5.1. Temperature display
Measured temperatures from both connected
sensors are presented on PCSol 150 linear display
indicators.
Number of lit segments increases along with the
temperature rise. Measured temperature is shown
with the step of 10°C for T1 sensor (collector’s
temperature) and 5°C for T2 sensor (DHW
reservoir temperature). Subsequent segments of
the indicator indicate respective temperatures
reached in the sensor. Examples of the
temperature display is presented in Fig. 5.3, Fig.

5.2. Screen navigation
Screen position selection for edit is done
by knob turning. Cursor position in selection mode
