7.2.5 Maintenance and Service

In normal operation, the thermostat is maintenance-free.
To prolong its lifecycle, the following precautions should be observed:

* If a voltage range (0 – 0.5 or 9.5 – 10.0 V) is indicated, the applied voltage must be within the given limits.
However, if a single value (e.g. 1.0 V) is indicated, the applied voltage must be within +/–0.1 V of the given value to achieve the assigned demand setting.
Examples: "Stop" can be achieved with any analogue input value greater than 0 V and less than or equal to 0.5 V;
40 % demand can be achieved with any analogue input value greater than or equal to 0.9 V and less than or equal to 1.1 V etc.
