protection function switches on the boiler for a one minute period
at 12:00 p.m. every day outside the heating season. (The pump
protection function can accomplish its task only if the boiler is in
working order in the summer, too. It is reasonable to set a low
temperature level on the thermostat for this period, e.g. +10°C, to
prevent the boiler from unnecessary start-ups when the weather
turns cold temporarily).
4. PROGRAMMING THE THERMOSTAT
Programming means the setting of switching times and selection of
accompanying temperature levels. The device can be programmed for
a one-week period. Its operation is automatic, and it will cyclically repeat
the programs that have been keyed in. Six separate switching times can
be selected at your discretion for each day of the week, and a separate
temperature can be set for each switching time. The temperature set for a
given switch will remain valid until the time of the next switch. Accordingly,
the thermostat will keep the temperature set for switching time P1 until
