(activated) is acknowledged by pressing the “SET” button. (After approximately
10 seconds settings are automatically acknowledged and the device goes
back to the main screen). By pressing the “RESET” button, the pipe protection
function is reset to factory default setting (“HP:OFF”).
To prevent the pump from sticking, the activated pump 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).
3. 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 switching time P2 is reached. After
switching time P2 the temperature selected to switch P2 will be valid.
NOTE! The software of the thermostat will only enable increasing consecutive
times to be set, in accordance with the serial number (P1; P2; etc.) of the
switches.
With factory default settings the device will perform the following switches
each day of the week:
P1 7:00 20°C P4 15:00 19°C
P2 9:00 17°C P5 17:30 22°C
P3 12:30 20°C P6 23:00 17°C
The following diagram shows the temperature pattern according to factory
default settings for 24 hours a day:
The temperature pattern, of course, can be freely modified so that a
temperature curve is available for each day of the week to meet your needs
in the best possible way.
