EUROSTER Q7 –INSTALLATION AND OPERATION MANUAL 10
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.
MANUAL SETTING (item 302) –setting times and temperatures to be selected with
the button (see: I. 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) pre-
vents excessive temperature changes.
MODES (item 303) –operation mode settings
AIRING –(see: Section I. 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.
HOLD –(see: Section I. User functions, point 5d.)
ECO –(see: Section I. User functions, point 5e.)
YEAR TIME (item 304) –setting the current date and time (see: Section I. User
functions, point 2a.)
ALGORITHM –(item 305) –setting the thermostat operating algorithm (see: Sec-
tion I. User functions, point 2e.)
HYSTERESIS –the hysteresis settings: from 0.1 to 5ºC for heating, cooling or floor sensor.
PWM –algorithm, which shortens the heating time proportionally to the temperature in-
crease. The closer the temperature to the preset one the shorter the cycles, and longer the
time intervals between switch-ons.
PWM CYCLES –allowable number of cycles during one hour is from 2 to 20. An hour
divided by the number of cycles gives duration of one full cycle.
MIN. PWM CYCLE –minimum duration of one cycle: from 1 to 10 minutes. In case of
using devices that require a minimum start-up time or an operation lasting not less
than a specific period, take it into account and adjust this parameter properly.
PWM LIMIT –from 0.1 to 10ºC – when the room temperature drops below the preset
one by a whole limit value, then the heating device is switched on for a complete cy-
cle; when the temperature increases, then the cycle is shortened proportionally and
the time intervals between the switch-ons are shortened.
LEARNING (item 306) –automatic storing of selected temperatures and their time
ranges (see: Section I. User functions, point 2c.)
The thermostat stores the duration of a preset temperature and automatically establishes a
time range in which this temperature is effective. This range will be effective for all days of
the Mon-Fri period or Sat-Sun period depending on the period in which the setting was es-
tablished and repeated.
