VII. How to use the controller
VII.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/cooling device (contact opening) when the desired temperature
is reached. In such a situation, the heating/cooling device is switched off (if the regulator is
connected to the CH boiler controller, the CH boiler enters sustain mode).
If the regulator is used in heating mode, it may cooperate with the underfloor heating sensor.
In such a case, the contact remains closed when the floor temperature is below the minimum
threshold. After the threshold value has been reached, the contact remains closed until the pre-
set room temperature is reached. If the floor sensor temperature exceeds the maximum value,
the regulator opens the contact regardless of the current room temperature.
NOTE
In order for the underfloor heating functions to be available in the controller menu,
it is necessary to connect an additional sensor to the floor sensor contact.
VII.b) Operation modes
The user has three operation modes to choose from:
 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.
