1. On these instructions
The following symbols and marks are used in these instructions:
- Action instructions are numbered consecutively.
√ Results of actions are identified by this check mark.
- Enumerations are identified by this point.

Note!
Information on the economical use of the radio timer thermostat display is identified by this sign.

Operation with radio controller
Information on altered behaviour of the radio timer thermostat display when operating with the radio controller.
2. How the radio timer thermostat display functions
Your radio timer thermostat display functions similarly to a time delay switch – at specific times which can be set, your heating system is regulated by the radio timer thermostat display to three temperatures which can be set.
- The comfort temperature is usually used for the daytime, put more precisely for the periods when you are present.
- The lowering temperature is usually used for the night. It is also called the economy temperature.
- The anti-freeze temperature is usually used for longer periods of absence (e.g. holidays). The temperature is just high enough to protect the heating system against freezing.

- If a group of days covers an existing switching time, the existing switching time is overwritten without any query.
- If a switching time is placed on the moment of an existing switching time, the existing switching time is overwritten without any query.
- If an existing switching time is modified and placed on a moment which is already occupied by an existing switching time, the existing switching time is overwritten without any query.
- Redundant switching times (switching times in time program which do not cause a change in the temperature step) are not recognized or removed automatically. You must search for switching times of this kind and remove them yourself if further switching times are required.
