Computherm Q3RF Operating Instructions Manual page 3

Temperature can be measured and set more precisely as
compared to simple, conventional thermostats. In heating
mode, in accordance with the selected switching sensitivity,
the thermostat switches the boiler or any other appliances
on and off below and above the adjusted temperature,
respectively, and contributes to reduce energy costs while
maintaining comfort. In cooling mode it switches exactly the
opposite way.
The information shown on the liquid crystal display
of the thermostat includes the following:
