1. Introduction
1.1 Product Compliance
1.2 Safety Informations
Care for the natural environment is of paramount importance to us.The awareness that we manufacture electronic devices obliges us
to dispose of used electronic components and devices safely. Therefore the company has received a registration number issued by the
Chief Inspector for Environmental Protection.The crossed out symbol the trash can on the product means that the product must not be
disposed of with ordinary waste containers. Sorting waste for recycling helps to protect the environment. It is the user’s responsibility
to surrender used equipment to a designated collection point for recycling waste from electrical and electronic equipment.

4E901RF FULL USER MANUAL
E901RF is a weekly, 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 oers much better temperature control accuracy
than traditional mechanical thermostats. Please read these instructions carefully before using the device for the rst time. The thermostat should use
2xAA, 1.5V alkaline batteries. Rechargeable batteries are not allowed.
In the set:
• thermostat transmitter
• thermostat receiver
Product features:
• has 2 types of time schedules
• possibility to choose hysteresis or built-in TPI algorithm
• maximum / minimum temperature limitation
• two relay types (selectable in thermostat settings): NO (normally open) or NC (normally closed)
• has the HEATING / COOLING function
• PIN lock
• has unique transmission codes
• working range up to 60m in open space
• automatically renews the operating signal

- 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 dierent 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 dierent temperature, e.g. 19°C.

16 E901RF FULL USER MANUAL
6.2 AUTO mode - two schedule types
6.2.1 First type schedule
- 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.
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 dierent congurations in a schedule type 1:
• Two dierent 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
dierent 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 dene time and temperature setpoint (thermostat will start to maintain given setpoint temperature from
given time setting).There are three dierent schedule congurations:
• Two dierent 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
