Programme settings

P rog settings

The MC200 has 14 programmes, each of which can be
assigned to any day of the week. Each programme can be
given an ON time, an OFF time and a set temperature. The
user may organize the programmes in any way that suits.
The simplest would be one programme ON in the morning,
OFF at the end of the afternoon, active Monday to Friday.
If two or more programmes are active at the same time,
for instance one is ON all day and another is ON between
11:00 and 13:00, then the set temperature of the second
programme will apply between 11:00 and 13:00, and the
set temperature of the rst programme will apply during
the rest of the working day.

Programme times increment in 5 minute steps.

Extension time (if set) applies when all programmes have
reached the end of their set period for that day.

Optimum start applies at the beginning of the rst
programme to switch on and optimum stop applies at the

number, ensuring that the holiday shutdown date is not
automatically repeated the following year.

During the holiday period the heater will only operate
if the temperature falls below the frost temperature
and if frost temperature operation is selected “ON” in
the engineer menu. The night temperature setting is
ignored during holidays. During the holiday period,
manual operation of the fan or heater is permitted. Any
manual operation still on at midnight will be automatically
cancelled.

Run Mode

Run mode: WINTER

The MC200 has three Run modes: WINTER, SUMMER and
OFF.

Winter - the heating operates when any programme is in a
“HEAT ON” period. The heating also operates to maintain
the Night Temperature if this has been set. The heating
also operates when the temperature drops below the frost
temperature.

NOTE: Summer/Winter mode has no
connection with the clock change from GMT to
BST.

Summer - the fan operates to circulate air when switched
on manually. With certain types of heater or certain types
of installation, Fan-only operation may not be appropriate
and the fan control circuit should not be used.
In SUMMER the heating never operates unless the
temperature drops below the frost temperature.
During commissioning the frost temperature operation will
be set to be ON or OFF. If the frost setting is OFF, the heater
will not operate under frost conditions in any User mode.

OFF - the heater never operates unless the temperature
drops below the frost temperature (see above)

• Press the + or - button to change between WINTER,
SUMMER & OFF.
