INSTALLATION AND OPERATION MANUAL
11
III. SERVICE FUNCTIONS
SERVICE menu (item 3) enables previewing and altering advanced functions of the
thermostat.
Settings introduced by a technician at the time of the thermostat start-up are enough for the
proper control of room temperatures without the need to correct any of the options.
Therefore, the less experienced user does not need to enter service menu in order to take
the full advantage of the thermostat capabilities. If more serious modifications are
necessary, it is recommended to consult a technician or our technical service.
It is recommended to be very careful when modifying the service or installation settings,
especially those unlisted above and to do it only if necessary.
Caution! Any intervention may cause malfunction of the system and in extreme
cases may result in damaging some elements of the system.
1.
OPERATING TIME (item 301)
–
operating time counter of a heating (air-conditioning)
device
Checking the total time of relay operation.
In order to reset the counter, after displaying the time press OK shortly. After pressing OK
again, the counter is zeroed.
In order to exit this item without resetting the counter, hold OK for 2 s.
2.
MANUAL SETTING (item 302)
–
setting times and temperatures to be selected with
the button (see: II. User functions, point 3.)
TEMPERATURE
–
three temperatures of manual setting
–
factory setting: 18°C, 20°C and
22°C.
DURATION
–
three duration values of manual setting
–
factory setting: 30 min, 2 h and 8 h.
LIMIT
–
a temperature range not to be exceeded when setting the temperature manually;
default range: 5-
35°C.
This setting in combination with a coded interlock (SERVICE / PIN / YES / MENU ONLY)
prevents excessive temperature changes.
3.
MODES (item 303)
–
operation mode settings
AIRING
–
(see: Section II. User functions, point 5b.)
•
AUTO
–
automatic activation of the airing mode in case a rapid drop of temperature is
detected
–
this mode is turned on only when a heating device is switched on;
•
MANUAL
–
airing mode will be turned on only manually by a user (item 102);
•
DURATION
–
duration of airing from 5 to 60 min
–
irrespective of the method of
switching it on.
ECO
–
(see: Section II. User functions, point 5e.)

–
(see: Section II. User functions, point 5d.)
4.
YEAR TIME
–
(item 304)
–
setting the current date and time (see: Section II. User
functions, point 2a.)
5.
ALGORITHM
–
(item 305)
–
setting the thermostat operating algorithm (see:
Section II. User functions, point 2e.)
HYSTERESIS
–
the hysteresis settings: from 0.1 to 5ºC for heating or cooling.
PWM
–
algorithm, which shortens the heating time proportionally to the temperature
increase. The closer the temperature to the preset one the shorter the cycles and longer
time intervals between switch-ons.
