re-activate by replacing the batteries.
