VII. How to use the controller
V.a) Principle of operation
The main task of ST-292 room regulator is to maintain the pre-set temperature of the
room by sending a signal to the heating device (contact opening) when the desired
temperature is reached. In such a situation, the heating device is switched off (if the
regulator is connected to the CH boiler controller, the CH boiler enters sustain mode).
V.b) Operation modes
The regulator offers the following modes of operation:
 Day/night mode
In this mode the pre-set temperature value depends on the current time of the day. The
user may set different temperature values for the daytime and nighttime (comfort
temperature and economical temperature) as well as define the exact time of entering
day mode and night mode.
In order to activate this mode, press EXIT button until day/night mode icon appears on
the main screen.
 Weekly control
This mode enables the user to define the time when the pre-set comfort temperature
and the pre-set economical temperature will apply. The user may set 9 different
programs divided into three groups:
- programs 1÷3 – daily temperature values are set for all days of the week;
- programs 4÷6 – daily temperature values are set separately for the weekdays
(Monday-Friday) and for the weekend (Saturday-Sunday);
- programs 7÷9 – daily temperature values are set for each day of the week
separately.
* The display shows the hours when the comfort temperature applies. In the remaining
time period economical temperature applies.
