RT520 is a digital room thermostat used to control the room temperature. The thermostat works by maintaining comfortable conditions in the room according to a set schedule or according to the temperature set by the user. The thermostat is directly connected to the boiler.
FEATURES:
OpenTherm communication (OT+ 4.0) enables two-way communication between the boiler and the thermostat.
The thermostat modulates the boiler output to achieve maximum efficiency and comfort. The thermostat has automatic detection of the OT + protocol, display of boiler error codes and DHW regulation.
