There are 3 pin code protected Landlord settings available on the RT520RF Thermostat. These are Service Mode, Minimum and Maximum Temperature Settings and Receiver Manual Mode Control.
Service Mode – This is a feature that allows the landlord to set a service reminder on the thermostat that will warn the tenant when the boiler is due its annual service. When this function is active, and your boiler is due for a service, the Landlords phone number will scroll across your screen and a tools symbol will be shown.
MAX_MIN – This is the setting which restricts the maximum and minimum set point temperatures a tenant can select on their Thermostat. This is often used to control the heating costs.
Receiver Manual Mode Control – This function is used to disable the Manual Mode switch on the boiler receiver. This in turn prevents the tenant from overriding program schedules set on the Thermostat by the Landlord.

The screen will illuminate.
Press the COG button (first of the buttons from the left) SCHEDULE will be displayed.
