Product Overview
E901 is a programmable, surface-mounted electronic room thermostat, used for wireless control of heating devices (e.g. gas, oil boilers, heat pumps) or cooling devices. It has the function of creating your own schedules. Thanks to the built-in algorithms, it offers much better temperature control accuracy than traditional mechanical thermostats. Please read these instructions carefully before using the device for the first time. The thermostat should use 2xAA, 1.5V alkaline batteries. Rechargeable batteries are not allowed.

Please note:
The ideal position to thermostat mounting is about 1,5m under floor level far from heating or cooling sources. Thermostat can’t be exposed to sunlight or any extreme conditions like for example draft.
Because of fire and explosion risk there is not allowed to use thermostat in atmosphere of explosive gases and flammable liquids (eg coal dust). In case if any of listed dangers occur you have to use additional protection measures anti-dust and explosive gases (tight cover) or prevent their formation. Furthermore, thermostat can’t be used in condensation of water vapor conditions and be exposed to water action.

E901 FULL USER MANUAL
Operation
6.1 Manual mode There are two temperature setpoint levels at our disposal. In manual mode chosen setpoint temperature level is maintained permanently until user changes operation mode or set a different temperature for each level.
– Comfort Mode – in this mode, the thermostat is to maintain a constant day temperature. When the temperature is set manually, e.g. 23°C, the thermostat maintains it until user switches to another operating mode or set a different temperature, e.g. 21°C.
– Economic Mode – in this mode, the thermostat is to maintain the reduced (night) temperature. When the temperature is set manually, e.g. 17°C, the thermostat maintains it until user switches to another mode or set a different temperature, e.g. 19°C.
6.1.1 Comfort mode
In the comfort temperature mode, the thermostat is to maintain a constant day temperature. The comfort temperature level is indicated by sun icon. To set the comfort temperature, see the steps below:
1
2

E901 FULL USER MANUAL
6.2 AUTO mode – two schedule types
– AUTO Mode – In the automatic mode, the thermostat maintains the set temperature according to the schedule selected by the user. You can choose from 2 types of schedule to manage the temperature during the week.
6.2.1 First type schedule
First type schedule mode is represented by timeline – 24 hours of a day. Empty,,boxes”means hours where Economic (Moon) setpoint temperature will be maintained, black,,boxes”means hours where Comfort (Sun) setpoint temperature will be maintained.
There are three different configurations in a schedule type 1:
· Two different programs (timelines), separate program for working days (Monday to Friday) and separate program for weekends (Saturday to Sunday) · Individual programs (timelines) for each day of the week · Same program (timeline) for the whole week
6.2.2 Second type schedule Schedule type 2 enables the programming of 6 time intervals per day, with precision up to 10 minutes. Each of the 6 time intervals allows you to set a different temperature (schedule type 1 is limited to switching between two setpoint temperatures (SUN/MOON) at full hours time periods).
When creating a schedule type 2, you must define time and temperature setpoint (thermostat will start to maintain given setpoint temperature from given time setting). There are three different schedule configurations:
· Two different programs, separate program for working days (Monday to Friday) and separate program for weekends (Saturday to Sunday) · Individual programs for each day of the week · Same program for the whole week

In this chapter you will find detailed information on the built-in factory programs (1-3) in the E901. These are pre-programmed time settings for the comfort and economy temperature that can be assigned to a selected day. To set up the program, see the steps below. The black squares on the timeline indicate the operating time for the comfort temperature mode, while the absence of them – for the economy temperature mode. Under the chart of each program, there is time (hour) when each mode is active. By default, program 1 is set for each day of the week.

Switching time is represented by timeline. See steps below how to programm your own schedule:
Example: below, program 4 will be defined for the MON – FR period with a comfort temperature from 8:00 to 16:00 and economic from 0:00 to 8:00 and 16:00 to 0:00. Programming starts from 0:00.
