Description
this algorithm is that the heating process begins with the TRV
heads opening and ensures the flow in the system before the
boiler starts. The system also turns off the boiler via the RX10RF
(RX1) module before all TRV heads are closed.
AUTO
Default setting (AUTO) means system decides itself which
control algorithm to choose:
• if thermostat works in the system together with RX10RF
(RX1) (which controls boiler), then TRV heads will be controlled
according to „OFF" algorithm described above,
• if there is no RX10RF (RX1) - then thermostat selects the
self-learning algorithm „ON" (Advanced Self Learning Control)
described below
ON
Advanced Self Learning Control - an advanced self-learning
algorithm.
This algorithm is intended for systems that are not equipped
with the RX10RF (RX1) module. Hydraulic system must have
by-pass - boiler still can operate when all TRV heads are closed.
The correct operation of the algorithm consists in double
calibration process of the TRV head:
• standard - during TRV head installation on the valve.
• precise - to self-adapt to room conditions and maintain a
stable temperature.
Advanced calibration can take several hours (or even more if 1
thermostat controls several TRV heads simultaneously). While
thermostat is performing calibration process, message „RADIA-
TOR TRV CALIBRATING" appears on the display.
WARNING! Calibration process performs automatically. There is
no need to force it manually.
S1/S2 input can work in various configurations:
DISABLE - S1/S2 input is off.
FLOOR SENSOR - S1/S2 input is used for floor temperature
sensor connection (e.g. FS300 - NTC 10kOhm). Thermostat
maintains temperature in the room and additionaly (by floor
sensor) prevents floor against overheating or overcooling which
may cause discomfort or floor damage.
EXT SENSOR - S1/S2 input is used for external temperatu-
re sensor connection (e.g. FS300 - NTC 10kOhm). When an
external temperature sensor is connected, thermostat will
display temperature measured by this sensor and will ignore
the internal built-in sensor. An external temperature sensor can
be used when thermostat is controlling room to which we don't
have access. Please note that if no external sensor is connected
and you have chosen to use the S1/S2 input as „EXT SENSOR",
the temperature will not be displayed.
OCCUP SENSOR - an external volt-free contact is connected to
the S1/S2 input (e.g. hotel card, occupancy sensor).
When S1/S2 contacts are closed, thermostat is in normal
operation mode e.g. schedule mode or manual mode.
When S1/S2 contacts are opened, thermostat activates standby
