FACTORY PRE-SET PROGRAMME
The TP75H range of programmable room thermostats are provided with a factory pre-set
programme of switching times and temperatures, so that, once the clock has been set and the
TP75H returned to the RUN mode, the heating system will be controlled at the times and to the
temperatures of the pre-set programme, as shown in the following table and indicated by the
fine line in the diagram below.
The instructions on the previous page show how to change the times and temperatures to the
users requirements.
The table should be used to record the users programme. If the TP75H has been configured
for 5/2 day control only days 1 and 6 need be recorded.

In the above diagram the heavy line indicates what a typical user-set programme might be. Note
that event 2 has been moved to 14:00, that events 3 & 4 have also been moved to that time,
and that the following control temperature will be that of event 4.
It is possible to move events past midnight into the following day, when the day number will blink
in the display, see the display diagram in the notes on setting event times.
NOTES ON SETTING EVENT
TIMES
If, during the event checking and setting
procedure, no buttons are pressed for
more than two minutes then the TP75H
will return to RUN mode automatically. If
this appears to have occured, it is
advisable to re-check the programme to
ensure that it is as required.
When setting event times and
temperatures it is not possible to set
event times out of chronological order.
Event 1 may be set at any time from 0:00
to 23:59 (but would normally be in the
morning).
Event 2 may be set at any time between
event 1 and 23 hours, 59 minutes after
event 1.
Event 3 may be set at any time between
event 2 and 23 hours, 59 minutes after
event 1.
Event 4 may be set at any time between
event 3 and 23 hours, 59 minutes after
event 1,.... and so on.
If the event time being set is moved past
midnight into the following day then the
number of the following day will blink.
When using the + button to adjust events
1 to 5 and the event time being adjusted
becomes the same as the following event
time, then both are changed
simultaneously. This applies to all
subsequent event times reached and is
demonstrated in the diagram on the left.
When using the - button to adjust events
2 to 6 and the previous event time is
reached the - button ceases to respond.
The factory pre-set programme may be
reinstated by pressing the recessed R/S
(reset) button. This will however reinstate
all the factory pre-set conditions, so that
the clock type, temperature scale and
optimum start period (if enabled) may
also have to be re-set.
