2. 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 AA, 1.5V alkaline batteries. Put the batteries in the battery compartment
located under the slide cover. Rechargeable batteries are not allowed.
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 modes

Mounting screws
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.

the user. You can choose from 2 types of schedule to manage the temperature
during the week.
Comfort and Economic temperature setpoints works not only in manual mode but
also for the first type schedule mode.
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.
6.2.1 Default program settings (1-3)
Within first type schedule mode there are 9 programs available. Programs 0 to
3 are factory-defined programs that cannot be changed. 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 (see the list of factory
programs below) 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.
