ZONE

This submenu allows you to set the operating parameters of the zone.
2.1.

REGISTRATION

After switching on the room sensor and registering it in the zone, it will be used by the EU-T-5z WiFi controller.
2.2. ON
After switching on the room sensor, it will be used by the EU-T-5z WiFi controller. However, you can disable this sensor
by unchecking the ON option.
2.3.

TEMPERATURE SETTINGS

The function allows you to set the temperature for: holiday, economical and comfort modes, which will be valid after
switching on a given mode in Menu > Operating modes.
2.4.

PRE-SET TEMPERATURE

The pre-set temperature in the zone depends on the settings of the selected weekly schedule. However, the Pre-set
Temperature function allows you to set a separate setpoint - you will then need to turn off the schedule. It is possible to
set the temperature permanently or for a certain period of time.
2.5.

OPERATING MODE

•
Local schedule – weekly schedule assigned to the zone.
•
Global Schedule 1-5 – the ability to set several schedules in the zone.
•
Constant temperature – the function allows you to set a separate setpoint, which will be valid in the zone
regardless of the time of day
•
With time limit – the function allows you to set a separate temperature, which will be valid only for a specific
period of time. After this time, the temperature will result from the previously applicable mode (schedule or
constant temperature).
The above modes can be edited freely.
2.6.

HYSTERESIS

The hysteresis introduces a tolerance for the pre-set temperature to prevent undesirable oscillations with minimum
temperature variations (in the range of 0.1 ÷ 10⁰C) with a step of 0.1°C.
Example: when the setpoint temperature is 23°C and the hysteresis is set to 0.5°C, the zone will be assigned an
underheat status only after the room temperature drops to 22.5°C.
2.7.

CALIBRATION

The room sensor shall be calibrated during installation or after prolonged use of the controller if the displayed
temperature of the zone deviates from the actual temperature. Adjustment range: -10 to +10°C with a step of 0.1°C.
2.8.

ACTUATORS

The Actuators submenu is used to program the operation of the STT-868/STT-869/EU-G-X thermostatic actuators. We
can register up to 6 STT-868/STT-869/EU-G-X actuators in a zone. The registration process is described in detail in the
First start-up section or in the actuator manual. If you want to deregister all actuators from the zone, just select the
option Delete actuators.
