Danfoss CP10C User Instructions

SELECTING THE OPERATING MODE

Behind the flap are two SELECT buttons, one each for Central Heating

( ) and Hot Water ( ).
The operating modes available are:
ON - The output is on constantly.
OFF - The output is off constantly,

unless +1HR is pressed.
AUTO - The output switches on and off to the set programme.
ALLDAY - The output switches on at Setting 1, then stays on

until Setting 4.

MANUAL OVER-RIDES

While in OFF, AUTO or ALLDAY modes the plus one hour (+1HR)
button can be used to switch from off to on for just one hour, or to
extend an existing on period by one hour. The extra hour is cancelled
by pressing the button again, pressing the MAN button, or when an on
event is reached.

While in AUTO or ALLDAY modes pressing the manual (MAN) button
will switch an output which is on to off, and vice versa. This over-ride
will last only until the next programmed switching event is reached,
when the automatic programme will resume control, or until the button
is pressed again.

When the above over-rides are selected a bar appears in the display
against the appropriate legend.

RESET

Should the unit be disconnected from the mains a small battery

symbol will blink on the left hand side of the display. After the second

midnight, i.e. between 24 and 48 hours, the display will go blank and

the unit will lose its settings. When mains power is restored it is

recommended that the unit be reset by lowering the front flap and

using a small non-metallic object, e.g. matchstick, press and release

the recessed reset button (marked R/S). This installs the factory pre-

set programme and sets the time to 12:00pm on Monday (MO). The

outputs will be OFF, (see Fig. 1). Note that the colon between the

hours and minutes is blinking. This means the unit is in RUN mode and

will switch the Central Heating and Hot Water on and off in accordance

with the programme. The colon only blinks in RUN mode.

CHOICE OF 12 HR OR 24 HR CLOCK

At any time during RUN mode the time displayed can be toggled

between a 12 hour clock with am/pm indication or a 24 hour clock by

pressing and holding both DAY and NEXT ON/OFF buttons for 1·5

seconds.

G.M.T. / B.S.T.

While in RUN mode the change from Greenwich Mean Time to British

Summer Time and back is achieved by pressing and holding the +

button to add one hour in the Spring, or the - button to put the clock

back in the Autumn. After the first time this change has been made this

feature will only allow the clock to be changed in the correct direction.

Take care when making this change for the first time. If it is made in

the wrong direction the unit will have to be reset and any user-settings

re-entered.

SETTING THE CLOCK & PROGRAMMES

1) Pressing PROG once enters SET TIME mode, see Fig. 2. While

setting the time, pressing and releasing the + or - buttons will

change the time by one minute; pressing and holding down + or

- will change the time quickly in ten minute steps. (This also

applies when adjusting the ON/OFF times). Use DAY button to set

day. When the time and day are correct, press the PROG button

once to start the clock and go to SET ON TIME mode.

ON/OFF times cannot be set out of sequence. The limits of adjustment are:
Setting 1 (first ON) 12:00am to 11:59pm (normally in the morning).
Settings 2 to 4 (first OFF to last OFF) anywhere between the previous Setting and 23 hours 59 minutes

after Setting 1.
The - button stops responding when the previous Setting is reached, but the + button continues to its

limit, also changing any later Settings that would have been overlapped.
While becoming familiar with the Setting Sequence the ON/OFF times may become grouped together.

If this should happen use NEXT ON/OFF to select Setting 1, then check/alter each Setting in turn, using
+ or -, until the desired programme is entered.
