the connection points
NO
and
COM
of the receiver output relay are closed at temperatures
below 21.8 °C (heating is turned on) and 230 V AC is displayed on the output for that zone.
The
NO
and
COM
conection points are opened at temperatures above 22.2 °C (heating
is turned off) and the 230 V AC voltage at its output for that zone is turned off. In cooling
mode, the relays switch exactly the opposite way.
The closed status of the output relay terminals
NO
and
COM
is indicated by the or
icon in the lower left corner of the display, depending on the selected operating mode.
4. PROGRAMMING THE THERMOSTAT
4.1 A brief introduction to programming
•
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. For
each day, beside 1 fixed (
PROG
) switching time, 6 adjustable (
PROG
‒
PROG
) switching times can be set. For all switching times a different temperature can
be assigned between 5 and 40 °C, in 0.5 °C increments. The temperature set for a
given switch will remain valid until the start time of the next switch. Accordingly, the
thermostat will keep the temperature set for switching time
PROG
until switching time
PROG
is reached. After switching time
PROG
the temperature selected to switch
PROG
will be valid until the time of the next switch (
PROG
).
