Worcester Bosch Mechanical RF Thermostat MT10RF 7716192037

The Worcester Bosch MT10RF is a mechanical room thermostat that communicates with the boiler over a radio frequency link rather than a hard-wired connection. It is part of the Worcester Bosch controls range and is used to set and hold the room temperature by signalling the boiler to fire and stop as heat demand changes. Because the signal is transmitted wirelessly, the unit can be sited away from the boiler position without running a thermostat cable back to the appliance.

• The boiler does not respond when the thermostat dial is turned up
• Room temperature drifts away from the set point and the boiler fails to fire
• Heating runs continuously regardless of the thermostat setting
• The wireless link between thermostat and receiver becomes intermittent or drops out
• The dial or internal mechanism feels loose, stiff or fails to click at the set point

• Confirm the part number 7716192037 matches the thermostat currently fitted, as the MT10RF is one of several Worcester Bosch control options
• Check the alternative numbers listed below against any documentation supplied with the original unit
• Verify that your boiler and receiver are compatible with the MT10RF radio frequency control before purchase
• If the thermostat is being replaced as part of a wider controls fault, check the receiver and wiring at the boiler end as well
